What is the downside of a tankless water heater?

How much does it cost to replace a hot water heater with a tankless?

Can you run out of hot water with a tankless water heater?
With a tankless system, there isn’t a supply of hot water that can be depleted. Instead, the water heater heats up water as there is a demand for it. It will keep doing this as long as there is demand – and that means you won’t run out of hot water!
Is it worth switching to a tankless water heater?

Can I install tankless water heater myself?
Installation. While it is possible to install your own tankless water heater, it’s not a job for inexperienced do-it-yourselfers. There are a number of different sizes and styles of tankless water heaters, including propane, natural gas and electric, along with single-room or whole-house sized models.
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.
