In the winter, a heat pump works by extracting heat from the outside air (even when it is cold outside) and moving it into your home. In the summer, the process is reversed and a heat pump acts as an air conditioner (AC). The heat pump now draws heat from the air inside your home and transfers it outside.
The split system heat pump has two major components: the condenser (located outside) that circulates refrigerant through the system and an air handler (indoor unit) that distributes the conditioned air.
Heat pumps are widely considered the most economical form of heating large spaces or rooms such as lounges and living areas.
Heat Pump and Air Conditioning FAQs
What heat pump works the best?
Heat pumps come in a variety of models and sizes. When deciding what heat pump to buy it is important to think about the location and the size of the area you are wanting to heat or cool.
Depending on the layout of your room you may be happy to have a heat pump sitting on your wall, or you may chose a more discrete option and go for a floor console, or a ceiling cassette.
You may also want to consider getting a heat pump with a star rating for further peace of mind you’re keeping your energy bills as low as you can.
What size heat pump do I need?
Getting the right size heat pump for the area you are wishing to heat or cool is the most important factor on its ability to work and the energy it consumes.
For a rough guide:
1)room volume x 50 for a house with sufficient insulation
2) room volume x 60 for a house without sufficient insulation
We strongly recommend booking a free home assessment and we can help you chose the right size unit for your home based on your homes thermal efficiency.
Where is the best place to put a heat pump?
Having your heat pump in the right location can make a big difference on the efficiency of the heat pump and also the cost of the installation.
The first consideration is to make sure your heat pump can blow the air around the room unobstructed.
Secondly all heat pumps need to link between the indoor and outdoor unit. Placing a heat pump on an external wall so we can run the piping directly to the external unit is ideal and will lower the install costs. Placing the unit on an internal wall may require a gravity pump and additional piping.
Our install price includes up to 5 metres of piping.
Will a heat pump save me money?
Most heat pumps have a COP rating of between 3 and 4.5. This means for one kilowatt of power used it will provide between 3 and 4.5 kilowatts of heat. The higher the COP the higher the efficiency of the unit.
In comparison most other conventional heaters have a COP rating of 1 or less, meaning for 1 kilowatt of power they will provide less than 1 kilowatt of heat.
While heat pumps are much more efficient, we still recommend turning heat pumps off when no-one is home to save power. All our heat pumps have 7 day timers so can be set to warm the house before you wake each morning or before you get home in the evening.
