- First, my home heating system is essentially a oil-fired hot water heater
- (except the hot water heats my house not a shower) and it is rated as 87%
- efficient. Higher efficiency is available. I see no reason why an oil
- fired hot water heater should be only 20-30% efficient.
-
- Second, while the electric heater is 100% efficient at converting the
- electricity you pay for into heat, the power plant is only about 40%
- efficient at generating the electricity and getting it to you.
-
- This is reflected in the higher price of electricity compared to oil.

- (consider gas, if possible, too)
