They don't work on anything older than 10 years. No bueno. Why if car repair people were the same way, "Oh, sorry, your car is older than 10 years, buy a new one". Yeah, no.

I just called and they dont work with Tankless water heaters in Phoenix Arizona! What a joke! Change your name!!

Water heater failed and flooded the garage late in the evening. Water Heaters Only had someone on sight first thing in the AM to replace the unit as well as install a new water softener system. Price
