17-0410 v3.1/Backup Energy - Hydronic Tie-In 3.x

QUESTION

Our project (residential) is looking to use a high efficiency wood stove (84%) which meets all emissions criteria and has a hydronic loop which recirculates fluid through the heating element and back into a hot water tank for distribution to hydronic space heating, or domestic hot water storage. The project is located in L2 transect and would only rely on this technology during extended power outages. Is this technology acceptable, and compliant with the ornamental fireplace guidelines while still achieving homeowner needs for backup energy?

ANSWER

Including a hydronic loop to add energy benefit is acceptable for backup energy when the fireplace in question is allowed under another exception and is not the primary heat source.
