Enough of this vague bulls**t - please list the components in your system, including quantity of radiators and floors in the house, boiler make/model, and size of cylinder.
I have a worchester greenstar oil condensing utility boiler fitted 25/32 . I have 24 Rads on it, 11 downstairs 13 upstairs. (Sounds like a lot of rads but I will only have half of them on at any time, My Cylinder is approx 1100mm high.I also have a Groundfoss Pump and 3 zone valves by the boiler and 2 RF Room Stats
The plumbers came in and put the new boiler in and at the same time zoned upstairs, downstairs and hot water. It used to be a gravity feed hot water system, they changed it to a fully pumped system
Next, please explain why you replaced the F&E cistern when you had plumbers in the house working on the heating system. Why did you not take their advice, better still ask the plumbers to do the
plumbing work?
I replaced the F&E Tank between the plumbers coming in to quote for the boiler work and them auctually doing the job. The tank was in before the plumbers came in. Apart from the fact that the Tank may be Large I'm 100% Happy with the tank, that is not my probem, it was just a straight change over with only a little bit of pipework that I could do myself. I really needed to keep this job done on the plumbers labour, that is why I did it myself.
Next, please explain why you isolated the supply and filled the cistern when other people were working on the system.
First I only isolated the supply ready for the Plumbers to work on the Boiler etc, I only refilled it when they told me to after they had fitted the Boiler and finished thier pipework. The Boiler was not fired up that day because it was late and the electrics were not finished. It was only then I isolated the supply for piece of mind because thy were not returning for 5 days. The night before they returned I went to turn the suppy back on and that is when I noticed the water drop in the Tank. I have been keeping an eye on it since and it has been dropping steady, it dropped about 40mm in 4 days (25 gallon tank).. The other night I ran the downstairs heating for half hour then checked the tank and it had drop 20mm more just in that half hour, the next night I checked the tank and it was nearly empty and the boiler had not been on at all.
Next, please explain how on earth you expect to get any warranty from the plumbers you engaged when you're cocking up their work.
I have done no work after the plumbers have finished, all I did before they came was install the new tank and fit TVRs to the rads.
That should keep you busy for long enough to take your mind of the complete irrelevance of the TRVs.
The reason I mentioned the return getting hot before the flow is because it was not like this before the plumbers work was done.
I have just noticed is that I just tried the downstairs heating on...
Why have you filled the system without a corrosion inhibitor?
Or, if you added a dose of inhibitor, why did you do that before finding the leak, given that you'll have to throw it away immediately?
I have not put inhibitor in yet I'm waiting to make sure I don't have a problem, then I will do it.[/quote]
I have been told maybe the system still has a lot of Air in it and it is settling down. I have bleed the rads, would the tank level drop steadily until all the air is out?
My worry is that downstairs my Central heating pipes go under a concrete floor, I'm concerned that I may have a leak under the concrete and that is where I'm losing the water.
I can see no evidence of a leak.
I will be phoneing the Plumber Monday to get his advice, I just wanted to try to work out where the water is going before I contact the Plumber.
