Measuring Radiators to Size a Steam Boiler
Sizing Radiation for Residential Steam Boilers | ||
Measuring Radiation to Determine Sq. Ft of Steam Required
- Measure the heigth of the radiator. This is measured from the floor not the bottom of the radiator.
- Count the number of columns or turbes of the radiator
- Count the number of sections that make up the length of the radiator
- Using the below charts enter the left column to the heigth of the radiator. If between two heigths go the taller number
- Get the multiplier for each section going to the right to the column that has the correct number of columns or tubes per section
- Multiply the number of sections by the proper multiplier for each radiator
- Add up all the radiators and look at steam boiler literature of your choice. Choose the boiler closest to the calculation results
