What is the downside of a tankless water heater?
Why avoid a tankless water heater
A tankless water heater can only heat so much water at a time. If you demand more hot water than the unit can generate—for instance, if you run the dishwasher, washing machine and shower at the same time—the temperature of the water will fluctuate since the heater is trying to provide for all three locations at once.

The commonest complaint we get with tankless water heaters is that they don't seem to provide hot water as quickly as expected. Like most tankless water heaters, if your water heater does not have a buffer tank or a recirculation pump, it may take a minute or two for the water to heat up before it comes out of the tap.

Do tankless water heaters increase electric bill

How many showers can a tankless water heater run
two showers
A unit heating more than 7 gallons per minute can typically handle two showers and a large appliance. *Important to note: Tankless units do not literally provide “instant hot water” – the hot water still takes time to flow from the unit to the faucet.

Do you have to flush a tankless water heater every year

Is it better to install a tankless water heater inside or outside
Outdoor installation helps you avoid much of the hassle of indoor installation. You don't need to worry about ripping out a section of the drywall, running the gas line over to the unit or running the exhaust outside. The unit is more accessible on the outside of the building for its yearly maintenance.
Do you always have hot water with a tankless water heater
When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water.
