Heating and hot water requirement

What is the energy requirement of the house How many occupants does the house have?

Are there any teenagers who use a lot of hot water or older people who want a hotter indoor temperature? It is important to match the size of the heat pump to the needs of the house.

There are heat pumps that have been specially developed to produce large amounts of hot water.

How hot should the water produced by a heat pump produces be?

55–60 °C is sufficient. Certain manufacturers allow their heat pumps to produce 65 degree hot water. The price for this is that the efficiency is reduced by approx 10 percent. In addition, a heat pump that does not produce unnecessarily hot water will have a longer service life.

An interesting question is how many people actually need water that hot. The risk of scalding increases and in most cases 55–60 ?C is more than hot enough. Instead of producing unnecessarily hot water, a good technical solution is to create such large hot water production that one can take a shower without the hot water running out. At the lowest possible
cost.
