What makes the Alde system unique?

We’re proud to say, our Alde 3020 heating system is the lightest, most compact combi boiler in the world. We think that’s quite an achievement.

Boiler Alde Compact 3020

The boiler is the heart of the heating system. It produces heat for both central heating and hot water. Thanks to our ingenious and compact construction, the boiler takes up very little space.

The boiler is fuelled by LPG or electricity (120 V). It can also be fuelled by both at the same time when you need maximum power, e.g. when heating up a cold motorhome in the winter.

Digital control panel

If the boiler is the heart of the system, the digital control panel is the brain. The control panel has a user-friendly touch-screen menu with functions for outdoor temperature, night-time mode, timed starting, external starting, etc. This is where you set desired temperatures and energy sources, and connect and adjust the boiler’s extra functions.

Convectors and panel radiators

The convectors are located along the outer walls where they provide heat and surround the interior with a protective blanket of heat that prevents draughts. They can be supplied in various dimensions and designs.

The integrated convectors are often used in stowage spaces and stair risers. Flat panel radiators can be supplied for spaces where it is very difficult to fit normal convectors, e.g. in WCs and wardrobes.

Hot water

The Alde Compact 3010 boiler contains a hot water heater type that means there is always hot water for the shower and galley.

The boiler has a volume of more than 2,2 gallons, which gives 4 gallons of mixed shower water. In the summer, the boiler can be set to only produce hot water.

Underfloor heating

In order to have a complete heating system that offers maximum comfort we can wholly recommend our underfloor heating. It consists of pipe loops in the floor that are connected to the normal heating system.

Diffusion plates spread the heat evenly across the whole floor.

Heat exchanger

With a heat exchanger installed in our hydronic central heating system, the vehicle engine's cooling system can be exploited for heating and hot water. The heat can also be run in the opposite direction using a circulation pump on the engine side, so acting as an engine heater.

Fan-driven heat booster

The heat booster is used for rapid and direct heating in the driver's cabin, or in wardrobes to dry wet clothes and shoes, for example.

It can be supplied in various versions. The most powerful model is a compact convector package with an efficient rear-mounted fan.

The small model consists of a specially designed convector with a row of small fans connected in series. In order to improve your motorhome's comfort further, the fan-driven convector can be fitted in the floor behind the seats.

The upward-driven hot air then creates a heat barrier between the living space and the driver's cabin. Saves energy and increases comfort!

Heated towel rail

The heated towel rail is a traditional design for the practical hanging of towels.

There are also models that offer individual temperature regulation.

Frost protection

Frost protection is a drainage/safety valve that automatically empties the hot water when there is a risk of frost (around +38 °F).

Also acts as a safety valve against excess water pressure, and as a manual drainage valve.

Driver’s comfort

To achieve comfort in and around the driver and passenger seats, there are purpose-designed convectors that can be fitted to Alde’s heating system.

Other alternatives are heating boosters or fan-driven convectors.

Tank heating

Alde’s tank heating protects your water and sewage tanks against frost damage. There are several alternative installations. Some involve convectors fitted between the tanks, some a pipe loop under the tanks.

These are then connected to the ordinary heating system.
