How Do Tankless Water Heaters Work?

Water heaters are one of our most useful household appliances. They readily supply hot water with a turn of a faucet, making cleaning and showers infinitely easier. Water heater owners in Orem must decide between traditional and tankless systems. Here is an overview of how tankless water heaters work.

Tankless, or “on demand,” water heaters connect to your plumbing in the same way as a traditional heater. Unlike a traditional heater, however, they heat water as needed instead of keeping a tank continuously hot. This results in more efficient heating and because there is no standby heat loss, energy consumption can be drastically reduced.

A heat exchanger is activated when you turn on your water. It uses electric or gas power to heat the water as it flows through on its path to your faucet. The heat exchanger heats water very rapidly, so there is no need to store a large tank of preheated water. Since there is no tank, a tankless water heater can be installed in relatively tight spaces, including small utility closets, on walls, and beneath cabinets.

Tankless Waterheaters | OremThere are two types of tankless water heaters: point-of-use and whole-house. Point-of-use heaters only provide hot water to a couple outlets, while whole-house heaters are used for all outlets. Because of their smaller size, point-of-use heaters are often installed very close to their outlets in order to maximize their efficiency. They are most commonly electrically powered. Whole-house heaters are larger and require more space; they are generally fueled by propane or natural gas.

Tankless heaters require less fuel than their traditional counterparts, which can save users a significant amount of money on heating bills. They can, however, require more water usage than traditional models. Tankless heaters supply unlimited amounts of hot water almost instantaneously, and often last many years longer than heaters with tanks.
