Your heater is one of the most important pieces of equipment in your home, and you want to make sure it’s working properly. Here’s a step-by-step guide on how to turn on your water heater. Happy heating! 

Although it’s not something we often think about, the water heater is one of the most important appliances in our homes. It plays a crucial role in keeping us warm and comfortable, and ensuring that we have hot water when we need it. So what do you do if your water heater isn’t working? Don’t worry – this step-by-step guide will show you how to turn on your water heater, so you can get back to enjoying those long, hot showers in your home.

First of all, there are three types of water heaters: gas, electric and tankless. We will cover all these three types in this guide, but if you have a different type please comment below and we will add it to the guide.

How to turn on Gas Heaters?

First of all, what is a gas heater? Gas Heaters are one of the most common types of water heaters. They are often used in regions where electricity is not very reliable, or when high power bills are an issue. Gas heaters operate by burning gas (usually natural gas) to create heat which heats up the internal heating element (coils). The heated coils then transfer the heat to the water in your heater.

In order to turn on the gas heater, you will need to first locate your breaker box and check that the heater’s power is turned off. Once this has been done, follow these quick steps:

1. Locate the gas shut-off valve which is usually nearby the tankless/water heating unit where the gas line is connected.

2. Check that there isn’t any gas leaking by using a match or lighter and checking for any sparks which would indicate gas leakage. Be sure to turn off the heater before you attempt this step just in case something goes wrong!

3. Now apply the wrench to the valve and simply turn it until you feel a click. Once you hear this click, turn it back (about 90 degrees) and then remove the wrench. The valve should now be turned off. Put the wrench somewhere safe where no one can access it which might accidentally turn on your gas water heater!

4. Now open up the box that contains the reset button of your heater and press it (reset). After you have done this, wait 5 minutes and check the heater by pressing the reset button again. If your water heater still doesn’t turn on, or lights up there might be a more serious problem with the gas line which you should call a professional for.

5. Now get your wrench and turn the valve on to the right which should turn off the gas to your water heater. Now you are ready to connect the heater back up! Simply follow these steps in the reverse order and please be extra careful when turning on your gas water heater, as it is very dangerous if you do anything wrong.

How to turn on an Electric Water Heater?

Electric water heaters are quite a bit simpler. They use a heating element that heats the water using electricity. This heating element is powered by an internal heater box which heats up to produce hot water when you need it.

The major advantage of an electric water heater is the efficiency of the heater. Electric heaters are usually 70% more efficient than their gas counterparts, which leads to lower electric bills and less strain on our environment.

An electric water heater is usually connected to your home via a standard wall outlet. You can simply plug it in and turn it on! However, you should check that the power is off either at a breaker box or a fuse box first.

If you have an electric water heater, follow these steps:

1. Turn off the power at a circuit breaker/fuse box.

2. Now locate your water heating unit and make sure it’s turned off. If you do not feel comfortable with this step, please call a professional for assistance.

3. Now how to turn on your heater is simple – simply plug in your electric water heater (ensuring the power is shut off of course).

4. Wait for 10 seconds and then turn on the breaker/fuse box to power up your water heating unit.

5. Now go to the unit and check that your heater is working by pressing the reset button. If this doesn’t fix it, there might be a problem with your heating element which you should call an electrician about!

How to turn on tankless water heaters?

Tankless water heaters are a bit different from traditional water heaters. Instead of storing gallons and gallons of hot water, tankless water heaters produce hot water on demand by heating up cold water as it flows through the unit. These units have been growing in popularity over the years because they use significantly less energy, especially if you have a smaller home.

Tankless water heaters are a great way to conserve energy but can be a pain to turn on if you don’t know what you’re doing. The biggest reason for this is that there are no settings or dials like traditional water heaters. With tankless water heaters, you need to push buttons that control the temperature of the unit. If your unit does not have any buttons, you will need to call a professional for assistance.

Turning on a tankless water heater is quite easy, you just need to follow these simple steps:

1. First, you need to locate your tankless heater and make sure the power is completely shut off at a circuit breaker/fuse box.

2. Next, press any buttons on your unit if there are any that control settings for the heater (temperature control). If there are no buttons or they do not fix it, then you will need to call a professional.

3. Now how to turn on the unit is simple – simply press the reset button! This should turn it on, however, if not there might be a problem with your gas line which you should call a professional about!


Water heaters are a necessary part of modern life, and keeping them running properly will save you both money and time. It can be a little bit intimidating for people who are not as familiar with this type of appliance, but as long as you follow the instructions step-by-step, you should have no problem fixing any problems at all! Good luck!
