Gentlemen I am leaving this thread now due to extreme frustration at all the misunderstandings and sometimes conflicting information given by different members, also there is ocasionally a hint of disrespectfull comments which is a shame in such a great forum. I have given all the required...

Under the back bed room floor boards there is a working pump so it cant be a gravity system, and it's possible that I have got the wrong "V" pipe but one does go up and leans over the F&E tank lip. Going out now to a celebration party so any answers will be tomorrow. Regards Ravel.

Ok here are my readings as taken after turning the boiler stat up to position 6 which is nearly maximum. Top coil pipe surface temperature =70.1 degs C Bottom coil pipe surface temperature = 60.2degs C Water out of bath tap next to cylinder cupboard =48.3 degs C maximum. Looks like...

Just so you guys don't think I'm not taking notice or failing to reply, I am going to do some more temperature tests at various points, but it will be later as Saturday afternoon is always shopping in Chester with my wife. Regards Ravel.

The pipe on your diagram goes from the upstairs airing cupboard through the ceiling into the loft F&E tank, and I,m not sure if you mean feel the open end for any air passage.

Yes there is circulation from boiler to cylinder coil, and the boiler stat on setting 5 normally goes up to 70 degs C, but I find my measurements at the coil input pipe rarely match those on the boiler indication usually being slightly lower. It is a pumped system with one 2 way motorised...

I did read all of the posts, and needed time to give the correct answers, but a domestic household problem occured which I needed to deal with, so please keep calm, and be assured I fully appreciate the help I'm receiving. The handheld thermometer with a corded probe is the RS 650-419 which...

No just a single one thanks. Regards Ravel.

The new thermostat is not faulty because it switches perfectly when an external heat source is applied and at the correct temperature. Regards Ravel.

No I'm afraid not it only reaches 45 degs C hence the no response, but this may be interesting just as a further test I switched on the immersion heater and after five minutes the stat changed over to off on my continuity test meter. Regards Ravel.

Thanks ChrisR this condition is common with most thermostats, but I feel it has no bearing on this situation as it's not switching at all. Regards Ravel.

I'm sorry Tony, and realise that's what should happen, but during the water heat up period the stat contacts are obviously closed, and eventually open when the desired temp is reached. This is not occuring and no change of state takes place even with the stat set at it's lowest 50degs C...

Thanks for your excellent info, appreciated. My main problem is to actually get the stat to turn off, or become open circuit The stat is a Drayton HTS3 which like most other makes has a bi metal strip at it's rear but there is always at least 5 mm air space between tank and sensor which is...

Hello Dave, no it's not connected to anything atm, I just wanted to make sure it did the switching before spending any more money. The result is it doesn't switch so my hot water heat input would be continous as the associated valve will be in a permanent flow condition. Would it be ok to...

Could someone please tell me which part of the CH cylinder in a vented system should be the hotest. I have poked my finger under the insulation jacket at the bottom, middle, and top, and found the top is definately in my case the hottest. My reason for asking is having just bought a...
