Tankless water heaters, commonly referred to as demand-type or instantaneous water heaters, deliver hot water only when it is required. They don't have the same standby energy losses as storage water heaters, which means they can save you money. Here you'll learn the basics about tankless water heaters, including how they operate, if they're good for your house, and how to choose the best model.

tankless Water Heater Instalation Cost


They are more compact than traditional storage heaters, may be mounted on the wall, and do not take up any floor space. Their size makes them particularly appealing in houses with limited square footage. 

They may be able to assist you in lowering your energy costs. According to the US Department of Energy, heating water accounts for around 30% of a family's energy expenses. Using a tankless water heater can cut these expenditures by up to 50%, saving an average of $80 each year.

They're long-lasting and less likely to collapse, resulting in potentially disastrous flooding in your home. Tankless water heaters have a lifespan of 20 years or more, which is roughly double that of traditional water heaters.


How much does it cost to install a tankless water heater? The newest price;

Installing a tankless water heater costs $2,500 to $4,500 on average in the United States.

Installing a 150,000 BTU tankless whole-house gas type costs the average homeowner $2,811. For a single-point installed 240v electric tankless type, the project's low cost is $1,058. A whole-house solar system with an 80-gallon capacity costs $6,698 to install. 

Tankless Water Heater Installation Cost California

In California, the cost of installing a water heater can range from $1,000 to $7,500.

Of course, the price you'll pay for your individual installation is determined by a variety of factors, including the type of water heater you choose to install, the size/capacity of the water heater, the water heater's efficiency, the difficulty of installation, and the contractor you choose.

Tankless Water Heater Electric Installation Cost

The average cost of an electric tankless water heater is between $450 and $1,500. This style is widely available and is one of the most popular among homeowners. It is low-maintenance and environmentally beneficial, as it simply requires energy. This heater type is difficult to find in outputs more than 7 to 8 GPM. Consider a tank-style unit if you have larger needs and rely on power. If you wish to stay tankless, you'll need to switch to a different fuel.

Tankless Water Heater Gas Installation Cost

A gas tankless hot water heater costs between $500 and $2,000 on average. Tankless natural gas variants are widely available and ideal for use in cold areas. There is no need for the homeowner to purchase oil or pay a higher power bill. Electric tankless heaters cannot produce as much GPM as gas tankless heaters. Natural gas tankless heaters that can handle 15 or 20 GPM are readily available. This is perfect for households with higher-than-average hot water needs, as well as those in frigid areas. 


Electric tankless water heaters are less expensive than gas models. Installation is simpler and less expensive, and maintenance is often easier than with gas types. However, only a few have the capacity to supply several outlets at the same time.

Gas units come in a wide range of models and sizes for both residential and commercial use, with outputs ranging from 130,000 to 380,000 BTUs. Increased BTUs equates to more heating capacity. Keep in mind, however, that most traditional gas tank water heaters were not designed with a tankless conversion in mind when they were built. As a result, your home's gas piping, meter, and main line to the meter may be inadequately proportioned, necessitating costly reconfiguration and installation. Electric units do not require a proper ventilation system, whereas gas units do.

The overall energy efficiency of a tankless water heater is measured using an energy factor (EF) rating for both gas and electric types. The U.S. Department of Energy created the test processes that led to this EF rating. The energy factors of today's tankless water heaters range from.64 to.91 for gas-fired devices and up to.99 for electric models. The more energy factor a water heater has, the more efficient it is. 

A tankless electric unit will most likely enough for a household of one or two persons. A gas-fired tankless water heater is generally the best option for larger houses.
