Operating principle
- The exchanger transfers the energy from the house's heating system to the pool water.
- Possible connection with all home heating systems (boiler, solar thermal panel, geothermal or aerothermal heat pump).
- If the primary heating circuit and filtration are far away, the heat exchanger must be placed near this primary circuit.
- Simple to use, it is only necessary to program the heater at 28ºC. The increase in temperature is reached within 2 to 5 days.
- To increase the temperature, place the filtration in continuous mode. Once the desired temperature is reached, reset the filtration to the automatic position.
