Elite FT Commercial Boiler

High Efficiency

up to
thermal efficiency

lower energy costs:
up to 96.7% of the gas consumed by the Elite FT 399BTU boiler is converted into heat, compared to a mid efficiency system where up to 40% of the heat can be lost through the chimney


5 to 1
Turndown Ratio

modulating technology matches
fuel consumption to demand to
provide high system efficiency even
during low load conditions


Greater Turndown
greater turndown allows the Elite FT
to modulate at lower firing rates which reduces
short cycling, conserves energy
and improves component reliability
