Water From a Gas Heater Is Not Hot Enough

When a gas water heater doesn’t provide enough hot water, perform the following diagnostics:

1) Check the pilot light to be sure it hasn’t gone out. If it has, follow the manufacturer’s instructions on how to relight it.

2) Turn the thermostat dial to a hotter setting. If the flame ignites when you do this, leave the dial at that setting and check your water temperature in about one hour. To do this, put a meat thermometer into a cup and let hot water from a faucet flow in for about a minute. Then read the temperature.
