Tankless gas water heater question
Are there any tankless gas water heater models that can be vented vertical with B Vent
All the 80% ones that I know of ask for the stainless....0
what does the manufacture say?"The bitter taste of a poor install lasts far longer than the JOY of the lowest price"0
I checked with Rinnai, Navien, Bosch and Purepro (Bosch private label models) non are for venting into Bvent piping.
Just checking if anyone knows of a brand that can be vented that way. Most likely none are vented this wat. Thanks0
Paloma, now connected with Rheem, had some B-vent models. Low Energy in Colorado is an expert on tankless. tanklesswaterheater.com I think.Bob "hot rod" Rohr

Rinnai has the RH180 which was a 90k B-vent tankless mounted on a 40 gal water heater. It needed 4" b-vent which on a retrofit can be a problem.0
I wouldn't. B-vent isn't meant for positive pressure. It's meant for a negative pressure like through the roof with a good draft.0
Not all on demand water heaters are positive vent, so you would use the B-vent for them. I know the Aquastar and the Paloma used B-vent, and Jack definitely knows about the Rinnai line, so B-vent can be used as directed.
