The Complete Guide to Water Heater Installation in Roanoke, VA: What You Need to Know

1. Types of Water Heaters

There are various types of water heaters available in the market, each with its own pros and cons. Understanding the different options will help you make an informed decision. The following are the most common types of water heaters:

Conventional Storage Tank Water Heaters

Conventional storage tank water heaters are the most common type found in many homes. These heaters store and continuously heat a large amount of water in a tank, ready to be used when needed. They are cost-effective but may have higher energy consumption.

Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, heat water only when you need it. They provide hot water on demand, eliminating the need for a storage tank. Although they may have a higher upfront cost, they are energy-efficient and provide endless hot water supply.

Heat Pump Water Heaters

Heat pump water heaters use electricity to transfer heat from the surrounding air or ground to heat the water. They are highly energy-efficient and can significantly reduce your energy bills. However, they require installation in an area with adequate space and ventilation.

Solar Water Heaters

Solar water heaters utilize energy from the sun to heat the water. They can be an excellent option for environmentally-conscious homeowners, as they rely on renewable energy. However, they may not be suitable for every climate, and installation costs can be higher.

2. Choosing the Right Water Heater

Selecting the right water heater for your home depends on various factors. Consider the following aspects to make an informed decision:

Fuel Type

Different water heaters use different fuel sources, such as electricity, natural gas, propane, or solar power. Consider the availability and cost of these fuel sources in your area to choose the most suitable option.

Size and Capacity

Water heater size and capacity should be based on your household’s hot water needs. Factors such as the number of occupants, daily water consumption, and peak usage times should be considered. A professional plumber can help determine the appropriate size for your needs.

Energy Efficiency

Energy-efficient water heaters can help you save on your utility bills in the long run. Look for the ENERGY STAR label, which indicates that the unit meets specific efficiency standards set by the U.S. Environmental Protection Agency.


Consider your budget when selecting a water heater. Keep in mind that while some models may have a higher upfront cost, they might provide savings over time due to their energy efficiency.

3. Water Heater Installation Process

Now that you have chosen the right water heater for your home, it’s time to get it installed. While it’s recommended to hire a professional plumber for the installation, having an understanding of the process can be helpful. Here are the general steps involved in water heater installation:

Turn Off Utilities

Before starting the installation, turn off the electricity or gas supply to the existing water heater. This step ensures safety during the installation process.

Drain the Tank

Next, drain the existing water heater tank to remove any remaining water. Attach a garden hose to the drain valve and direct the water to a suitable drainage location.

Disconnect Old Water Heater

Disconnect the plumbing and electrical connections from the old water heater. Carefully remove the old unit from its current location.

Prepare New Water Heater

Position the new water heater in the designated installation area. Make sure it complies with the manufacturer’s clearance requirements and local building codes.

Connect Plumbing and Electrical

Connect the plumbing and electrical connections to the new water heater. Ensure that all connections are tight and secure.

Fill the Tank

Open a hot water faucet in your home to allow air to escape from the system. Once the tank is filled with water, close the faucet.

Test for Leaks

After the installation is complete, turn on the water supply and check for any leaks. Also, check the functionality of the new water heater by running hot water from various faucets.

4. Maintaining Your Water Heater

Proper maintenance is essential to ensure the longevity and efficient performance of your water heater. Here are some maintenance tips to keep in mind:

Regular Flushing

Flushing your water heater annually helps remove sediment buildup, which can affect its efficiency and lifespan. Follow the manufacturer’s instructions or consult a professional plumber for the proper flushing procedure.

Check the Anode Rod

The anode rod is a sacrificial component that protects the water heater tank from corrosion. Inspect the anode rod regularly and replace it if it becomes severely corroded.

Insulate the Pipes

Insulating hot water pipes can minimize heat loss during distribution, ensuring that hot water reaches the faucets more quickly. This can result in energy savings and reduced wait times for hot water.

Test the Pressure Relief Valve

The pressure relief valve helps prevent excessive pressure buildup in the water heater tank. Test the valve annually to ensure it is functioning correctly and releasing pressure when needed.

Schedule Professional Inspections

Consider scheduling periodic inspections by a professional plumber. They can identify any potential issues early on and perform necessary maintenance or repairs.
