So the gas fitter came to call....

and expressed concern about using an ion exchange (salt) water softener
with a thermal store. Corrosion of heat extract coil due to salt content
in treated mains supply.

Google hasn't found much apart from now discounted worries about boiler
heat exchangers.

Gledhill technical advice dept. were only accepting voice messages
(poets day?)

Anyone come across this. In 25 years it has failed to penetrate either
the side walls or the coil in our hot tank.
