What is Alde?

Innovators and makers of hydronic heating systems for campers, RVs and boats. We’ve been delivering the quietest, most comfortable mobile heating since 1949.

The intelligent inventor

Alde Rask, who founded the company in 1949, was an ingenious inventor, and it is in his spirit that we continue to come up with innovations and technical developments with a focus on comfort in campers, RVs and boats. Our affirmed strategy is to continue to be the world leader in our field. Therefore we reflect constantly on how we can develop ever better functions, product life and service, and we work non-stop to achieve these goals. 

Quiet, invisible, pleasant comfort are the things we work with. . .every day.

Cozy, silent heating

Nothing can compete with hydronic heating. Silent, even-temperature, all-round heating. 

Hydronic heating that is always there, providing discreet, unobtrusive, quality heating. 

Not only does hydronic heating provide cozy, silent heat, it also means healthy, dust-free air with natural humidity.

Reliable heat

Alde heating systems are probably the most reliable money can buy. 

Trouble-free heating and hot water, year-in, year-out. How do we do it? 

It's probably something to do with our origins. Scandinavia is cold and has a tough climate. So we have to be sure that we have reliable products that function faultlessly in all weathers. We have carried out tests to ensure quality and enduring effectiveness ever since 1966 when our first furnace saw the light of day. 

A warm, welcoming company

We are proud to be the world leaders in our field. Be we are all the more proud when our customers perceive us to be warm and welcoming when they contact us. We are happy to listen to their experiences, suggestions and points of view, all of which help us make improvements. Building strong, lasting relationships with our customers is very important to us. Together with our extensive service and dealer network throughout Europe, we are always ready to provide assistance.

Nothing can compete with hydronic heating

Hydronic heating provides silent, even-temperature, all-round heating. Natural, slow air currents provide healthy air with natural humidity. Hydronic heating provides discreet, unobtrusive, quality heating. Not only does the furnace provide cozy, silent heating, it also provides a constant source of hot water for the shower and galley.

Alde central heating is a hydronic system that works on the same principles as those found in many of our homes. The heat source consists of a propane furnace with a 230 Volt electric element that heats a mixture of water and glycol. The hot glycol mixture is circulated through the system's convectors and pipes with the aid of a pump.

The convectors, which are located along the outer walls, heat the air. The air then rises and heats the walls and furniture. Because heat rises, a boundary air seal forms in front of the windows, which keeps the cold out. When the warm air reaches the ceiling it circulates down to the floor and is heated again by the convectors.

Every vehicle needs ventilation, i.e. stale air must be expelled and fresh air drawn in. The fresh air supplied to the vehicle should be led through an insulated air intake and then up through a convector with tightly packed fins. In this way the incoming fresh air is heated when the heating system is running. The stale air is led out through roof grilles and ventilators.

If the installation is done properly, the natural flow of heat from the Alde central heating system will wrap the entire living space in cozy warmth that keeps out drafts, eliminates cold zones and even warms bunk spaces and cupboards.

We also recommend floor heating to achieve a complete heating system with maximum comfort. The heating pipes under the floor are connected together using standard fittings and are controlled either manually or via a by-pass assembly for convenience.

Alde Compact 3010. An ingenious furnace

Thanks to its ingenious design we've succeeded in fitting both the heating system and domestic hot water heating in this extremely compact furnace.
