Southern Oregon deep freeze— perfect for solar home


It's unusually COLD in southern Oregon and has been for several days. This morning was just 8 degrees F and now, close to 11 a.m. under blues skies and brilliant sun, it's still only 18. But the solar water panels on our roof have kicked in to heat the water circulating in the hot water tank to 100. Before long, it will will rise to around 150, as it did yesterday, and I'll throw a load of clothes into the washer and fire up the dishwasher. It'll also be time for a long hot shower because for the next 12 hours or so, we'll have free hot water. Thanks to our modest passive solar home, built in the early 1980's, we'll also have free heat as waves rise out of the simple solarium and sun streams through south-facing windows in a living room addition built in 1994. PK took pains all those years ago to include every energy-saving trick we could afford including:
  • a clean-burning woodstove
  • 10-inch thick insulation
  • whole-house fan, which is primarily responsible for summer cooling
  • ceiling fans
  • double-door entrances
  • a solarium that heats the house on cold sunny days, doubles as greenhouse in the spring, and serves as a winter clothes dryer
  • orienting the house to face south
  • double-paned woodframe windows
Everything still works, and summer or winter, nary a sunny day goes by without thanking our sun-smart 2.300 sq. ft. home—warm in the winter and cool in the summer for an average energy bill of around $100 a month, year-round. (In addition to a tiny woodstove in the living room, we use a natural gas stove in the center of the house for heating, and also cook with natural gas.) Next up, perhaps, solar-electric panels.
