Hot water/heating was not coming on in the evening and not getting hot enough in the morning. We have Homecare cover with British Gas so called them out to fix. Engineer installed new control/timer box, which seems to have done the trick, but he also said alot of our hot water pipes had furred up (copper pipes became magnetised apparently - that's how you can tell) and we should have the system Powerflushed for £595 to remove all the debris. And until we do, our water pipe cover (incl cold water pipes) would not be covered under our policy.
As a born sceptic, I thought this might be a bit of a con/money spinner. Looked on websites/comsumer forums and seen some positive comments and some negative ones.
Anyone got any experience of this sort of thing and can offer advice? If we do get BG to do it, any future powerflushes would be free. Thanks.
