Sustainability Post #15 — Comparing Fuels

I often get asked to compare different heating systems, using different fuels, at various efficiencies. This is often done in search of the ‘Magic Bullet’ to save lots of money on home heating. The latest miracle cure is the geothermal heat pump (actually, a ground source heat pump). Now, there is no magic bullet, but it is possible that a change in heating source could save you money. Before you do that though, you should do everything you can to lower the heat loss of the house.

If you want compare fuels for yourself, I have created a web page which you can input you possible choices, their efficiencies (note: COP times 100% gives efficiency for heat pumps), and current or expected prices. Hit the ‘compute’ button, and you get the prices for a uniform Million BTUs. Don’t worry if you don’t understand what that means, just look at the prices and pick the lowest one. The URL is:
