i buy my irrigation supplies from a local plumbing house and they gave me the "wholesale" price, but i saw the same unit on ebay for about the same price as i paid. i was concerned about the maintenance of the tankless. my elec tank heater is a 60 gallon and i have done nothing in 11 years to it.i have been told i need to run a solvent through the tankless once a year and if it were to go bad, i can see where it would be cheaper to replace the unit rather than repair.
a lot of my irrigation accounts have these heaters and love them, the longest one i know of is about 8 years old and no problems yet. as stated, i'm primarily doing it to get the heater out of the bathroom, to make room for a closet....
