Going to have to come back to this in a bit as have a flood (excuse the pun) of other lifey things need sorting, but wanted to thank @everyone for their replies and advice so far - it is really appreciated.
Thanks @MeldrewsMate - no towel rad in the circuit, just the Bathroom Rad first in line which gets piping hot with both CH and HW demand irrespective of other results/rads.
Should I try closing this Rad once pump running as a test?
Does the water pipe (cold feed) from the loft mounted F&E tank...
CH & HW Demand Test
HW Cylinder set to 70 degrees (was 60 prev.)
HW & CH turned ON at controls.
- Diverter Valve moves to M.
- At 22 mins boiler Burner still ON.
- Run HW tap: water is warm/hot but not scolding hot.
- Rads behaving as per prev. tests i.e. some tepid, some hotter,
- Entrance...
@Johntheo5
- Pump replaced approx 1 year ago because (very) old Grundfos pump spindle was getting jammed frequently.
- CH was fairly lacklustre prior to pump change but did essentially operate and boiler/burner remained on; after new pump install CH never on long enough to properly gauge...
@Johntheo5 - thanks for staying with this and apologies for belated response - have been away for a few days.
Vent Pipe Tests
Pre-testing: Vent pipe that runs over cold water tank is dry as a bone, inside pipe and externally, indicating that no water has passed through recently.
- CH ON
- No...

Thanks @Johntheo5 - as @MickyP10 says this was a good spot.
For various reasons we won't get into I have a deep seated, some may even say conspiratorially cynical, aversion and attitude to anything labelled or promoted as 'Eco' - so I can definitively confirm I've never used this setting and...
@gas112 - It does, however so far I've been killing the CH v shortly after the Boiler Burner Indicator goes out because:
a) I was concerned about causing damage
b) I don't know what I'm doing
c) wife told me to even though she also doesn't know what she's doing
As mentioned, I'll try keeping...
Thanks @Johntheo5
Pump is Archergas - please see attached (
Running on II (Two) Speed.
Going to try the continuous 2 hour CH run later this evening and report back.
@numpty1
Thanks - that's definitely something I can try (I'll stick a Columbo film on whilst I wait).
A couple of dumb follow-up queries (sorry):
- Do you mean the stat/dial on the Boiler?
- The Worcester Bosch manual states the temp range is approx 35 - 82 Degrees C but the dial isn't...
Thanks v much for replies:
@Hugh Jaleak
- When system was drained the water was fairly clear, and certainly not discoloured/odd enough for us to take note
@Johntheo5
- Boiler doesn’t exactly reset:
- Burner Indicator (Green light) comes ON when CH turned on
- After approx 15 mins, Burner...
Hi all,
Firstly apologies if this is something already covered; I did search the forum prior but couldn't find anything specific that replicates the issues I'm having.
System:
Gravity Fed, cold header tank in loft.
Boiler: Worcester Bosh Greenstar 15Ri
Pump: Archergas 15-60/130 – fitted...
