About this calculator

Calculate the estimated monthly cost to heat a greenhouse based on size, insulation quality, target temperature difference, and fuel type.

Frequently Asked Questions

How is insulation quality factored in?

Better insulation reduces heat loss, lowering the effective heating demand and cost. The slider adjusts a multiplier applied to base heat loss.

Can I use this for a heated hoop house?

Yes, this calculator works for any small enclosed growing structure where you can estimate floor area and desired temperature difference.

Why do different fuels use different units?

Electricity is billed per kWh, propane per gallon, and natural gas per therm, each with different BTU content, so conversions are applied automatically.
