Hi all,
Ok, I'm a dimbo on these things, but I want to avoid the usual lazy forum question 'my boiler's broke how do I fix', so I've tried to detail as much as I can below.
My plumber's down with flu at the moment, so it might be next week before he can look and I'd kick myself if it was something stupid.
Here's the situation:
- Hot water is absolutely fine
- Radiators are lukewarm
- Pump seems to be working (can feel it vibrating if I put my hand on it)
Setup:
- Oil-based boiler - Greenstar Heatslave II External 25/32
- Unvented Cylinder - Evocyl AIR (300L)
- Newish radiators (maybe 4 years old)
Any thoughts/tips most welcome - I've read some posts that talk about air blockage, I don't really know how to 'unblock' this if this is a suspect!
As you can see from photos below, radiators are definitely on, just not very hot and heat centred at the top (although this could just be lack of flow)
You can see in photo below, the water coming into the cylinder is red hot and the pump appears fine (where it says 56.3C)
As per below all the pipes at this stage seem to be hot and working fine, it just becomes lukewarm once it goes into the house:
