Now I am looking at getting a Bosch Aquastar AQ125XNG. I can't find any info on it. Boschs website has the 125 Aquastar series but just BO and FX...
AquaStar 125B, 125HX, 125FX, 125BS Tankless Water Heater Models by Bosch
Does anyone know anything about this model? I would need to do a side vent for it and use my existing galvanized one just for my furnace. The problem is I built a deck that pretty much blocking where I would vent. I may be able to go past it but IIRC they say to go only 15' w/ a max of 2 90s; may not be an issue. I can't vent under my deck, can I (my deck is only 2' off the ground).
Do you need a power vent kit to do horizontal or is that just to increase length?
596 said that most tankless water heaters require a larger gas supply line than tanked ones, any idea what it is? I believe mine right now is 3/4" reduced to half.
