How much does it cost?

“How much?” is often the first question we get asked and it’s the most difficult question to answer as every home is different with unique heating requirements.
Our engineers, who have designed residential installations for over 10 years, got together to create our online calculator. They used data from 6,000 projects to determine the estimated cost of a central heating installation for your home.

*All costs include GST. All running costs take into account the thermal efficiency of the relevant heat source as independently measured by laboratory testing. Underfloor heating tends to use  more energy than radiators due to longer running periods.  Fuel used is based on heating living spaces to 21°C and bedrooms to 18°C for 6-8 hours per day for a radiator system and 24 hours on low for underfloor heating.
