Cost to Install a Water Heater – Estimates and Prices at Fixr

How much does it cost to install a water heater?

A water heater is an important aspect of a home that lasts 10-15 years, not only for the comfort and amenities, but also because it is a major source for energy use. There are many options available when choosing a water heater, and every aspect affects the price. On average, a whole-house tank water heater for a 1,500 square foot home for 3-4 people costs $600-$800.

Below, well consider some of the options for a water heater, the pros and cons, and how it affects the price.

Tankless (or instant or on-demand) systems are often considered to be much more energy efficient because they only heat water as it is needed. However, many homeowners and consumer groups argue that tankless systems arent as great as they are often billed to be, especially since comparing the efficiency of the two styles is near impossible. Tankless heaters also tend to be much more expensive ($600 installed for a tank system and $2,500 installed for a tankless system) and can be more difficult to service. The energy savings average $70-$80 a year, but it still takes decades to make up the difference in the initial cost. Tankless heaters arent good for bigger families or for people who like to use water for multiple purposes at the same time, like washing dishes while doing the laundry.

Tank water heaters have a larger reserve of hot water, meaning you can use it for multiple tasks at once, like taking a shower and washing dishes. They are much less expensive to install and maintain, although they do end up costing more each year in energy costs. Tank water heaters also tend to provide hot water more quickly than tankless systems. On average, a 30 gallon heater is good for a household of 1-2 people, a 40 gallon heater is good for 2-3 people, and a 50 gallon heater is good for 3-4 people. For a household of five or more people, an 80-gallon electric system or a 50-gallon natural gas or propane1 system should be sufficient.

Whole house systems require more power and a larger space to operate. They also tend to be more expensive than single point systems, although that cost is used to provide hot water to the entire house. A 1,500 square foot home system averages $600-$800.

Historically, single point systems were for tankless systems, although there are more options now. Single point systems tend to be more efficient because the water doesnt have to travel as far before reaching its destination, giving it a smaller chance of heating unnecessary water and water losing its heat as it travels through long pipes. Single point systems are smaller and less expensive, as low as $200-$400.

There is always a risk of a water heater leaking, which makes its location even more important. A water heater should be placed somewhere it wont cause major damage if it leaks, such as a storage room or garage. Water heaters need to be accessible for maintenance and should have 12-18 inches clearance on all sides.

Plumbers typically charge $45-$65 per hour and can typically install a water heater in a day (6-8 labor hours), for a total labor cost of $270-$520. Water heaters that are difficult to access or that are in tight enclosures can take an extra 2-3 hours ($90-$195) to install.

Homes with solar water heaters may need a backup hot water system for when the solar system cant get enough sunlight to work. On average, a standard backup system averages $200-$300.

Flat plate solar collectors collect more heat and are a good option for larger heating projects, such as heating swimming pools. They start at around $7,000.

Energy-efficient water heaters come in a variety of types and styles. On average, a water heater with an energy-efficient label costs 10%-20% more.
