How it works
There's nothing to beat hydronic heating
Hydronic heating is silent, consistent and all-enveloping. The slow, natural movements of the air result in air with natural humidity. Hydronic heat is just "there", without you noticing it. Real quality heat. Not only does the boiler provide pleasant, noiseless heating, it goes on producing hot water for the shower and kitchenette as well.
The Alde central heating system is a hydronic system, with the same heating principle as in most of our homes. The heat source comprises an LPG boiler with a 230-volt immersion heater, which heats a liquid mixture consisting of water and glycol. Hot glycol water circulates around the system through radiators and pipes by means of a pump.
The convectors that are placed along the outer walls heat the air. This then rises and heats the walls and furniture. Since hot air rises, an air barrier is formed in front of the windows, which keeps the chill off. When the warm air reaches the ceiling, it circulates down towards the floor and is reheated by the convectors.
Each vehicle must have ventilation, i.e. fresh air needs to be supplied and used air expelled. The supplied fresh air in the vehicle should be directed in through an insulated air intake and on up through a convector with closely spaced slats. In this way the incoming fresh air is heated when the heating system is operational. The used air is ventilated out through the roof panel and ventilators.
If the installation is correct, the natural flow of heat from the Alde central heating system means that the entire living space is wrapped in a comfortable environment, which shuts out draughts, eliminates cold spots and also heats both beds and cabinets.
Underfloor heating is also recommended to give a very complete heating system with maximum comfort. The heating pipes in the floor are connected up to a regular pipe system and controlled either manually or via a shunt package for easy control.
The warm convectors along the outer walls and pipe coils in the floor heat the air which in turn heats the furniture and walls.
Since hot air rises, an air barrier is formed in front of the windows, which keeps the chill off. When the air reaches the roof, it circulates towards the floor and is heated up again by the convectors.
