Boiler for mobile leisure vehicles.

The boiler with built-in water heater is the heart of the Alde heating system. It is powered by environmentally friendly LPG and electricity. 
The complete system also includes convectors, underfloor heating and other accessories that together create a comfortable comfort.

We have bespoke models which are prefitted with e.g. water connections, automatic bleeding and a 12 volt circulation pump.


Boiler construction

The boiler’s internal heat exchanger consists of three concentric cylinders; the combustion chamber, the central heating cylinder and the hot water cylinder.

The combustion chamber is made from aluminium, and is divided into two halves by a baffle plate, with the burner head located in the top half, and the flue gases venting through the bottom half. The combustion assembly is fixed to the end of the internal heat exchanger. It consists of the burner, combustion fan, gas valve, air intake and exhaust ducts, and gas line.

Two electric heating elements are sealed inside the central heating cylinder, 1 kW each.

The room thermostat is integrated into the touchscreen control panel and connected to the boiler by a Registered Jack (RJ) cable.

Gas fittings are not included with the boiler.
