Descaler and inhibitors in central heating systems

Radiators in houses are sized to meet their heat loss. If however the water in the central heating system is not maintained at its neutral level (pH 7.0) then a chemical reaction will occur between the water and the steel pipework and radiators resulting in the build up of corrosion products. These products comprise gases which congregate in the top of radiators so limiting the heat transfer area and the build up of inorganic salts on the internal walls of radiators so limiting their ability to transfer heat.

Sachet containing 250cc inhibitor to reduce corrosion in central heating systems

Sachet

Both these factors can be minimised by adding a suitable inhibitor each year to the central heating system when it is serviced. Typically 250 cc have to be added annually and energy savings can be up to 10% with a similar reduction in carbon emissions
