Revolutionary heat pump technology

Heat pumps offer heating, hot water and cooling. The main energy supply for a heat pump is from an environmental source i.e. air, ground and water – electricity is also needed in order to operate.

Vaillant offers suitable heat pumps for every energy source. Air-to-water heat pumps are an ideal option for an upgrade of your appliance. These heat pumps can be easily mounted outdoors and are low in acquisition costs.

Advantages of choosing a heat pump

Heat pump in a detached house

The Smith family have decided to move to a house which was built in 1997 which still has the same heating system installed since it was built. The heating system that was in use was an oil-fired boiler with a high energy consumption.

The planned upgrade of the heating system for the house should offer better comfort and also better energy efficiency.

The house has sufficient thermal insulation as well as an underfloor heating system: ideal prerequisite for the use of a heat pump.

Air source energy

  • The Smith family’s architect has recommended they install the air-to-water heat pump the aroTHERM split. This heat pump extracts thermal energy from the outside air and converts this into heating and hot water.
  • Mrs. Smith is pleased that the aroTHERM split is extremely quiet and thus, can be placed in the garden or near the wall of the house without any problems from the noise. The compact indoor unit of the heat pump is placed next to the washing machine in the laundry room. The heat pump is combined with the hot water cylinder uniSTOR that offers a capacity of 300 litres.
  • The system controller VRC 700 is used to operate the heat pump. It adapts the heating output automatically to the weather conditions, improving the energy efficiency.
