Electric heating with photovoltaic as an alternative?

The latest storage technologies make this an exciting prospect

It is the dream of all home and business owners: total independence from the energy supplier. Thanks to falling prices for photovoltaic installations, the latest developments in the storage market and energy-efficient construction methods, this scenario has become increasingly feasible. What’s more, the feed-in tariffs guaranteed for self-generated solar energy are falling all the time and are set to disappear in the not-too-distant future. These two factors, together with rising electricity prices, make the operation of your solar system particularly efficient if you consume the energy generated yourself.

Arguments for combined electric and photovoltaic heating

In the future, the insulation and energy efficiency ratings of a house will be crucial. So, too, will be running sufficient electrical appliances to consume the energy generated. As well as storage systems to recover the electricity when needed. In a private house, this would be in the evenings and in winter, at times when the sun isn’t shining.

 Technological developments are aimed precisely at achieving this: Passive or energy-efficient houses reduce overall energy needs, and mature and affordable storage systems are already capable of storing solar electricity generated during daylight hours. In addition, more consumer appliances can now be controlled digitally – even remotely via an app – so that they consume the electricity the moment it is generated.

This is where our electric radiant storage heating systems come into their own. Thanks to their refractory brick, they are particularly efficient and even heat up without electricity once they have reached the set temperature. The future generation will also be capable of storing the electricity generated during daylight hours and converting it into heat in the evening. And thanks to our control technology, you can also control all the radiators smartly, from any location.

 
  • The best possible options for storing the solar energy generated and keeping it available until needed.
  • Independent of the availability of fossil fuels, which are politically and naturally limited, and insulated from price increases
  • Passive and energy-efficient homes
  • The electricity generated by photovoltaic power creates no dirt or odours in the home, in the way fossil fuels do.
  • Self-generated electricity is clean and offers savings on your heating system

Numerous significant measures promoting energy self-sufficiency have already been introduced. But many are still under development. So it’s important to consider tomorrow’s possibilities when planning for today. Today, heating a building by means of an electric heating system and a photovoltaic installation is possible in principle, and is moving in the right direction. However, this only makes financial sense in certain situations.

  • A house with a surface area of approximately 100 m² and with average insulation requires approximately 6,500 kWh a year with our ComfortRapid electric radiators
  • A conventional 10 kWc photovoltaic installation is sufficient for this requirement.
  • For a 10 kWc solar installation, you need a roof surface of approximately 100 m²

  • The relatively high electricity costs are cushioned by the feed-in tariff, by the savings made on a standard system running on heating oil or gas and by the absence of maintenance costs, such as flue sweeping or wear parts in the heating system. In addition, optimal heating behaviour on the part of the consumer, together with a competitive electricity price or efficient insulation, can reduce costs even further.

A self-sufficient photovoltaic heating system, for example, consists of a combination of radiant storage heating and other innovative heating methods. We have a network of experts ready to plan your future with electric heat.

  • Solar cells can be found not only in conventional roof-mounted PV modules, but also on window glazing and in the masonry.
  • The prices of solar cells are falling all the time.
  • Passive and energy-efficient homes
  • Storage capabilities are constantly increasing, and their prices falling.
  • Electric heating systems are becoming more efficient and can now serve as storage systems.
