Lochinvar E B N 150 Fascicule
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+ 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.

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.

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.
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.
