Alde central heating boiler
Alde 3020HE hydronic boiler. Highly efficient Propane and 120V electric boiler
Perfect for your radiant floors, radiators, engine heat integration, and hot water.
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.
