You're right John! Not quite as bad it looks though, I'd opened the wiring loom to take it off the wall as it got in the way of the photo. It's secured again now. And the kids are nearly 30. Although one of the wires isn't clipped into the loom, so will need securing properly. Thanks for all...

Alright, got a picture, would welcome a second opinion on if I'm giong crazy or not. I took a photo of the backside of the pump and there is an arrow pointing down, so I have assumed that is the direction of water flow. I mentioned earlier about a bypass between the inflow and outflow on the HWC...

Thanks. I suspect the issue has worsened slowly over time by sludge build up and increasing the resistance of the rad circuit. However my mother (it's my parent's house, they're getting on a bit and somewhat vague) say it was all flushed out due to cool rads, a couple of years ago without...

Right ok, so making the Hot water side of things gravity fed while the radiator circuit was pump fed wouldn't be a good idea for a modern boiler? Got you, so definitely makes sense if replumbing it to put in a second motorised valve before the HWC, rather than move the pump.

Thanks John. From your first post I'm assuming you mean the coil in the HWC? There is no valve or way to restrict flow to that in the current piping. There appears to be a bypass with a valve outside the HWC, between the inflow and outflow to the HWC, but I think shutting that would still just...

One more thing, the outflow and inflow pipes from the boiler are both very hot, which fits in to my theory of the water bypassing through the HWC, while still leaving the radiators only lukewarm. I can't find any other bypass pipes anywhere.

Terry, I'll try and draw a diagram later, the cupboard is too cramped for a photo. John - yes, the hot water gets hot when only the heating is on. I left the water heating program off all day yesterday and the water was still hot. I'm just trying to decide if a) this was actually a reasonable...

Just edited the post, as I kept writing boiler instead of hot water cylinder, meaning the whole post made no sense.

Would be grateful for any help because it's driving me nuts. The problem, in brief one of hot water, but very weak radiators. I'm trying to get my head around possible causes before I possibly get the hard sell on a powerflush when I call someone round. System - F&E system, approx 15 years old...
