Lightly used tankless hot water heater by Bosch Aquastar... 4.3 gallons per minute of hot water on demand with no wasted heating of a tank full that isn't being used or needed at the moment... This was in use by my father when he moved out here and needed a new water heater after his went out.. used roughly 16 months prior to his passing and was then uninstalled prior to selling the house and has been in my garage for the last year as been sorting through everything of his that needed to sell, etc.. Anyway, was higher end model when he purchased, and current models on Amazon with similar specs retail from $525-850.. current model from Bosch/Aquastar is listed at $2199... that being said, it's solid, functional, and has plenty of life left so offering at $250 to start but feel free to make any reasonable offers.. Can deliver within 20 miles of 89144 for $25 and up to 40 miles from 89144 for $35. (Mileage based on start point of 10250 W Charleston Blvd)
