Electric heating - does that also save energy?

In many households, heating with electricity would be quite appropriate, instead of installing a central heating system. In terms of cost and power consumption, however, heating must be energy-efficient in any case. If and how this works, read here.

Heating with electricity: several possibilities

In addition to the well-known radiators and electric ovens, there are other ways to heat with electricity. One of them is also the night storage heating, which disappears in the last years because of their inefficiency more and more from the market, and therefore already in some areas is already forbidden by law.

Another way to turn electricity into heat is heat pump technology. On the whole, it is considered a fairly "green" form of heating.

The energy consumption here depends primarily on the efficiency of the heat pump, which is specified by the so-called annual working load (JAZ). The higher the JAZ, the more efficient and energy-saving the heat pump is.

A third option is the radiant heaters or infrared heaters that have only been on the market for several years. They work according to a completely different heating principle - not convection, but radiation.

Due to the fact that they can be switched on and off very flexibly, and in most cases do not have to run constantly, the energy consumption here is almost always very low. Overall, with their advantages they are the best way to heat with electricity.

Energy consumption in power heating

Classic power heaters consume comparatively the most. In view of the high electricity costs and the use of expensive daytime electricity, they are the least suitable form of heating.

Night storage heaters, such as those still present in some homes today, are also critical to power consumption. The problem here is rather the inefficiency and the high memory losses. But at least the - usually much cheaper - night stream is used for heating.

With heat pumps, the efficiency of the heat pump and the medium used - either air, groundwater or soil - are decoupled by energy efficiency. In comparison to the two previously mentioned types of heating, however, heat pumps are a real asset.

In the infrared heater, it is particularly important to professional installation, in addition to the duration they run per hour. This can be set flexibly via a timer. However, under optimal conditions, this form of heating is significantly cheaper than all the above, and offers other benefits as well.

Use only high-quality infrared heaters - that should in any case be so-called black spots. And leave the planning to an experienced professional.
