High-yield water heaters
Especially suited for the combination of heat pumps with solar systems with indirectly heated upright water heaters and a particularly large, welded-in tandem heating coil for supplementary heating and an additional straight-tube heat exchanger at the bottom for connecting a solar system. Inspection flange can be used for connecting additional heat sources (electric heating etc.). Robust and installation-friendly design. Can be combined with all modern heating systems. Equipped with a thermometer and thermowell for the temperature sensor. Optional foot height adjustment.
