Swimming pool heat pumps

We develop and manufacture heat pumps for family and hotel pools, whirlpools, cooling boxes for athletes and cooling pools for saunas. Our specialty is year-round heat pumps for indoor pools with a -15 °C function, as well as units for the tropical zone with an ambient air temperature of up to +60 °C. We can heat the water up to 45 °C and also cool it down to 5 °C. We offer all models in monobloc and split versions. We work with salt, chlorine or sulphur water.

Fish pond / Oyster heat pump

Delightful swimming

Pool temperature control whatever the weather is a key feature for regular or occasional swimmers.

If you require a specific pool water temperature to boost your performance as a professional swimmer; or if you wish for a warm bath for yourself or your small kids; or if you wish for a refreshing plunge in the summer, a reversible heat pump from Microwell ensures all of that. Using only electricity it can heat or cool your water as per your preference in a wide range from +5°C up to +45°C. No oil, gas or other fuel is needed. Microwell heat pump heats or cools the water, as per your desire, whatever the weather; during the day, during the night, during rainy or cloudy days.

Heating in winter

During colder months or nights, swimming pools continually lose heat through evaporation and convection; simply because energy is transferred from warmer object to a cooler one. Certain measures such as pool cover, shade or wind shield help but cannot eliminate the effect of water cooling. Heat loss must be actively compensated in order to maintain a desired, comfortable, water temperature. Microwell pool heat pumps can effectively heat the water.

Cooling in summer

During warmer months or sunny peak days, swimming pools are exposed to solar gain and convection heat gains since everything around them is warmer than water; simply because the energy is transferred from warmer object to a cooler one. If left untreated, pool water inside swimming pool will become uncomfortably hot which will prevent the user from having a pleasant bathing experience. Measures such as pool cover, shade or wind shield help but cannot eliminate the effect of undesired water temperature increase. Microwell pool heat pump can effectively cool the water and thus ensure delightful swimming.

Frequently searched phrases

Heat pump with titanium heat exchanger

The pool heat pump equipped with a titanium heat exchanger represents a significant advance in pool heating technology. The use of titanium in the heat exchanger increases the corrosion resistance of the system, making it particularly suitable for harsh pool environments. This not only extends the life of the heat pump, but also ensures efficient and consistent heating performance. The titanium heat exchanger in pool heat pumps is a testament to the industry's commitment to durability, energy efficiency and overall satisfaction for pool owners looking for reliable and sustainable solutions to heat their aquatic spaces.

Swimming pool heat pump with cooling

The pool heat pump with cooling option adds a versatile dimension to aquatic comfort. This modern system not only efficiently heats the pool water, but can also be reversed to provide cooling during the warmer seasons. Utilizing the same technology that heats the pool, the heat pump removes heat from the water and releases it into the surrounding air, effectively lowering the pool temperature. This dual functionality increases the usability of the pools and allows them to be used all year round by maintaining the optimum water temperature regardless of the outside climate.

Swimming pool heat pump for winter conditions

A pool heat pump designed for winter conditions works by using the ambient air temperature to efficiently heat the pool water even in colder weather. Unlike traditional heaters, these pumps use electricity to transfer heat from the ambient air to the pool water through a cooling cycle. The system remains effective even in winter, although its efficiency may decrease as the temperature drops. To increase performance, some models are equipped with features such as defrost cycles and advanced controls that ensure pool owners have comfortable water temperatures even during the colder months.

Split pool heat pump with wifi

The split pool heat pump with Wi-Fi integration embodies the modern convenience of temperature control in an aquatic environment. This innovative system allows users to remotely monitor and adjust pool temperature settings via a user-friendly Wi-Fi interface, providing unparalleled flexibility and ease of use. With the ability to optimise heating schedules and energy consumption from a smartphone or other connected devices, this technology not only improves the user experience, but also promotes energy efficiency by ensuring the pool is heated exactly when it is needed. This combination of split heat pump technology and Wi-Fi connectivity sets a new standard for intelligent and user-centric pool heating solutions.

Swimming pool heat pump for whirlpools and whirlpool baths

A heat pump for a hot tub or whirlpool pool is an important component that enhances the overall experience of these aquatic facilities. A heat pump that is specifically designed for these smaller bodies of water effectively regulates the temperature of the water, providing users with a pleasant and comfortable environment. This technology is not only energy efficient, but also extends the usability of the hot tub or whirlpool throughout the year, making it a valuable investment for both residential and commercial environments. The precise temperature control and reliability of pool heat pumps contribute to a luxurious and relaxing aquatic experience.
