Article number: 40009091

The boiler Alde Compact 4000 D provides central heating and hot water. The heating system contains both a diesel burner and electrical elements, and can be powered with either separately or both together.

System description

The Alde Compact 4000 D operates in two power ranges (1–6 kW for diesel, 1–3 kW mains electric) for a combined 1–9 kW of heating and hot water. Heating is distributed via pipes, convectors and other heating accessories throughout the whole vehicle.

Heat convects upwards through air gaps, enveloping the interior in a gentle and unobtrusive warmth. Being a modular and adaptable system it is suitable for a huge range of vehicle types, from campervans to overlanders, to sports homes and luxury horseboxes. The Alde Compact 4000 D also continues Alde's commitment to supplying the UK inland waterways.

High output

Being able to combine two power sources, electrical and diesel, the Alde Compact 4000 D delivers an impressive total output of 9 kW. This dual-power capability ensures robust and reliable heating performance, making it suitable for a wide range of climates and conditions.

Advanced Dual-Zone Heating Option

Building on the success of our previous models, the Alde Compact 4000 D offers an advanced dual-zone heating option. This allows users to set and control temperatures in two distinct zones within their vehicle.

Premium Silent and Even Heat Distribution

The Alde Compact 4000 D continues our tradition of providing premium silent and even heat distribution. The smart Alde system, based on convection technology, ensures that every vehicle is heated quietly and eciently, creating a comfortable environment without noise or temperature fluctuations.
