How to size a heat pump

What does heat pump installation cost in Timaru?

The price table sets out typical New Zealand installed prices, including GST, for a standard back-to-back install, drawn from published price guides of eight installers and retailers. Back-to-back means the indoor and outdoor units sit close together on the same wall, with a short pipe run and a straightforward connection.

In a typical home, a small high-wall unit of about 2.5 kW suits a bedroom or small room, a medium unit of about 5 kW suits a lounge, and a large high-wall unit of about 8 kW suits open-plan living. A ducted system covers the whole house. The guide to heat pump sizing explains how to match a unit to a room.

The energy label shows heating output at 7°C and 2°C outside, and cooling at 35°C, so compare quotes on the same figures. Frosts can occur anywhere in New Zealand, and inland and southern towns see colder winters, so ask how a unit performs in the cold.
