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 =A3250 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.
Simon
