I have a Eco Tec Pro 28 boiler - it's about 5 years old.
A couple of weeks back we started having issues with the hot water supply from the boiler - when the hot tap is opened we get hot water as expected but within 1-2 minutes the temperature starts to drop off and then starts running cold. If I turn off the hot water and then turn it back on again the same thing happens. The central heating is working 100% fine - no issues at all.
I have a British gas service contract and they've recently made 2 visits to try to sort out the problem. The engineer initially thought that the system was full of 'gunk' and cleaned some of the internal workings such as the plate heat exchanger. This made no difference. They've since replaced the exchanger on the assumption that it's performance was being impacted by the 'gunk' in the system, but again this hasn't resolved the issue. They recommended that we fit a magna-booster filter, which I have for a cost of £280, and are also talking about the problem potentially being with the main heat exchanger, however this seems unlikely given that the heating is working fine. They've also recommended a Power Flush, which I may consider in the future as a means of basic hygiene for the system but I can't see how this will resolve the issue at hand.
Has anyone got any thoughts on what the issue could be? Apparently the sensors were recently replaced on the boiler too so between all the servicing and part replacement recently the kit should be almost as good as new.
Thanks
