$850 \u2013 $4,000+ Installed<\/h2>\n<\/p>\n
The cost of a professionally installed tankless water heater starts at about $850 for an electric point of use model and can rise to $4,400 for a whole-house gas tankless unit. Most homeowners pay $900-$1,400 for electric and $2,500-$3,800 for a gas-fired whole-house model installed. Retail tankless water heater prices for DIY are below.<\/p>\n<\/div>\n

Average Cost of Tankless Water Heater Installation<\/h2>\n
Expect plumbing contractor estimates of about $950 for each point of use electric water heater you have installed. When you have 2-4 electric units installed, the total cost is similar to having a single whole-house gas tankless water heater installed for a national-average cost of $3,400.<\/p>\n
Prices include the unit, installation supplies including wiring and venting materials where needed and the cost of labor to do the work.<\/p>\n

While operating costs for electric are much higher than for natural gas units, installation costs are significantly reduced because they don\u2019t require exhaust venting.<\/p>\n Gas tankless water heaters<\/strong> are always sized to serve an entire home, or 2-5 locations at once based on flow rates measured in gallons per minute, or GPM.<\/p>\n In addition to on-demand hot water, tankless units save floor space and are energy efficient. Many last longer than traditional tank-style water heaters, because it is usually the tank that fails from corrosion or leaks.<\/p>\n Most gas-fired tankless heaters burn natural gas, but propane versions are available in many models.<\/p>\n Popular gas models have a maximum delivery of 7.0 to 12.0 gallons per minute when the incoming water is about 70 degrees. But in most of the country, underground temperatures where pipes are running are usually 45-65 degrees. As a result, a unit with a maximum GPM of 10.0 might only deliver 4.5-7.0 GPM, so ground temperatures must be considered when sizing the gas water heater for your home. This issue is avoided with electric units, most of which deliver between 0.6 and 5.0 GPM.<\/p>\n Gas water heaters on this page of Business Finance News include venting an indoor unit \u2013 outdoor units are available that require little-to-no venting, but they aren\u2019t recommended in the coldest climates.<\/p>\n Expect an additional cost to run a gas line to the installation point or an electrical circuit and wiring. If a gas line is in place but doesn\u2019t have a shut-off valve, you\u2019ll probably have to install one on during this project to bring the plumbing up to code.<\/p>\n Cost Tip:<\/strong> While you will reduce energy bills in the years ahead with a tankless water heater, the lifetime cost will be higher than if you buy a traditional tank style water heater due to the higher upfront equipment cost of a tankless model.<\/p>\n Whether you spend less than $600 or more than $4,000 on your tankless hot water heater depends on which options you choose.<\/p>\n If you DIY or source your own water heater for a plumber to install, here are costs for units and the most common installation supplies.<\/p>\n Pro installation is often handled by a plumber or mechanical contractor.\u00a0 A licensed plumber or contractor will charge anywhere from $50 to $150 per hour for their labor.\u00a0 The Home Depot gives $3,500 as the average total cost of a gas tankless model, which is the upper limit of the range given by HomeGuide. For electric models, Homewyse gives a per-unit cost average of $1,400 for a whole-house 5.0 GPM model.<\/p>\n These price estimates are consistent with our pricing, and a good chunk of that is the labor side of the equation \u2013 $800 to $1,200 per Remodeling Expense for most models, but we\u2019ve seen higher for complex gas unit installations.<\/p>\n The installation process will take 3 to 6 hours to complete.\u00a0 If you need to run electric lines or run a gas line your installation take longer and will be more costly.\u00a0 See Costs of Related Projects to learn more.<\/p>\n If you need a gas line for your tankless water heater you will have to pay by the foot and hire a plumber for the job.\u00a0 You can expect to pay between $20 -$26 dollars per linear foot for the new gas line for your tankless water heater.<\/p>\n Cost to have a circuit breaker installed: <\/strong>If your tankless water heater requires its own electrical circuit, cost will range from about $130 to $280 for the installation of the circuit breaker. Running wiring to the water heater will cost another $200 to $350 for time and materials.<\/p>\n How much does it cost to run a gas line? <\/strong>The average cost is about $24 per linear foot, though most contractors will have a minimum fee for the work of at least $100. Most jobs range from $150 to $400 based on the length of the line.<\/p>\n Cost to replace a water heater: <\/strong>Compare the cost of a standard water heater in this Costimate, or cost estimate.<\/p>\n On some projects we like to say, \u201cif you\u2019re asking whether DIY is a good idea, then it probably isn\u2019t.\u201d<\/p>\n We recommend pro installation for anyone without experience connecting gas lines and venting combustion gases, since they contain carbon monoxide. Dangerous risks also come with installing an electrical circuit and wiring an electric tankless water heater.<\/p>\n In short, there is potential for problem \u2013 and most can be avoided with pro installation.<\/p>\n The bottom line is that hiring a professional will also help ensure that your project meets code, avoiding delays and hassles, and you won\u2019t have to rely on the plumbing inspector to make sure your water heater will operate safely.<\/p>\n<\/div>\n <\/main><\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":" $850 \u2013 $4,000+ Installed The cost of a professionally installed tankless water heater starts at about $850 for an electric point of use model and can rise to $4,400 for a whole-house gas tankless unit.
