Where does the air in my central heating system come from?

Water always contains air. The amount of air varies, depending on the pressure and temperature of the water. When the water is heated in a boiler, air is released in the form of micro-bubbles. Air in a central heating system leads to all sorts of annoying phenomena. For example, it causes swishing and banging noises in pipes and radiators. Air is also often the reason why a radiator does not heat up fully, or at all.

Why is it advisable to fit a air deaerator?

The SpiroVent RV2 removes the micro-bubbles from the hot water immediately after it leaves the boiler. Further along the system, the water can take up air again and will burst the air bubble. The radiators will then heat up evenly again and the boiler will run as efficiently as possible.

Where does the dirt in my central heating system come from?

The main cause of contamination is corrosion resulting from the reaction of (the air in) water with the parts of the system containing iron. Contamination in a central heating system consists mainly of harmful magnetite. A clear indication of the presence of magnetite is the installation water turning black. A build-up of magnetite deposits prevents optimal operation of the heating system and leads to excessive damage and breakdowns.

Why is it advisable to fit a dirt separator?

The annoying and sometimes costly consequences of contamination in the installation water can be avoided with a magnetic dirt separator. This dirt separator removes magnetite extra fast from the installation water. A system with clean water is far less sensitive to breakdowns and ensures that the boiler runs as economically as possible and that the pump uses as little electricity as possible. The magnetic dirt separator is advised by all well-known boiler manufacturers.
