Hi I have written and sent emails to various addresses and to date I have received no reply. In my letter I quoted some information from the advertising blurb for the magnabooster which stated that at the time of installation the engineer will determine whether a poweflush was required (one was not carried out so he deemed it not necessary) it also states that the magnabooster with collect the sludge and requires emptying at service. The service was carried out a month before and I was informed that all was ok with the system. If the booster had been emptied at the service I would have thought they would have seen excessive sludge and therefore, a problem, but they did not. The tentants have not complained since so I am assuming whatever they did when they were called out solved the problem. I must try and follow up as they could have at least acknowledge my letters. I agree that it is costly to maintain cental heating, but BG sell a homecare package for nearly £400 to cover repairs.

Hi Slick Thanks. I have just heard from the tenants that the problem was isolated to the upper floor and the system is now working ok since the engineer attended. I am surpriised it was only the upper floor if the heat exchanger was blocked, but I am not a CH eningeer. I am in the process of putting a letter together to BG, because after finding info on magnabooster, I am questioning why the magnabooster has not done what their blurb states it should do. I agree that if at the end of the day I do have to pay, £444 (only £275 not the £300 I first stated) is a much better price, but their first quote of £719 is well over the top. I have looked on the Powerflush Association site and they state the insurance companies like BG charge £600+, but their members charge for 6 radiators is more like £300. I will continue on my quest. Thanks Chez

Hi Slick and thank you for your welcome and reply. It is actually called a Magnabooster and since writing I have found the information about it and it states "Fitting this gadget in your home helps protect your boiler, radiators and entire central heating system from damage caused by sludge. This means everything will work more efficiently so you can keep energy costs down. It also stops corrosion causing expensive damage to your boiler, and can extend the lifetime of your whole system". The information also states, "Magnabooster isn't a substitute for Powerflush. If one of our engineers thinks Magnabooster would benefit your cental heating system, they will investigate whether a powerflush is also required." On this basis when they fitted the Magnabooster in Oct 2010 the engineer obviously decided that a powerflush was not required and according to their information about this gadget, I should not have got sludge etc. If I have then I am assuming it must be because the gadget did not work, also thinking about it further and from information on the info they provided , the gadget should be emptied at the service and if the engineer did this in January then he should have picked up the problem then (4 weeks prior to breakdown), so I wonder if he emptied the gadget. I will be contacting BG on these lines (hoping the system holds out for the tenants whilst this is going on), but I would welcome any further thoughts or advice from anyone. I will try and find a trusty local company, that that is not easy. Thanks Chez

Hi I had a heat exchanger replaced a couple of years ago (under a BG Homecare Agreement) and then it went again not too long after, so I was told that they would only replace it again if I had a magnabooster fitted, so I did at a cost of approx £300. It appears that they decided the system did not need a powerflush at that time. the boiler was serviced in Jan 2013 (funny but i always get problems after they have serviced it) and a month later I am told the heat exchanger is blocked up and they have cleaned it and that I now need a power flush at a cost of £719. I called customer services and the girl I spoke to went off and came back and said after speaking to someone in the office they were surprised I had a problem just after two years. However, there was not enough info on system would get another engineer to go out to property. Got a call this morning that they would reduce the cost by the price of the charge they made for magnabooster, but it needed doing. Any ideas on how I can tackle this with BG. Thanks very much in advance for any advice you can give
