Introduction
Are you feeling the chills in the shower or sink while using warm water? This could be a sign that your water heater is not working correctly. Water heaters are essential in providing hot water for various domestic purposes, including bathing, cleaning, and cooking. They are also necessary for certain commercial applications, such as restaurants and hotels. This article offers expert guidance on restarting a water heater that has stopped working.
Before we dive into the technical details, let’s first understand what a water heater is and how it works. A water heater is a device that uses an energy source to heat water above its initial temperature. The heated water is stored in a tank or container until it is needed. When someone opens a hot water tap, the hot water flows out of the container and into the pipes leading to the tap.
Water heaters are powered by different sources of energy, including electric, gas, and solar. The most common type of water heater in households is the electric heater, which uses an electric coil to heat the water. On the other hand, gas water heaters use a gas burner to heat the water. Regardless of the type of water heater you have, it is essential to understand how to restart a water heater if it stops working.
In the following sections, we will provide a step-by-step guide on how to restart a water heater. We will also discuss the advantages and disadvantages of restarting a water heater instead of replacing it. Finally, we will explore commonly asked questions about water heater restarts.
How to Restart a Water Heater
The following are the step-by-step instructions to restart a water heater:
Step 1: Turn off the power supply
The first step when restarting a water heater is to turn off the power supply. For electric water heaters, this means turning off the circuit breaker that controls the water heater. For gas water heaters, turn off the gas valve that supplies gas to the water heater. This step ensures that there are no electrical or gas hazards when restarting the water heater.
Step 2: Turn off the water supply
The next step is to turn off the water supply to the water heater. This involves closing the valve on the cold water line that enters the water heater. By turning off the water supply, you prevent the heater from refilling with water while you are working on it.
Step 3: Drain the tank
The third step is to drain the tank. This is done by attaching a garden hose to the drain valve at the bottom of the tank and allowing the water to drain out. Drain the tank until the water runs clear, indicating that there is no sediment or debris in the tank.
Step 4: Refill the tank
The fourth step is to refill the tank. Turn on the cold water supply and let it flow until the tank is full. Check the hot water tap to ensure that there is no air in the tank. If there is air in the tank, let the hot water run until the air is expelled and the water flows smoothly.
Step 5: Turn on the power supply
The fifth step is to turn on the power supply. For electric water heaters, turn on the circuit breaker that controls the water heater. For gas water heaters, turn on the gas valve that supplies gas to the water heater. This will provide the energy source needed to heat the water.
Step 6: Test the water heater
The last step is to test the water heater by opening the hot water tap and letting it run for a few minutes. If the water is hot, the water heater has been successfully restarted. If the water is not hot, turn off the power supply and call a professional to inspect the water heater.
Advantages and Disadvantages of Restarting a Water Heater
Restarting a water heater has both advantages and disadvantages. The following are some of the pros and cons:
Advantages
Cost-effective
Restarting a water heater is generally more cost-effective than replacing it. If the problem with the water heater is minor, such as a tripped circuit breaker or a blown fuse, restarting the water heater is a quick and easy fix that won’t cost you a lot of money.
Saves time
Restarting a water heater typically takes less time than replacing it. You can restart a water heater in less than an hour, depending on the extent of the problem. On the other hand, replacing a water heater can take several hours or even days, depending on the type of water heater and the installation process.
Environmentally friendly
Restarting a water heater is more environmentally friendly than replacing it. Water heaters are made of metal and other materials that take a long time to decompose. By restarting a water heater, you extend its lifespan and reduce the amount of waste that goes into landfills.
Disadvantages
Risk of further damage
Restarting a water heater can be risky if you don’t know what you’re doing. If you don’t follow the correct procedure, you could cause further damage to the water heater, leading to costly repairs or replacement.
Not always effective
Restarting a water heater is not always effective, especially if the problem is severe. If the water heater is old or damaged beyond repair, restarting it might only provide a temporary fix. In such cases, it’s best to replace the water heater.
Safety hazards
Restarting a water heater can be dangerous if you don’t take the necessary safety precautions. For example, if you don’t turn off the power supply or the water supply, you could expose yourself to electrical or gas hazards.
