I know its been said on here befor some councils adopted this system years ago when they changed over from a coal fired back boilers with a pumped system to a free standing either wall or floor mounted boilers. I have spoken to many plumbers that had come accross this system in the past, not had...

saga finally finished at last I hope. 1) turned off gate valve that kept the cylinder topped up i/e the domestic tank ( the big one) 2) emptied the f & e tank to about 2" above the out let at the bottom of the tank and just before the operation of the ball cock came into play. 3) operated...

I thought that I made it clear in my last reply!!!! how ever I will make it short this time. No the vent pipe is not blowing over (as you call it) and 2 the water gets hot after about 10 mins. its comming back up the feed pipe at the botton of the f & e tank. the level of the water in the cold...

1) no, bungallow use to have a coal fire with a back boiler and a pump in the loft to circulate the hw around the place. And in the mid 90's the fire and back boiler was removed and a free standing oil fired boiler installed in the garage some 10 feet away and 6 rads fitted along with and...

no not yet, I fell off a ladder a few weeks ago cutting my hedge and only now being able to walk. I will have to sort it out soon befor they start using the ch :wink:

Kev the wiring dgrm that I did for the system is as follows its a honeywell 699 prog 1 & 2 terminals has a fused feed in via a double pole switch, links are 1-5-6 and 3-7. live from boiler & cylinder stat are wired to term 8 and the other side of the cyl stat brings in the DHW pump. Term 3 feeds...

it is a 2 pumped system 1 for the DHW & 1 for the CH. Its the DHW 1 that I am concerned about, should this pump be on the flow or the return and can the valve be fitted on the same pipe as the pump and should it be before or after the pump.

O no I'm not. it is the f&e tank i/e the smaller one of the two. The larger one fills up the hot water cylinder but I quess you know that :) it would appear that he did'nt even try two turn off the supply to the cylinder to see if the water level would drop as other forum users had suggested.

see todays reply, plumber came turned on the hot taps and said no its not the coil, if it was the coil the hot water would be contaminated, fitted a new ball cock in the fe tank (emptied most of the water out to reduce the level) and after 3 days the problem came back suprise suprise. and he...

my word that was quick, thanks plan c i new about i just wanted to make sure it was the pipe work that i was not so sure about.What about the pump

about this time last year I mentioned that my daughters bungalow had a 2 pumped central heating system and that later on in the year it developed a problem i/e water started to overflow fron the exspansion tank in the loft, and that forum readers suggested that it that it was the coil in the...

Hi again, I know what you are saying but like I said earlier it only over-flows when she puts on the hot was of a night so that she can bath the children and the amount that comes out is about half a gallon, and once she starts running the hot water it stops and after the children have had their...

will do :( watch this space. I will be going over to her house some time next week

I did have my suspisions that it might be the coil in the hot water cylinder but I was hoping some one would prove me wrong :cry:

no its not comming from the vent pipe or ball cock, its comming from the filler connection at the bottom of the tank. its a oil fired open system. the bungalow at one time had a coal fired back boiler which fed the rads and the hot water cylinder and the previous owner had it taken out and a...

my daughter c/h header tank is over flowing and its not due to a sticking ball cock or the vent pipe over the tank thats causing the problem. It only happens when she puts the timer switch to H/W only and it would seem that the filler pipe at the bottom (as if there was a back pressure) of the...

:cry: yes I realise that but at least they will look a lot nicer

Thanks for your imput, I will most prob, start afresh
