Heating Element, Thermostat & ECO

Early model water heaters with 110 VAC heating
capacity used a bolt-on heating element and a one
piece thermostat/E.C.O..
This 110 VAC system has an adjustable rectangular
thermostat that is surface mounted to the inner tank
and retained by a steel clip. The temperature settings
are HI, MEDIUM, and LOW. If the thermostat is
making unobstructed contact with the aluminum tank
and it is set to the HI position, it should heat the water
to 130° F. It will take longer to heat a tank of water on
electric than gas.
The heating element was changed in 1996 from
1500W to 1400W bringing the amperage draw down
to 12.7 amps and allowing more cushion for the
15 amp circuit breaker that is normally placed in line.
This change adds a few minutes to the heating time.
There are 110 VAC aftermarket conversion kits being
offered by distributors in which the heating element is
screwed into the tank where the drain plug is located.
We do not offer such a kit. Our kit includes the tank
with the 110 VAC components already installed in it.
