Expensive to retrofit in place of a tank water heater due to gas demands/flue requirements.
Had a customer last year trying to get me to sign off on a set of tankless units that were "supposedly" struck by lightning. The installer didn't use dielectric unions and the current travelled through the units destroying the electronics.
I get curious george customers all the time trying to whittle my set price ($1000 on up) to begin to make the switch.
When the efficiency of these units come into play on these, they do good but many considerations are the norm.
I called the customer who needed his endless hot water box on the wall on new years day. The one who was proud as hell to have one because he's better than me because he can take a shower for days.
No one around to fix it, he ended up getting parts for it a week later and had it up in running, 8 days without hot water.
The maker of the product sympathized with him since no one around to fix it, gave him major components, basically a whole other unit to fix his problem. Sad.
I bet the wifey and kids love tankless........until the next time it breaks. He said a tank heater is going back in if it breaks again.
I'm actually trying to get one of these tankless mfg's to give me one as a demo. I want to be able to cut one of those compartments apart after a year/two years and get true digital pics of the inside of them to see the buildup that the required cleanings don't address/clean. And I will follow the mfg specs to a tee. No one wanna give me a tankless though.
