Water heater too hot?
If so, there are a few things that you need to check out immediately.
The first, easiest and most cost efficient solution to this problem is to check your hot water heater’s thermostat.
Some people will overlook this simple step simply because they think that they haven’t touched the water heater thermostat since they moved in to their house. However, many water heaters are in multiple use rooms and it is easy to accidentally nudge the thermostat and never realize anything has happened. Another scenario could be kids playing near the water heater. Either way, if you can turn down the thermostat to solve the problem, it is an easy fix.
Electric water heaters will generally have two heating elements: one on the bottom of the tank and one on the top. Each one should have its own thermostat which should be attached to the side of the tank for the most accurate reading. Check and adjust each thermostat to the desired temperature. If the thermostat is no longer touching the side of the tank, the thermostat will need to be reattached or replaced. A professional plumber can take care of this quickly and easily.
Other problems are more severe (if not altogether dangerous) and should result in a call to a licensed plumber. If there is steam coming out of your pipes instead of water there is a very good chance that your pressure release valve is not functioning properly. Turn off the power or gas supply to the hot water heater and call a professional to replace the pressure release valve.
In this scenario, there is a chance that your hot water heater could explode if you do not fix the problem immediately.
