Upgrading your home to a tankless hot water heater has several major advantages. Tankless hot water heaters are energy efficient, saving you money on energy bills and reducing your carbon footprint. They also have unlimited hot water supply; they will never run out of hot water like traditional tanks do.

Tankless water heaters are 24%-34% more efficient than traditional tanked water heaters for typical homes(data is based on the U.S. Department of Energy Tankless Water Heaters Are More Energy Efficient). When you start to multiply these energy savings by comparing the two water heater types, the overall energy savings of the tankless water heater grows significantly. When taking energy efficiency into consideration tankless water heaters are the most energy-efficient solution. The graph from the U.S. Department of Energy illustrates the comparison well.

Tankless hot water heaters can be characterized as offering virtually unlimited hot water. When operating optimally, they can provide a continuous supply of hot water without depletion. The consistent flow of hot water hinges on several variables, including selecting an appropriately sized unit for your residence and ensuring precise installation with ample energy supply, enabling the tankless system to deliver an uninterrupted stream of hot water. In a direct comparison of capacity, tankless hot water heaters surpass conventional hot water tanks, consistently maintaining the temperature of your water and outperforming their tanked counterparts.

In terms of their design, tankless hot water heaters exhibit a more streamlined and space-efficient form compared to their tanked counterparts. Their compact nature allows for flexible installation, placement, and customization in more convenient spots, preventing obstruction of access or utilization of storage areas in your home or garage. In contrast, conventional hot water tanks tend to be sizable and consume a significant amount of room. If optimizing storage space is a consideration, the compact design of a tankless water heater presents an ideal solution.

Tankless water heaters have the potential to endure for approximately twice the duration of tanked water heaters. The conventional stationary hot water tank typically maintains an average lifespan ranging from 10 to 15 years. In contrast, the innovative tankless water heaters are engineered with an average longevity spanning between 12 to 30 years.
