Hi all, I'm looking at replacing our rather dated Potterton room thermostat that controls our Potterton Suprima (30 I think it is) boiler like this one; https://www.plumbcenter.co.uk/product/potterton-prt100st2-room-thermostat-spst/ With one like this one...

Hi all, I'm after a bit of advice and may have many, many questions in regard to this project we are only currently thinking about. At present the side of our house looks like it does in pictures Before front and Before rear attached. Could we add something like in pictures After front and...

It's old, about 18 years. The boiler itself is fine, it's all the gunk, rust and debris throughout the system and radiators the needs cleaning http://www.diynot.com/diy/threads/plinth-heater-woes.453423/

Hi all, We have a Potterton Suprima boiler and the whole system needs a clean and inhibitor. According to this site; http://www.kamco.co.uk/AlHeatX.html the boiler has a aluminium and cast iron heat exchanger. Am I ok to run Sentinel X800 through it and then drain and add inhibitor? I'm asking...

Success! It was blocked isolation valve end, a good 4 inches of it. Flexed and poked and flexed and poked and flushed. I just need to treat the entire system now. The water was so black and rusty it's as if it's never been treated, ever!

I've tried two different sizes of wire with the valve both open and closed

It's a Myson The valve is an integrated part of the flexi

I've tried to unblock it in situ but failed. Next step (probably over the weekend when I have more time) is to plug the F&E and remove the flexi and attempt to unblock it without damaging the rubber inner. I was just looking for a replacement in case I can't unblock it or do damage it

I've been looking for a suitable replacement hose on Screwfix and I read that not all are suitable for heating so at the moment I'm unsure as to which to get

It's the return flexi that's blocked, the feed is fine

Well it's the flexi, totally blocked with large rust fragments/rusty water. The only way I'll even stand a chance of unblocking it is to totally drain down the CH and remove the flexi connector. I'll have to give that a go some time. I just hope none of the copper pipe is also blocked

Yeah it's vented

What about fitting some kind of vacuum pump and sucking the blockage out? I'm just thinking out loud here

Thanks Madrab. Bugger, a lot harder than I thought then :/

Hi, thanks but I don't understand, sorry I'm not a plumber, I'm an electronics engineer lol. So, I connect a hose pipe to mains pressure, say, my washing machine feed, then connect the other end to the pipe thats blocked, the one that connects from the out of the plinth heater and goes back up...

Thanks gigz, that's what I thought but again, where will the crud from here go?

Ah I see what you mean, I think anyway. Water flows through the heater itself fine now though, it's the pipe that goes back to the rest of the heating up the wall.

Hose pipe from cold mains pressure to both the in and out pipes, is that what you mean? A quick burst? If it is blocked and I do this where does the crud that's blocked it go?

Hi all, Hoping someone can help. We have a plinth heater in the kitchen, the only source of heat in there (other than the oven lol) and it's never worked for the 4 years to the day today we've been in the house. Today I decided to take some time and have a look at it. Electrically it seems...

Is there an easy way to properly identify which one of them has the vent pipe on it?
