I want to descale the plate heat exchager on my boiler this weekend. Where can I buy spirit of salts from?
Also, how long should I leave the SOS in the exchanger for?
Will it damage the metal if left too long?
Will SOS also clean the primary side of the P Hex - not that I think that side is a problem?
Thanks
