Which ​swimming pool heat pump ​is right for my residential swimming pool?

The size of the swimming pool heat pump depends on various factors such as:

  • 1.Pool dimensions
  • 2.Swimming season (All year round or specific months of the year)
  • 3.Desired water temperature
  • 4.If the pool is covered when not in use
  • 5.Pool geographic location

Madimack has made it easy for anyone to get their hands on the optimum selection for their swimming pool heat pump. Introducing the online swimming pool heat pump calculator, a fully integrated online tool that can send you a full heating evaluation for your swimming pool in less than a minute!

Please follow the link below for your customised pool heating evaluation:

Madimack offers three different types of swimming pool heat pumps for residential facilities - Elite Silent as the premium model, Summer Eco as the cost-effective model, and Eclipse as the space-saving heating and cooling system.

Whatever heat pump model you get your hands on, rest assured that you own the latest inverter technology and a standard remote control through a Wi-Fi app on your phones or tablets.! Also, Our titanium heat exchanger comes with 25 years of warranty and our entire range of swimming pool heat pumps are capable of operating in temperatures as low as -10°C and as high as 43°C, with heating capacities ranging from 9kW up to 35 kW meeting requirements of all residential pools.

What is the warranty and performance guarantee on these pool heating ​heat pumps?

Inverter swimming pool heaters have an outstanding performance and warranty level compared to older technology. Madimack is the only heat pump manufacturer to offer a Performance Guarantee. 

All our heaters are tested by the industry-leading TuV Rheinland. A quality testing facility, known internationally.

Our performance guarantee means the kW we display is the kW you get. 

And with 25 years warranty on the titanium section of the pool heat pumps, you can be assured that the water chemistry does not affect it.

Why should I buy an ​electric pool heat pump​ when a gas heater is less expensive?

A gas heater's initial cost is indeed cheaper than an electric swimming pool heat pump, however, the running cost of gas heating systems is up to 5 times that of an electric heat pump. 

Our pool heat pumps will save you money in the long run. On top of that, a pool heat pump's lifespan is 3 times more than that of a gas heater. The maintenance costs are lower as well!

And, electric heat pumps can be powered by renewable energy systems including PV systems.

If I use salt in place of chlorine, will it damage the ​pool heat pump?

All Madimack pool heat pumps are equipped with a titanium heat exchanger, this allows the heat pump to heat any type of water such as chlorine, salt, and bromine which are the most common in the swimming pool industry. To give you an extra piece of mind, we offer 25 years of warranty on the titanium heat exchanger!

Where should I place my electric pool heat pump?

Electric pool heat pump units are weatherproof and are designed to go outdoors. They are built built with a marine grade aluminium alloy to withstand the harsh Australian weather conditions including heavy rain and wind. 

How long does the swimming pool heat pump ​run in a day?

The swimming pool heating system will run for different amounts of time depending upon the size of the pool and unit installed, the time of the year and the location.

On warm sunny days in summer, when the pool is up to room temperature, the heat pump may not need to run for more than 1-2 hours. But as the colder period starts to arrive it may need to run up to 8-10 hours.

A heat pump can run for up to 24 hours a day but we recommend not going above 16 hours as you should be able to get the required temperature within the 16 hours if the unit you installed is the right one for your specific pool conditions - Some days/ weeks may be excessively cold and may require more hours to run.

A Tip: Always oversize when purchasing a pool heater. An undersized pool heater takes longer to heat and cost more money to operate. 

Undersized heaters may have to run for 24 hours a day and may still not give you the desired temperature. So, please ensure you do a pool heating evaluation, which is free of charge and is automatically sent based on your pool conditions.

What does “3-Phase” and “Single-Phase” mean?

This is the type of electrical supply that the heat pump needs. Smaller swimming pool heat pumps that are used for the residential homes are normally single phase.

The Madimack Elite Heat Pump range is the highest single phase heat pump available in the market.

Larger pools, commercial pools or all-year-round swimming pool heating system units may be a 3-phase model.

What is a COP?

The COP is the Coefficient of Performance. COP is a ratio of energy input to output. For instance, a unit with a COP of 10 would use around 8kW of electricity and will provide 80kW of heat (i.e. 10*8=80kW)

Madimack heat pumps bring you the most efficient electric pool heater systems that come with an average C.O.P of 10 and in some circumstances up to 20. This means that for every unit of energy heater consumes, it produces 10 units worth of heat.

How long will an electric pool heater take to heat a swimming pool?

A heat pump can heat a pool even in temperatures as low as -15 degrees. Even though this is the case, a heat pump extracts the heat from the air so the warmer the air the more efficient the heater.

It may be more efficient to run the heat pump through the day time where the ambient air is warmer and more humid.

Do winters lower heat pump efficiency?

It does. Pool heating systems draw their heat from the air around them. The efficiency of the unit is reduced when the temperature is lower and there is less ambient heat available to draw from.

We consider this while designing our pool heating systems to bring you only the best pool heaters that maximize efficiency and deliver optimal results even in winters.
