Hot Water Heaters and Tankless Water Heaters

What is a tankless water heater?

A tankless water heater, also known as "On-Demand Water Heater", will only heat the water when there is demand, or flow, through the unit. There is a heat exchanger inside the unit with a burner, small passageways, and some type of flow detection switch. The unit triggers the burner and with the smaller water waterways the water is quickly heated to the desired temperature before leaving the unit when the flow starts. As there is not a large tank of water that is constantly being heated, these are called tankless water heaters.

How long will a tankless heater take to heat up?

Typically, the start up of the unit happens in just less than a minute. It varies on how far the tank is from the fixture in need of the hot water.
