DC stands for double circuit heating. The two heating circuits work at the same time but provide different outputs at different temperatures. The two heating circuits are ideal for a combination of underfloor heating and radiators or underfloor heating and towel rails. The two circuits can also accommodate any other combination of heating circuits. The DC boiler also has connections for one of our external hot water tanks.

The DC boiler is fully equipped with all the hydraulics and controls in order to be connected to two independent heating circuits and one hot water circuit. The boiler is equipped with a special hydraulic mixing valve and second pump for heating circuit 2. Each circuit is complete with non-return valves, a flow sensor is fitted on the second circuit, and a 60°C built in safety thermostat to protect the underfloor heating is also fitted. All the electrical components are pre-wired in the boiler.

The DC boiler has many advantages, it is compact: it has the same dimensions as the THl 5-25 C. The installation is simple and quick. We consider that the installer can save up to 8 hours of installation time. The heat losses are lower, due to the fact that second heating circuit is integrated in the boiler. Installation errors are also reduced due to the pre-fabrication of circuits and controls.

Octagon Homes, the prestigious home developer, continue to use this unique appliance for many of their homes. The technology saves valuable space and simplifies the specification process.
