CalChem from CalMag is a three in one chemical inhibitor designed to protect central heating systems. CalChem combines a number of traditional products into one simple solution.

CalChem has a special advanced formula which begins to work upon contact with sludge, limescale, flux and other debris. The fast reacting liquid is water soluble, non-flammable and, more critically, non-acidic. This means it can be used on all types of heating systems including copper and aluminium. More importantly, CalChem is environmentally friendly.

CalChem should be added to your heating system via the filling loop or radiator. It will then break down silt, lubricate valves and pumps, suppress bacteria growth and eliminate the production of gases. CalChem also contains an anti-freeze solution which helps heating systems cope with cold weather.

The 1 litre CalChem is in stock now and is sufficient to treat 10 to 15 radiators. It is also available in 5 litre and 25 litre bottles. For the full specifications on CalChem please click here.
