Water heaters come in two main styles: tank and tankless. A tank water heater, as the name implies, keeps hot water ready to use in a large tank that holds anywhere from 30 to 80 gallons. More than 90% of water heaters installed in U.S. homes are tank-style.
Tankless water heaters cost two to three times more than standard tank heaters. They’re harder to install and will run you more in labor costs. The advantage with these small, suitcase-sized units is that they deliver an endless supply of hot water whenever you need it through a series of super-heated coils. You might hear them referred to as “on-demand” heaters.

All types use either gas (natural or propane) or electricity. On average, natural gas fired units cost $100 to $200 more than electrical types. The internal heating comes either from an electrical coil, much like a stove top coil, or via a gas pilot light. Although natural gas units cost more up front and they’re less energy-efficient, the high price of electricity in most parts of the country still makes gas the cheaper long-term choice. However, electrical types, whether tank or tankless, make better choices for small apartments or confined areas since they don’t require make-up air or venting.
Propane and oil-fired water heaters both fall on the expensive end of the spectrum at $1,000 to $3,000 for the unit alone. Propane and oil-fired types offer an alternative to electricity and natural gas for rural and off-grid homes.
Power venting a water heater costs about $500 to $1,000 more than a passive or direct vent system.
Power venting: Adds $300—$600 to the unit’s price. Plus, you’ll add an additional $300—$500 for wiring and electrical. This system uses a powered fan to push exhaust air out of your home. Natural and propane gases create carbon monoxide as they burn, creating a potentially serious health hazard if not vented properly.
Direct venting: Adds $500—$1,000 only if you’re converting from electric to gas. This system is based on the idea that hot air rises over the cooler surrounding air. As the gas burns, air heats up and vents out of your house through a vent stack above the unit.
Various factors affect the cost of replacing or installing a new water heater. Consider each factor and what’s best for your needs.
Although tankless water heaters are smaller than tank-style units (which hold 30 to 80 gallons of water), they are more difficult to install. You’ll pay more for labor as installation can take up to 10 hours. However, a tankless water heater can save you up to 25% on utilities.
How many gallons a water heater tank holds (30 to 80 gallons) determines the size and the price increases with size. For most homes with up to two people, a 40-gallon water heater will suffice and costs around $320 to $1,600. For homes with five people or more, you may want to consider a 75-gallon (costs about $900 to $3,000) or an 80-gallon tank (costs about $1,000 to $3,000).
Water heaters run on electric or gas power sources, with gas options costing around $100 to $200 more than electric ones. Gas options are also less energy-efficient; however, gas is less expensive in the long run because of the high price of electricity.
The setup and location of the water heater in your home will directly impact the cost of labor. For example, if your water heater is in the basement or a corner of the attic that is difficult to reach—and a pro has to carry the unit up and down multiple stairs—it could drive up the installation cost.
The two ventilation styles for water heaters are direct vent and power vent. A power venting water heater costs about $500 to $1,000 more than direct venting units and requires additional wiring and electrical for the exhaust fan. Keep in mind that a direct vent requires a vent stack and can add around $500 to $1,000 to the overall cost if you’re converting from electric to gas.
Depending on the type of water heater and the location, installation requires materials like venting pipes and connectors, pressure release valves, discharge pipes, piping for water and gas, pipe thread compound, solder, and fittings. A pro may need to use more materials for complicated installations.
"There are many high-efficiency options on today's market that are worth a look, especially when you realize that water heaters are the second highest source of energy consumption in the home."

High-efficiency water heaters cost an average of $1,000 to $3,000 including the unit and labor. They’re anywhere from 100% to 300% more efficient than conventional water heaters. They use a combination of factors to create better energy efficiency, which include:
Better insulation
Smart controls with leak detection and protection alerts for connected devices
Heat pumps (discussed in the next section)
Plastic tanks
Solar water heater installation costs $1,700 to $5,200 on average but can skyrocket to $13,000 or more. Some people supplement their system with a solar tank or tube style heater. While these are very expensive, you will save on energy over time.
You’ll pay in the range of $1,200 to $3,500 for most hybrid heat pump water heaters. This price includes both the materials and labor. They’re the most efficient style of tank heater and the most expensive. They use a heat pump to pull heat from the surrounding air and transfer it to the water in the tank via a compressor and coils.
Heat pumps are large units, requiring as much as 7 feet from clearance from floor to ceiling, plus up to 1,000 cubic feet of surrounding air space, so they‘re not a good choice for small houses and apartments.
Indirect water heaters cost $800 to $1,500 on average. This extremely efficient choice consists of a tank that pulls heat from a nearby boiler or furnace, rather than relying on an independent heat source. The systems can be fired by gas, oil, propane, electric, solar energy or any combination of these.

The costs above are estimates for the unit only. They are for the common 30- to 50-gallon capacity units and do not include installation, transportation or other additional expenses.
Labor costs to install a standard water heater typically range from $150 to $800. Most plumbers quote a flat rate that includes the materials and labor but if you already bought your own unit, you may pay hourly rates for your pro. Hiring a plumber costs $45 to $200 per hour and electricians cost $50 to $100 per hour.
Replacing a water heater usually costs $500 to $1,800 for a replacement of the same style and size. Other costs, including permit fees and carpentry work, can add anywhere from $50 to $1,500 or more.
Converting from one fuel source to another often includes one or more of the following:
Adding electrical wiring fees: $550—$2,300
Water line installation costs: $350—$1,900
Gas line addition price: $275—$825
Permits: $100—$1,500, depending on the type and extent of the work you’ll do.
Expansion tanks: $40—$350. These are often required in new construction or when updating.
Carpentry work. You might need to frame a new wall, enclose or open a space or simply add drywall to a utility closet.
Framing a wall costs: $200—$400.
Drywall installation costs: $1,000—$2,900.
It will cost you $200 to $500 or more to convert from gas to electric. The total cost comes from running a new electrical circuit. Electric heaters require their own dedicated circuit so don’t try to put them on an existing line.
Water heater permits cost $50 to $500 depending on the extent of the construction needs. You can pull a permit yourself or have your installer do it and include it in their overhead.
A water heater expansion tank costs $40 to $200 with labor adding another $50 to $150. Most come with a little extra space for fluid expansion as it heats up. It’s usually required by code with new construction or when upgrading your current system. Without that space, the hot fluids build up pressure which can lead to pipes bursting.
Removing your current water heater costs anywhere from $100 to $500. The bill depends heavily on the hourly rate of your contractor. If the unit is hard to access or difficult to remove, expect to pay more for removal.

*May require two or more parallel units or separate units for point of use, such as a dedicated one for each bathroom, shower or appliance. For a detailed estimation you’ll need more information:
Tank style heaters: find your FHR (First Hour Rating) or the peak-hour hot water demand and your tank's recovery rate.
Tankless: determine the flow rate of each appliance, fuel source and rise in temperature needed.
About 90% of hot water heater installations are the result of a sudden failure, according to the American Council for an Energy-Efficient Economy. You can avoid the stress of that situation by watching out for the following warning signs that your water heater is nearing its end of life:
Water is rusty or discolored or there’s a strange metallic taste. This means the anode inside has failed and the heater is corroding.
Water isn’t heating up enough. Likely an issue with the main heating element.
Not getting hot at all. While this could indicate that the pilot light is out or the circuit breaker has been tripped, it can also indicate a failure of the heating system.
Loud pops and cracks. These noises indicate that the heating element is failing.
Leaks. This indicates that a major failure is going on internally. Shut off the electricity or gas to the system and let it cool down before replacing it.
Over 10 years old. It’s nearing the end of its life expectancy.
When it comes time to replace your unit, it’s best to call a professional. This way you can be sure that everything has been done safely and to code.
A water heater is a must in your home. As technology advances, the efficiency of these systems will increase. It’s tempting to save a few hundred by installing one yourself, but you’ll need to deal with pipes, gas lines, or electricals.
You’ll also need a permit and inspection. If anything fails, the cost of repairs, cleanup or updating an improper installation might end up costing more than hiring a pro in the first place. If you want to save money on this project, look for multiple water heater installation companies near you. Compare rates, reviews, and get multiple quotes before you hire.
Other ways to save money on this project include looking for rebates and special offers for a water heater replacement from your utility company. Remember, don’t buy a unit that is too big for your household size. Not only will you pay more for the unit, but you’ll also pay more for energy costs over time. Choose a replacement unit that is the same size and type as your old one to keep the installation simple, and choose the fuel type that works best with the existing gas lines in your home.
Small families and studio apartments can often use a 20-gallon electric tank or tankless water heater (if the apartments are on individual units).
An expansion tank is a safety system for water that expands when it heats up. Most have a little room inside for expansion; however, any system can fail. In this case, the expanding water flows into the expansion tank rather than your pipes. Many codes now require installing one with new construction. Without a safe place for the expanded water to go, in a worst-case scenario, your pipes burst from the pressure.
Water heater costs range from $150 to $700 per year. It makes up 14% to 20% of your total household energy use.
Water heater repairs cost $225 to $1,000. The actual bill depends heavily on what work you have done, if you have a tank or tankless unit, and the fuel source.
A tank style water heater lasts 8 to 15 years. Tankless has a 20+ year lifespan.
When your hot water runs out quicker than normal or it begins to taste metallic, you know your water heater is going out.
It takes about 20 to 30 minutes to completely drain a 40-gallon water heater.
A 50-gallon water heater can take anywhere from 1 to 2 hours for electric or 30 to 60 minutes for gas to heat water to 120 degrees.
