A transparent scenario calculator for electric traditional saunas. Change every assumption yourself.
Warm-up is modeled at full heater output. During the session, the estimator uses a 60% full-load-equivalent duty assumption rather than assuming the heater runs continuously at maximum output.
Actual thermostat cycling, outdoor temperature, insulation, glass area, ventilation, door openings and user behavior can materially change consumption.
