I would like to share with you some info I discovered while considering buying an Eco Boilier from New Horizon Corp out of Sutton West Virginia. (www.newhorizoncorp.com). The units are advertised as UL certified with Omni Test Labs out of Portland Oregon, so that you can have them installed in certain configurations according to Codes. THIS IS FALSE! The UL certification paperwork was started but never finished therefore if you install the stove and get Code Enforcement to inspect you will be required to take the stove out (depending on your set-up). Some homeowner's insurance will not cover any damage done to your home if the unit isn't properly UL certified also.
