How do you determine the heat requirement of a detached house?

Due to rising energy prices, the lowest possible heat demand in a single-family home is of great relevance. The following article explains why insulation is so important on this topic and how you can determine the heat demand of your home.

The insulation - the basis for efficiency

The determination of the heat demand

If you want to determine the energy requirements of your single-family home, the strength of the insulation is the first basis. The insulation is divided into four stages:

  • no insulation
  • partial insulation
  • thermal insulation according to the Thermal Insulation Ordinance 1995
  • Insulation according to the Energy Saving Ordinance (low-energy house)

You can usually easily assign your house: If none of these regulations complies, only the first two steps are possible, whereby "no insulation" is very rare these days, because here an immense heat requirement ensures horrendous operating costs.

If you have determined the possible thickness of the insulation, a second factor is added: The performance of your heating system. In kilowatt-hours (kWh), it should be as low as possible. While 8 - 10 kWh on 120 square meters is a good value, values ​​starting at 15 kWh are a problem.
You can usually find the electrical output of your heating system on a certificate on the boiler. Wirksam Effectively reducing the heat requirement

Now that you know the factors that determine the heat demand of your family home, namely insulation, heating and size (or volume), you can easily guess how to reduce your heat demand. In addition to the already mentioned insulation, it is of immense importance to use efficient heating.

It should be absolutely adapted to the size of your family home. Many homeowners make the mistake and buy too low a heater that can not meet the heat demand of the house. The result: If energy escapes (usually during ventilation), the room temperature recovery takes too long. The result of a too large heating is clear: The energy consumption is too high and exceeds the energy requirements of the family house.

Tips & TricksLet you determine the heat demand of your house professionally (for example, by the TÜV), before you decide for a new heating or insulation. The more customized the components are to your home, the higher the efficiency.
