Indirect water heater job from last year

[maniak]

Haven't posted on this wall for a while, here goes!! This system is in a care facility for seniors. The problem was they were not able to keep up with the hot water demands and were replacing storage tanks every year. There are 2 large hydrotherm modular boilers that heat this building, 7 burners for each boiler. 3 burners on one of the boilers are designated for heating the domestic water. I did this job in July of last year. Enjoy.

existing system, these tanks were installed in approx. 1999. 4 100 gallon storage tanks

existing system used parallel piping

the domestic water was heated through this heat exchanger. The 3 boiler burners would heat the water to the heat exchanger with gravity convection.

New system, 3 smart 120 indirect water heaters. This is the first project that we used smart water heaters from triangle tube and I have no complaints.

We isolated each indirect as its own zone with it's own boiler burner so if anything happens with one, we can isolate and bypass it.

Thanks. Whoever originally built this mech. room took a lot of pride in their work. I like to think whatever I touch in there I keep it looking just as good.
