Air Source Hydronic Heat Pumps

All hydronic heating and cooling systems need a power source, and heat pumps have become increasingly popular due to their many benefits, including greater energy efficiency and lower long term costs. 

Indoor renewable Stiebel air source heat pump

Relying on the air outside to heat and cool a property, heat pumps are one of the most energy-efficient choices for your hydronic cooling and heating systems. Heat pumps, have the ability to combine the heating and cooling needs of your home into one simple device.

Outdoor air is supplied to the air source heat pump – installed either indoors or outdoors – via flexible hoses and a quiet fan. A heat exchanger extracts the latent energy from the air which is converted by the heat pump into useful heat for your home. Even at icy temperatures as low as –20 °C, the air source heat pump still operates efficiently and economically, all the while impressing with its outstanding COP. Very high flow temperatures can also still be achieved without backup from a booster heater.

Australian Hydronic Heating and Cooling, a division of AJ’s Plumbing Pty Ltd, work with suppliers such as Stiebel Eltron and Rinnai, companies which have become synonymous with high quality space heating, water heating and renewable energy products. Below are details of a range of their air source hydronic heat pumps which Australian Hydronic Heating and Cooling can source, install and maintain for your property.
