The panel heating and cooling systems are ideally suited for combination with renewable energies. Due to the large surfaces, the energy is given or absorbed into the room very evenly and thus provides a very pleasant room climate. In addition, the supply temperatures can be kept very low through the large surfaces. The flow temperatures are around 34 °C in the heating mode and around 16 °C in the cooling mode. These temperatures can be achieved easily using heat pumps, which operate with a very high efficiency. Moreover, the combination with solar thermal energy is perfectly possible.
Heat pumps are used to transport heat from one medium to another. For example, heat can be withdrawn from the ground to heat a building. This type of heat pump is called water-to-water heat pump.
Water-to-water heat pumps can also be performed reversibly. In doing so, in the winter heat from the ground is extracted and carried into the building and in the summer the heat from the building is passed into the soil. There it is stored to be used again for heating in winter.

For the generation of process water or for heating, solar power is a useful sustainable energy source which can cover up to 80% of domestic energy needs.

The power requirement of a heat pump can be covered by photovoltaic system. The electricity being generated is counted on an electricity meter and can be sold to the energy utility. On a separate meter the power can be bought back cheaply from the energy supplier. This has the advantage that one can fully benefit from the related law regulating the feeding of energy into the public grid and the energy subsidies for heat pumps. In addition, no elaborate electricity storage facilities are necessary – this system operates largely maintenance free.
The electricity is to be transformed from direct current into alternating current with an inverter and fed into the electricity grid. Occasionally, an exclusive energy supply by means of photovoltaics is realized in off-grid systems. Due to the high feed-in tariff for solar power, this variant only makes sense if no public power grid is available. In order to provide continuous energy, the energy has to be accumulated.
Heating systems can be combined with fireplaces. For this purpose, a double-walled fireplace is connected by pipes with a buffer storage tank. In the void between outer jacket and combustion chamber, water is heated with a circulating pump and transported to the storage. In so doing, the buffer storage is heated by the fireplace. This fireplace looks like any normal fireplace, but by emitting only 10% of the heat output into the room and 90% into the storage. Both the entire house as well as the drinking water can be heated via the storage.
When the fireplace is not in use, the heat pump or the conventional heating system is put into operation if the temperature falls below the programmed minimum temperature. We would be delighted to provide you some further information!
Water-filled fireplaces give off heat energy not only into the room but also via an integrated heat exchanger to the heating system. As a result, both the supply with heat energy and the generation of hot water is possible.
