In 1986, Power-Fin® redefined the water heating industry with space-saving design, groundbreaking efficiency and venting flexibility. Twenty years later, we’re again raising the standard for innovation, reliability and LEED-conscious design.

The latest generation of Power-Fin offers expanded burner modulation and the advanced SMART SYSTEM™ operating control, including a built-in cascading sequencer for up to eight boilers.

In today’s market, sophisticated, versatile control systems and equipment that meets “green building” criteria are increasingly in demand. Power-Fin boilers continue to evolve, with new “Built-in Advantages” from Lochinvar.

Infinite Modulation

With thermal efficiencies up to 87%, Power-Fin boilers feature infinitely modulating burner firing rates (turndown), precisely matching the firing rate to heating load requirements. The result is better overall efficiency and less cycling.

Power-Fin boilers may be specified as either 5:1 turndown (502 - 2001), 2:1 turndown (1501 - 2001), or 100% ON/OFF (502 - 1302). With 5:1 turndown the burner fires as low as 20% of maximum input when demand is lowest and increases the firing rate up to 100% as demand increases. Models with 2:1 turndown modulate from 50% to 100% of maximum input.

Gasketless Heat Exchanger

The Power-Fin heat exchanger features an array of 20 or 24 copper-finned tubes surrounding the burner for maximum heat transfer. Lochinvar also pioneered the “gasketless” heat exchanger, which eliminates the use of O-rings and gaskets. Because of the time-proven reliability of this design, the Power-Fin heat exchanger is backed by a 10-year limited warranty.

The vertical heat exchanger also makes Power-Fin compact and easy to handle, install and service. All access for installation or service is through the front or back, and multiple units can line up side-by-side with zero clearance to combustibles.
