Create a preliminary heating load for comparison—not a final equipment design.
Use this as a planning estimate. Verify product labels, local conditions and supplier packaging before buying or applying materials.
Conductive heat loss = exposed surface area × temperature difference × U-value. The result excludes infiltration, wind and ground losses.
SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.
It describes heat transfer through an assembly; lower U-values indicate better insulation.
Real greenhouses also lose heat through air leakage, wind exposure, doors, thermal bridges and the ground.
