Cannot get new radiator to heat up?

[mbc0]

ok, thank you for the advice on the isolators, I will remove them. With the issue I have though, is it sounding likeley that I have a blocked/damaged pipe? should the water flow from this pipe the same as the other? it makes no difference to the flow whether or not I have the isolator installed or removed. I am really at a loss as to what to do next.

the pressure should be the same. When you’re testing this is it with pump running?

Apologies if I’ve missed it but is this microbore? And is the radiator a column style radiator?

Hi,

It is a Revive 500h x 1100l Double Premium Radiator (P+) standard radiator with 15mm pipes (a link to the pictures is on my 1st post)

Hi, that is worrying :-( yes the pump is running at it's fastest speed. as the pipes are under concrete I can only get to them in the hallway. Maybe I will have to drain the system again and cut the pipes in the hallway to try and clear the blockage unless anyone thinks a power flush could work?

 

[Riley]

A powerflush will probably shift it. Did the previous rad work?

 

[mbc0]

Hi, yes the previous radiator worked but was removed for 3+ months and then the new one installed after I put up a new wall and re-plastered.

Ok,

An update!

I disconnected the radiator again today and removed the isolator on the right hand side pipe and there was no water coming out, even though the pipe this side gets red hot and the left hand side pipe that is stone cold flows perfectly (but then gets hot very quickly when flowing into a bucket)

I connected a pipe from the mains supply to the right hand side pipe and blasted it for about 5 seconds. after the 5th or 6th time a ton of crap came out the pipe and began flowing as well as the left hand side! I filled a couple of buckets and the water became clear so I reconnected everything filled the rad and everything was working normally for about 4 hours and now I am back to square one! At least I know the issue is due to crap in the pipes I am now looking for a way to connect a foot pump to the pipe as I believe this will be more effective!

I did say first off it sounds like a blockage. A foot pump is going to be hard work to say the least. I would consider a powerflush, if done properly with the right chemicals should break down any obstruction, prevent it from reforming and improve overall performance of system. If you could isolate problem leg and blast with compressor this should clear but poses risks to any existing fittings. I’m interested to see what those with more experience suggest?

Do the same again

 

[Riley]

Be careful pumping air in. It can push crud to all other parts of the system.

Another thing is a suction pump with right couplings. I’m aware there are several on market but I will suggest the ultimate suction pump, when on Facebook I’m a member of an oil fired group and the producer of this product is as well, I know his product quite well and when used correctly can suck most crap clear, amongst other functions.

 

[Riley]

Aye aye

I am interested in what you are suggesting but haven't quite decoded what you are trying to say!

Hi,

I will definately be doing a powerflush but not until I am draining down the system to install a new rad in the hallway (no pipework there yet) it would be nice to see if I can clear this pipe before hand though!

ok, noted, thank you!

Millions of products on the market for cleaning the CH System, are there any clear winners or are they much of a muchness?

 

[Riley]

Proper powerflush by which i mean that the correct chemicals are used, each radiator is treated/flushed individually and it’s not completed in a couple of hours

 

[SJB060685]

Like Riley says a power flush is a minimum one day job. On larger systems I’ve had to split system up and do over two days. Each power flusher will tell you what it’s capable of. A suction pump creates a vacuum and quite literally sucks Rubbish out. I’ve used them to clear oil lines or bleed problematic lines and vent de aerators

Reputable manufacturers: sentinel x800, fernox f3, calchem 3 in 1 (breaks down and don’t have to drain out)

 

[mbc0]

Thanks for the replies, I aim to drain down in a couple of months to install the new radiator so that Calchem 3in1 would be perfect, shame no local shops sell the bloody stuff though!

Yes, Thanks mate, I am heading down there this afternoon, I was going to drain that radiator, have another go at blasting that pipe again today then putting this stuff in the radiator when reconnecting! fingers crossed!! Thanks for all your help

No worries, glad to be of some help
