Frequently Asked Questions — Peerless Commercial Steam Boiler Installation
What is the Peerless 211A Series commercial steam boiler?
The Peerless 211A Series is a cast-iron commercial steam boiler designed for large residential and commercial applications — apartment buildings, schools, churches, and industrial facilities. It is available in multiple section configurations to match the steam load of the building.
How is a commercial steam boiler sized?
Commercial steam boilers are sized based on connected radiation load (EDR — equivalent direct radiation), not square footage. D's Air & Heating, Inc. performs a proper EDR survey of the existing radiation to ensure the new boiler is correctly sized. An oversized steam boiler causes water hammer, wet steam, and wasted fuel.
