Insulation & comfort
Room Heating Calculator
Your measurements : area, height, planning assumption. Your estimate : estimated power, btu per hour, volume.
How the calculation works
Room Heating Calculator
Area × Height × Planning assumptionBefore you order
- This is a rough planning estimate. Choose the W/m³ assumption for your situation; climate, insulation, air leakage and glazing can change the load. A professional heat-loss or cooling-load calculation is needed for final equipment selection.
