MagnaClean and Hydroflow recommended by British Gas: worth it?

[Dave Plowman (News)]

Quite. Makes me wonder how my system has worked just fine for 40 odd years without one. In London, which is a hard water area.

Same with the way they push Calgon at you. I had to change the heater element in our washing machine after 12 years (hard water area). But it had practically no scale on it - the integrated gasket had failed.

Interesting to work out the cost of using Calgon in each and every wash over the average life of a washing machine.

Absolutely no evidence these magnetic/electronic descaling/ hard water improver devices work.

Ion exchange softening devices do work. (The ones you put salt in).

OTOH The magnetic traps for your central heating circuit are a good thing. Especially if you have had a new boiler fitted.

If your fitter can't get an immersion heater out of your cylinder, he is a tosser. I used to do this regularly years ago and never once failed.

Perhaps he's worried about destroying the tank. They don't build them like they used to.

No, he is a tosser. Probably got an NVQ. Or there is a financial incentive/work creation.
