Hydronic Combination

Domestic Hot Water Connected to the Hydronic Heat Source

An enclosed copper coil or heat exchanger (connected to the heat source) heats the domestic hot water in the tank, keeping the hydronic heating water separate from the domestic hot water. The sensor pocket connected to the heat source is located in the middle of the tank; this means that the heat source won’t service the hot water until half of the hot water in the tank is used. Having the sensor in the middle stops the heat source from turning on and off every time a hot tap is turned on. Most heat sources are capable of heating the entire 400 L from top to bottom in about 30 to 60 minutes. The tank also has an electric element in the bottom of the tank as a backup mechanism.
