  • What is a heat pump COP?

COP stands for coefficient of performance, it’s a measurement of efficiency for heating and cooling machines which is measured by the total energy output (kw) that is leaving the unit in forms of heating or cooling over the total energy input (kW) that is entering the unit in forms of electricity. The higher COP is the more efficient a unit is, we are proud to say that our units are remarkable for their high COPs of 8 to 10 on average.


  • How much warranty do I get with my purchased unit?

Summer Eco units will have 2 years’ warranty, while the Elite silent units will have 4 years.


  • What is the difference between an Elite & a Summer Eco unit?

Elite units come with 4 years warranty, while the Summer Eco comes with 2 years. In addition to that Elite units are more efficient and have more capacities than the summer Eco. Finally, the Elite unit is quitter and fits in your pool environment better than a summer Eco.


  • Why should I choose a Madimack unit for my pool heating needs?

Pool heat pump operation and understanding pool heat pumps
  • How does a pool heat pump work?

Heat pumps are basically a reversed cycle of an air conditioner, refrigerant R32 is the working fluid in our heat pumps, initially the fluid is liquid, refrigerant absorbs energy from the ambient air through the evaporator causing it to evaporate which leaves the R32 in the gas state. After that the gas refrigerant escapes to the compressor in which it’s heat and pressure are raised to the highest in it’s cycle, then it flows to the condenser, which operates as a heat exchanger, the heat of the refrigerant is exchanged with the low temperatures of the water in the pool system, causing the refrigerant to turn into liquid and heating the pool water. Finally, the liquid refrigerant goes back to the initial point which is the evaporator to repeat the cycle again for pool heating.        


  • What happens when the heat pump reaches the desired swimming temperature?

Heat pumps have built in thermostats that monitor the pool's temperature, when the swimming temperature is reached the heat pump is turned off automatically, it comes back in operation only if the pool temperature is dropped by 1 degrees less than the set temperature. All our heat pumps have the best of inverter technology which allows it to drop to a lower speed and higher efficiency. You may notice a reduction of the fan speed once the heat pump displays the set temperature this is how it maintains a perfect swimming temperature whilst your filtration pump is running.


  • What is the coldest temperature at which the heat pump can be operated?

our heat pumps can be operated in temperatures as low as -10 degrees Celsius.


  • What is defrosting option in our heat pumps?

Defrosting is a process used to protect the heat pump from frosting when the climate reaches very low temperatures, a reversible valve is installed in any unit that we have by default, this valve reverses the flow of the heated refrigerant at the compressor to flow back to the condenser to keep it from frosting, this is done automatically in case of any frostings started to form on the unit.


  • How fast can the pool be heated by the heat pump?

The time needed to heat a pool depends on how big the heat pump that you have is, the volume of the pool and the heat loss from the surface of the water in the location you are in.

Depending on the month of the year it is, the first time you switch on the heat pump you can expect a temperature rise of between 0.1 and 0.3 degrees per hour. This also depends on the heat pump installed as well. For a quick guide to calculate how many hours it will take to heat the pool is a calculation

(pool volume x temperature rise)/ 450

Then divide the answer by the kW of the heater and that is the approx. number of hours.

(Note this is just to heat up the water and doesn't take into consideration the heat loss during heat up and other environmental factors)

A heat pump is designed to maintain a pool temperature by running everyday. This ensure the water is always ready to swim in.

Note that a pool heat pump sized for Extended season only will not be able to achieve the set temperature in the winter months.

  • What is the life expectancy of a heat pumps?

With regular maintenance and servicing, our heat pumps should extend much further into the future than our warranties.

  • What type of water do i need to have in my pool to use a pool heat pump.

All our heat pumps come with the highest quality titanium finned heat exchangers, allowing you to use any type of water chemistry without worrying about the units lifetime.


  • Is it important to have a pool cover?

Having a pool cover will significantly reduce the size of the heat pump required for your pool, thus reducing the unit cost, that is due to its ability to save the heat supplied to the pool from being lost to the atmosphere.


  • How much space should I keep around my heat pump?

We have included details for minimum ventilation requirements for installations in the installation manual, click here for:

  • Can I use solar heating and my inverter heat pump simultaneously?

Yes that is possible however, this will probably not reduce the size of the heat pump significantly, this is because solar heating cannot be operated in certain climate conditions for instance if the weather is cloudy only the pool heat pump will be operating thus you need it’s full capacity to work.

Maintenance and troubleshooting
  • Why is water coming out of my heat pump?

It is very normal for water to come out of the bottom of the heat pump. This is usually caused by condensation forming because of the heat transfer. The easiest way to test that is to capture the condensed water and test it for chlorine or salt. If it is clear then it is very normal. The heat pump comes with a drain attachment and hose to remove the water to a drain.

If the water does have traces of chlorine or salt then there may be a leak on the water pipe, please fill out the form on this page and we will contact you with some further fault finding tips.

  • What does E3 and E6 mean on the heat pump's screen?


E3: is the no adequate water flow running through the heat pump, in this case check your filteration system and make sure that it's running, if it's already running then wait for a short period of time for the water to flow through the heat pump


E6: is excessive temperature difference in the heat pump's water inlet and outlet caused by the exe, make sure to backwash your system in regular bases to clean the filters, not doing so will cause this error in your heat pump.


  • What is the meaning of a certain error that is showing on a heat pump’s screen?

Find all the error codes and their references in the installation manual of any heat pump that you purchase (Find it in Eco Manual p. 18, and in Elite Manual p. 19) feel free to contact us for any assistance you need in maintenance and troubleshooting

  • My heat pump is operating but not heating, why?


Check the air temperature, a pool heat pump requires warm air to operate most effectively, however, in cooler temperatures, the heat pump runs longer to reach the designated water temperature.

Make sure your pool pump is providing the heat pump with a sufficient water flow. A heat pump needs a steady supply of water to properly handle heat transfer and production.

Clear any obstructions or debris from the vents. This ensures optimal air flow, which is essential to an air-source heat pump’s heating process.


Check the temperature of the thermostat, if the pool's temperature is already higher than the thermostat, the heater will not operate.

Wifi and app configuration
  • How do I connect my unit to Wi-Fi?

In our heat pump installation manual we have added a step by step procedure to connect the heat pump to Wi-Fi and configure it through our app. Check the instructions in the installation manual for our units below:

2- Summer Eco unit installation video guide. Click here


  • What are the uses of the mobile app?

Connecting your heat pump with the app will give you full access to the heat pumps controls wherever you are as long as you have Wi-Fi. You can turn the heat pump on/off, monitor the temperature of the pool and set timers for the heat pumps operation periods during the day. Note that the circulation pump should also be running for the heat pump to operate.
