An essential criterion in selecting the heating system concept for the client was the ability to reduce the consumption of expensive natural gas and maximize the energy efficiency of the system by having four different heat and cold consumers in the house.

The combination of a condensing gas boiler and an air-to-water heat pump made it possible to heat the house, heat hot water, heat the pool in the summer, and air condition the house in the summer.

The underfloor heating system perfectly combines the heat pump operation as a low-temperature heat source. Water channel fan coils provide air conditioning and maintain their temperature control in every room of the house.
