thanks for all the help and comments people - finally got it sorted last night with the help of my plumber mate who actually took the time to look at the problem and work on it for a bit turned out to be an airlock and some draining, filling, venting and turning the pump on then off then on...

there is a vent tee'd off from the pipe going into the cylinder from the pump the pipe going into the pump from the boiler is at the bottom it comes up from the floor boards then has the overflow pipe coming off it up to the loft then goes up to the pump the return does split as it comes...

Backfilling?? i've tried just CH and HW on their own with no joy which makes me suspect a problem between the pump and boiler

the pipework under the floorboards and round the boiler is all old though - would a sticking magnet confirm a blockage or just a sediment build up?

does the power flusher just connect where the pump goes then? i've got a plumber mate coming round tonight to take a look and if there is a simple way of doing this (he might have a powerflusher?) would that solve the problem?

not yet - where can i get a magnet from? does it need to be a big one to move sludge blockages or just small one to detect them? Here's a photo - you can see the cold feed going into the return from the cylinder

yep - i've swapped it out to double check that so a newer one is in there! the configuration we have is Boiler - open vent - pump - cylinder - cold feed - which having done some reading isn't the best and can cause "see-sawing" but would this prevent the system from working at all? to me...

yep - pump valves are open and pump is dribbling water quite happily!

sorry the pipes get hot at the boiler but that heat doesn't get to the pipes around the pump! i don't really want to get the guy back who replaced the cylinder as he didnt' it just as a favour and i watched him replace it the cylinder as is - pipe for pipe - which is what i don't understand...

Hi guys, if you've been following my screwed up heating system - this is the next chapter bascially its an open vent system with a new cylinder, pump, 3port valve and programmer recently installed - everything is installed and working in terms of the individual items - the boiler fires, the...

fair enough - looking at it here's what i think 1. I believe so, although how can i prove it? the radiators are all full, the pump is dripping water and the little air vent going into the cylinder is leaking water - there are no other vents 2. all valves open - the tap on the cold feed and...

the pump is running, i can take the screw out and see the bit inside spinning round quite happily!

the plot thickens I got myself a tester and there wasn't as you said HW ON / OFF at the same time - what i am getting though is a constant HW ON from the programmer - even when the programmer says its off the HW is still going, if i swap the HW ON / OFF around i then get nothing at all from...

No joy on anything I've got the CH and HW activated but still getting no heat up to the pump - the wiring still gives current on the HW ON and HW OFF - its a fresh 5 core cable too i may just wire in the CH OFF and see what comes out of that - i'm out of ideas the valve is mid position at...

thanks for all the replies!!! yeah its a mess, it really is - the previous owner was a builder who did the place up from a shell about 10 years ago - and now we've got it everything is falling apart! the plumber who came round to fit the cylinder didn't say anything about the pipework...
