Thanks Guys. Firstly I am not a retired builder, I owned a company that employed 25 specialist tradesmen (not in the plumbing trade), and we prided ourselves on paying our bills on time. I asked questions on the forum, seeking sensible advice mainly to confirm (from specialists) what i...

My neighbour came across a problem in converting from conventional to combi system, in so much that the combi system wouldn't maintain pressure. Eventually the installer looked under the floor and found an ORIGINAL (installed 10yrs ago) joint that had leaked unseen (only a very small amount)...

Fair comment, As I say I took the chance, and it worked. Can't blame you though...

Thanks for the info. The model number on the megaflo is CL250, and the imperial measure is my approximation (still work in pounds, shillings, and pence). At the moment the megaflo's are connected in parallel, and whilst I would like to try isolating one, and running the other (to test the...

Whilst I wouldn't disagree with the last comment, I have managed to bend the copper tails on a monobloc tap HOWEVER THIS has to be done VERY CAREFULLY. Firstly the the tails must be SECURE and watertight in the tap housing. THEN MOST IMPORTANTLY the bend should be as wide a...

As you may have seen from some of my other postings, I am looking at the layout/operation of a heating system installed at my daughters new home, which at one time had been two older houses. Over the weekend I have had the opportunity to make a more detailed observation of the layout of...

Thanks for that advice, unfortunately I need to put a tee on both flow & return pipes (obviously both) . The only way to avoid a tee under the floor, would be to lift a much larger area of tiles, which i would be very reluctant to do. thanks for the Hep2o advice though.

I need to bury some heating pipes under Tiles on a kitchen floor. I am almost certain that these tiles are NOT laid onto a wooden floor (worst Luck), and my questions are based upon the assumption that I will need to lay them into concrete/solid material. For various logistic reasons I...

Worcester 350 Combi boiler This boiler has a very small leak from the "bypass adjuster screw" which is set into the bottom of the HEATING FLOW AND RETURN MANIFOLD, which obviously means the boiler constantly needs repressurising. I have not yet removed the adjuster screw from the...

Simon, Tony, Thanks very much for your interest and feedback. I am coming to the conclusion that, in principle there is not a great deal wrong with the system, but adjustments could be made to improve it. My next task is to carry out the tests that I have already discussed, to build up a...

Tony. Thanks for your reply. I appreciate that the reversed flow/return is not a major issue (however it does possibly serve to illustrate the expertise of the original fitter.) Boiler setting is sufficient high to make the Radiators only just bearable to the touch. Motorised valve has...

Simond, Thanks for your comments, much appreciated Problem is that my daughter only recently moved into the house and we cannot be certain that the system did ever work, utilising the Combi boilers. It is more then likely that the immersion heater in each megaflow is the MAIN source of heating...

Will do.. It may may take a couple of days though...

I can only generalise on the layout surrounding this problem. In my daughters house there are 2 combi boilers in the cellar (the house was at one time 2 houses) . these appear to connect to common pipework which then splits via divertor valves to provide Central heating via one divertor and a...

Thanks for a very prompt reply. ... have just read similar topics and was coming to that conclusion...

My daughter has recently moved house. actually it was 2 houses converted into one. There are 2 combi boilers one in each cellar, which appear to be linked together. However my FIRST query (or plea for help) is: There are 2 radiators in the kitchen which won't get hot. The scenario is...
