Excel JSD-10D-10D Pro 6.6 GPM Natural Gas Tankless Water Heater Whole House with Flue Kit New
I recently installed a tankless gas water heater put it in would not work right I called customer service they gave me a few things to try did not work so they sent me out a replacement unit and it works great. They definitely have a great customer service
I've tried several times to call Excel for help. No response from them. The heater is not functional. I give this minus rating.
