Energy saving tip number 2

Replace your oil or gas-powered furnace with a heat pump…
A heat pump runs on electricity and works like an air-conditioner, but in reverse. An air-conditioner takes heat from inside and moves it outside so that it is cooler inside. A heat pump does the reverse, it takes heat from outside and moves it inside to make it warmer inside.
Even if it is below freezing outside, a heat pump can take energy from the outside air and move it inside to make it warmer. This is much more efficient than burning fuel to make heat and it doesn’t burn any oil or gas. It only uses electricity, which can be generated from just about any source.
A heat pump is relatively inexpensive, easy to install and usually pays for itself in about a year or two.

It's kind of counterintuitive to think that a heater can cool the air, but once you understand that it's not actually heating anything (much), it's just moving the heat from one place to another.
@Pat Yup, using that kinda fluid to move the temperature between inside and outside. It goes both ways!
@Pat It paid for itself in less than a year for me already. :D I love heatpumps/airconditioners (to me they're both the same as one device can effectively both heat and cool).
