Our "HWM"-concept water heater has a special ceramic duct system, which surrounds the water jacket on the outside while turning combustion heat into hot water and radiation at the same time. It is not only compact in its design- it is also more than efficient, due to the fact that its water boiler core is heated from all sides. You do not only have a constant water share, the total amount of available heat is also broken down in heat radiation. The maximum heating load is stated at 9kW and the approximate water boiler share is between 45-55%.
