The cost of installing a water heater from Home Depot depends mainly on the type available and location. But, on average, one can spend between $1000 and $3000 depending on the style. This cost does not include the purchase price since the different units have varying costs.
What are the different types of water heaters and their costs?
There are different styles of water heaters, each having specific purchase and installation costs. The table below shows the estimated costs of this equipment;

Hybrid water heaters (Heat pump water heater)
A Hybrid (also known as a heat pump) water heater does not generate heat, and it helps keep the electricity cost low. This appliance uses the heat in the ground and air to warm up the water. Although the heaters take up a lot of space, they can use up to 60 percent less electric energy than traditional water heaters.
This appliance is suitable for people living in warmer areas like Arizona but may not be ideal for colder places such as Alaska or Minnesota.
Tankless water heaters
A Tankless (on-demand) water heater is ideal for places with many people living together as it can supply hot water continuously. This appliance uses super-heated coils, which fill and heat water quickly. The water heaters come in varying sizes to choose from and are perfect for those using natural gas in their home.
Although the heaters have a higher price tag and may be difficult to clean, they are environment-friendly. s
Conventional storage tank water heater
This water heater is the most common and famous, and it features a central storage tank for holding water. Different capacities of this tank are available, and you can choose depending on your family size. This equipment is insulated and uses two valves, i.e., pressure control and temperature control valves.
These valves become active upon reaching specific numbers. For example, when the water temperature in the tank reaches 120-degrees, it releases heat to cool down. The tank is among the most affordable and easy to install. For proper maintenance, the tank needs cleaning two times a year.
Condensing water heater
Condensing water heater utilizes unused gas vapors to heat the water. It is ideal for those families that rely on natural gas for fuel as it does not use a lot of energy. This appliance comes in different sizes, and it also has a water tank like other options.
Solar-powered water heater
This type of water heater is one of the most energy-efficient, especially for people who have solar panels in their homes. It is also an excellent option in places with much sun, but it may need a backup energy source for cooler days.
What does water heater installation include?
The installation of a water heater includes;
- Delivering the new unit and hauling away the old one
- Disassembling and removing the existing unit
- Assembling and securing the new water heater in the exact area as the old one
- Linking the water heater to an available code-approved electrical, vent, water, and gas supply line. The cost does not include upgrading to meet new code regulations.
- Testing the water heater for cycle and leak
- Inspecting for proper operation and going through care instructions
- Cleaning up any installation-related dust and debris
What is the cost of replacing a water heater?
The cost for replacing a water heater with a new one ranges between $811 and $1566. But, the national average is $1176, although this price depends on the size and type of the water heater. The overall water heater replacement cost will also be affected by labor and installation costs. But, the labor cost for installing an average replacement water heater ranges from $150 to $800 but most plumbers give a flat-rate quotation that includes labor and materials.
If you hire a professional plumber, it may cost between $45 and $200 per hour, while an electrician charges between $50 and $100 per hour.
What are the factors that affect the water heater replacement costs?
Several factors influence the cost of water heater replacement, including;
The style of the tank
There are two main styles of water heaters, namely tankless and tank styles.
A water heater with a container (tank) holds about 30 to 80 gallons of hot water. Most water heaters installed in the US (about 90%)are tank-style heaters. Tank-style water heaters cost ranges from $700 to $2000 (including materials and labor).
This type of water heater supplies a continuous stream of hot water using a series of super-heated coils. These tanks are hard to install and, therefore, cost more in labor and purchasing than their tank-style counterpart. The average cost for this type of tank ranges from $1000 to $3000, including materials and labor.
Differences between the tank and tankless water heaters
From $700 to $2000
$1000 to $3000
Stores hot water in large volume
Endless hot water supply
Last between 8 and 15 years
It can last more than 20 years.
The home’s geographical location
A home’s geographical location impacts significantly on the overall fuel and water heater replacement cost. Climate changes can affect the amount of energy that the appliance uses. For example, in cooler regions, a lot of energy is used to heat water to a suitable temperature. On the other hand, in a warmer area, less energy will be used.
Size of water heater
The size of the water heater you are replacing also affects the cost of this process. Tank water heaters come in different capacities ranging from 20-gallons to 100-gallons, but the most common are 40-gallon capacities. A 30-gallon tank water heater cost between $270 and $900, while an 80-gallon one will cost from $1000 to $3000.
Water heaters are vented in two ways, i.e., power vent and direct vent. In the direct vent heaters, exhaust gases pass through the chimney or an exhaust pipe above the unit to the outside. This type of venting system may increase the replacement cost by about $500 to $1000 if one switches from electric to gas.
On the other hand, a power vent uses a fan or blower to push out the gases from home. This kind of vent heater will increase the replacement cost from $300 to $600 and an additional $300 to $500 for electrical and wiring tasks.
Type of water heater
All water heater types use either electricity or natural gas. Electric heaters are cheaper than those that use gas by about $100 to $200. While natural gas water heaters are highly-priced and not energy efficient, they are more preferred due to the high cost of electricity. However, for those living in small apartments or confined areas, electric water heaters are ideal.
Materials such as fittings, discharge pipes, pressure release valves, venting pipes, pipe thread compound, water and gas piping will influence the replacement cost. Depending on which materials are used, the price may go up or remain low.
Location of the system
The site of the appliance within your home will also affect the cost of replacing it. For instance, if the water heater is in a hard-to-reach location such as a basement or attic. If the installers have to move the appliance a flight of stairs up or down, it may attract additional charges.
Removing the old water heater
It may cost between $100 to $500 to remove an already existing water tank. This cost depends on the size and location of the unit and the rate per hour of the contractor. A heater that is hard to access will cost more to remove than one which is easily accessible.
Depending on the type of water heater and the amount of work involved, replacement permits range from $100 to $500. You may ask your contractor to get the license for you or obtain it yourself.
You may be required to part with $500 to $1500 for electrical wiring fees. If you change from a gas to an electric water heater, it will add an extra $200 to $500. Electric appliances cannot use existing lines and require their circuit.
Gas and water line installations
Water heater replacement costs can also go up if one is changing from one fuel source to another. Installing a water line may cost between $350 and $1000, while a gas line installation cost can range from $250 to $800. These costs may even be higher if you prefer the gas line to reach the water heater location.
Replacing the plumbing system
During a water heater replacement, it is necessary to consider the current state of the plumbing system. If there are pipes that need replacing or moving some to a different location, it will increase the cost.
The cost of installing a water heater from Home Depot depends on various factors such as the type, size, location, and venting system. These charges may be low or high, depending on the location of the appliance. Whether the plumbers and electricians charge a flat rate hourly basis
will also impact the cost.
One must look at their budget and the number of people in the household to decide what is best for them.
