Water heater costs

There are several types of water heaters you can install in your home, including standard and tankless water heaters, as well as gas and electric water. You can purchase a new unit yourself at a home improvement or plumbing supply store. Common water heater brands include A.O. Smith, Bosch, Kenmore, Rheem and Whirlpool.

Depending on the type of water heater you choose, the cost to replace a water heater will vary. Here’s a look at how tank, tankless, gas and electric water heater prices differ.

Tank water heater cost

It costs approximately $350-$2,000 to install a traditional tank water heater. Storage tank water heaters hold gallons of water, so hot water is available at any time. Compared to tankless water heaters, tank-style systems are easier and cheaper to install.

Tankless water heater cost

tankless water heater costs anywhere from $2,000-$5,000 to install. This cost estimate includes both electric and gas water heaters. 

Tankless systems heat the water on demand and can save you money on energy costs in the long run. The Department of Energy estimates that a gas tankless water heater can save you $108 per year in energy costs.

Electric water heater cost

Compared to gas water heaters, electric water heaters tend to have lower initial costs. But, they cost more to operate. That’s because, in some regions, natural gas is less expensive than electricity. That’s why where you live can play a big factor in the type of water heater you end up choosing.

Labor cost to install water heater

When pros give you an estimate of water heater installation costs, they typically quote a flat fee that includes the cost of the unit and the labor required to install it and take care of any plumbing and gas line needs

After you buy the heater that suits your needs, you can pay a pro for installation. The average labor cost for the project typically consists of an hourly rate of $65-$88 per hour.

However, you may pay more for a complicated job that takes longer. For example, if you're getting a water heater installed in a newly constructed home, the job could cost more because the plumbing work required involves running new pipes.

Search local water heater specialists and check prices.

Water heater installation cost factors

Unit and labor costs

Water heater installation costs are made up of two parts: the cost of the appliance and the cost of labor, the latter of which can vary depending on where you reside.

Water heater replacement cost

If you’re switching out an old unit for a new one, your water heater replacement costs will include the cost to remove the water heart, install the new system and adjust the pipes and gas lines.


How much you'll pay to replace or install a new water heater also depends on the type and size of the water heater (measured in gallons) and the rates charged by the installer or retailer. 

Tank-style systems range in size from 20 gallons to 80 gallons, with the 40-gallon size being the most common. Larger water heaters tend to cost a little more. For example, a 50-gallon tank may cost about $100 more than a 40-gallon tank. If your household size is more than two, you'll need at least a 40-gallon tank. If it's more than five, look in the range of 60 to 80 gallons.

Energy efficiency

The higher the energy efficiency, the more expensive the unit may cost. On the flip side, an energy-efficient model may help you save money on energy and operating costs.


Other factors that can affect the cost include the location of the system in your home. If it's difficult for the installer to access your old water heater in an attic or basement, or they have to haul your new heater up several flights of stairs, the pro may tack on an additional fee.

Special features

Some systems include integrations that notify you of leaks and other problems, which add to the hot water heater cost.

Water heater repair vs. water heater replacement costs

If your water heater is fixable, a water heater repair costs $135-$245, on average nationwide. But some repairs can cost as much as $1,100-$1,650. When repair costs start piling up, it’s time to consider replacing your old water heater with a new one.

A water heater’s lifespan ranges from 10-15 years. Eventually, the anode rod that prevents corrosion inside a tank-style heater will wear out, making the water rusty and metallic-tasting. This means your water heater needs to be replaced. If you replace the anode before it completely fails, you can extend the life of your water heater.
