4 MISTAKES YOU MAKE WITH ONE COLD RADIATOR

Don't make these 4 mistakes when trying to get your radiator working!

Don't make these common radiator not working mistakes! If you've got one cold radiator on your heating system when the system is on, don't make these common mistakes like hitting the radiator valve pin with a hammer. It's crackers.

Balancing is one of the best ways to ensure that your house heats up evenly upstairs to downstairs. Great tip.

Thanks a lot mate, great video, helped fix my radiator.😊

Surely if the heat from a router can shut the trv, then won’t the heat from the radiator itself do the same?

[andyhello]

Thanks for the video, in combination with other videos on subject you all do it slightly differently

You are a funny man with great knowledge 👍

Those Aladin auto venting air valves will fail to work on an old system the second time you need it. Fitted new the vent (pin) hole in the back of the value will be open. As soon as the radiator fills and there is any sludge in the radiator the small hole will block up with sludge. The next time that you drain the system the blockage will remain and the valve will not work. There is also a secondary problem with the way they work in that there is a membrane that gets wet and swells. When dry this membrane lets the air out and when the water reaches the top of the radiator and the membrane gets wet it swells to stop the water exiting. When you drain the radiator the membrane is still wet and if you fill the system again, say, a few hours later it is still wet so no air is released. Heating the radiator would dry it out but full of air the radiator remains cold. The valves are an expensive snake oil product! First impressions when newly fitted, a great product, BUT you don't find out about their problems or limitations until you need further work on a system.

Why would you close a TRV in the summer ?
My CV is on 'standby' 365 days a year, every year, it just doesn't switch on as it always too warm in summer.

In summer are you meant to close the trv to min and open up towards autumn? Or the opposite?

I had my boiler serviced recently. Since then, two radiators downstairs (boiler is upstairs) will not work, one downstairs does work. Ive watched so many videos, nothing works, tried balancing, etc. Pipes going into those two radiators also not hot.

Hi plumber parts. I've got a problem . I've been renovating the bathroom but I can't seem to turn off the hot water as I can't find the turn off valve . The cold water in the bathroom is turned off .I've looked high and low but can't find the hot water valve to turn off and it's holding me back from tiling the shower room and putting in the vanity unit in the bathroom. Is there a video that shows different scenarios concerning turning off hot water supply. Been like this for a couple of months . Been taking a bath in one of those buckets you mix plaster in ect . Would appreciate your advice and knowledge. Love your vids full of info and entertaining. Good banter . Better than watching TV. I think that every house across the UK should have a easy to find manual concerning plumbing . Gas . Electrical points . That would help the house owner but especially the tradesmen.

James, why did you take the self balancing rad valves of.

[stephenweston]

I worked on a TRV where the pin had jammed down. So I gently pulled it with some pliers and it promptly popped right out! (obviously it's not meant to do that). Fortunately I was able to reinsert the pin and hold it in place with the TRV. Almost a brown trouser moment.

Don't you set the flow on the valve under the TRV itself and not on the inlet of the radiator???

Hi guys, I have an issue with only one rad in my system. When the CH is on this rad wants to remain cold, however I can feel that the lockshield side gets hot aswell as the pipe, but the TRV side remains cold and will only ever get lukeworm. When I remove the TRV from the rad and open the TRV, there is water gushing out. Does anyone have an idea of what may be going on?

Got a TRV that lets in heat when I have it switched off (I dont like to sleep in hot room) So I want to just look at it, do I just unscrew collar, remove head, bounce the pin up ans down gently as shown and spray a little bit of WD40? I open it to 5 before hand dont it?
And have the boiler turned off? (its a combi) before re-installing the same TRV head?
Advice please, I'm not draining, or bleeding or gonna get wet or anything I am????
And the boiler goes off at the mains during this?

[grady]

I would love some advice, got a rad very similar to this which does not get properly hot, its more warm and not all vertical pipes same warmth. The trv pin is stiff but to be fair so are some on other rads in the house which get mega hot. Ive had it balanced once before but didnt do the trick. Its as if it starts heating up and then shuts off and then starts again. With it being steel and heavy it takes an age to warm up and this process just kills any chance of it being effective. So should i mess around with the pin or does it sound like trapped air etc? Great vid by the way, tonnes of useful info!

I was told by a Worcester engineer that a room thermostat replaces the TRV as the thermostat senses the room temperature & shuts down the boiler.

Question, I have a radiator that was cold. I took the trv head off. I gave the pin a bang before 😂 before I did it before i watched this video.
Back to my question, the radiator is now working, but the pipe to the trv is warm. The lockshield side is very hot.
What do you think could be the cause of that?

[mda]

Question: Why do they say only bleed the radiators when the heating is switched off? I very often bleed mine when they are fully working and it doesn't seem to make any difference other than the water that dribbles out is a little warmer.

Why do people have a TRV on a radiator when there is a room stat in the same room as the radiator?
