Transparent scenario calculator
Turn heater kW into dollars per session.
Change every assumption yourself. No model-specific performance claim is hidden inside the result.
What the calculator assumes
Warm-up is modeled at full heater output. During the session, the estimator uses a 60% full-load-equivalent duty assumption rather than continuous maximum output.
Actual cycling, outdoor temperature, insulation, glass area, ventilation, door openings and user behavior can materially change consumption.
Formula
kWh = kW × (warm-up hours + session hours × 0.60)
cost = kWh × electricity rate
