Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Connected power = heater count × power per heater. Average power applies the duty cycle. Energy = average power × operating time. Cost = energy × electricity price.
FAQ
Patio Heater Running Cost Calculator questions
What does duty cycle mean?+
It is the share of operating time that heaters run at full power. Thermostats or staged controls may reduce average energy use.
Do infrared heaters use less electricity at the same power?+
Two heaters with the same electrical input consume the same energy while on, though comfort and heat targeting may differ.
Does this include propane patio heaters?+
No. The inputs and results are for electric heaters rated in kilowatts.
