I bought two gallons of white vinegar.

Pumped it in to fill the hot tank, switched off pump, opened all taps and switched on the electric, you could hear the bubbling coming out of the taps. When it went quiet I drained the hot tank and flushed through with clean water several times

Truma recommend white wine vinegar for descaling and a non-chlorine based steriliser. I've found that Puriclean works well and doesn't leave a bleach smell like Milton does. Generally I find that once a year is enough although it depends on how often you use it.

Hello dean,

The headline post was asking about descaling, which is the removal of hard water lime build up.

Bi-carb does not act as a de-scaler, it is an excellent cleaner, but it will not remove any build up of water-lime simply buy contact, and rinsing.

Next month i am having a new kitchen fitted, along with a new stop ****, as i live in a hard water area, i have purchased a maintenance free scale inhibiter.

Claimed life is 10 years, so i am hoping for 5 years effective use. It fits just after the stop ****, also i am having a undersink instantaneous heater fitted, so hopefully the heater, and the combi will benefit?

Anyway for

I'm not at all sure why scale should be a concern? given I service many water heaters from all over the country, only the odd one contains what might be called problem causing amounts.

The area that seems to be worst, albeit over a long period, is along the south coast, I've not seen amounts from elsewhere to cause any concern, except one recently?

I've just serviced one from 1996 and used, I'm told, all it's life in Hertfordshire, three or four large handfuls came out of it which was quite remarkable, never before seen anything as bad!

Thing is though, no amount of de-scalers is going to sort that out, it's needs stripping down and cleaning out.

Quote: "Thing is though, no amount of de-scalers is going to sort that out, it's needs stripping down and cleaning out".

Whilst this is undoubtedly true if the unit had been de-scaled regularly then the de-scaler would never had allowed it to happen in the first place. I think the OP was asking what to use and how frequently; not how to rejuvenate 13 years of neglect.

I use ordinary white vinegar [cant afford wine vinegar and both have the active ingredient acetic acid that we need], about 50% solution, left in for two hours [taps open to vent] and done annually. But I do live and camp mainly on the South Coast and being a CL user invariable have the water heater on.

I have never had the need to strip one down to check its clear, or have Truma boiler problems.

You should live in our area-West Gloucestershire! We have to de-scale our kettle monthly.
