Series 211A Pricing — 2026 D's Air & Heating
Larger boilers = lower cost per BTU. Although larger boilers have higher total project costs, the installed cost per BTU decreases as size increases because labor, controls, permitting, startup, engineering, commissioning, and project management costs are spread across more heating capacity.
