Hi,
I have a Grant Vortex 36kw Combi-boiler producing hot tap water on one circuit and centrally heating the rads on the other.
Everything is working perfectly except we have noticed it is taking longer to heat the hall way. The bedrooms are fine.
Heating comes on automatically 1730 and cuts out 2230 as programmed. It is taking two hours longer to get to 20 deg C in the hall way than it did a couple weeks ago. Ambient outdoor temp is similar.
System has been flushed and air bled out and radiators seem as hot as they always were when on, as far as I can tell.
Anyone any ideas ?
Thanks
