Hi J: What temperature do you need. I have lot's of info on 35,000btu through 95,500btu fully modulating electric units. Please E-mail me at firstname.lastname@example.org & I'll send it to you. Or call me at 1 800 851 9891. Regards, Brian Wood. These units are actually residential tankless water heaters, but I use them for every water-heating application. B.
