Typical U.S. 40 gallon electric water furnace. Nameplate says "Upper component 4500 watts, Lower element 4500 watts, total nouns 4500 watts". These are usually connected to a 30 amp 240v circuit, obviously they can't be running both elements at like peas in a pod time or the breaker would trip.
What is the logic of having an upper and lower factor?
How does it decide which one to run?
I own my theory, permit me hear yours.
Also, comments welcomed on my thought of building a controller that would monitor the water temp and operate Both heat elements at the same time (major rewiring required, I can fiddle with it) to try to keep up next to teenage daughter and long hot showers. Barely adequate room to put in a 50 gal hose down heater, wouldn't solve the problem. Thinking of taking the Tim Allen approach. Suitable safeguard will prevent runaway operation.
Answers: The lower element warm incomming water, the upper item keeps the upper nouns hot. Should you use too much upper water, the lower feature kicks surrounded by ( Yes, they run at the same time ) to hold on to your water hot for as long as possible.
I would turn the temp UP on the elements ( Don't exceed 130 F ) so she will use LESS hot dampen. ( The hotter the water, the more COLD you use to take home it comfortable )
If you are going to get another hose heater...turn with the tentative ' Tankless ' water heaters. Hot wet all the time...no event how much you use.
