How it works

Nothing beats 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.

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.


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.
