Tankless water heaters heat water as it passes over an intense flame without the use of a storage tank.
Here are some considerations to keep in mind when sizing a tankless water heater.
- How many people are showering and when? Is there a “shower rush hour” in the morning or night?
- Do you have a deep soaking tub or whirlpool? How many gallons? Do you take a long showers?
- When are major appliances in use? Are the dishwasher and washing machine needed at the same time family members are showering? Most Americans are accustomed to staggering hot water use, so it is atypical to find a home where multiple hot water appliances are needed at the same time.
- How much hot water is needed to deliver the experience you want in your bathroom remodel? For example, is there enough hot water to fill a deep soaking whirlpool or to operate a vertical spa-type shower for any length of time?

Typically Yes – The BTU ratings of a tankless water heater are much greater than a conventional tank type heater.
