Field notes
The form combines a provincial-capital location with home-specific inputs, including insulation, dwelling exposure and heated area. Users can add an altitude adjustment, which the page describes as an estimate, and edit energy prices and system efficiencies. Its annual comparison explicitly excludes maintenance, installation and equipment costs; the page also says its October 2026 price figures may include unverified estimates that should be checked with suppliers.
