St. Thomas Geothermal Questions
Is geothermal worth it if I already have natural gas in St. Thomas?
For natural gas homes the payback is longer, so geothermal makes the most economic sense for propane, oil, or electric heat, where the rebates and fuel savings add up fastest.
Do you service existing geothermal systems in Elgin County?
Yes. We service WaterFurnace and other ground-source units across St. Thomas and Elgin County, including loop checks, refrigerant, and annual maintenance.
What loop type works on a St. Thomas area property?
Larger rural lots around St. Thomas suit a horizontal loop field in shallow trenches, while tighter in-town lots may need vertical boreholes. We confirm soil and lot conditions at the site visit before recommending the loop.
How is the geothermal system sized to my St. Thomas home?
We run a full heat-load calculation on your home's size, insulation, and windows, then match the WaterFurnace unit and loop length to that load. Correct sizing is what keeps the system efficient and comfortable year round.
Can geothermal fully replace my propane or oil heating?
Yes. A correctly sized unit carries the entire heating load off the constant earth temperature, so St. Thomas homes can drop the propane tank or oil deliveries for good while gaining cooling from the same system.
