The Peerless MI Series consists of seven packaged hot water boilers offering up to 80.2 percent AFUE. These cast iron boilers are designed for natural draft use with a conventional chimney, and feature a low-profile design for installation in low clearance areas such as garages, closets or attics.
Models in this series have a heating capacity ranging from 58 to 211 MBH and are available in either natural or LP gas. Additional components of the MI Series include a Taco circulator, a flame rollout safety shutoff switch, and a vent safety shutoff switch, and the option of either a standing pilot or intermittent ignition.
In addition, standard Honeywell controls are included with the goal of making maintenance for this unit easier for contractors and less expensive for homeowners.

"Mechanical Engineer"
I've got to believe that the majority of complaints on this site are the result of bad installation / application. Having specified and personally installed just about every brand of Boiler listed on this site, I am a huge fan of Peerless! Putting a "Super, high efficiency yada yada yada..." boiler in an ordinarily constructed older home is just asking for trouble! When a consumer picks a heating system on efficiency alone and garners technical expertise from google well... There you have it. application & installation rule!!!

"Peerless NG Boiler, MI-04 SV"
Recently bought a Peerless NG Boiler, MI-04, 105,000 BTU along with a Pprtner indirect HW heater. This replaced an old boiler with a coil. The indirect water heater is actually a "Super Stor" (not made by Peerless) although none of the Peerless literature states this. My only complaint so far is that you need to run the faucets (kitchen, bath, etc.) for about 45 seconds for the water to get hot. The wait time was under 10 seconds with my old system. No idea why.
