Thanks, I will not attempt to make any changes

I have no idea what the function of the white cylinder is? The Schrader valve will not accept a tyre gauge to check the pressure if it is meant to be an expansion vessel. The secondary pump is a 15/60 but I will replace it with the original pump today, which I have tested and found to be working...

Thanks for your patience. I am going up to the building again this morning if any more photo's are required. It has suddenly occurred to me that although the boiler is new perhaps the fault is with the circulation pump in the boiler? That could account for the first five rads in the circuit...

No comment folks?

I replaced the normal type gold pump with a more powerful 110 green model which draws water downwards which then joins the cold inlet at the bottom of the tank. I will take photo's this evening and send in the morning. The original boiler was just knackered but system worked fine. It was an old...

We have a system, it works fine,. We yell out - I am having a shower so do not flush the toilet or turn on a tap, or switch on the washing machine. It works in our household.

The electrical supply to what I think is the central heating pump has been labelled 'secondary pump supply'.

I enjoy a pint at my local pub/restaurant owned by a hardworking Chinese family. I have had many years experience on property maintenance and they asked for my help. He had an old LPG gas boiler feeding a Santon Premier unvented cylinder feeding 23 radiators and hot water for the kitchen. New...

Thanks oldbutnotdead, I appreciated your comment. It hit the spot and was was the information I needed.

I apologise once more for being offensive if that was the case, it was never intended. I have spent many years being part of forums helping people with vehicles and engineering problems and I have contributed many times. I find that contributors can post a load of crap and in doing so cause...

My apologies if I caused offence, it was not intended.

I am having a large, (adjoined to my house) garage, made in to a ground level living space with an access door from the Dining room and rear yard. The house main floor is suspended to a height of 400mm so the new space (old concrete floor) requires to be increased in height by 200 to allow for a...

Thank you everyone, and you Gasguru. I agree. Primary HEX is fine, no tell tale stains. I will do what I can and look for another RGI instead of slapping new parts on it until a cure is found. Cheers, John.

Am considering ordering a replacement Vokera Easi Heat 25kw. I hope they are OK.

I agree, and I would not consider touching the gas side, that is why I asked my Gas Safe man who does the annual checks to do the job, but as I say on my opening comments that he changed the Thermistor but it did not improve things. Since then he has been busy, but was looking to order...
