An EDR+ 3000 from Fulton Heating Solutions, Pulaski, N.Y., surpassed 155,000 ignition cycles in laboratory testing – running through more than 20 years of ignition events. The company believes that this durability testing sets a new benchmark for boiler reliability and durability validation. Part of its Endura+ condensing boiler line, the Model 3000 can be used for pharmaceutical and custom process applications as well as facility heating and cooling.

Conditions during the testing cycle included sealed combustion to vary inlet-air temperature and connection to a pump skid to create variances in water temperature. Gas pressure also was modulated to create a range of supply pressures. In aggregate, the regularly altered testing variables simulated a range of installation environments.
