Now if only the price of gasoline would make people drive more efficient cars

So how does that work then?

We burn kero for heat, but have an outside boiler and central heating. No smell, no condensation.

Whe i lived in nagano, my girlfriend and i bought an electric blanket, in combination with shared body heat was great. Would wake up in the morning to a balmy indoor temprature of 1 degree celcius.

 

However, this time with no girlfriend nor electric blanket, i am using 3 quilts, a toque, a vivid imagination and a heater set to 14 degrees.

So using electric blankets
Are the dangers just old wives tales?
Or are there real risks?

We've not talked to that many Japanese housebuilders but all the big ones seem to spend a small fortune on sales and promotion. That Sekisui Haim model looks quite good, but its a question of how difficult it is to plan and fit the solar system. The other aspects of the house, airtightness, insulation, all-denka, underfloor heating, etc., can be done by most builders, some of whom will offer you more flexibility and possibly better value. Sekisui reckon 1 in 10 solar houses are theirs, and that is pretty impressive.

 

We've got central heating too, but I bet it will use a lot of kero when the time comes. I've bought a timer switch and I'm going to experiment to see if its cheaper to turn it off overnight. Its on all the time otherwise.

The Sekisui houses are built up with prefabricated steel or wooden frames bolted together so they're pretty earthquake resistant. Then they're well sealed and insulated, and topped off with solar panels. Apparently if you're tight-fisted with your electricity and turn unnecessary appliances and lights off, you can get close to zero grid electricity use for the whole house (on Shikoku anyway. And my goal would be to turn a profit. Obviously.).

 

Certainly the Sekisui salesman is persistent, but he's also exceptionally well informed and actually honest. The overall performance of their houses appears to be superior to other prefab makers, and to all wooden house builders.

 

Finding the right bit of land at the right price is the major problem.
