Due to its low efficiency and high emissions, an installer is asked to replace the outdoor wood-fired furnace shown in Figure 1, with a new cordwood gasification boiler.
The new boiler has a rated output of 150,000 Btu/h. The outdoor furnace is located about 100 feet from the indoor mechanical room. Two runs of 1” PEX connect the outdoor furnace with the remainder of the system. Due to existing landscaping, the installer plans to reuse the existing underground piping.
