if an element is constantly expanding and contracting (if you keep switching the hot water heater off and on again) all the time it causes cracks and over time the water leaks into the element causing it to short which means you have to replace it.
no as it will burn out the element
Yes you can.
It is a water heater, not a hot water heater. There would be little point in using a hot water heater. I assume that is your point.
It's called water heater. There isn't a reason to heat hot water
In most homes water is made hot by an electric or gas water heater. The electic element or gas flame comes on and heats the water to the required temperature , usually around 135 f in most heaters. The heater then shuts off until it's activated again by a thermostat indicating that the water temperature has dropped.
There are a number of causes as to why a hot water heater would stop heating the water. It could be due to a fault in the circuit breaker or a problem with the element, limit switch or thermostat. Unless you know what you are doing, you should contact a qualified plumber or electrician to rectify the issue.
Sometimes the top heating element gasket can become faulty and cause the lower element to leak and this will cause moisture to build up and short out the lower element.
No water supply
Wouldn't recommend.
ring a plumber up
Not really.
No way to fix that - your tank is scrap.
In a gas water heater: The gas flame warms the water, exactly the same way as a gas stove burner does for a pan of water on the stove. In an electric water heater, an element - same as an electric range element, but a different shape - heats up from electrical current, and transfers that heat to the water.
gas water heater timer. save up to %30 on monthly water/heater/energy bill and its a 'green' solution.
no as it will burn out the element
Yes you can.
If the water from the faucet is tepid or cold, it might be time to check the electric hot water heater element. Electric hot water heaters are equipped with two heater elements that heat water. They do so through an electrical current the goes through the element. The lower element does the hard work and is most likely to be the first that burns out. Turn off the electricity, and disconnect the wires at the heating element terminals. Set the multimeter to read resistance. Touch the clips on each terminal of the element. If the Ohmmeter doesn't budge, the element is shot.
