Frequently Asked Questions
What is the difference between the PUREFIRE and MI Series?
The PUREFIRE is a condensing boiler with up to 95% AFUE efficiency, covering a wide capacity range from 399,000 to 4,000,000 BTU. The MI Series is a cast-iron atmospheric boiler at approximately 82% AFUE, covering 105,000 to 280,000 BTU. The PUREFIRE is the choice when efficiency is the priority; the MI Series is the choice when simplicity, serviceability, and proven cast-iron durability are the priority.
Is the PUREFIRE worth the higher upfront cost?
For buildings with high heating loads and high gas costs, the PUREFIRE's efficiency advantage can pay back the premium over time. For smaller buildings or buildings with lower heating hours, the MI or WV Series often provides better value. D's Air & Heating will calculate the payback period for your specific building during the estimate.
What is the WV Series best for?
The WV Series covers 210,000 to 560,000 BTU and is the standard replacement for mid-size commercial buildings — apartment buildings with 6–15 units, small office buildings, and light commercial facilities. It uses the same cast-iron construction as the MI Series with a larger capacity range.
Can I replace an atmospheric boiler with a PUREFIRE?
Yes, but it requires changes to the venting system. The PUREFIRE uses PVC venting (condensing exhaust) rather than the B-vent or chimney flue used by atmospheric boilers. D's Air & Heating will assess the venting requirements during the estimate and include any necessary venting modifications in the installed price.
Peerless commercial hot water boilers are manufactured by PB Heat and are available in three series covering a wide range of commercial applications. The PUREFIRE condensing series is the high-efficiency choice for buildings where fuel savings justify the higher upfront cost. The MI and WV Series are cast-iron atmospheric boilers that offer proven reliability, easy serviceability, and competitive installed pricing.
