Our Efﬁciency is Guaranteed

Boiler Comparison Guide

Favorable or superior operating efﬁciencies are frequently reported for all types of boiler, particularly in advertising and promotional materials. Most often, these claims are based on factory laboratory tests.

Bryan ﬂexible water tube steel boilers achieve 86% efﬁciency in operation on actual job sites with normal 140° - 160°F return water temperature.

It should be noted that differences in efﬁciency will always occur between water boilers and steam boilers or gas-ﬁred boilers and oil-ﬁred boilers.

For instance, a Bryan oil-ﬁred hot water boiler can be expected to operate in the 85% to 86% range, and a forced draft gas hot water model in the 85% range. Again, these are on-the-job efﬁciencies rather than factory laboratory results.

The Bryan ﬂexible water tube steel boiler is offered in ratings from 6 to 500 hp. This wide selection also helps promote higher efﬁciency by allowing you to select a boiler to match your requirements more closely.

Versatility

Multi-boiler installations and expansion. Because Bryan ﬂexible water tube boilers are available in capacities from 6 to 500 hp, they are well-suited for multi-unit installations.

When more than one boiler is used — whether due to expansion or in an original installation — Bryan can supply a lead/lag demand analyzer system that

protects efﬁciency by enabling the owner to sequence only those boilers required to meet the current load demand.

Fuel and ﬁring options. Bryan ﬂexible water tube boilers are offered with either forced draft or atmospheric gas ﬁring. Either mode is available for use on multiple fuels; natural/methane/propane gas and oil or combination gas/oil.

In addition, the optional Bryan Energy Selector provides oil and/or gas ﬁring or alternate electric power at the ﬂip of a switch. This versatile feature is not available in cast iron or ﬁretube boilers.

Bryan’s Energy Selector lets user choose gas, oil or electric ﬁring with the ﬂip of a switch.
