I know you said that 15mm is adequate for the pipe drops but should the pipework leading to the drops be 22mm as we notice that there is a lot of 15mm pipework under the floorboards. We changed the pump a couple of months ago and it does appear to work harder on speed 3 although it doesn't...

if the pipework is clear,it seems possible that 15mm wall runs are not up to the job .-short of doing a whole re-plumb around the house ,would converting it to a sealed system by buying a sealed system kit(boiler instructions say it will work on a sealed setup) possibly improve matters

yes the pipes are dropped down the walls to the radiators(concrete on ground floor) flow from pipes with rad off seems good-pipework down all walls is 15mm

UPDATE- just opened up all lockshield vales and trvs upstairs on 4 medium sized radiators(single convector) 3@ 2ft x 2ft and 1 @ 4ft x 2ft and all of them are red hot, however they have sucked what little heat I had from all the downstairs radiators

Hi chrishutt Thankyou for your patience and time. No we do not appear to have an isolating valve. I am now wondering about an obstruction, however I did cut the feed pipe close to the tee by the pump so I could connect a hose pipe and flush each pipe individually - flow and return and there...

Hi Chrishutt Sorry if we're not answering your question properly. I will run through the sequence - for example - 7.00am controller switched on for ch only, actuator is in position (to the right) to then supply ch only. Pipe to hw water tank is cold. When in ch mode only very poor...

Hi Chrishutt Yes we still have poor circulation when in the CH position and HW is off.

22mm pipework from boiler to pump is red hot, 22mm flow from the pump is red hot then it goes under the floor boards. Boiler is situated in utility room on ground floor of standard semi with pump in airing cupboard on first floor.

Hi Chrishutt Sorry not too sure what you mean, however when the mid position actuator goes to the centre when heating and HW are called for the CH cools as its supplying to both CH & HW. When in HW only it heats the water with no problem. Only problem we appear to have is with CH. Hope this...

Hi Chris Just been up to the loft and double checked - not pumping over.

Hi Thanks for the reply. The bypass loop is shut off fully (for testing purposes). Hot water is fine - motorised valve (mid position) is working perfectly. No corrosion in system as this has been fully flushed and checked.

Hello. We moved into our house in April last year and didn't notice any problems with the heating - the weather being warm enough only to need slight heating occasionally. Come the winter and we have had major problems. We have a Glow worm ultimate 60FF vented system with 10 radiators - 5 up...
