What type of venting or exhaust is required?
This depends on the type/model of tankless water heater desired. Some have a power venting system and are ran to the a side wall. (In warmer climates, outdoor installation is also possible and these usually need to exhaust components.) Others are “direct vent”. All of our direct-vent models exit via the side wall in a horizontal configuration. The recent trend in the gas fired tankless industry is to exit horizontally. This eliminates complicated weather hoods and shields that prevent leakage around shingles as well as the necessity of a condensation trap. Horizontally vented heaters have an exit pipe that slopes slightly down-hill which allows normal condensation to drip away from the unit. (As explained and as per most manufacturers today our heaters cannot be vented through the roof.) If our website does not answer your questions, please contact us for more information on venting types and specific requirements.
