The WEBER HT 12 kW, 3-phase monobloc air-to-water heat pump from Sunex is manufactured with innovative and advanced EVI INVERTER technology, offering customers the benefits of highly efficient building heating, with both underfloor heating and radiators.

The WEBER HT monobloc heat pump for central heating and domestic hot water is efficient and extremely user-friendly. Another advantage is the cooling function, which, when used correctly, makes conventional air conditioning systems unnecessary.

The device was specially developed for the respective climate and is suitable even for the coldest regions of the country. This allows the heat pump to operate even at outdoor temperatures down to -25 °C. By matching the WEBER pump to the building's energy consumption, the use of additional heat sources is completely avoided or only occasionally required.

The 3-phase WEBER heat pump is manufactured according to the strictest quality control systems and with high-quality components such as a Panasonic compressor and a Carel controller. The refrigeration system of the device is equipped with EVI Inverter technology (additional vapor injection) (automatic adjustment of heating output to heat demand). This leads to a long service life and a high energy efficiency class of A+++.

The WLAN service module is also important as it enables quick service response without an on-site visit.

Principle of Operation of the Monobloc Heat Pump

The WEBER heat pump is designed as a monobloc. This means that all components except the control panel are housed in a single, compact casing that is mounted outdoors. This allows it to be used even in buildings with small boiler rooms. The principle of operation is similar to that of other refrigeration systems: heat from the outside air is transferred via a fan to the pump's evaporator. In the evaporator, a gaseous refrigerant absorbs the heat and is then compressed to a high temperature by a compressor. At this point, the heat is transferred to the circulating water via a plate heat exchanger, known as the condenser. The water is then routed indoors via pipes.
