1. Annual Efficiency
As a buyer of course you want to know how effective a heat pump is. There are different measurements of a heat pump’s efficiency. The most important is to rate the heat pump’s function over a complete calendar year-both the heat of the summer and the cold of the winter. This is called annual efficiency and shows the average relationship between consumed and supplies energy over a comparison period of one year. Presenting a heat pump’s efficiency at a particular measurement condition is not sufficient.
2. Hot water production
Hot water production makes up an ever increasing proportion of a home’s energy requirements and it is essential that the hot water is produced as effectively as possible and at the lowest possible cost. At the same time, fast water tank recharging is important to ensure hot water is always available. It is also extremely important that the heat pump has a system that minimises the risk of legionella bacteria
3. Comfort and Cooling
When investing in a heat pump it is essential to look at the needs of your home before choosing a model. Some heat pumps can both heat and cool your house, providing a good and comfortable indoor climate all year round. This should be done as effectively as possible, without unnecessary energy consumption.
