In accordance with today’s standards, the entire heating system of the building is made exceptionally comfortable by underfloor heating powered by a Cascade Heatstar 10 kW heat pump system using H tariff electricity. Additionally, inverter air conditioning units for heating and cooling have been installed in all rooms, ensuring cost-effective and uncompromised temperature control throughout the building, both in winter and summer. In the ground floor kitchen-living room, there is a Cascade Black Art 5.1 kW design split air conditioner, while on the upper floor, there are two Cascade Vision Nordic 2.6 kW split units and one Cascade 3.6 kW ceiling cassette unit. In the other part of the building, a 3.5 kW Cascade CEH console is installed on each level. The units can be operated with individual remote controls or through two mobile thermostats located in the building. The outdoor units are positioned on the left side of the building, behind the parking spaces. Their low noise output and proper placement ensure that they do not disturb the occupants of the house. The outdoor unit of the heat pump is protected by the house’s alarm system. The entire mechanical system, including the domestic hot water storage, is housed in the mechanical room located on the ground floor. Moreover, the building features hidden engineering throughout, with no wires or pipes disrupting the space.
