The furnace room had two furnaces and a large hot water tank. The one furnace was ready for replacement and the hot water tank was a close second. We removed the two furnaces and installed one in the back corner (we call him frankenstein!). The hot water heater is now a demand unit installed on the wall. (right hand wall)
This is the new hot water tank and we love it.
Here is a copy of the schematic for the closed loop system.
