The solar closets et al, are good retrofits to existing homes with some
added insulation points, as: triple glazing or double with low "e" glass,
make the house as air tight as possible, draught proof the windows and
doors, put over 1 foot insulation in the loft, install porches on outside
doors, etc.

The more a house is insulated and air-tight the less you need to generate
heat.



Humm. What do you do with the breeze in the hours after a curry
consumption?..

open the windows, or rely on the heat recovery system, which is virtually
mandatory in a air tight house.
