Alde Compact 3020 HE

The heating system mobile living

The Alde Compact 3020 HE central heating and hot water boiler is the ideal choice for boat, motor home, caravan and portable accommodation applications. It offers a combined 8.5 kilowatt output giving plenty of hot water and is able to utilise up to 14 meters of Alde convector or six 1kW domestic panel radiators. The boiler automatically adjusts its power output to match demand to ensure maximum efficiency operating on either LPG or 230V.
All connections are located on the front of the boiler to allow a tidy installation that maximises usable space and location options. Side or roof flue terminals are available, linked to the boiler by a flexible flue which cools the exhausts gases giving further installation possibilities.
The glycol fluid is circulated silently around the heating system by the unique Alde 12V pump which works with the header tank to give a very low battery draw for extending trips away without electrical hook up. As the heated glycol solution passes through the system, the convectors give an even temperature throughout with minimum heat fluctuation, just like a modern central heating system found in a home.


Boiler design

The Alde Compact 3020 HE boiler has been designed to deliver reliable superior heating in the toughest Scandinavian conditions. Testing and monitoring of quality parts and materials is ongoing and rigorous.
The boiler consists of three eccen­trically-fitted cylinders (heat exchanger, water jacket for the heating system and, outermost, water jacket for hot water). The two outer pipes, and their ends and connections, are made of stainless steel, while the heat exchanger is made of aluminium. The heat exchanger is divided into two semi-circles. The burner is located in the upper half, being the combustion chamber, and the combustion gases are expelled through the lower half. The burner unit is fitted on the end of the heat exchanger. It consists of a combustion fan, burner, solenoid valve and intake/exhaust connections.
Two heating cartridges are fitted to the water jacket of the heating system.
