What is the downside of a tankless water heater?
The primary disadvantage of on demand or instant hot water heaters is the upfront cost. The smaller units that you often see won’t produce enough hot water to serve most households. They’ll only serve one faucet at a time—a problem if you want to shower while the dishwasher is running.
How much water does a tankless water heater save?

Can you run out of hot water with a tankless water heater?

Why is tankless water heater installation so expensive?
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.
