It’s a chilly morning, and you are looking forward to a hot steamy bath. Then suddenly, you realized, you have forgotten to keep the gas pilot light on, or worse…you have run out of gas.
Now, the question is: “If my gas is off will I still have hot water?”.
Well, if your gas is off, you may still have hot water depending on your water heater system. For example, if you have an electric heater, you will still have hot water in the tank even if your gas is off. There are other scenarios as well, where you may still have hot water left if your gas was off.
For better understanding, we suggest you to read this post till end. In this post, we are going to discuss various cases in which if your gas is turned off, will you still have hot water or not. Moreover, we will also discuss some quick things on what you can do when you don’t have a working hot water system.
Learning these situations and knowing about your gas heater will help you prevent such issues in future.
If my gas is off, will I still have hot water?
Let’s get straight to the point if your gas is turned off, will you still have hot water or not:
Overall, it depends on what type of water heater you have. Many water heaters rely solely on gas to heat the water, while there are some water heaters that uses electricity to generate heat. Moreover, some water heaters come with a storage tank and some don’t.
To make it more clear, let’s learn about each of the hot water system and how they affect the heating effect on waters:
Electric Water Heater
Now, as the name suggests, electric water heater works with the help of electricity. The electrical cords inside the heater keeps the water hot, for some time.
So, in case, if your gas is off, you will still have hot water in the tank. How long the water will remain hot in electric water heater depends on the electric cords and as long as you have electric supply.
So, overall, if gas is off, you will be able to get hot water in electric water heater.
Tankless water heater with gas powered
Tankless water heater with gas ignition system solely rely on gas to keep things working. They heat the water whenever required. While, these systems are quire efficient because they only work when you need it, however, in case your gas is off, you will not have any hot water left in the system.
So, without gas, you will not have hot water and instead have cold water.
Electric tankless water heater
An electric tankless water heater is quite similar to the gas-powered tankless water heater. However, the only difference is the usage of electricity instead of gas to heat the water.
The water heater systems uses electric cords inside the system to heat the water, and doesn’t rely on gas at all. In such water heater systems, even if the gas is off, you will still have access to hot water.
Hybrid water heater system
Hybrid water heater system are advance and most useful heating system available in today’s world. Unlike tankless and electric water heaters, hybrid water heaters has dual feature – electricity as well gas.
So, in order to work, hybrid heaters uses any of the source, which ever is available. For example, they primarily uses gas to heat the system but can switch to electric when there is no gas.
So, to answer the question “If My Gas Is Off Will I Still Have Hot Water”, YES you will have hot water left in these hybrid water heating systems.

How does shut-off gas impact the hot water supply?
To understand how shutting off gas can impact the hot water supply, let’s take a look at how gas heaters work.
This way you will have a better understanding what happens and why that happens.
First, you should know that water heaters use different methods to heat water. It also depends on what type of heater you have, electric, gas, or hybrid. Now for the gas heaters, they operate with a thermostat and a burner system.
Let’s dive a bit deeper to understand how they work.
- These gas heaters have a thermostat that monitors the temperature of the water inside the tank. When the water temperature drops to a certain level, the thermostat sends a signal which then turns the burner on.
- The burner is fueled by the gas, the water is heated until it reaches the desired temperature. But without gas, the water heater can’t heat water.
- The heated water is then stored in the insulated tank where water stays hot for some time.
Without the gas supply, the water won’t be heated.
This means, that if the stored hot water is used or cools down, it can’t be reheated. If you have a water heater with an insulated tank then your hot water can stay hot for several hours.
As for the tankless water, the change in temperature is immediate. As soon as the gas supply shuts off, your hot water is gone. However, how long the water can stay hot depends on a few factors like the size of your tank, tank insulation, and usage.
So in short, if you have a water heater with a tank, then you will have hot water for a while but once it’s gone, you can’t reheat it until the gas supply is back on.
How long will hot water last without gas?
If you have a gas water heater with a tank then you can expect some hot water for a while. Typically, water can stay hot for about 2 to 3 hours.
But it depends on a few factors. As mentioned earlier, how long water can stay hot depends on your heater’s insulation, size, and usage.
For example, if you have a well-insulated water heater, then you can expect the water to stay hot for 6 to 12 hours. But if the tank is not insulated or the hot water is being used, it may run cold faster and might not even last two hours.
What to do if you don’t have hot water?
Okay, so you don’t have any hot water left. Now what to do? Don’t worry, I have got your back. Here’s what you have to do to help yourself out of this situation:
Check the pilot light
The first thing you should check is the pilot light. Most gas water heaters depend on pilot light to function properly. If the pilot light goes out, the water heater won’t be able to heat the water.
This is a common issue that can be fixed, you just have to relight the pilot light. Also, make sure to check if your thermopile voltage is low. If that’s the case, you will need a professional to get this fixed.
Alternative sources for hot water
In case you can’t get the pilot light to turn back on or it doesn’t stay light, that means there’s an issue with it.
It’s best to get it checked by a professional. In the meantime, you can boil water on the stove or in an electric kettle. This way you can have some hot water.
Check the gas supply
Don’t forget to check your gas supply. There’s a chance that it might have turned off or worse, there’s a gas leak if you can smell gas.
It’s important to call your gas provider to check if there are any issues or outages with the gas.
Moreover, also check if there is any plumbing issue that’s creating the problem. If yes, in such cases you must hire a plumber.
Check the thermostat
Look for the thermostat on your water heater. Most thermostats are set between 120 to 140 degrees Fahrenheit. If there’s an issue with the thermostat, you are more likely to get cold water. You can contact a professional to have them take a look at it.
Conclusion
To answer your question “If gas is off will I still have hot water?”, the answer depends on a few factors like what type of water heater you have, the size of your water tank, and how much hot water is used after the gas supply is off.
A water heater with a storage tank can offer you hot water for short periods but with a tankless water heater, you can’t as it shuts off immediately when the gas supply is off.
It can be quite frustrating when you run out of hot water, especially when it’s so freaking cold out there. But at least you know what to do in this situation.
So the next time, you are out of gas and hot water, don’t worry, remember to check for a few things like the pilot light, thermostat, and gas supply. Contact the gas provider if there’s an issue with the gas supply or an electrician if there’s an issue with the water heater. It’s always best to have a professional look into it if you are not sure of the problem and its cause.
In the meantime, you can use alternative methods like heating water on the stove or using an electrical water heater, to get hot water.
Now you don’t have to worry about unexpected cold surprises, just make sure to keep these things in the back of your mind. And when the gas is back on, you will be able to enjoy the much-needed hot shower. Stay warm!
