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 Low Fire High Fire 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. Trouble-Free Operation There’s nothing more irritating than a boiler that sputters out when you need it most. That’s why Efficiency+ has an integrated boiler control that ensures safe burner operation and prevents nuisance flame-failures. High Efficiency, Gas Fired Heating Boiler 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™ tile to reduce unit weight by 25% as compared to conventional cast refractory materials. Loch-Heat tile also increases efficiency by reflecting heat back into the combustion chamber rather than absorbing it. 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.
