How Do I Turn the Hot Water on in My House?
Assuming you would like tips for turning on the hot water in your home:
If you have a gas water heater, locate the thermostat and turn it to the “High” position. Then, find the knob near the bottom of the tank and turn it to the right until you hear gas flowing into the unit.
Once you hear gas flowing, ignite the pilot light. If you can’t find your pilot light, consult your owner’s manual. Finally, turn the knob back to the “Pilot” position.
If you have an electric water heater, locate the thermostats on top of unit and set both to desired temperature. Make sure that each thermostat is set at least 5 degrees above room temperature so that there is no risk for scalding.
Why Isn’T My Boiler Giving Me Hot Water?
There are a few reasons your boiler might not be giving you hot water. First, check to see if the pilot light is lit. If it’s not, then that’s probably why there’s no hot water.
Second, check the thermostat to see if it’s set to “hot.” If it’s not, then adjust it accordingly. Finally, check the pressure gauge to see if the needle is in the green zone; if it’s not, then you’ll need to bleed the radiator.

If your boiler doesn’t have a thermostat, you can usually find a dial or switch labeled “hot” or “heat” that you can use to adjust the temperature.
