This summer I turned off the circulating electric fan motor on my gas furnace to CONSERVE energy, just like the ads say. But the house smelled stale and the basement musty. Turned on the furnace fan and in a few hours back to normal.
Using the hydro Smart Meter web site, I looked at my hourly/daily/peak/off peak electrical load. The furnace motor uses about half a kilowatt to operate. At the current hydro delivered HST included cost of some 15 cents per kWh, running the fan cost about $650 per year. Plus Toronto Hydro have just asked for another rate increase!
An new technology ECM motor in my not so old furnace would save about 75 % or almost $500. New motors should cost about $700 installed - an ROI of 70%+ or 16 months to get my money back. A better investment than my stocks and bonds.
Do you know a good installer?
By the way if 2 M Ontario homes did this we would save several new nuclear reactors which are planned to cost billions of $.
