Series 8H/8HE
  • Atmospheric Vent
  • Cast Iron Gas Fired Commercial Water Boiler
  • 252 – 505 MBH input
  • 80–82% Thermal Efficiency
  • 30 or 50 psi
  • Modular/Multiple Boiler Applications


The Series 8H/8HE boiler is ideal for large residential and light commercial water boiler applications. The compact design makes it easy to transport through a standard 36-inch doorway and the small footprint means it will fit into most boiler rooms. The 8H/8HE has standard safety features such as a blocked vent switch and a flame rollout switch which automatically shuts down the boiler if the chimney or flue passages become restricted. Other manufacturers charge extra for these safety controls.

Efficient Space Heating with the Modular/Multiple Boiler Concept

Modular/Multiple boiler systems put the efficiency, cost and service advantages of compact gas boilers to work in heating application where a single commercial boiler would not be efficient.

The systems connect any number of compact, self-contained gas boilers together and stage fire them to efficiently meet heating loads on demand.

Simple controls and simple design means the boiler will be easy to service and maintain.
