A six-page brochure highlights the thermal and combustion efficiencies of the manufacturer's new 28HE Series boilers. The literature features information on the boiler's design and construction, including the unit's extra-thick insulated metal jacket and heat transfer rods with efficiencies of up to 86 percent for oil and 83 percent for gas, the company says. Engineering diagrams and dimension and specification charts provide sizing and selection information. Specifications are provided for 15 basic sizes.
