What type of thermostat (there are several, the commonest is a rod)?
The simplest thing is that there isn't any hot water! You can check at the hot water heater as well as at the faucets. Check the heater itself and make sure it isn't leaking. If it is a gas heater, make sure the pilot light is on! If it is an electric water heater, make sure the breaker isn't blown and reset if necessary. If all else fails, time to call a plumber, unless you like the challenge of replacing it yourself, which isn't as daunting a task as you may think!
When you want to know when your hot water heater is broken, simply run your faucet and test the water. If it's cold, the heater is broken.
Yes. I would. If you are replacing the hot water lines, it is also a good time to drain the hot water heater and get rid of all the junk at the bottom of the hot water heater. That should be done once a year. Your hot water heater must be off when you do that, your hot water heater should be off when you drain your hot water heater. You will see boiler scale come out of your water heater. Leaving the boiler scale in your water heater makes it less efficient. It makes it harder to heat your water. It is the same as throwing money down the drain. If you want to give your money away, you should give it to the Salvation Army instead of the Utility Company.
It is called this as it heats up or brings up the temperature of cold water to hot. In other words, it is producing hot water by heating it. Some people incorrectly believe it is redundant to refer to "hot water" and "heater", but there are many other types of heaters, so the distinction of one creating hot water is entirely proper.
For a water heater, 120 °F (49 °C) is the factory setting, and is the low end of the heating scale. Most are set higher, at 130°F to 150°F to allow for the cooling of the water in the pipes. The hottest setting is about 160°F, which may be too hot for human use (showers) but suitable for washers and dishwashers.In water heaters with two, an upper and a lower thermostat (which perform different functions), the upper thermostat should be left at 120°F.
To test a hot water heater thermostat, you can use a multimeter to check for continuity in the thermostat. First, turn off the power to the water heater. Then, remove the access panel to expose the thermostat. Use the multimeter to test the thermostat's terminals for continuity. If there is no continuity, the thermostat may be faulty and needs to be replaced.
First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.
Someone turned up the thermostat, or the thermostat has failed. The thermostat tells the heater what temp to keep the water at.

In a hot water heater, a thermostat regulates the heat
The thermostat needs to be adjusted. Get the super to do it.
To replace the thermostat on your hot water heater, first turn off the power and water supply to the heater. Remove the access panel and insulation to access the thermostat. Disconnect the wires from the old thermostat and remove it. Install the new thermostat and reconnect the wires. Replace the insulation and access panel, then turn the power and water supply back on.

Check into the temperature control valve--this is different than the thermostat.
Your hot water heater may keep going out due to issues like a faulty thermostat, sediment buildup, or a pilot light problem. To prevent this in the future, you can regularly flush your water heater to remove sediment, check and replace the thermostat if needed, and ensure the pilot light is functioning properly. Regular maintenance and inspection can help prevent future issues with your hot water heater.
To troubleshoot a water heater tap not producing hot water, check the thermostat settings, ensure the power source is connected, inspect for leaks or blockages in the pipes, and consider calling a professional if issues persist.
Either the thermostat has been set too low, your hot water heater is not big enough, or your hot water heater has not been installed properly.
