If you have been inspired by our Mitsubishi heat pump price versus savings blog then you might now be wondering how many heat pumps you need for your Auckland home. Well, we are always on hand to help you with information so let’s answer that for you as efficiently as a Mitsubishi!
It is easier to calculate the heat pump needs for a new house because the insulation requirements are stricter and the insulation materials and methodologies are superior. The heat loss level can be accurately projected and, therefore, the heat pump specifications as well.
The calculations become a little trickier with older properties as heat loss areas are difficult to predict. In addition, when there is no insulation in walls and ceilings, as well as no double glazing, heat will be seeping out at a fast rate.
In addition to the age of the building, the following factors also need to be considered:
A living room usually requires a warmer temperature than a bedroom or bathroom. Adding up the heat requirements of each room will inform you of the overall heat demand and the Mitsubishi heat pump size.
The most commonly sold heat pumps sized sold in countries around the world are 4kW, 5kW, 6kW, 8kW, 10kW and 12kW. There are larger sizes available.
The type of heat pump you choose also influences the size of pump that you will purchase e.g. ground source versus air source.
If you have a 100 sqm size space you want to heat, you might consider starting at a pump size of 4 kW for a ground source heat pump and 8 kW for a 200 sqm (subject to the above factors).
Note: the energy consumption of a heat pump is significantly influenced by the ambient temperature. A ground source heat pump installed 1 metre below ground will have more consistent temperatures.
An Air Source Heat Pump’s energy consumption will fluctuate with the varying surrounding air temperature, especially if the machine is in an exposed location.
You can set a variable speed compressor to operate faster during colder temperatures to reduce power loss. Larger size air source heat pumps are usually compared to ground source units e.g. 5 kW versus 4 kW.
Subject to the factors listed earlier, you could use a 5 kW air source heat pump for every 100 sqm, 10 kW for 200 sqm, etc.
If you give us an indication of the square metres of each space or room and the temperatures you want to achieve in different seasons, we can guide you to the best choice. Every property is different and each lifestyle is as well. We’ll help you choose the best deal with the best return on investment that meets your heating and cooling needs.
