Market Scope

Water Heater Market Dynamics

Key Market Drivers

Easy installation and maintenance

• Storage water heaters help to increase heating capacity by employing hot water storage tanks. Storage heaters are produced in a variety of sizes to meet market demand. Storage heaters are easier to maintain and repair than various forms of water heaters, and their installation is less expensive. Because storage heaters have a history of bursting, vendors are focusing on providing frequent water heater services.
• Additionally, storage heaters require space for the tank, thus manufacturers are focusing on making storage heaters smaller in order to address the space issue. It has also lately become increasingly common to use conventional storage heaters that operate on different fuels, such as fuel oil and natural gas.

Key Market Challenges

Higher installation and maintenance cost

• In order to meet the anticipated efficiency rate and calculate the total lifetime cost, which includes the initial cost, operating cost, and unit replacement cost, the water heating system must always be installed in compliance with the minimum applicable mechanical, plumbing, electrical, and other codes. Commercial water heater adoption is hampered by high upfront running costs brought on by greater costs for unit replacement or maintenance. The location of the water heater has a significant influence on this heater's running costs, particularly if the unit is inadequately insulated.

Key Market Opportunities

Increasing demand for instantaneous heaters

• Instant heating technology use is expected to rise as a result of its primary benefits, which include low standby losses and high supply output compared to traditional storage units. Increased demand for commercial applications due to sophisticated monitoring features, including Wi-fi among others, will favorably impact the size of the global water heater market.

Ongoing infrastructure investments

• The market for commercial water heaters is anticipated to increase at a rate of over 6% through 2027 as a result of the service sector's strong expansion and the continued construction of high-rise structures in new cities. The construction of new shopping centers and offices, hotels, and academic buildings will enhance the business environment. The market statistics will be enhanced by strict building efficiency regulations and rules paired with an increase in smart city development initiatives.
