    central heating only comes on with h water, stumped engineer

    As for the tests, i have just retraced my steps to make sure which pipes are getting hot 1st, the pipe to port ab definatly gets hot before any other pipe including the pipe from the cylinder, so unless it can be explained how this is happening as a return, this must be the flow. I have also...

    Hi, i have managed to get the fore off the boiler and as some of you have been wanting to know, the pipes arnt connected as i thought, but they appear to be connected like the baxi bermuda inset 2 manual shows. The only part i cant confirm at the moment is what the 3 pipes are conected to...

    There arent any pipes in the old position other than the 2 28mm which pointed left in the pic and went 1 foot, turned the bends on the top 90 degrees and added 3m of straight pipe to cylinder

    Yes the bit of pipe is just a spacer. Moved the cylinder by lableing all pipes, cutting them and reconecting, in the loft i replaced and moved all water tanks and took all water feeds and vents strait up from new position of cylinder. I have not touched any pipework under the floor. The only...

    is it not likely that the return is the bottom 22mm to the boiler, how can we find out if this is the CH return? if i am to swap the 28mm pipes over, this would be so much easier to do between the conduit and the cylinder/pump. Before i do this i think i will get the boiler serviced and try to...

    yes i do mean cylinder. the T to CH is the 15mm under the floor which goes down the conduit, this gets hot when Prog HW, 3pv mid and not when HW and 3pv HW. when the pipe to pump gets hot with 3pv set to HW,the pipe out of the bottom of the Cyl gets hot 2nd
