Space heating from photovoltaics

Solar energy, and thus also electricity from your own photovoltaic system, is available in abundance during the day. In the evening or in winter, when more electricity is needed, the sun is gone. This means: storage is the central point with regard to renewable energies. As a rule, one third of the self-generated energy is used and two thirds of it is fed back into the grid. The payments for this have generally been falling for years. On the other hand, those for fossil fuels such as gas and oil are rising, and the general cost of electricity is also steadily increasing. On the other hand, photovoltaics are becoming cheaper and more effective - more surplus electricity is being generated. Our goal must therefore be to use more photovoltaic electricity for our own consumption.

How about an electric heating system using electricity from the photovoltaic system?

In order to do so, you need to know that in our latitudes, photovoltaics can also supply appreciable energy in winter. Especially because electric heaters have the reputation of being very expensive to operate, self-produced photovoltaic electricity is an exciting alternative. With our innovative products, you can finally keep the energy in the house to use it for something useful like heating. Of course, you don't have to do without supplying both your electricity needs and hot water via the photovoltaic system.

Electric heating with electricity from the photovoltaic system saves enormous investment costs! The operating costs are also reduced by up to 30 % compared to conventional heating systems. However, this requires a well-insulated building. Nowadays, however, this is usually self-explanatory in new buildings and renovations.

Compared to photovoltaics, a heat pump can "only" generate heat. It does not make any contribution to the electrical consumers in the building. In contrast, photovoltaics supply the normal electrical household consumers primarily before heat generation and thus contribute to reducing operating costs to the greatest extent possible. The remaining energy required for heating is drawn from the public electricity grid. The exact amount hereby depends on the insulation of your living space and the dimensioning of your photovoltaic system.

The prerequisite for heating with photovoltaics is a well-insulated building and a powerful photovoltaic system. Ideally, all suitable roof surfaces are used completely for electricity generation. If the heating requirement per square metre and year is less than 50 kWh, space heating can be covered sensibly and efficiently with photovoltaics.

Good to know: Our system can also be used to support an existing water-based room heating system. The heating element is then either installed in the combination or buffer storage tank, or two heating elements (hot water storage tank, heating buffer) are connected.

Depending on how much sun is available, the energy is stored in the hot water and in the heating. This all works in a stepless and precisely metered manner. This makes an electric heating system suitable for photovoltaics, this way it gets "PV-ready"!

Our principle of heating with photovoltaics works reliably and without line losses. In the long term, this is the best solution for low-energy houses. Electricity from your photovoltaic system provides a comfortable room temperature simply and directly.

You reduce the technical effort for heat generation to an absolute minimum and operate a system that does not require extensive service and maintenance. Unlike heat pumps, you have a silent, more or less invisible system.

We have been facing enormous price increases of gas and oil for a long time. At the same time, the costs of solar power are falling and photovoltaics are becoming more and more efficient. Seen in this light, generating space heating with photovoltaics is more economical in the long term than operating a gas or oil heating system. Basically, every kilowatt hour that is powered by solar electricity instead of grid electricity counts. This protects the environment and the climate and reduces heating costs. Do you ask yourself:

What points speak in favour of generating heat with your own solar power from the photovoltaic system? Heating with photovoltaics means 30 % lower operating costs and up to 30 % lower investment costs compared to conventional heating systems (e.g. air heat pumps). Maintenance costs are zero. They generate the energy themselves, consume it efficiently and sensibly directly on site, and can store it.

With a water-guided heating system, the primary heating system should be switched off during high-yield photovoltaic months - this protects the heating system, saves operating costs and extends the service life of your heating system.
