Stewart Brown spent 29 years as a researcher at Ontario Hydro, so he knew a DX geothermal system at his home in Halton Hills would save him money when compared to his electric baseboard heating. It did. “I created these spreadsheets showing consumption dropped by two thirds, from about 24,000 kWh per season to about 8,000,” says Brown.
He is now saving between $2200 and $2400 each year. “He also got air conditioning, which he didn’t have before,” says Al Davies, his installer. Al put in a six-ton DX system.
