there will be a circle chrome coloured nut on the top of the valve that will still be attatched, this will spin off taking whats left of the TRV off of the valve. A new Drayton TRV4 head will fit on top of the existing valve but best to take the remenants of the old valve when buying the...

yes you can replace it and in most cases you can get the head on its own. What brand of TRV is it?

did you pay the extra cost for the bigger boiler?

sounds like your temp/pressure relief valve is faulty. The reason its probably running when your kitchen tap is on is because the inc mains pressure is higher than the hot water pressure. This is probably as the pressure reducing valve on the cold supply to the cylinder hasnt been set correctly...

the blue caps are in place of actuators. Screwing them down fully will give you no flow through that zone. Take the blue caps completely off and check the return temp in 30 mins or so. You should also check that the TRV on the flow to the manifold is not turned down too low and that the IV on...

Reading through your post I'd say that only a small amount of work would need to be done. A motorised valve would need be cut into the cylinder flow and some control wiring. I'm assuming the cylinder has a stat in place already so it's just some control wiring needed for the 2port and maybe some...

If the house isn't zoned is there any need for this? Wouldn't it be easier to set the downstairs stat to a different temperature when you go to bed?

If your thinking of keeping the old system due to a budget that's fair enough, if not it would be better in the long run to rip it out and start again. A newer system would be far more efficient and for your additional rads to be installed with your old system would mean cutting the 3" and...

From memory there's a link already in position on the boiler making the switch live permanent. If this is the case, which I'm sure it is the only damage you could do is have your wireless stat working in reverse. You shouldn't damage the main pcb as long as you wire the boiler up correctly which...

Hi all, my grandad gave me a call and asked if I knew why he's boiler fan kept running with no demand. As the insides of boilers are not my specialty I thought I'd ask you nice chaps on here. He's got an older style greenstar junior, probably around 8 years old. I said it could be something to...

the ideal drop rate on a hwsr is roughly 5 degrees.

If your installing a disabled ec without a close coupled cistern be aware that if the cistern is installed high it can give you a very strong flush and could splash onto the floor. I recently went to a school where 13 cisterns were installed too high and every one of them ha to be lowered 300mm...

Probably easier using a flexi pan con rather than and offset and swan neck together. It's not great using two together tbh.

I use drakes. Not a corporate giant but big enough to have everything I could ever need. I think there's about 6 or 7 drakes stores.

Sorry my mind was elsewhere, I meant evacuation tube setup rather that pv.
