What model firebird? Put a pic up of front with cover off.
Yes pump is spinning.Is hot water pump operating when hot tap opens?
Sorry, not sure about this one?How hot is the heatstore?
Sorry, yes course.......heatstore is hardly hot at all.Heat store is the steel tank on right had side of boiler pumps in front of it.
Should be hot (too hot to keep your hand on comfortably)
It's the tank behind the pumps, it stores hot water to generate your actually hot water.Sorry, not sure about this one?

Have just changed this tonight.....no change.Could be the heat store thermistor.
Not really, the water temp fluctuates, and when I rotate the blender valve backwards and forwards it does get hot for a while. Which is why I was wondering if it was the blender valve?Is the heat store now hot ?
Yes, did that yesterday ran for about 10 minsThe heat store should still get very hot even if blender valve is faulty. Can you switch off the boiler, run off say 20 or 30 liters of HW, shut the HW tap then fire up the boiler and see how long it runs for.
The store feels mildly warm but not hotThe 35kw boiler must have sent 5.53 kwh somewhere, assuming.iit's to the store then that's sufficient to raise 125L from 25C to 65C . Are you sure the store isn't very hot? The only other route for that 5.53kwh is to the CH?
