Here the pipework feeding the matrix of the blower unit has been tapped into the heating circuit, the first radiator on the loop is just out of shot to the right, this is all tucked away under the bed in one of the cabins. The pipestat is attached to the flow from the boiler, this will switch on the blower once hot water starts flowing through the system. Isolation valves have been fitted to make the inevitable maintenance of the matrix unit easier, as the system is pressurised to 14PSI, dropping the pressure out of the system without making quite a mess is difficult.

The heater itself is mounted on the other side of a wooden partition in the small space left under a shelf. This made installing the unit like trying to plumb in a radiator through a letterbox ;). 4 60mm ducts snake off to the vents mounted in the wall.

The hot water hoses appear through a hole in the timber to connect to the matrix unit, with some 15mm pipe in between as reducers from the 3/4″ hose to the 1/2″ attached to the matrix itself. The blower is wired in low speed mode only, as running it any faster makes far too much noise from the vents.

As a heating solution, this unit works well onboard. Within a 10 minutes of the diesel heater firing up, the blower automatically comes on thanks to the thermostat, and blows plenty of hot air into the saloon to keep the cold at bay.
