Where can you install a water heater?

• Basement: Basements are the most common place to install water heaters due to their cooler temperatures and proximity to plumbing lines.
• Utility room: Utility or laundry rooms are great places for water heaters because they typically have good access to plumbing, gas, and electrical connections.
• Garage: Garages offer plenty of space and easy access for maintenance and repairs. Make sure the water heater is raised off the ground by at least 18 inches to prevent damage and keep flammable items away from the water heater.
• Crawl space: Crawl spaces are out of the way and close to plumbing lines. The area should have adequate clearance for installation and maintenance and good ventilation.

Where you can’t install

• Living areas: Water heaters should not be installed in living areas due to safety concerns, noise, and the potential for water leaks. Installing a water heater in a bedroom or living room also increases the risk of carbon monoxide exposure for gas water heaters.
• Bathrooms: Bathrooms are not a suitable location for water heaters, especially gas models, due to the risk of leaks, steam, and moisture. The confined space may also limit proper ventilation.
• Outdoors: Placing a water heater outdoors, especially in areas prone to freezing temperatures, can cause the pipes to freeze, leading to water and internal part damage.

Installation tips

• If installed in a garage, the heater should be raised at least 18 inches off the ground to prevent potential fire hazards.
• In areas with closed water systems, an expansion tank may be required to manage pressure changes when the water heats up.
• Gas water heaters must be vented to prevent dangerous gas buildup. Check that the vent pipes are clear and properly aligned for efficient exhaust.
• In case of leaks, a drain pan beneath the heater can help catch water and prevent damage to surrounding areas, especially in basements or closets.

FAQs

Who is best to install a water heater?
A licensed plumber is the best person to install a water heater, as they are experienced with the necessary plumbing, gas, and electrical connections. Some electricians may also handle the job, especially for electric water heaters.

Why is installing a water heater so expensive?
Water heater installation can be expensive due to the cost of labor, materials, and any necessary adjustments to plumbing or electrical systems. Permits and codes may also drive up the cost, especially for gas water heaters.

Is a tankless water heater better?
Tankless water heaters can be more energy-efficient because they heat water on demand, rather than storing it in a tank. They take up less space, but may have higher upfront costs and might not meet high hot water demands in large households.

Does home insurance cover a water heater?
Home insurance typically covers water heaters if they are damaged by a covered event, such as a fire or flood. However, general wear and tear or age-related failures are usually not covered.

How long do hot water heaters last?
Traditional tank water heaters typically last 8 to 12 years, while tankless water heaters can last up to 20 years with proper maintenance.

How often should I flush my water heater?
You should flush your water heater once a year to remove sediment buildup and improve efficiency. In areas with hard water, more frequent flushing may be needed.

Is installing a hot water heater difficult?
Installing a water heater can be challenging, especially if it involves modifying plumbing or gas lines. It’s recommended to hire a professional to ensure the job is done safely and correctly.
