Girard Generation III water heater.
I upgraded our Girard water heater to the Gen III unit a few months back. Up in the Canadian Rockies right now near Banff and we have been on the road for a month. Went through 100+ desert temps. with very warm incoming water, and currently in 40 degree nights and very cold water.
The verdict so far is great. Very happy I made the change. The new unit maintains what ever temperature we set it and the output temp is constant and steady. I really like having an LCD screen to see exactly what is going on with the heater, no guessing.
