How a Tankless Water Heater Works

Because people are accustomed to water heaters using a storage tank, it’s initially hard to figure out how a "tankless" system works. But it isn’t too complicated.

A tankless system uses either natural gas burners or electric heating elements to transfer heat to water as it moves through it. There’s no need to store a supply of water: when a tap comes on somewhere in the house requesting hot water, the movement of the water through the water heater triggers the heat exchanger. When the request for hot water stops, the heating turns off. Essentially, a tankless water heater works "on–demand," which is why they are also called on–demand water heaters.

Why Consider a Tankless Water Heater Installation?

A tankless water heater installation provides a number of benefits for the right house:

  • Unlimited hot water: Because a tankless system has no supply of hot water that can be depleted and it will heat up more on demand, it can’t actually run out of hot water. The system can be overwhelmed if too many taps are on, but this shouldn’t be an issue if you have professionals size and install the right type of unit(s).
  • Energy conservation: A storage tank water heater must regularly heat up the water in the tank as it loses heat to the outside ("standing heat loss"). But a tankless water heater only needs to use energy when there is demand for hot water. It will use much less energy on average than a standard water heater.
  • Longevity: Tankless systems will outlast most tank water heaters. They also require fewer repairs.
  • Small size: If you’re looking to save space in your basement or garage, a tankless water heater can help. Most can be mounted on the wall; some can even be placed outdoors.
