It goes from 0 to 45 here, heating and cooling probably add up to 15-20% 
of our energy (without insulation). Solar water would save a heap more 
than that.

You must have used a truckload of energy for that bottom 10 degrees 
without insulation and it must have a very effective thermostat unless 
you are saying you rarely need it on now.
