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,

You are a ****ing idiot!
