Patterson Kelley Boilers Copper Finned Tube  Boilers

P-K Thermific boilers have been engineered to provide the greatest output within a small, compact footprint. This makes P-K the ideal replacement boiler for large boilers that need replaced. Even the largest model can be moved through a 30" doorway.  

Small and efficient: just two of the many reasons why we are proud to represent Patterson-Kelley. 

Complete Packaged Design: the P-K Thermific boiler is completely packaged, including burner and controls, pre-wired and mounted in a totally enclosed cabinet. It is readily installed and requires only five connections: gas, electric, vent (standard insulated or double wall "b" vent) and water supply with return. 

Quiet Operation: the P-K Thermific boiler operates quietly and below OSHA standards. Examples of applications can be found inside hospitals, libraries, churches, nursing homes, penthouse equipment rooms, schools and other commercial real estate applications.

• Efficient - The P-K Modu-Fire Boiler - 5 to 1 turndown and up to 88% efficiency.
• Easy to Vent -  The sealed combustion feature Allows for multiple venting options, Conventional, through wall, direst Vent/Sealed, Vertical Vent/Sealed, Outdoor.
• Easy to Install - Even the largest P-K unit, at 2,000,000 BTU's, fits through a 30” doorway. Vents through a standard B vent keeping installation costs to a minimum.
