Thanks Riley.
Looks like I'm left to consider options 1 and 4 then (as vaillant replaced the controls last week)
Hi guys,
Just thought I'd follow up.
Vaillant came out today and replaced the pump in the boiler. They said it was fine but would do it for free as a precaution. Unfortunately the rads are still not getting hot!
That leaves 2 issues - rads piped wrong or poor circulation. I think it's the latter because some of the rads have been piped correctly and none of them are getting hot (even the ones piped correctly).
Now I'm trying to find out who's fault this is. The first plumber ran the pipe work but the second plumber commissioned the boiler. Is it correct to assume that the person commissioning the boiler should have checked the heating before confirming it was ok to put carpets down?
In terms of my options I really don't want to rip all carpets and floorboards up and digging out the chases. Is it worth doing a power flush first? How effective are they normally? I'm hoping that because the first rad in the circuit is not getting hot that the blockage is early on in the circuit.
What would you guys do in my situation please?
Thanks
So would the person commissioning the boiler not check that the radiators pumped out heat please? Plumber 2 fitted the towel rails and they're not getting hot either.
Thanks guys. I really appreciate your help as the house renovation has been so stressful and this is topping it off! Especially considering
Yes I have a magna clean but none of these particles are being trapped. The water samples are all clear - it's just when I took the bleed valve off that I noticed all of these debris particles coming out!
Do you think it's worth asking the radiator company to pay for the power flush?
We then tricked the boiler when it was heating hot water to heat the rads instead (at 70 degrees with burner on max) by manually opening the motorised zone valve. All of the radiators (bar a couple that had dodgy valves which we've now fixed) and all the rads were roasting. So the pipe work and rads are fine.
