My mum has had a recommendation from a British Gas engineer to fit a
Magna Booster to her central heating - which apparently removes lime
scale from your central heating system and 'stops it from blocking up'.
The charge for this is £250 parts and labour. She lives in SW London -
the water is quite hard.

Is this Magna booster a good idea - or a useless gimmick? My mum has a
Potterton conventional gas bolier fitted about four years ago and is on
a service contract with BG.

Useless gimmick IMO. Dr Drivel will no doubt differ, but he's a nutter
(really).

If you do decide to go ahead, get quotes from local plumbers. Will be a
LOT cheaper than BG, and the workmanship will be better.

Example: I asked BG to quote for a boiler replacement a couple of years
ago. I also asked for a quote from a local, trusted plumber/heating
engineer. The local chap's quote actually included some additional bits,
as it turned out.

BG (with £600 discount included) - about £3250.
Local man - £1900.

And that was with a better boiler as well.
