Yes there's 240v on the motorised valve

I have problems with my CH system. it looks like the motorised valve isnt working correctly. You can manually set it to be CH and HW, CH, HW. But it doesnt seem to do this when controlled bu the controller. I have changed the motor in the motorised valve but that doesnt seem to have made a...

Ive tried that but still no joy. If I put an inhibitor in the tank will that help me. Or will my air lock/ blockage still be there?

Thanks I will go and find my magnet

Thanks for this I have been up the loft and the tank is full of water. The ballcock works ok. I have 2 bleed valves in the airing cupboard and neither of them have any water in them. So I don't know what Is blocking water getting to either of them there is a T valve (or is it called a Y...

My central heating system is about 30 years old , but has had a new boiler, about 7 years ago, It it now having the following problems. 1. The pump sounds like it is pumping gravel. Increase the speed and it gets louder. 2. When the system comes on we get a lot of banging for about 10-20...

I hiave 1mm gap at the top, beteen seal and widow, and it is tight at the bottom, where the open handle is. The hinge bracket is like your picture.

I have a upvc window with two upside down v shaped devices at the top which is connected to two levers. And the window pivots from the top. It is a bottom opening window. The guy who installed it told how to adjust it as one of my others was faulty, ie it just needed adjusting, which he did...

I have a worcester cdi 30 boiler and in the last 2 nights it just turned off my heating. Last time I reset it and it came back on This time it comes on for 10 secs and then cuts out. I know it has been on for the majority of the last 5 days but the hot water is still piping hot but all...

In the end I went with 16 240v 50 w downighters, on the grounds that a mate said that there wasn't much difference in the quaility of todays GU10 and there halogen equivalent. I must say I agree with him. I am pleased with the result I brought 50W and split them using a 4 way light switch...

Thanks DIYISFUN and Tennooge. What do you mean by main carcass? Is this like a manifold or something? Can you just not chain rads together or connect them in parallel. Excuse me if I am not up with the terminology.

Sorry, the one that wasn't working, got hot only at the top. The other one, that wasn't working, did not get hot at all. What does this mea? Only decent plumbers to answer please.

i turned off the next radiator, nothing happened, I turned of the next one in the chain and the radiator got slightly hot at the top only, I haven't turned any more off. Whats next?

The rads were run from the nearest rad, one in the new conservatory one in the kitchen. Same pipe sizes 15mm. My mate is bit of a dreamer, but I may have misheard him as he says my CH system is really weird. e.g, when I changed the speed of my pump it sucks air out of the overflow and a get...

I have had 2 new radiators in my new extension which don't warm at all. I have been told to balance my system. Do I need a thermometer to do this is there another trick of the trade to use. My plumber mate says I need to put bigger pipes in my feed from the header tank, but I don't understand...

Sorry, My system is a Worcester greenstar conventional CDI boiler, Y system with a two way valve with a header tank and pump. My new radiators have TRVs on them. I did have soe sludge in my system which my plumber mate got out. The pump has a switch on it that switches it to the higher...

Here's one for you! I have recently added another 4 rads connected to my system. I upgraded my boiler to cater for extra rads.Since then we decided to put my pump on the next speed to heat up the new radiators in the new conservatory. In started getting a gurgling nose when my CH comes on...

Here's one for you! I have recently had another 4 rads connected to my system. Since then we decided to put my pump on the next speed to heat up the new radiators in the conservatory. In started getting a gurgling nose when my CH comes on. And I could bleed some of my Rads on a daily basis...

Well thanks for the help oilman, :( . Suggesting to get someone in, surely goes against what this website was set up for. I have a conventional gravity fed pumped Y system I think it is called. I have had the boiler replaced with a condensing boiler when I had my new extension as I have had...

My CH system gurgles when it starts up and I have to bleed my radiators in my bathroom and bedroom on a daily basis. My pump is fine on one speed, but when you turn it to the faster speed my central heating becomes very noisy sounding like a kettle boiling or an repetitive gurgle every 2-3...
