Hi guys,
thanks for the feedback and questions.
Yeah, that's my fear all a long - in that it's a design flaw of the house rather than an easy fix as I was hoping for.
Let me answer some questions first.
1)No, there's no rad in the hall at the moment. It's heated by UFH and is zoned.
2)Yes the door between the kitchen/hall is sufficient at keeping the draughts out, however the kids are getting a bit miffed with the constant "will ya keeping that door shut!?"
3)The attic is well away from the stairs and is insulated - the house would be well insulated
4)The stair area is large
The key for me is that during the night when the stove has burned out and the heat on, the house has a constant temperature throughout in the morning, so I'm led to believe that everything is working as designed.
If I expand on the house design a little more, there's a 'void' in the living room up to the first floor. Whats happening - i believe is, there's a convection air current occurring on which it is sucking the air out of the hall and 'dumping in the living room. When we sit in a certain area there's a cold draught coming down from the void. What I was hoping for was to increase the heat in the hall so that there's a certain equilibrium attained, thus alleviating some of the problem.
I thought energy efficient EH were very cost effective. Somewhere between 200 and 400w of power.
