Field notes

The questionnaire adjusts finished room volume for heat-storing surfaces before estimating traditional electric-heater demand. Its stated planning method uses approximately 1 kW per cubic meter of effective volume, adds 1.2 cubic meters for each square meter of glass or similar uninsulated surface, and applies a 1.5 factor to non-insulated log walls. Budget choices range from under $5K to $20K-plus, with recommendations linked to public manufacturer and retailer specifications.
