Stiebel Eltron Air Source heat pump for Hydronic Heating

NewGen Solar & Heat Pumps can help you choose alternative means of keeping their homes warm over winter, hydronic heating systems have started to see huge popularity in the Australian market. The system warms using water heated up to 65 degrees; once the water reaches the desired temperature, it passes through pipes laid beneath the home’s floors and its heat radiates upwards into the rooms above.

To help your home produce hot water for the system in a way that is renewable, STIEBEL ELTRON supplies a range of air source heat pumps that utilise energy in the air to produce heat. If you aren’t sure which heat pump is best to meet your needs, our team at NewGen Solar & Heat Pumps is here to help. We can assist in the selection of a pump that suits the size of and number of occupants in your home.
