The water in some rads is a bit black, all the system is going and it’s very warm very vey warm hot water and rads. My pump is on the slowest but it still has water going in the header tank. It’s faster with just the hot water on and just a bit more than a dribble when the rads are on.
As I put...
It was a Grunfos pump a red one and I replaced it with a Grunfos but is a modern one with some lights on it. £115 the new one was but the old one was £250. I thought that they are the same make but I did think that the quality may not be quite as good but I will give it a go.
Thanks but I can tell your not a plumber, I’m not a plumber as well but I am a tight ba….d so not the immersion has not been left on thanks any way any thoughts may help.
It’s not the pump speed. It’s on low and the stat on the boiler is on very low and the water still flows. Iv tried it fast and slow and it’s the same, so I think that’s not the right answer thanks
Hi can somebody tell me, I’m running an oil boiler 11 years old and a few months ago I noticed little green bits coming out the hot tap, and the hot water was taking longer to heat up, how ever the rads wear fine.
How ever I changed the pump because the old one was making a bit of noise.
That...
