Heat Pump Supply and Installation
For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.
Types of heat pump
- Single-split systems are the most common heat pumps in New Zealand – they are air-to-air, with one indoor unit connected to an outdoor unit. These systems are designed to heat just the room that they are installed in, not the whole house. While leaving internal doors open may allow some of the heated air to travel into other rooms, in most houses this does not work very well, particularly if there is a hallway in between, if there are high ceilings or if the house needs a lot of heating.
- Multi-split heat pumps are designed to heat multiple rooms – and consist of one outdoor unit serving multiple indoor units installed in different rooms of the house.
- Ducted heat pumps provide central heating – by blowing heated air through ducts into multiple rooms of a house. While some can only be controlled centrally, others allow you to choose which rooms or groups of rooms you want to be heated at any given time (zoning). For example, you may only want to have your bedrooms heated overnight.
Heat pumps are the most efficient way of using electricity to heat your home, but some are much more efficient than others. Look for the Energy Rating Label – the more stars, the more energy efficient.
What’s more, some heat pumps struggle to perform at cold outside temperatures just above freezing point. If you live in a cooler climate, ask your supplier if the heat pump you’re looking at performs well and efficiently at cooler temperatures, and get it sized for the room you want to heat.
