Tankless vs. Tank Water Heaters

While tankless water heaters cost more than old-fashioned tanks, they offer a huge number of pros vs. cons of installing a tankless unit. When comparing a tank style and tankless water heater, there are several key differences to consider:

Continuous Hot Water

Unlike tank water heaters that store a limited amount of hot water, a tankless water heater provides hot water on demand. This means you never have to worry about running out of hot water, regardless of your usage patterns. Rinnai offers Smart-Circ™ Intelligent Recirculation™, which learns your hot water usage pattern and schedules your recirculation accordingly.

Energy Efficiency

A tankless water heater is more energy-efficient than a traditional tank model. Since it only heats water when needed, it eliminates standby heat loss, resulting in lower energy consumption and reduced utility bills. Thanks to its enhanced combustion design, Rinnai has super high efficiency and makes for a better experience when your energy bill comes due.

Space Savings

Tankless water heaters have a compact design and take up significantly less space compared to traditional tank models. This makes them an ideal choice for homes with limited space or for those looking to maximize their usable area. Plus, no more storing huge amounts of water that could potentially leak all over your floor.


Tankless water heaters tend to have a longer lifespan compared to tank models. With proper maintenance and care, a tankless unit can last up to 20 years, whereas traditional tanks may need replacement every 10-15 years.
