Hi

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.

Thanks for you advice.

Could that have been "Magnaclean" rather than booster? If so, it only
really seems to treat a symptom rather than a cause of a problem anyway.

It protects the heat exchanger as it is on the return. It also prevents
radiators sludging up.
