Hello,
I'd like to thank you for your advice to run the boiler at the lowest temperature possible dangermouse46, I observed the boiler when it was doing just the attic zone and it hardly cycled, the boiler went up to 65 degrees and stayed around there and went up to 70 for a while before cutting off. This took about 5 minutes by which time the attic room was quite warm.
What I have done in the attic is placed a fan under the heater, in this way the boiler quickly gets the room up to temperature and spends most of it's time in off state. The attic gets up to 18.5 degrees in 24 minutes with an outside temperature of 7 degrees and flow temperature of 60 degrees.
The boiler is now set at 60 degrees due to the milder weather.
Thank you to all.
