Air to Water Heat Pumps

One of the most popular heat pump types on the market, Unitherm has a wide and diverse range of Air to Water Heat Pumps to suit every need. Our design team have pioneered a complete system solution from conception to commissioning, working closely with engineers, architects and installers. With each project we size the correct heat pump for the dwelling. This ensures the heat load is covered whether the dwelling in a well insulated new build or a retrofit.

These are heat pumps that provide heating by moving thermal energy from outside air to the inside air. Outdoor air is a universal heat source and sink medium for heat pumps and is widely utilised in residential systems. Older gas and oil-fired boilers waste energy and are costly to run, because of the amount of fuel they need to maintain comfort levels and hot water.Reduce your energy usage and greenhouse gas emissions with a Unitherm supplied heat pump today.

With innovation and safety in mind, the LG Therma V Hydrosplit separates the Indoor unit (IDU) and outdoor unit (ODU), connecting them through water pipes. The unit’s heat exchanger is located within the ODU, reducing the risk of indoor refrigerant leakage. Quick and easy installation is made possible by the IDU’s built-in hydronic components such as water pump, expansion tank, and air vent as well as the fact that the electric wiring can be done in the same space as the IDU.
