• : At the lowest setting (850–900 W), it runs with minimum noise—ideal for night-time use.
• : Low fuel and electricity consumption makes long periods of operation practical without sacrificing comfort.
• : Programmable, caravan-safe heating that operates independently of the engine, perfect for road and marine use.

What it does and how it works

When you power up the D2, the control unit runs a safety check, then starts the burner. Fuel is precisely metered and ignited in the combustion chamber, transferring heat to the air via a compact heat exchanger. A fan then draws room or fresh air through the exchanger, delivering warm air into the interior. The result is efficient, steady heat that keeps your living space comfortable no matter the weather outside.
