Hi, I have a hot water cylinder which feeds 3 outlets (kitchen sink, basin in bathroom & bathtap) which has never had very good pressure (probably because of the set-up) but last year got so feeble that a guy suggested fitting a pump alongside the cylinder. This can work fine but then all of a sudden can lead to a complete cessation of hot water, he has got it working again before but it stopped the other day and he wasn't available to resolve so another really useful guy came and sorted it with a hoover in no time but said it could be the pump drawing off the hot quicker than the header tank could refill the cylinder (and we ought to have a flange on the top of the cylinder as well-even though it doesn't supply hot to a shower) and, as he predicted, we are back to it being stop/start.
I've put some photos on that show the set-up, (which is identical to other flat owners, although their pressure was never as bad as mine before the pump was fitted), I was wondering if there is something inherently wrong with the set-up (I think the builder of the flats used a cylinder which could also be used as indirect but it has always been immersion only) and whether having the pump is causing these airlocks ?. We were thinking we might be able to install a header tank with more capacity although tbh I'd rather just not have the pump and I'd be happy with just reasonable hot water pressure.
Hope the experts might be able to offer some guidance, I'm considerably better at sawing things ! cheers
