The global tankless water heater market is driven by consumers’ concern over sustainable use of energy, technological advancement and increasing number of residential units. Tankless water heaters also known as instantaneous water heaters or demand technology water heaters, are the source of hot water when needed. states that tankless water heaters typically produce 2 to 5 gallons (7.6 to 15.2 liters) of hot water every minute. Tankless water heaters powered by gas have higher flow rates than those powered by electricity. However, there are times when even the largest gas-fired model is unable to provide enough hot water for numerous simultaneous usages in large households. 

The market will expand as a result of shifting customer preferences toward smart appliances and significant investments in R&D, including the integration of smart technologies and new product improvements.

Additionally, it is anticipated that product development would offer up new possibilities for market expansion. For instance, EcoNet Smart Technology, which supports Wi-Fi connectivity, and other features offering system control, cost savings, and protection are included in Rheem's Prestige models. The development of carbon-neutral buildings included with the growth of smart cities and commercial infrastructure, are all fueling the market. Soon, market growth is predicted to be driven by ongoing technological advancement.

Sales of tankless water heaters are expected to increase as companies develop services and goods that are convenient and interoperable. In this market, reasonable pricing, ease of use, and rising acceptance may be seen.

The market for tankless water heater systems will also experience considerable expansion as traditional water heater units in commercial settings like hospitals, hotels, restaurants, beauty salons & spas, etc. are increasingly replaced by tankless water heating technology.

Energy Saving Properties Are Fueling the Market Growth

As per, demand technology water heaters can be 24%–34% more energy efficient than traditional storage tank water heaters for households using 41 gallons or less of hot water daily. For homes consuming a lot of hot water roughly 86 gallons per day, they can be 8%–14% more energy efficient. If a demand technology water heater is installed at each hot water outlet, energy can be significantly saved. The average amount of electricity bill saved by a tankless water heater is around USD100-200.

Long Life Expectancy is Fueling the Market Growth

A tankless water heater is more expensive to buy initially than a traditional storage water heater. Still, they often live longer and have lower operating and energy costs, making up for their higher original cost. The majority of tankless water heaters have a lifespan of over 20 years. They also feature pieces that are simple to swap out, adding many more years to their lifespan. Storage water heaters, on the other hand, endure 10 to 15 years.

Technological Advancement is Aiding the Market Growth

With consumers becoming more aware of the cutting-edge technologies available on the market, manufacturers are now concentrating on developing innovative products. For instance, Rinnai, a top producer of tankless water heaters, has integrated Amazon Alexa's compatibility with Rinnai products, enabling consumers to ask Alexa to switch on circulation, allowing the tankless water heating system to function. Additionally, it offers Google Wi-Fi connectivity for compatible products, enabling users to track the effectiveness of their tankless water heater recirculation system.

High Efficiency Rate of Condensing Water Heater is Driving the Market Growth

Over the anticipated term, a high growth rate is projected for the condensing segment. Condensing tankless water heaters, which are more prevalent in emerging nations than non-condensing tankless water heaters, are more energy efficient.

Key producers of water heaters will benefit from the high market concentration resulting from various government and corporate sectors concentrating on creating power plants that utilize renewable energy sources, such as solar and wind.

High Installation Cost is Hindering the Market Growth

Tankless water heaters are costlier to install than traditional water heaters. However, a variety of elements play specific roles in proper installation. These elements include the technology of fuel used, the environment, the needs of the local construction codes, and safety concerns, particularly those relating to the operation of gas-fired water heaters. Tankless heater installation typically costs between USD4,500 and USD6,500, with an average cost of roughly USD5,500. (Including the water heater, warranty, and tune-ups). The price of the tankless installation without the unit can range from USD1800 to USD3500, with an average of USD2650.

Labor rates are among major factors. An electric tankless water heater will probably cost somewhere around USD2,500, according to data from Energy Sage. This price covers both the equipment and the installation. The typical pricing point for a gas-powered system will be closer to USD3,500.
