I have a State electric compact water heater model 6-120. When I run the faucet it seems to take a long time for the water to run hot. About a minute or two. When I take a shower I can run the hot water for about twenty minutes and then it goes cold.

Is this normal? I live in a three bedroom, two story townhouse. But I'm the only one living here. The shower is on the second floor. The water heater is on the first floor. But even the tap closes to the water heater takes too long to warm up. Do I have a problem? A plumber installed it for me in 2012.

Also, do I need to do anything to maintain the water heater or to improve performance. Like flush it or something?

  • FYI, there is no model 6-120. That is a family of water heaters. Your model is something like PCE 6 1OMSA. Also, have you actually timed how long it takes to get hot water? When you're waiting for something, it may seem much longer than it actually is. – Nick2253 Feb 24 '15 at 15:54

    I'm assuming it's a tank heater, but what size tank is it (40 gallon, 50 gallon, etc. )? If it's a 40 gallon, 20 minutes sounds about right. Though one of the elements could be dead or dieing. – Tester101 Feb 24 '15 at 17:46
  • What is the flow rate of your shower head? Simple example but if you have a 20 gallon tank and a 1 gallon a minute shower head then you will run out in 20 minutes. – treeNinja Feb 24 '15 at 17:52
  • 20 minutes? And I thought I took long showers! :)\ – ChiefTwoPencils Feb 24 '15 at 17:56
  • You can adjust the temperature setting of the thermostats that control the heating elements on your water heater. It is a simple screw adjustment. Sometimes people turn them down to save energy/money but it doesn't pay to flush 30 gallons of water down the drain. Turn it up for more hot water. – Jimmy Fix-it Feb 25 '15 at 6:28
