Types of Water Heaters

Before the development of modern plumbing and water heaters, it took a huge amount of effort to heat water for washing. The water had to be pumped by hand, then heated over a fire in large tubs. Today, though, we can enjoy plenty of hot water by simply turning a tap.

Types of Water Heaters

Our team at Metro Plumbing has extensive experience working on water heaters, and we are familiar with all the major models. In this article, we’ll go over a few of the most popular types of water heaters to help you determine which is best for your needs.

  • Storage Tank Water Heaters – As the name suggests, storage tank water heaters have a large reservoir to store heated water in until it is needed. The tanks in these water heaters can hold anywhere from 30 to 80 gallons of water, which is more than enough for most households’ needs. However, keeping that amount of water hot at all times requires a great deal of energy, so the associated heating bill will be significant.
  • Tankless Water Heaters – In contrast, tankless water heaters do not have reservoirs of hot water ready to go. Instead, they heat the water only when you request it—this type of heater uses hot coils wrapped around the pipes to heat the water in seconds. A tankless heater uses less energy than a storage tank heater, but the flow rate is somewhat reduced.
  • Heat Pump Water Heater – Heat pump water heaters are a third popular model, and unlike the other two examples, they do not generate any heat. Instead, heat pumps draw heat energy from the environment, then transfer the heat into the water to warm it up.
