My Bradford White water heater has been tripping every morning so I'm
on my way to replacing both upper and lower thermostats. The upper
thermostat is an Apcom WH10-A double-throw with a hi-limit reset, and I
will replace it with the exact same model.
The lower thermostat is an Apcom WH-9 which is a single-throw without a
hi-limit reset. However, Apcom also has a similar model WH9-6 which
appears to be the same or compatible replacement thermostat but with a
hi-limit reset button.
The question is: would the lower thermostat with the red reset button
be a better choice than the one without the button, given the fact that
the upper thermostat already has an existing red reset button? Cost is
not an issue since we're talking just 5 bucks price difference. What's
the point in having 2 hi-limit reset buttons, one for each thermostat?
Is this a good idea?
Any advice would be appreciated. Thanks.
P.S. It was 26 degrees F in DC this morning - bitterly cold, in my
experience, and this could be causing my water heater to go bad.
