Luckily, I live in a city where furnaces aren't needed, but one of the conditions when we were looking for a house was that the water heater had to be solar powered. It is so much safer and cheaper. Our house is also well insulated so it stays a good temperature in summer and winter.

One precaution we did go to was to install smoke alarms. I do have a fear of waking up in the middle of the night and the house is on fire, so alarms are GOOD!
