How much does it cost?

When thinking about central heating please ensure you are comparing apples with apples, not apples with oranges. Yes, air-to-air heat pumps are cheaper to install than central heating, but they only warm one room at a time. Central heating is a life changing experience that warms your entire home giving you the freedom to move around your home during the winter months as if it's summer.  Central heating transforms cold kiwi homes to provide happy, healthy comfort for you and your family.

*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 a single storey 240m2 (including garage) 4-bedroom home with two living areas heated to 21°C and two bedrooms heated to 18°C for 6-8 hours per day for a radiator system and 24 hours on low for underfloor heating.
