When I say the rest of the house is up to temp I mean it's warm enough. We have TRV's on all rads except the new one and the bathroom. There is no central room stat to turn the boiler off. There's a programmer and the TVR's. Even though they're supposed to limit the temperature if the...

I've recently installed an additional single rad via a motorized valve, but have found it's not staying warm. It appears that when the heating first comes on it heats up well, but then as soon as the rest of the house is up to temperature and the boiler is just cycling the water this particular...

D Hailsham - That's fine. I am using it as you describe, but aren't worried about the area not getting up to temperature if the rest of the system is turned off. The new rad's in a conservatory, that will primarily be used as a play room, but only three days a week when the lad's not at...

OK folks. Drained system and re-filled - the new rad now gets warm. Obviosuly an air lock. On a related issue - how much does a MV restrict water flow? The rad isn't getting hot very quickly so it looks as though I'll have to wind all the other lockshields in a half turn or so. Would this...

KevPlumb - Unfortunately it wasn't on manual - but it would have been open as the room stat was calling for heat at the time.

KevPlumb - Best way to remove an airlock? This valve has been installed under a ground floor, lower than the bottom of all the ground floor rads (inc the new one)

I would consider the actuator the electrical part (motor) that can be detached and the valve the brass part that is left behind when the actuator is removed that is connected to the pipe work.

Actuator or Valve?

Just fitted a Horstmann Zoneplus F222m / F222i 2 port valve on a new radiator controlled by a programmable digital room stat. When the stat is calling for heat you can hear the valve move, and then move again when it switches off again. The rad is filled and bled OK, but there is no water...

I've done the job and answered my own question! It can work from any panel - and can be programmed to accept varying triggers, 0v applied, 0v removed, 12v applied, 12v removed etc.

I've got to replace a Pyronic Paragon Super II alarm panel that has a Pyronix Vocaliser connected. Is the Pyronix Vocaliser able to work with any control panel or just Pyronix products?

Hello everyone. Brickies coming this week at short notice after another job was called off. Hence a rush to get some gear for him. (For conservatory) 5 courses up to slab level total run 10.21m. I reckon this means I need 476 bricks with 4.65 bricks per linear metre. One full height...

Does anyone know whether the Cellotex currently sold at Wickes is suitable for use in a concrete floor, or whether it's just for wall or loft use? I don't seem to be able to find a reference to check with on any at my local store. I would ask someone in store, but would not be suitably...

Hey guys - it was only a thought! I'll do it properly - honest - will even take some pictures to prove it! You've made me feel really bad now, particulaly with the thought of all that extra digging and barrowing. Not to mention probably another £140 skip that'll be required!!!

Hey - I was just thinking. It would be much easier to just route the rainwater pipe straight into the SVP below ground adjacenet to the wall wouldn't it. Who would ever know?.......

I was hoping you'd make an appearance Noseall. At the moment I've just replaced the clay pipe with plastic and connected up just in case it rains tonight as I didn't want the footing flooded with the cut off end discharging straight into my nice shiny new hole! In the back of my mind I was...

I'm doing the base work for a conservatory and on the last section have found the following... http://www.flickr.com/photos/36052596@N05/3643818710/ I've read various bits on this forum about compressible material around drains in footings etc, but is that when they are just crossing at 45...

We are having a conservatory built for which we are doing our own base work. The conservatory surveyor has been round today to go through measurements etc before we start and has said that they mainly build a solid wall rather than a cavity due to the fact that it makes the frames impinge...

MK do their own range of RJ45 sockets to go into 1, 2 or 4 gang logic plus faceplates. Why don't you just use them?

The CAT5 is for a 10v dc control signal. It's being used for controlling dimmable ballasts on a lighting control system. My thoughts were that surely you can't have 10v dc cables (not rated at 230v) in the same trunking as 230v? If this is all OK, why do we bother having different trays...
