You should not set the thermostat to more than 120 degreesFahrenheit. If you are unable to get more hot water, maybe you want to buy a new one.

In the case of electrical heaters, the following procedure shall be followed:

  • Check the thermostat level. Set it to a higher temperature but it should not increase 120 degrees Fahrenheit.  If you still get only warm water, you may want to check the element of the thermostat.
  • For this, use an electrical tester. Place it near the thermostat element. The current won’t go through the bad element. You can buy one and replace it by reading the guidelines mentioned in the manual or follow the given steps.

  • To begin with, turn off the water heating unit.
  • Whenever replacing a heating unit, turn off the water to avoid electrical shocks and also to take out pressure from the tank. For this, open the hot water tap and let the water be entirely out in a tub or bucket.
  • Open the part. Use a wrench to do so.
  • Use a screwdriver and disconnect wires joined to the bad element. 
  • Loosen the bad element first with a wrench and then with your hand. Put it away and take the new one and first tighten it with your hand. After this, tighten its wrench. Make sure you don’t tighten it more than expected.

  • There is a chance that the tap or valve is loosely tightened, hence place a bucket or tub below the leakage and look for the cause.
  • You may want to buy the right valve for your water heater.
  • Switch off the power and water supply to the water heater.
  • Run hot water on the valve for a few minutes.
  • Open the relief valve so that the pressure from the tank is released.
  • Lose the old valve with the help of a wrench by turning it in an anticlockwise direction.
  • Put the pipe tape in the clockwise direction around the new valve and install it. Use the wrench to tighten the new valve.
  • Switch on the power and water supply again. If there is still a water leak, you may want to buy a new heater.
