EvoHeat Going Global!
Travis McNeill and Tony Mills began the Evo Industries Australia business back in 2006 with very little expectations. It was a side project aimed to help both men support their growing families and keep them from getting bored during their day jobs.
Fast forward more than 10 years and Evo Industries Australia, better known as EvoHeat has become one of the industry leading specialists in pool and spa heating technology.
Earlier this year, EvoHeat were involved in the largest heat pump installation in Australia with 19 EvoHeat CS200 GEN2 heat pumps installed at WhiteWater World. Now over 30 slides, water-rides and pools are being heated year-round to a comfortable 27 degrees using EvoHeat’s energy efficient heap pump technology designed to provide Dreamworld with a massive 3,610kW heating capacity. This heating upgrade now saves Dreamworld over 70 percent on their annual water heating costs and cuts their existing carbon emissions by over 35 percent.
“The last few years have been particularly good for us. We have added new products to our EvoHeat range and also started up a sister company, Evo Energy Technologies, that provides top line cogeneration and trigeneration products into the Australian market. We have moved to a large warehouse to cope with the growing demand and employed more staff by extending our sales team, employing a full time Technical Support Manager, Marketing team and also a General Manager of our 270 Series hot water system range. We are already making plans to expand our Brisbane Head office and warehouse to cater for the growth”, General Manager, Travis McNeill said.
It’s not just the Australian market that has kept Evo Industries Australia busy, with a number of large heating projects also taking place in South East Asia.
“We have seen an increase in pool heating requests from overseas, particularly in the last few years. Just recently the Kuala Lumpur Aquatic Centre required a major upgrade of their pools in preparation of the SEA and Asean Para Games. Evo were contracted to upgrade their diving pool, 50m swimming pool and their training pool with our heat pump technology. One of the unique benefits of our heat pump technology is the ability to cool as well as heat which makes our product more versatile especially for aquatic and sporting facilities”, National Business Manager, Tony Mills said.
Due to their high demand, especially in South East Asia, Mr. McNeill & Mr. Mills have made the strategic business decision to expand their business with the launch of their expansion company, Evo Industries Singapore. The new branch will officially launch later this month, with their head office based in Beach Road, Singapore.
“We are extremely excited about the possibilities that Evo Industries Singapore offers. Having an office based in Singapore allows us to readily reach more of our customers. Over the last decade we have seen exponential growth and it doesn’t look to be slowing down any time soon”, says Mr. McNeill.
EvoHeat Now Heating UQ Sports Aquatic Centre!
Five EvoHeat heat pumps have been installed at the UQ Sport Aquatic Centre as part of a major redevelopment project at venue.
The UQ Sport Aquatic Centre – situated at The University of Queensland’s St Lucia campus – opened a new 25m pool in June, with EvoHeat CS200-GEN2 and CS38 heat pumps installed to heat the pool to a year-round temperature of 29°C.
The 25m pool features nine lanes for lap swimming, squad sessions and learn-to-swim classes, and is ramp and wheelchair-accessible.
“The UQ swimming community is one of Brisbane’s largest and most vibrant, and we’re delighted to offer our patrons an additional heated pool, which greatly increases capacity at the Aquatic Centre,” UQ Sport Aquatic Centre Venue Manager, Mr. Jae Marr said.
The venue’s 50m pool has also been overhauled with EvoHeat technology, with three CS200-GEN2 heat pumps installed to replace existing heating units.
The CS200-GEN2 heat pumps – the same fitted to heat WhiteWater World’s waterpark – will maintain a temperate of 27°C in the 50m Pool.
Known for their energy efficiency, reliable year-round pool heating technology, EvoHeat has secured some of Australia’s largest pool heating projects.
“Our technology is incredibly economical and has helped pave the way for sustainable heat pump technology in Australia, slashing running costs and cutting carbon emissions for thousands of homes and commercial businesses,” EvoHeat General Manager, Mr Travis McNeill said.
“With gas and energy prices on the rise, our exclusive heat pump technology offers businesses a smart and reliable heating solution,” says McNeill.
WhiteWater World – Mission Complete!
Evo Energy Technologies have recently completed the largest heat pump installation in Australia with a massive 3,610kW heating capacity at Dreamworld’s WhiteWater World, heating over 30 slides, water-rides and pools to 27 degrees for year- round warm water.
This system upgrade has seen some of the newest advancements in water heating technology replacing WhiteWater World’s gas boiler system with 19 energy efficient EvoHeat CS200 GEN2 heat pumps that now reduce Dreamworld’s water heating running costs by over 70 percent.
This cutting-edge technology has helped WhiteWater World move one step closer to becoming one of the most energy efficient water parks in the world.
On top of the environmental benefits, the smart control and monitoring capabilities will also boost WhiteWater World’s operational efficiencies. WhiteWater World can now monitor and remotely control all aspects of their water heating plant to ensure maximum comfort levels for their guests all year round.
WhiteWater World patrons aren’t the only ones to benefit from the water heating upgrade, with upgrades also taking place to the existing heating at Dreamworld’s Tiger Island and the crocodile pools. Using an energy efficient EvoHeat CS 57 heat pump the water in Tiger Island remains at a comfortable 28-degree temperature for 12 of their big cats.
This massive water heating redesign took over three months to install and involved various trades including hydraulic engineers, plumbers, electricians, BMS/Controls specialists, civil works contractors, laborers, gas technicians and design draftsman.
Team work played a major part in the successful completion of this immense installation that has resulted in 19 heat pumps online, at set point and connected to the external monitoring system.
While there are some final tweaks to the system, Paul Callander, Executive GM Commercial & Development, is delighted not only with the final results and quality of workmanship shown but how well all those involved collaborated.
“As we stand today the works undertaken have been a resounding success. This is a tremendous and sustainable step in making Dreamworld’s WhiteWater World the best waterpark in Australia. I genuinely believe this install will continue to exceed all expectations, well into the future and will encourage other businesses to follow in our footsteps,” Mr Callander said.
Turtles at Australia Zoo Wildlife Hospital on the Way to Recovery
Australia Zoo Wildlife Hospital, opened in March 2004 is a facility dedicated to the care and rehabilitation of Australian wildlife. ¬¬The hospital operates 24 hours a day, 365 days a year in order to be readily available to any sick or injured animals in need of care. From small animals to large, the wildlife hospital travels far and wide to rescue a multitude of animals. This free community service ensures that no animal is left suffering and allows them to get the best possible veterinary treatment. Receiving an average of 500 calls per month, the Australia Zoo Wildlife Hospital requires the best quality equipment to ensure that the animals are receiving the best of care.
The hospital cares for a large range of wildlife, from sea life to land dwellers. Many turtles come into the hospital needing rehabilitation. The hospital desperately needed a heat pump for their turtle pool, as the cold winter was making the water far too cold for the turtles to be comfortable. After contacting EvoHeat, it was decided that a Force 26 3 Phase heater would be the best solution to warm the turtle pool and rehabilitate the animals. The Force 26 is a high-performance heat pump with the lowest running costs, and is designed to perform all year round!
The turtles at the Australia Zoo Wildlife Hospital are bound to be happy with their new warm pools which are used for therapy and dive testing to ensure the turtles are well enough to go back into the wild before release.
EvoHeat Pumps Now Heating Tiger Island & Croc Pools!
Earlier this year, Dreamworld contracted Evo Energy to redesign their water heating systems for WhiteWater World, Tiger Island and their Crocodile pools.
This was the largest heat pumps installation in Australia to date, with the EvoHeat heat pumps heating the park’s pools, water rides and over 30 slides year round. The installation of these heat pumps cut carbon emission by 30% while also saving the park running costs of over 70% being both environmentally friendly and energy efficient.
EvoHeat is not only warming the waters of White Water World, but also keeping the animals of Dreamworld warm in their enclosures with heat pumps to keep the waters of both Tiger Island and the crocodile pools a comfortable temperature for them year round. Using an energy efficient EvoHeat CS 57 heat pump the water in Tiger Island remains at a lovely temperature of 28 degrees celsius allowing the tigers to continue to enjoy their pools no matter the climate.
Maintaining Your Pool Heat Pump
To ensure that your heat pump is always performing to the best of its ability, it is crucial that the heat pump is maintained correctly. Early maintenance prevents potential problems later down the line and will extend the units life span.
To get the most out of your heat pump, there are a variety of maintenance tips that can be used to ensure the heat pump is maintained to a satisfying standard.
Should I check my unit regularly?
It is highly recommended that your unit be checked regularly to prevent any potential issues or damages to your heat pump. Your heat pump should be ran routinely to check that it is in working order and prevent internal debris buildup.
What should I be checking?
All water inlet and outlets should be checked often for leaks when in use and not in use. Air and water should be able to enter into the system, as when it is prevented from doing so it will influence the unit’s performance and reliability.
Make sure to discharge all water in water pump and water system after use, so that the remaining water does not freeze.
If the unit is to be left idle for an extended period, it is beneficial to discharge the water at the bottom of the water pump.
After the unit has been unused for an extended period of time, the unit should be checked and filled with water fully before using it again.
The power supply and cable connection should be checked often, if the unit appears to operate abnormally or you have any concerns, turn it off and contact a qualified technician.
Do I need to clean around and on my heat pump?
Heat pump coils should be cleaned at least once a year and whenever they appear dirty or dusty. Dirty air coils will affect the unit’s performance as they will reduce airflow and the transfer of heat in either direction.
Any debris that catches in the unit’s air intake such as sticks or leaves should be cleared away. The area surrounding the heat pump should be dry, clean and well ventilated to ensure maximum performance.
The pool and spa filter should be cleaned regularly to avoid damage to the unit due to a dirty or clogged filter. Ensuring you have a clean unit will improve its efficiency and life span significantly.
Avoid exposing your heat pump to excessive streams of water flow.
Do I need to get my unit serviced?
It is highly recommended that once a year, your EvoHeat unit is serviced by a certified air conditioning or refrigeration technician. Units that are located in coastal areas may need more frequent maintenance than other areas.
During a service, a technician will check the operational pressures of the refrigeration system and give both the unit and fins a good clean to ensure that they are performing to the best of their ability.
We do not recommend that you open up your pool heat pump yourself in any attempt to service its internal components, it is always recommended to use a certified technician.
Do we have recommended service agents?
EvoHeat have a large database of recommended service agents. Please contact EvoHeat tech support on 1300 859 933 for your local service agent details.
Benefits of Swimming Pool Covers
In order to effectively reduce pool heating costs, a swimming pool cover is an extremely important and useful tool to use whilst the pool is not in use.
Evaporation is the largest factor when it comes to heat and energy loss. Pools that have a higher water temperature paired with high wind speeds and low humidity create a much faster rate of evaporation. Even indoor pools are not immune to evaporation, large amounts of evaporation in indoor pools require rooms to be ventilated to control to humidity within the room.
A pool cover on an indoor pool will also minimise the need for indoor ventilation and exhaust fans can be turned off whilst the cover is on which successively saves large amounts of energy.
By using a pool cover on both indoor and outdoor pools, it will greatly minimise the evaporation and loss of heat therefore producing savings of up to 70%! The use of a cover also will trap the existent heat in the pool therefore allowing you to run your heat pump for a shorter amount of time to reach the desired temperature – saving energy and your money!
There are many different types of pool covers available each having different capabilities. Covers that are specifically designed for pools include materials such as UV-stabilized polyethylene, polypropylene, or vinyl; all of which have vapor barrier abilities.
When choosing a pool cover, it must be considered how the pool cover will be used (e.g. cover off during the day vs. cover on during the day). Each type of pool blanket offers different benefits so it is important that you speak to a pool blanket expert.
Using a pool cover is beneficial in reducing pool heating costs, minimising evaporation, saving energy and keeping debris from entering the water; and when paired with a EvoHeat pool heater will allow for 24/7 comfort. If you are looking to heat your pool to the perfect temperature year-round, contact EvoHeat on 1300 859 933 now!
Energy savings tips for your heated pool
Did you know that if your pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature? For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature.
However, if you do not plan to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the temperature setting of the control several degrees to minimize energy consumption.
Check out some of our energy savings tips below:
• Always use a high-quality pool cover when practical. Besides providing a valuable water saving feature, a pool cover is the single most effective means of reducing your pool heating costs.
• Make sure you check your water temperature regularly. A difference of 2°C, between 26°C and 28°C, will significantly increase energy consumption.
• Monitor the water temperature of your pool in the summer time – you can reduce your heat pump usage due to warmer air temperatures.
• When the pool is not used for long periods, turn off the heat pump.
• Where possible, shelter your pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or fencing.
Maximise your pool with pool heating
A family swimming pool can bring so much joy and create memories of a lifetime but without a pool heater your pool can only be used for a limited time throughout the year. Thankfully advancements in technology have made pool heating much more affordable, energy efficient and environmentally friendly than ever before. That’s why so many Australians are now looking to extend their swim season and make their family pool even more enjoyable by investing in pool heating.
Not only does a heated pool extend your swim season and further maximise your pool investment but it also makes your pool more enjoyable especially for toddlers and elderly family members who experience water temperatures differently. The average Australian pool temperature sits at about 20°C which can be uncomfortable particularly for younger children and elderly people who are prone to lose more body heat in cooler conditions.
A comfortably heated pool allows you and your family to enjoy your family pool all year round, regardless the outdoor temperature.
Heat pumps are one of the newest pool heating technology in the market and are becoming a popular choice for those who want a reliable pool heater that offers a consistent water temperature, lowest running costs while also being environmentally friendly. Heat pumps offer flexible heating capabilities allowing users to heat their pool all year round, extend their swim season or use casually for events like a pool party.
This method of heating is extremely energy efficient and can be up to 600% more energy efficient when compared to other heating technologies like electric element & gas heating. And unlike solar pool heating, a heat pump is not reliant on the weather so it can guarantee pool heating results no matter the outside weather conditions or season.
EvoHeat are 100% Australian owned and operated company and are the industry specialists in pool and spa heat pumps. For over a decade we’ve been building a solid reputation for pool and spa heating solutions that are renowned for reducing your energy bills and delivering reliability.
If you are looking for a reliable, energy efficient pool heating solution, speak to us today and we can show you how we compare to other heating technologies in the market.
Get the facts!
At EvoHeat, we pride ourselves on service and our expert industry knowledge. We make sure we provide our customers with accurate and factual information on our products and other pool heating solutions. Unfortunately, sometimes other companies provide misleading information and we want to make sure you have the right facts and information before investing in your pool heating equipment.
Below is a letter to the Pool + Spa editor from our General Manager, Travis McNeill. This letter was in response to an article that we believe provided misleading and incorrect information (click here to view original article). So before you go ahead and invest in your pool heating equipment make sure you have the right facts!
LETTER TO THE EDITOR
I am writing this letter in response to the article ‘The future of energy and pools: is the status quo about to shift?’
I believe this article contains a large amount of misleading information and I will outline my arguments and back these up with facts and data.
Let me firstly say I am an industry professional and the company I work for sells heat pump systems for pools, so obviously I take umbrage to the message portrayed in this article. It also means that my bias may be taken as towards heat pumps, but as I will outline below the data will speak for itself.
I have no argument with the figures relating to average household energy usage (apart from the fact the energy should be measured in kWh not kW), however I do have an issue with the heated pool figures. The article states that a pool requires 8000 kW(h) of energy to maintain, but this figure is misleading as this energy is related to a full 12-month swimming season. The article goes on to espouse the virtues of solar pool heating, without mentioning that solar pool heating cannot and will not provide a suitable swim temperature 12 months of the year. To compare a 12-month heating season from a heat pump with a six-month solar pool heating season is clearly not providing an apples-for-apples comparison, and in my opinion is misleading the public significantly.
As shown at the bottom of the article the data quoted is based on an average 32 m2 Sydney pool heated to 28°C for six months of the year. This information can be entered into heat load modelling software to determine pool heating costs and energy consumption. Our company uses Poolheat heat load modelling software; this software was developed by Mechlab at the University of NSW and is considered to be the premier heat load modelling software on the market.
So let’s look at the data input for that average Sydney pool heated for six months of the year. I have assumed 25% shading on the pool each day and normal backyard location for wind exposure. I have used a bubble cover (see comments below) and assumed the cover is removed for four hours per day. In reality the cover would likely be on 24 hours per day for five days a week and possibly off for longer periods during the weekend. I have assumed electricity at 30 c/kWh for this model.
Pool location: Sydney, New South Wales
Pool surface area (m2) = 32.0
Pool volume (m3) = 50.0
Bottom colour: Light
Cover solar transmission = 0.80
Cover R value = 0.05
Filter back-flush to waste, % of pool volume/day = 1.00
Number of swimmers using the pool per day = 4
HEATING – HEAT PUMP
Minimum set temperature = 28.0°C
Heater capacity = load requirement
Heat pump COP = 6.10
Heat pump test conditions
Air temperature = 24.0°C
Water temperature = 26.0°C
Variation of COP with temperature = 0.0900/°C
Heat pump availability = all day
Heat pump operating period: Jan, Feb, Mar, Oct, Nov, Dec
General electric tariff (cents/kWh) = 30.0
The data above shows the inputs into Poolheat for our example. Of course different pools will have different outputs, but you can see the data is pretty consistent with that claimed in the article.
Now let’s take a look at that pool’s outputs. Remember the claim that the cost could be over $2000? As you can see below it is a fraction of this figure, and the power consumption of the heat pump totals only 1211 kWh per year for the six-month heating season.
12-month heating season — solar thermal won’t come close
Why are we comparing just a six-month season? Solar thermal won’t provide a comfortable swimming temperature for a period longer than six months, and even in this period can’t guarantee the pool will be at temperature. Got a pool party planned for the daughter’s birthday on a Sunday in January? Five days of rain and cloud beforehand and that pool is cold. Party cancelled; daughter crying; parents miserable. I have seen comparisons between the cost to heat a pool with a heat pump based on 12-month running time vs solar. How can you possibly compare the two given the solar only works at best 50% of the year? Solar thermal will not provide a suitable water temperature for more than six months (unless you are a penguin, or the system size is so large it covers the entire roof at great cost).
‘Free’ solar heating
The sun’s energy is free — it’s true. But you still must pump that water up onto the roof of the house, and if you have a double-storey house that is not insignificant. Our heat pump systems simply connect inline with the filtration system, and installation of a variable speed pump (which we consider another must-have for efficiency) allows low water flow for a longer period therefore eliminating any extra pumping costs for the heating. I’m not a solar pool heating expert — perhaps we could have some input on the pumping costs for solar pool heating. Solar pool heating isn’t free — there is a cost. I would like to see data showing the pumping costs for that six-month season and compare to our heat pump data shown above.
I’m going to be super conservative and say a solar pool heating system would need to run an average of two hours per day with a pump consuming 400 W of energy. 180 days x 0.4 kW x 2 x 30 c/kWh = 144 kWh or $43.20 per year. Next to nothing, right? But compare it to the 1.5 kW PV/heat pump option below. Now pump that water onto your two-storey house and see the costs rise.
PV vs solar thermal
Looking at the above example the peak heating load on the pool is October, with an average hourly load of 3.9 kW to maintain the desired 28°C swim temperature. This means that the required heat to maintain the pool in October is 3.9 kW x 24 h = 93.6 kWh of thermal energy per day.
A 5 kW heat pump would probably meet this October load if allowed to run for 24 hours a day (5 kW x 24 h = 120 kWh), but let’s go to a 9 kW model and reduce that runtime to 10.4 h (93.6 kWh/9 kW) per day to optimise the run time to coincide with the solar PV production time. This 9 kW heat pump will consume 1.5 kW of electricity to produce each 9 kW of thermal energy.
In the warmer months the result is the heat pump needs to run less often: 4.5 hours a day in November (1.7 kW * 24hrs/9 kW) and less than 3 hours a day for the bulk of the swimming season.
The average solar PV production rate in Sydney is approximately 3.9 kWh of electricity per kW of installed panels, but there is no reason to try and size the system to fully take the heat pump load. The rest of the house (and pool) uses electricity — that can always take any power not used by the heat pump, and overall will provide a much better solution than oversizing the PV system. So let’s go for a conservative scenario and install just 1.5 kW of solar on the roof for the pool, or 5.85 kWh of electricity per day. If we look at the chart below we can see that a very tiny 1.5 kW system will provide enough power to effectively offset the heat pump’s electricity usage for four of those six months. The PV will supply 1053 kWh of electricity for the six-month (180-day) period. This means a shortfall of 158 kWh for the swim season, or $47.40 per year. I wonder if the solar thermal pumping costs are more than 158 kWh per year as per my example above?
But of course the solar PV doesn’t become useless when April comes around. It keeps on producing the average 5.85 kWh for the rest of the year too — another 1082 kWh of electricity and a saving of $324.68 per year off the customer’s electricity bill.
So as you can see a 9 kW heat pump plus a measly 1.5 kW of PV solar gives the customer a guaranteed swim temp of 28°C every day of the swim season, free pool heating and an electricity bill saving of $324 (assuming no export of power). Show me a solar thermal system that can provide that.
Instantaneous vs aggregated energy
Some may comment that my approach to electricity produced vs electricity consumed is not based on instantaneous production. That is at any given time the 1.5 kW of PV may or may not be producing electricity that the heat pump is using. But given the rest of the house will be using electricity it’s very safe to assume that the small 1.5 kW PV system will not export power onto the grid and therefore provide the same net benefit to the homeowner, and the overall grid in general. Given the actual energy used by the heat pump is actually very low it’s really a moot argument and really not worth mentioning (other than me being my usual thorough self).
Return on investment
An important factor in any decision is ROI. Of course we all want to be more sustainable but the hip pocket must benefit too. I’m not going to dive into exact cost comparisons between the two options but given all the pros and cons listed above and below the decision is a no-brainer. How much extra will a client pay for a 9 kW heat pump and 1.5 kW of PV solar compared to a solar thermal system? Not so much that the $324/year savings (plus the offset for the solar water pump at $43.20), and all the other benefits, fail to stack up.
Blanket vs no blanket
The argument may be taken that the figures quoted in this article apply to a pool without a blanket, but this is counterintuitive to the whole crux of the article. The article is about saving energy and sustainability. Why would you not insist on a pool cover? The best form of heating for any pool is a pool cover and this will also save large amounts of water and chemical dosing.
A common analogy we use when discussing covers with clients is would you try and heat/cool your home with all your doors and windows open? Of course you wouldn’t. Well, it’s the same with a pool. A cover should be mandatory on any pool that is heated, or any pool that has a goal towards sustainability/efficiency.
Thermal blanket vs bubble blanket
Thermal blankets are great for insulating the pool heat loss from the surface, but don’t allow any heat from the sun into the pool if it’s an outdoor pool. Most domestic pools get at least some sun each day and a bubble blanket allows approximately 80% of the thermal energy into the pool. Given the majority of domestic clients will use the pool very occasionally during the week the cover should be left on during the working week.
Why would you recommend to a client they cover the pool with a 0% thermal transmission cover and effectively block free solar energy — energy you don’t need to get by covering your roof with black plastic? I would only recommend a thermal blanket to a commercial client who takes that blanket off every day and puts it back on every night, or a domestic client with a very heavily shaded pool.
Guaranteed swim temp
I’m yet to find a solar pool heating system that can provide a guarantee that 100% of the time the pool will be at the desired temperature. It’s just not possible. With a heat pump solution we can provide this guarantee and do to all of our clients.
Would you buy a car if it only worked 75% of the time? A computer? A client’s expectation of utilising their pool is on demand not on the whim of nature. The article paints heat pump and PV as a poor choice in this regard. Nothing could be further from the truth! We are constantly contacted by clients dissatisfied with the results of their solar pool heating system.
Valuable real estate
Your roof is valuable real estate, and the north facing section is ‘waterfront’. Why waste this valuable asset with a system that only provides six months’ use, and only provides one output? Solar PV will provide electricity. Everything in a house runs on electricity.
Solar thermal on roof vs heat pump
The installation of a heat pump is simple, cheap and no-risk. Solar thermal is expensive and risky to install, and can lead to issues in the future with leaking pool water on roofs. We’ve all heard of those horror stories of solar thermal and how much cockatoos love them. Even without the birds the systems deteriorate in the sun and leak, destroying gutters, downpipes and potentially poisoning soil with salt and chlorine. I’m yet to hear of a heat pump leaking pool water onto a roof and causing such damage.
Flexibility and customer satisfaction
Want a swim before work at 5 AM? Better hope you have overheated the pool the day before with solar thermal. A heat pump can, if required (and outside of the example shown above), run at any time of the day to ensure desired swim temp is achieved. Running for longer periods will also provide a longer swimming season if the heat pump is sized correctly.
In short, a client’s expectations for use of their pool can be met 100% of the time with a heat pump and cannot be guaranteed with solar thermal. Pool too hot in summer? (Yes, it can be an issue!) Simply turn your heat pump to cooling and use the solar PV to run the system as with the heating scenario.
These flexible options may not maximise the efficiency of the system, but they do maximise the opportunity for the client to use their pool, which is a significant investment in money, water and energy.
In short the data clearly shows that heat pumps are not the bad guy made out in the article, and combined with a very small PV system can provide a vastly superior result to solar thermal. There is no case that a solar thermal provider can make that I cannot provide a superior result with heat pump and solar PV. To ‘scare’ a customer into believing that they will pay $2000 to heat their pool with a heat pump is quite simply false and misleading.
The PV solar juggernaut is here to stay and heat pump technology is along for the ride…

If your pool is located indoors it could be costing you more than you think!
Dehumidifiers are designed to remove excess humidity from your indoor pool air and deliver ventilation to control pollutants caused from normal pool activity. There are many advantages of using swimming pool dehumidifiers such as having control over your indoor temperature and maintaining healthy and comfortable humidity levels.
If your indoor pool doesn’t have the correct ventilation or dehumidification it can lead to many issues such as:
- Corrosion damage to building components and fittings, in particular metal and concrete
- Reduced comfort levels due to high humidity
- Mould and musty odours
- Poor health due to high chemical concentration in the air
- High operating costs due to the need to supply fresh cold air into the room to combat the humidity and odours
Excessive humidity found in poorly ventilated pool rooms can form moisture and water making everything wet and humid. Not only does this make your pool room uncomfortable but it can also result in bacteria and fungus breeding causing health and wellbeing issues for anyone in your pool room.
Furthermore, this high moisture can cause corrosion damage to your house or building, practically any metallic and concrete surface within the facility which are costing to maintain or replace.
If you have an indoor pool you should talk to us at EvoHeat about our Solace Dehumidifier that is design to remove the moisture from your pool room without losing the warmth. The EvoHeat Solace is designed to be simple to install, operate and will maintain your indoor pool room comfort levels in rooms up to 300m³.
Pool too cold for your baby?
Swimming with your baby is a wonderful way to have fun with your family but did you know that adults and babies experience water temperatures differently? Although your pool water temperature may seem fine to you, your baby may be feeling very uncomfortable.
It is recommended that you take particular attention to children under the age of 2 years old as water temperatures that are too low or too high could be dangerous for your child.
The ideal pool water temperature for babies is between 31.5°C to 33°C. In Australia the average pool water temperature sits at around 18°C to 20°C, being far too cold to expose a baby to without pool heating.
It is important to know when your baby is too cold in your pool. If you observe your baby shivering or if it seems to be experiencing muscle cramps remove your baby from the water immediately and wrap it up warmly. Body temperature drops more quickly in water so it is important to notice these signs and act quickly to prevent hypothermia and other health issues.
• Check your swimming pool temperature before entering the pool – make sure it is between 31.5°C to 33°C
• Try and keep your babies shoulders under the water & moving about to keep your baby warm – exposure to the cold air may make your baby cold
• If your baby shivers or seems to be having muscle cramps remove your baby from the water immediately and wrap it up warmly
• When leaving the pool, promptly dry and dress your baby as the outside air may feel cooler
Better still, get an EvoHeat swimming pool heat pump installed so you can always ensure the perfect swimming conditions for your young family.
