Here in glorious sunny Kerry my good lady and I were discussing other peoples power bills whilst consuming our late breakfast.
Pretty similar to the last post we are trying a couple of approaches in our new house:
South facing double hight sunspace outside the thermal/airtight envelope of the building with openable windows at the bottom and top so it works as a solar chimney. There are three victorian style clothes hangers mounted from the ceiling. The heat dump radiator is also in here.
A large cupboard with internal clothes shelves that has an extract vent for the MVHR unit fitted in it. The water evaporated from the clothes condenses in the MVHR HX.
Not sure which will work best but we will find out soon.
