I am trying to find a replacement for a Robert Shaw R110RTSP that has failed. Lowes carries the updated version of that thermostat but it has a main burner pressure of 5". My old failed unit is 3.5". The exact replacement is via the net and over $200. The one at Lowes is $60
My question is can I use this new t-stat safely on my water heater? ...or am I totaly out of the ballpark? anyone, anyone.....Bueller?
stinking and greasy in MI
