Normatherm KKH20 / Passivhaus Boiler Stove
I just stumbled across some information about the Normatherm KKH20 Passivhaus Boiler Stove and am curious if anyone in here is personally familiar with them.
"The Normatherm KKH 20 stove which has a large square window in front of the fire, gives very little heat to the room at 1.9kW (6,483 Btu/h) and most of the heat to water at 17.3kW (59,030 Btu/h.) This means that you can run a Normatherm KKH 20 boiler stove in a low energy or Passvihaus and not totally overheat the room that the stove is in. Some small part of the heat may be needed for space heating for a few weeks of the year but most will be used for domestic hot water during the cooler months when the solar thermal input is that much lower. The Normatherm KKH 20 can be totally room sealed by connection to an external air duct and this air is thermostatically controlled to automatically regulate the output of the stove."
Any idea whether or not they're available anywhere in North America or have any intentions of being? It's intriguing technology for a Passivhaus and completely Green.
