Many manufacturers set the thermostat to 140 degrees Fahrenheit by default. Something is preventing gas from reaching the pilot light and the burner. It is possible that the gas supply was inadvertently cut off. Just make sure that the gas is turned on and that the gas valve is not in the closed position.
If this is the case, open the valve and follow the steps to turn the pilot light back on. If it trips, the dedicated water heater circuit breaker may not seem “off”, but it might be a little out of place and not quite in line with the other circuit breakers. Water heaters require a lot of energy and keeping one on its own dedicated circuit is the best option. If the weather in your area has been below zero and the boiler is still working, try setting the water heater to maximum temperature until it starts up again.
Water heaters of newer models do not always have a pilot light, however, if yours has one, check if the flame is out. A tripped high-temperature cut-off switch is one of the main reasons why hot water no longer enters your home. Concern for safety, coupled with the technical nature of repairing a water heater, means that it is better to leave work to professionals. Learning and managing the situation is sometimes the best thing, although you can buy a larger water heater if needed.
First try resetting the water heater, and if that does nothing, you will probably need to replace the component. However, if you need to replace the heating elements, be sure to turn off the water heater completely. Sometimes, the only thing that can make getting out from under those warm and warm blankets are the visions of jumping in that steaming hot shower. Point-of-use tank water heaters come in sizes from 2.5 gallons to 20 gallons, depending on the level of hot water demand.
With the traditional tank water heater, turning the faucet knob starts the hot water process that makes its journey through the pipes. These water heaters have fewer moving parts that can wear out over time, and their parts are only used when they are needed to supply hot water on demand, not consistently as with storage tank water heaters. If you have an electric water heater, the first thing to check if you have problems with hot water is the circuit breaker. To have hot water as quickly as possible, avoid using hot water when the recovery process is not finished.
