Taking Comfort and Efficiency to the Next Level

An Investment You’ll Feel Right at Home with

Heating your home or business is one of the biggest investments you’ll ever make…and you deserve a heating system that delivers unmatched comfort, dependability and energy savings, year after year. That’s why Efficiency+ from Lochinvar is the smart choice for heating.

Efficiency+, with inputs ranging from 150,000 to 300,000 Btu/hr, more than lives up to its name, with an outstanding 84% AFUE. It has two- stage firing that saves fuel by closely matching heat output to system demand, maximizing operating efficiency.

Two-Stage Firing

During the majority of the heating season less than full boiler input is required to satisfy a heat load. For this reason Lochinvar has developed a two-stage firing system. Two-stage firing — standard equipment on all Efficiency+ boilers —provides dramatic fuel savings by reducing heat output 50%. That means when outdoor temperatures become warmer, the boiler will use less fuel to maintain comfortable indoor temperatures.

Stage 1 Stage 2

With standard two-stage firing, Efficiency+ reduces gas consumption.

On colder days the boiler fires at full input.

In warmer conditions Efficiency+ reduces heat output to save energy and reduce cycling.

Efficiency+ is also designed to operate on low gas pressure — a key consideration in regions where natural gas supply pressure is in the 4 - 5 inch range.

Space-Saving Design

With Efficiency+, you get high efficiency heating in a surprisingly compact unit. It fits easily where other boilers won’t.

The Efficiency+ is remarkably light because of its copper tube heat exchanger and other design breakthroughs. For example, Efficiency+ uses Loch-Heat™

Efficiency+ has an 84% thermal efficiency rating, which means 84 cents out of every fuel dollar are used to create heat. Other efficiency ratings can be misleading and result in artificially high ratings.
