For expert installation, Cornerstone Plumbing & Mechanical is here to help.

When it comes to comfort in your home, few things are more important than having a reliable hot water supply. Whether it's for your morning shower, washing dishes, or doing laundry, a functioning water heater is essential. If you're considering installing a new water heater or replacing an old one, the process can seem a bit overwhelming. However, with the right knowledge and a little preparation, you can ensure that the job is done right and your new water heater runs smoothly for years to come. Let's dive into the steps involved in installing a water heater.

 

 

1. Choosing the Right Water Heater 

Before you begin installation, it's essential to choose the right type of water heater for your home. There are several options available, each with its benefits:

  • Tank Water Heaters: These are the traditional water heaters that store a large amount of hot water in a tank. They’re reliable, easy to maintain, and come in various sizes to meet your needs.

  • Tankless Water Heaters: These heaters provide hot water on demand, eliminating the need for a storage tank. While they can be more energy-efficient, they might require a higher upfront cost.

  • Heat Pump Water Heaters: These systems use electricity to move heat from the air or ground to heat the water, offering energy efficiency.

The size of the water heater should be determined by the number of people in your household and your water usage. For instance, larger families may need a bigger tank or a tankless system to meet high demands. 

2. Gather Necessary Tools and Materials 

Before you start the installation process, ensure you have all the required tools and materials. Here's a list of what you'll need:

  • Wrenches

  • Pipe cutter

  • Teflon tape

  • Adjustable pliers

  • Safety gloves

  • A new water heater (of course!)

  • Copper pipes or flexible connectors (if necessary)

  • A temperature and pressure relief valve (if your new heater doesn't come with one)

Having everything ready will help streamline the installation process, reducing the chances of interruptions along the way. ⚡

3. Turn Off Power and Water Supply ⚠️

Safety comes first! Before you begin, make sure to turn off the power to the old water heater (if it's electric) or shut off the gas supply (if it's a gas-powered water heater). Additionally, you'll need to turn off the main water supply to the heater to avoid any leaks or flooding. 

4. Drain and Disconnect the Old Water Heater 

Now it's time to say goodbye to the old heater! Begin by draining the remaining hot water in the tank. You can do this by connecting a hose to the drain valve and allowing the water to flow out into a suitable drainage area. This may take a little time, depending on the size of your tank.

Once the tank is empty, disconnect the cold and hot water lines, and then remove any gas or electrical connections. Be sure to take extra care when dealing with electrical wiring or gas lines – if you’re unsure, it’s always best to consult with a professional. 

5. Prepare the New Water Heater 

With the old unit out of the way, it's time to set up the new water heater. Begin by positioning it in the desired location, making sure that it's level. This step is important to avoid any pressure issues and ensure proper water flow. 

For gas models, you’ll need to connect the gas supply line and ensure that the burner is functioning properly. For electric models, make sure the electrical connections are secure, and check that the thermostat is properly set. If you're not comfortable handling these connections, it's always a good idea to reach out to a professional plumber or electrician to ensure everything is done safely. 

6. Connect the Water Lines 

Once the heater is in place and the power supply is connected, it’s time to hook up the cold and hot water lines. Use flexible connectors or copper pipes, depending on your system's requirements. Be sure to apply Teflon tape to the threaded connections to avoid any leaks. Tighten the fittings securely but don’t over-tighten, as this can cause damage to the threads. 

If you're installing a tankless model, be sure to follow the manufacturer’s guidelines for the water connections to ensure everything is set up correctly. Tankless systems may require additional modifications to your plumbing system, so don't hesitate to consult a professional if necessary. 

7. Install the Temperature and Pressure Relief Valve 

The temperature and pressure relief valve is an essential safety feature that helps prevent your water heater from overheating or over-pressurizing. Most water heaters come with this valve pre-installed, but if not, it’s important to install it yourself. This valve should be connected to a discharge pipe that directs any excess water pressure safely outside your home. 

8. Fill the Tank and Check for Leaks 

With everything connected, you’re almost done! Now, you’ll need to slowly turn on the water supply and allow the tank to fill. This process can take several minutes, depending on the size of the heater. Once the tank is full, check all of the connections for any signs of leaks. If you find any, tighten the fittings and inspect again.

9. Restore Power and Test the System 

Once you’re satisfied that everything is securely connected and free of leaks, turn on the power to the water heater. For gas models, light the pilot light according to the manufacturer's instructions. For electric models, turn on the circuit breaker.

Finally, test the system by turning on the hot water faucet and letting it run for a few minutes. Make sure the water is heating properly and that there are no unusual sounds or smells. If everything looks good, congratulations! You’ve successfully installed your new water heater. 

10. Regular Maintenance 

To ensure your water heater continues to work efficiently, it's important to perform regular maintenance. This includes flushing the tank yearly to remove sediment buildup, checking the anode rod, and inspecting the temperature and pressure relief valve. Regular maintenance can help extend the life of your water heater and save you money in the long run.
