Hi, I would welcome any advice on the following. I have recently fitted an new en suite Mira select thermostatic shower which replaced the old one which was exactly the same model.The shower is fed from a Worcester Bosch combi boiler which was fitted eight months ago replacing an old combi...

Hi, I have a gravity fed heating system with a valiant boiler. It's a system with a hot water tank in the cupboard and a couple of tanks in the loft. Basically the problem I'm having is....... When the programmer turns on to boil up the hot water tank it seems to be turning on my heating even...

I have a Y-plan system with a Honeywell 4073 three port valve. The valve is several years old. There is a bypass gate valve across the HW cylinder coil. It is cracked slightly open as it always has been. The pump has always been on minimum speed and has not been changed. Since starting to use...

Hi again I'm on a roll with the plumbing questions today! So here's query #2... We've not used our hot water for quite some time, and it now doesn't work. From what I can gather based on what I've learnt in the last hour or two, I think the problem is with the 3 port motorised valve. When...

Hi all, Fitted a Worcestor boiler ( customers choice) got three zones ( two heating circuits, plus unvented) Would normally use heatmiser in this scenario but customer looking for budget option, any ideas? Thanks, Matt

recurring Issue, any help would be greatly appreciated. I have changed this valve twice in the last 3 years........ is this normal or would i expect to get longer use out of this valve?

Hi We had the issue with heating coming on when only calling for hot water ... had the three port valve replaced and 1 rad added where an old rad used to be. We still have same issue, the valve has now been replaced 3 times, i can understand 1 being faulty, maybe 2 but 3 ! It works for a couple...

Hello all I became a gas engineer about three years ago, so still quite unexperienced but eager to learn. Many thanks for letting me join.

Hi all, I have two issues that may be caused by one issue if that makes sense. First is that the central heating will only come on when the upstairs hot water tap is running (usually the three way valve from what I have read) Second is that when the heating is actually on the downstairs rads are...

It's happened before a few years ago and I changed the complete thing - valve body and actuator. Straight swap, Danfoss for Danfoss. But, now, after the heating has been off all summer, a couple of the adjacent rads get slightly warm when the hot water is on, so presumably the rubber seal in...

Hello — if anyone's got any ideas on this one, I'd be hugely grateful! Here are the details... I live in a small one-bed flat (on one level). Last year I had the water tanks and immersion boiler removed and replaced with a Vaillant EcoFIT combi boiler. The fitters rerouted the pipework as...

Hi.. My central heating had stopped working although till had hot water... after a search and finding the manual lever on the Drayton MID valve restored heat to the radiators.. I fitted a new one... I swapped the coloured cables one by one as the old one was in place so as to know I had the...

Hi guys. Hoping for a quick Three port answer. When wired to programmer tined switch?,is this the common wire to cylinder stat??. As what I'm trying to retrieve is when the water is used and goes below set temperatures to fire up boiler. Just trying to get heads up about the wiring again. This...

It's three years since I posted in these forums. (Then I was agonising how best to clean out 40-year-old pipework prior to having a new boiler fitted - all went well, with an excellent father & son removing the rads, hosing out a great deal of sludge, then refitting with thermostatic valves)...

Hi all I have a Vaillant ecotec plus (ground floor) and an unvented cylinder (top floor). This is an s-plan with a downstairs ufh zone and a single 1st and 2nd floor radiator zone each zone controlled by a two port valve. We have had various issues with the installer of this system. The latest...

Hi All, After been let down by several plumbers during a loft conversion my builders are now being held up... My old vented oil boiler will eventually be replaced with a combi boiler and I will also have three extra radiators in the loft. The old header tanks have been removed and I am left...

on a potterton ec three 215 e, what is comfort set point really fiddly control on that boiler, I couldnt figure how to get it on low flame or high flame and in trying, ruined the settings for comfort set point, i'm guessing its kind of like a frost stat and the boiler fires when ever the temp...

Lovely and tidy... Photo of a photo I took, apologies if the image quality is lacking... Ric

Evening All, I changed a Drayton three port valve today as the valve was completely seized. It appears to be wired correctly. When I switch to HW it moves to HW and when I switch to Mid it moves to Mid. But when I switch to Heating it clicks repeatedly, the small lever on the actuator stays in...

Hi all. I have three radiators in my house that are not warming up at all, the other radiators are hot. All the valves (they aren't thermostatic) are open on the three cold rads, and each have in-pipes that are hot to the touch, but the radiators themselves are uniformly cold. Bleeding the...
