The radiator doesn't heat after i've added a plastic pipe to it

[Andrii]

I did turn off 4 radiators downstairs - just to check - and it heats much better , let say 50 - 60 % . But once i turned on the 4 radiators - it cools down , and becomes cold

I will do another check tomorrow - with all radiators turned off - but i think it will be just what happened this evening with 4 radiators off.

Thank you

wont work untill you turn all of them off as you need to run it enough for the heat to go back down the return and back to the boiler untill it circulates

It seems like it needs balancing. Get an engineer in.

i agree needs balancing properly

I think B&Q do a leaflet on balancing heating circuits.

Why would you do it, if you don't know what your doing. Don't need to be funny but what would you do if you used a wrong fitting or something and flooded house , i just don't get it lol

agree as said because of adding the extra pipe the whole system now needs balancing to compensate, because a 15m run of pipe is adding a lot of extra resistance to flow that was not there before

I'll try to a system balancing - if that wont work , i will remove the radiator and connect the pipe directly - as is more likely to work with pipe only - than together

Man , That looks like a cowboy job, what were you thinking??
