Electric Hot Water Lower Thermostat Bypass


40 Gallon electric water heater has two 3500 watt elements and two thermostats. Lower thermostat has failed. Any reasons I could or should not disconnect wiring from upper to lower and just run with the upper temporarily?
Heater is only used to supply washing machine; maybe three loads per week.
Upper thermostat is set to 100.
Thanks.

Re: Electric Hot Water Lower Thermostat Bypass


The first thing I wanna say is electric water heaters are really cheap......... But yeah.

This water heater only supplies your washing machine? In that case it sounds fine.

The lower part of the tank will probably be cold. So figure your hot water capacity is about 1/3 of what your tank indicates. A 50 gallon WH is probably worth about 15 gallons of hot water with the lower out.

These are all just guesses, I don't know for sure.

I'm also very curious about the plumbing circumstances that lead to a water heating supplying just a washing machine.

Show us some pictures, we loooove pictures of pipes on these forums :D

Re: Electric Hot Water Lower Thermostat Bypass


Indeed there is a story behind it. Originally house was a center aisle horse barn, with stalls on one side and a groom's apartment on the other.
The old b*****d who built the barn walled off the bathroom from the apartment.
Whenever the groom needed to use the bathroom, she was forced to exit the apartment and walk the length of the aisle, presumably observing the horses along the way.
So the owner assured himself that his horses would be checked on quite regularly! But kind of cruel to the groom on a cold, dark night.
We converted the barn; made the groom's bathroom into a laundry room and left the hot water heater in place.

That's fantastic haha.

As long as you're not trying to wash in super hot water, I think you're fine! But I think you should replace the faulty thermostat anyway. Or if you can't be bothered, replace the whole heater. Though if the tank seems fine, the thermostats and elements are all very very cheap.

A lower thermostat costs about $10, why not replace it?

More likely to be the lower heating element than thermostat. Same story as thermostat, cost about 10 or $15 to replace.

Re: Electric Hot Water Lower Thermostat Bypass


Nice thing about electric water heaters is you can replace pretty much every component for about $50 as long as your tank is decent. Can't say that for gas heaters.
