The hot water and heating circuit at the Rosenfelder Strand campsite is supplied by a central 6,600-liter hot water tank.
stratified storage is guaranteed. The main heat sources are a
Large-area solar collector system with four collectors of 17.5 m² net area each and a liquid gas condensing boiler cascade with 2 x 60 KW.
The buffer cylinder is charged by the solar thermal system via an external solar module, which stratifies the solar energy in the upper or middle area of the cylinder depending on the temperature. This allows the solar heat to be used effectively even at low temperatures.
Underfloor heating is connected on the consumer side, among other things. It requires a low flow temperature of around 30 °C, which is why it is integrated in the middle section of the cylinder. Three fresh water heaters from the VARIO fresh-nova system ensure the hot water supply using the continuous flow principle. The circulation return of the hot water supply can be switched over. In tap operation, the cold return water is stratified in the lower area of the cylinder; in pure circulation operation, the return flow takes place in the middle area of the cylinder, depending on the temperature.
