Boiler with 12 V Inline Pump(3020-9051)

The Alde 3020 Compact high efficiency combi boiler is ideal for central heating systems in boats, motorhomes, caravans and portable cabins. It provides 8.7 kW of heat through up to 14 m of aluminium convector with 93% SEDBUK-based efficiency. The boiler gives you luxurious heating that is clean and economical, with unrivalled silent, high performance, reliability, and comfort. Powered by LPG and/or 230 V electricity.

All system connections are on one side, allowing the unit to be installed in the smallest of spaces, and the flexible flue means you can position the boiler and terminal where you want. Once it's in the boiler has no service requirement, though the antifreeze product used should be changed according to the installer's schedule. For motor vehicles, why not invest in the additional engine heat exchanger, so you can transfer engine heat into your central heating system while on the move, making use of all that free energy!

All boilers are pre-fitted with flow assembly (automatic air bleed valve and non-return valve) and red and blue water connectors. The Alde 3020 Compact HE combi boiler comes with a 12 V inline circulation pump, for improved all-round performance, and the optional installation kit containing: 12 V lead, control panel and cable (9 m), side or roof flue terminal, exhaust and air intake hoses and clips, expansion tank and cover, non-return valve, and safety drain valve, red and blue water pipe, rubber elbow, and 12–15 mm Speedfit connector.
