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.
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.
Check the thermostat or heater core

The thermostat needs to be adjusted. Get the super to do it.
Check into the temperature control valve--this is different than the thermostat.

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.
either your hot water heater has been installed incorrectly or the thermostat has been set too low Sorry to butt in BUT there is NO THERMOSTAT on a hot water heater there is a AQUASTAT and sometimes the heater short cycles just to maintain the SET temperature
Single pole.
What temp. thermostat did you put in? Try a higher temp. one. or check to see if heater core is clogged
Check your thermostat. Probably stuck open.
