The problem...
Condensing boilers produce water vapour during combustion, the water vapour condenses and latent heat passes into the system. Acidic water known as ‘condensate’, is produced. If the condensate is pumped straight to the drain, it can have a harmful effect on the environment.
Left untreated, hard water can seriously damage your central heating system and boiler, washing machine, dishwasher, shower and household pipework.
The solution...

CalDensate is designed to treat the acidic waste produced by all condensing boilers. The tough, non-corrosive, in-line unit is quick and easy to fit. There is no need to dig a condensate trap. CalDensate is versatile – it can be fitted with all makes of condensing boiler – even those that are situated above ground floor level.
