Just an update for this; A common problem with these is dry joints on the PCB. On removal, it was apparent there were 4 dry joints for 2 relays. A quick resolder and all sorted - I now have heat - and have done consistently for about 36 hours now. Here's a picture of the PCB, the dry...

Tonight we're back to hot all over., pump is about as hot as the pipes, I can't keep my hands on either for long. The pump is gurgling still, there also might be a rattle inside it too, so it definitely needs investigating.

It sure is. The pipes are warm to the touch, estimate somewhere around 35 deg C. the pump body is hot, but you can still hold it. Perhaps somewhere around 50, just to give an idea. I've some a lot of reading about the Suprima, they are prone to electrical failures. Our boiler looks to have...

Have also just turned system off and bled an upstairs radiator. Water comes out, out looks surprisingly clear, but there's a definite hint of black in it.

ILast night it became hot too, but for the majority of the day it was warm. Today, much of the same - just warm. all radiators are very close to each other in terms of output, there's not one radiator that I'd consider to be better/worse than the others. If the thermistor is playing up...

Also, I'm not sure about the systems history, whether inhibitors or descalers have ever been added - I'm not much of a plumber but I'm pretty sure I could isolate and remove a rad, that's probably my limit if that gives you an indication!

Appreciate the reply. the pump body is definitely hotter than the the connected pipes, but I wouldn't call it extremely hot. It does gurgle when on, I've assumed air is in the system. Its a grundfos, but the bleed screw is not very accessible due to the pumps vicinity to the HWC. Boiler...

Hi all, looking for some guidance. A simple heating system. potterton suprima boiler, gravity fed feed and expansion, around 18 years old. Its powering a 3 bed detached, hot water done by immersion only. have set boiler stat just short of max, and room stat at 25, but house rarely get...
