PB Heat Boilers

Overview

The PB HEAT 14359 is a cast iron, oil-fired hot water boiler from the Peerless WBV-e Series, designed for residential natural draft (chimney) venting applications. Rated at 87.5% AFUE, it delivers a DOE heating capacity range of 75 to 126 MBH and a Net IBR Rating of 65 to 110 MBH, making it well suited for moderate to larger residential heating loads. The unit ships less burner, so a compatible flame retention burner, such as a Carlin, Riello, or Beckett model, must be supplied and installed separately. It includes a Taco circulator and Hydrostat reset control with low water cut-off. Licensed HVAC technicians and plumbers typically perform installation. The 14359 is intended for residential hot water heating systems using natural draft venting through an 8-inch by 8-inch masonry chimney with a minimum 15-foot height. The boiler is a floor-mount unit measuring 22.125 inches in length, 27.875 inches in width, and 35 inches in height. It accepts firing rates from 0.6 to 1.05 GPH, giving installers flexibility across eight firing rates depending on heat load requirements. The convertible rear-to-top flue outlet adds layout flexibility during installation. Compatible burner types listed by the manufacturer include Carlin, Riello, and Beckett flame retention units.
