How to turn ON a gas water heater

How to turn ON a gas water heater. As you know, there are different types of water heaters. Make sure you speak to a qualified plumber or HVAC technician who can help determine which one is best for your needs.

You will probably be looking at tank, tankless and hybrid options, with tank heaters being the most traditional type – and in fact they were being used up until a few decades ago in many households.

These days, however, it’s very common to have a choice of units such as point-of-use or point-of-entry systems and hybrids on offer from your local manufacturers.

Hybrid water heaters are the most popular sort of all these water heating appliances – because customers realize how much their energy bills can be reduced by using them!

We will discuss here the steps of turning on a gas water heater.

Step 1: Close Any Open Faucets Or Valves

When inspecting a water heater, look for any exposed faucets or valves and make sure they are completely closed.

Because the lack of pressure lowers the temperature inside, a leak in your hot water heater could be causing you to lose electricity.

When you’re preparing to turn on your heaters for storage, it’s always a good idea to shut off any open taps to avoid wasting natural resources or, worse, losing control of hot water, which can lead to dangerous scenarios during your time of need.

Step 2: Turn On The Cold Water And Your Pilot Light

The next thing you should do is turn the cold-water source on. To be able to take a hot shower again, you’ll need a sufficient water supply in your tank.

For this reason, it’s crucial that the cold water source is functioning properly when you start up your heater again.

You must light your water heater pilot light to avoid having any drastic consequences from the release of gas fumes which might occur if you were to try turning it on without doing so.

Step 3: Turn On Your Gas Valve

Turn On Your Gas Valve

If your water heater has never been turned on before, it’s a good idea to be cautious at this point because defective valves have been known to cause gas leaks.

But first and foremost, you must switch on the main gas. If these instructions seem odd, don’t panic; you may need to adjust the valve setting slightly for this part.

Nevertheless, with the main valve set to ‘pilot’ and the gas transfer from the tank into the heating system complete and ready, we can go ahead and activate both of them at the same time.

It should start sparking at that point and time. If not, it’s possible that it’s simply out of gas – so double-check.


What is the best way to tell if my gas water heater is on?

Gas-powered water heaters have a lot of pressure on their flames. This increases the risk of combustible gases igniting at any time.

There’s a chance the flame won’t stay lit when it initially starts heating up the tubes in your water heater. As a result, a pilot light will be placed beneath or beside the flame to ensure that it remains lit during its lifespan.

If you see this light in your home, you have some extremely dangerous equipment on your hands; in fact, it may cost you thousands of dollars if left ignored for too long!

Is there a pilot light on a gas water heater?

The burner of a gas or propane-fueled water heater is ignited by a tiny flame. A pilot light is a little flame that remains lit at all times.

When the water heater needs to heat the water in the tank, it uses the pilot light to fire the gas burner. The gas then gradually heats a thermal switch in a safety valve connected to an expansion tank, which continues to fill with hot liquid as more hot water is used in bathing or dishwashing.


The greatest strategy to reduce power usage and costs is to choose the lowest available water heater. However, planners should keep in mind that smaller heaters may not be able to supply enough hot water if multiple people need to shower at the same time or if one person demands a really hot shower. Installing a gas water heater in these situations could be a good idea because they use less energy than electric heaters and can keep up with hot water demands more effectively.
