The ENDURA XE is a condensing firetube hydronic boiler with efficiency up to 99% and up to 15:1 turndown. Fulton states it cuts fossil fuel use by 15% and NOx emissions by 80% compared with conventional boilers.
Flame-by-Wire combustion with real-time O2 compensation simplifies start-up. The Type 439 stainless heat exchanger sits in a large water volume, which Fulton says removes the need for buffer tanks and primary-secondary piping, and the boiler is designed for variable primary flow.
