How many tankless water heaters does a house need?

For larger households that typically use more than 85 gallons per day, two tankless systems, or the largest available model, are likely needed. For smaller households that use under 40 gallons per day, one unit should suffice.

Installation is expensive because the unit needs a bigger gas supply than a conventional water heater does, and it needs to run its own exhaust flue to the exterior. Installation costs can vary widely, depending on the location of the flue and the gas supply. The unit itself costs between $800 and $1,000.
