We have been using propane to heat our home mainly for the last 3 years. I loathe it, it is high-priced and there is nothing that I can do about it. As winter approaches, I am usually very annoyed with being trapped into buying propane, as I think many people in the U.S. feel. We do also use some corn to heat, and we like that, but it in no way is capable of our whole heating load.
When I first heard of the ductless heat pump, I was very interested to learn more. I have always known how well heat pumps work. They are efficient and with electricity not climbing as much as propane it is a good value. 30 years ago I had a good a good friend who was learning heat pump technology, since he was a serviceman for a heating and AC company. I can still remember how impressed he was with heat pump technology.
Nothing has changed since then, except that fuel prices have continued to increase. Heat pumps are still a exceptionally viable and practical heating source. Energy conservation is still important, maybe even more important, I think Heat pumps are here to stay. Here are some of the advantages as I see them.
Since central heating and cooling systems do not rely on openings like windows and fireplace flues, these openings can be made more air tight when they are closed. This does not mean that there has to be a lack of fresh air in the house. Central systems can include a piece of equipment known as an air-to-air heat exchanger, which brings a flow of fresh, outdoor air into the home without losing energy.
When considering electric heating always remember that a fossil-fuelled power plant may only deliver 4 units of electrical energy for every 10 units of fuel energy released. Even when you use a 100% efficient electric heater, the amount of fuel needed to make the amount of heat needed, is more than if the fuel was burned in a furnace or boiler at the building being heated. The amount of electric that is lost by substation transformers and transmission lines is almost 2/3 thirds of what was initially produced at the power plant.
Electric heating can be good in some cases, but in many situations it is not a responsible use of our resources. Also, do not believe the claims that one electric resistance heater is more efficient than any other. One kilowatt of electricity will always convert to 3415 BTU’s of heat
