Boilers  
Energy Efficient, Cost Effective Boilers  
Lochinvar first introduced Copper-Fin technology to the boiler  
industry some 50 years ago. Since then, we’ve continued to refine  
and perfect it - adding advanced fan-assisted combustion, hot  
surface ignition, a unique gasketless copper finned tube heat  
exchanger and highly efficient insulating materials.  
Installation Flexibility and Cost-Savings  
With compact sizes that use less floor space than ever before,  
all Copper-Fin units are narrow enough to fit through a standard  
36” doorway – an advantage most commercial boilers can’t provide.  
Plus, thanks to special insulating materials, Copper-Fin units require  
only 3” clearance from combustible walls. What’s more, our  
Stack Frame allows you to install two units in the area  
normally required for one. This makes it easier to fit multiple  
Copper-Fin boilers into cramped mechanical rooms. And you  
can even use a smaller diameter vent stack - up to 8” smaller than  
typically required for comparable atmospheric boilers - so it saves  
money as well as valuable mechanical room space.  
Enhanced to Provide Performance and Serviceability  
Our enhanced Copper-Fin models offer the same reliable operation, and  
feature a more service friendly design. The down stream test valves and  
referenced gas valves are now in the upper deck for easier access, and  
the electrical and BMS connections have been repositioned to the front  
of the unit for easier installation.  
Unique Copper-Fin Heat Exchanger  
The Lochinvar Copper-Fin boiler design uses a two  
pass heat exchanger. Water is circulated through  
a row of highly-efficient, finned copper tubes.  
The high rate of water flow creates a  
scouring action that prevents sediment  
and lime-scale buildup, common  
in conventional boilers, and  
The gas valves, which are referenced to the sealed combustion chamber,  
improve operational performance by monitoring the pressure in the  
sealed combustion chamber and adjusting gas flow to maintain the  
optimum air/fuel mixture. And the built-in air inlet filter reduces  
maintenance and improves performance by trapping dust and airborne  
particulates that can foul the burners and blowers. With dual sight  
glasses (one on each end), you can easily monitor burner performance  
and flame characteristics throughout the entire combustion chamber.  
the finned copper tubes  
allow maximum heat  
transfer efficiency.  
To create this special  
heat transfer capability,  
Lochinvar extrudes the fins  
The operator interface panel provides two-stage electronic  
temperature control and comprehensive diagnostic status  
without opening the control panel. Its user friendly design  
simplifies service while providing additional diagnostic  
information through a series of LEDs.  
from thick wall copper tubing to  
precise specifications - exactly 7 fins per inch.  
The result is an integrally-finned tube with a heat transfer ratio 9  
times greater than a plain copper tube.  
Heavy-Duty Gasketless Design  
Vent Cost-Savings  
What’s more, advanced casting processes allowed Lochinvar to  
develop a unique one-piece header system. This gasketless design  
provides enhanced reliability, improved durability and optimum  
performance - without the problems or failures common with  
O-rings and gaskets.
