This type of water heating system can be useful for large families or for homes with larger hot water demands - for example homes with a soaking tub or spa system are often good candidates for a tankless system. While traditional storage water tanks are compared based on gallon capacity, recovery rate and first hour rating, tankless hot water heaters are compared based on flow rate. As long as the home uses hot water at a flow rate below the tankless heater's maximum flow rate, there is endless hot water.

Important to note: Tankless units do not provide instant hot water as hot water still takes time to flow from the unit to the destination. Tankless water heaters on average will save 20% to 40% on energy use compared with storage tank type water heaters. The most efficient tankless water heaters have a 92% to 95% efficiency compared to traditional gas storage tanks that operate at a maximum 62% efficiency. Tankless units typically operate at over 80% energy efficiency. Tankless water heaters save most energy because water is not constantly heated, cooled and re-heated like within a storage tank. Flow rate is the most important factor in sizing your tankless water heater.Tankless units heat water on demand (when you open your faucet) unlike traditional storage tanks that heat when the tank temperature drops below a set point.

Tankless water heater sizes are measured by their per minute flow rate rather than by their gallon capacity. Most tankless water heater manufacturers offer several models to meet different flow rate needs. Flow rates for most major brands range from four to eight gallons per minute. Typically, the smaller four to five gallon per minute water heaters are suitable for smaller apartments and small one bathroom homes. For single family residences with two bathrooms or more, we strongly recommend installing a six to eight gallon per minute unit. These tankless water heaters are designed to service two or three applications at the same time. For very large homes, restaurant or other commercial applications there are many other options including installing multiple tankless units in series.
