Sec. 18-121. - Purpose.#

The town recognizes and finds that although outdoor hydronic heaters or outdoor wood boilers (hereafter collectively referred to as "OHH") may represent an economical alternative to conventional heating systems, these systems shall not be used as the primary source of heat and hot water and should not be located or used in such a manner as to compromise the health, safety and welfare of the citizens of the Town of Tiverton. Such outdoor furnaces can cause harmful emissions, offensive odors, smoke, soot, fumes, ash and other conditions that may constitute a public nuisance.
