hi. i have a commercial establishment that requires additional BTU's.
my plumber has the following design:
- use 2 water heaters; 40 gallon & 65 gallon
- each water heater to service 2 different "zones"
- main water line comes in and 'T's' off to each water heater
- hot and cold water supply lines from 40 gallon water heater goes to zone 1
- hot and cold water supply lines from 65 gallon water heater goes to zone 2
please review diagram attached and let me know if this is a feasible solution.
