The pilot light on most water heaters can be found at the base of the unit just under the gas control valve. Open the access door or panel to the burner chamber and take a look inside. You should be able to see the pilot light tube. If there's a steady blue flame, your pilot light is operational.
The short answer is yes, as long as you don't mind using cold water. Shutting off the input to your water heater will not affect your home's main water supply. You can still run appliances like your washing machine or dishwasher, flush your toilet, and use your shower, sink, or garden hose.
In the average home, the water heater will run for about three hours each day. Total run time can range from one to two hours for new tankless water heaters to five or more hours for older tank style water heaters.
Generally, it's best to keep your water tank full and heated throughout the year. You can turn off your water heater when it is done safely, but only do this when you have a problem or if the tank won't be heated anytime soon. Turning off your water heater to save on energy bills is not usually recommended.
What does it mean if the water heater is not producing hot water? It is possible that the circuit breaker tripped or a fuse blew, so check those first if you are not getting hot water from your water heater. If that's not the issue, then it could be that the heating element has burned out and needs to be replaced.
The Pilot Light Is on But No Hot Water
Luckily, it's usually an easy fix: Just ensure the unit's gas valve is turned all the way on. (No need to touch the gas knob that controls the pilot light itself, since the pilot is working.) If this doesn't fix the issue, your unit may have a faulty thermocouple.
The lack of hot water is a common problem that can be resolved by looking for loose connections to the water heater and resetting any fuses in the circuit breaker box that may have tripped, causing a lack of hot water. After about an hour, your home will be supplied with warm water again if the breaker tripped.
You're accustomed to the sounds your water heater makes as it's running. If an out of the ordinary noise disrupts this, it often indicates a problem requiring repairs. The most common warning sound you may hear from the tank of a water heater is called kettling.
While it is not uncommon for a water heater to make noise, sounds such as humming, knocking, screeching, or tapping should be addressed to rule out the need for repairs or replacement parts.
Your unit's pilot light is always burning when the unit is on. If the pilot light goes out, the gas will stop flowing and your unit will shut off. When heating is required, the gas control valve releases the gas into the main burner where the pilot light ignites the gas.
The on/off is on the breaker panel. You can add a separate on/off switch if you want to. Gas water heaters have a gas shutoff near the unit. And they have an on/off/ pilot only position on the gas control..
That's important because gas is always being supplied to the pilot to keep the flame lit. But if the pilot flame goes out, then the gas would still be released. After a while, the gas could collect in your home and become a health hazard.
The average gas heater takes between thirty and forty minutes to heat a full tank of water. The exact time depends on the capacity. For comparison's sake: An electric heater takes at least an hour, usually up to 80 minutes, to warm up. The same goes for solar-powered units.
Ideally speaking, an electric water heater takes around 60 to 80 minutes to release hot water with a tank capacity of 40-gallon. If the tank capacity is 80-gallon, the recovery time can be more than two hours.
When a hot water pipe is leaking, or if you need to repair or replace a water heater, there are shut-off valves located near your water heater. A water heater has two shut-off valves. A cold water inlet valve (often identified by a blue handle) feeds cold water from the main supply into the water heater.
When the main water line is turned off, it cuts off the water supply to your entire house, including both hot and cold water. The reason why hot water stops flowing when the main water line is turned off is because the hot water system in most homes is connected to the cold water system.
Here are some common heat up times for different water heaters, assuming the appliances are new and properly sized for the home: Electric storage tank water heater: 60–80 minutes. Propane storage tank water heater: 30–40 minutes. Propane tankless water heater: 0 minutes.
A basic water heater will run three to five hours a day to keep its tank heated 24/7.
Gas water heaters are typically more expensive to install than electric ones, use more energy, and tend to last shorter periods. Electric water heaters are cheaper to install but use less energy and last longer.
A water heater making noise like water running could simply be the water entering the tank. However, If the sound continues, it could indicate a leak or a broken pipe.
