Will a tankless water heater deliver instant hot water at all my faucets and showers?

Tankless water heaters are sometimes called instantaneous or on-demand water heaters. This has led to some confusion for people who have installed whole house tankless water heaters expecting to have instant hot water as soon as they turn on their shower or faucet.

While the tankless water heater is heating the water as soon as you turn on your faucet or shower, the cold water that existed in the pipes between the faucet and the water heater still needs to be flushed out, just like with any whole-home water heater. So, when you turn on the faucet, there will be a small amount of cold water first.

If you desire instant hot water for your shower or faucet, you can install a smaller-point-of-use tankless water heater designed to deliver hot water to a specific fixture.
