The growing government efforts to promote environmentally friendly water heaters are expected to propel the growth of the tankless water heater market going forward. Government efforts refer to the actions, initiatives, and programs undertaken by a government to address various issues, achieve specific goals, and meet the needs of its citizens. Governments can encourage the adoption of energy-efficient tankless water heaters over traditional tank-based models by establishing standards and regulations for appliances while also implementing incentive programs aimed at both consumers and manufacturers to promote the uptake of tankless technology. For instance, in July 2023, according to the Department of Energy, a US-based government agency, the U.S. Department of Energy put forth new energy efficiency standards, aiming to achieve annual savings of $11.4 billion for consumers on their energy and water bills. Aiming to save $198 billion for Americans and reduce 501 million metric tons of CO2 over 30 years, the proposed regulations, which take effect in 2029, are equal to the yearly emissions of 63 million households, or roughly 50% of all dwellings in the United States. Therefore, the growing government efforts to promote environmentally friendly water heaters are driving the growth of the tankless water heater market.

Major companies operating in the tankless water heater market are developing innovative products, such as electric tankless water heaters, to better serve customers with advanced features. Electric tankless water heaters are on-demand water heating systems that use electricity as their primary source of power. For instance, in January 2023, Bosch Thermotechnology, a Germany-based provider of heating and hot water products, launched the Tronic 4000 C and Tronic 6100 C. The Tronic 4000 C stands out as one of the most compact and energy-efficient electric tankless water heaters available, specifically designed for point-of-use and under-sink installations. Remarkably small at only 8.5” X 13” and weighing just 4.4 lbs., it can be conveniently wall-mounted directly under the sink. Operating solely on electricity and lacking a water-holding tank, the Tronic 4000 C requires no venting and entails virtually no maintenance, making it an exceptional choice for users seeking space-saving and hassle-free solutions. In contrast, the Tronic 6100 C introduces a distinct feature by providing on-demand hot water for entire households. Bosch, with the Tronic 6100 C, seamlessly combines energy efficiency and convenience into a beautifully streamlined, easy-to-install design that is both compact and lightweight, catering specifically to whole-house applications and ensuring continuous and efficient hot water supply.

A tankless water heater is a specific type of water heating system that heats water on demand without requiring a storage tank. This system operates by utilizing either an electric element or a gas burner to heat water as it flows through a pipe to the unit. The key advantage of a tankless water heater is its ability to provide a continuous and nearly limitless supply of hot water, as it heats the water directly at the moment it is needed, eliminating the need for a reservoir.

Tankless water heaters come in two main types such as condensing and non-condensing. A condensing tankless water heater is designed to recycle the excess heat generated during the water heating process, resulting in increased fuel efficiency. These water heaters utilize various energy sources, including electric and gas, and find applications in various settings such as residential and commercial environments. Condensing tankless water heaters are particularly valued for their ability to optimize energy usage and enhance overall efficiency in heating water.
