Going Back to School With Tankless Water Heaters 101

A Guide to Tankless Water Heaters

When households want to reduce their energy bills, save space, and have hot water when needed (eliminating waiting for the water tank to heat up between showers), tankless water heaters can be their home’s best water heating solution. This guide will share what tankless water heaters are, how they work, and the benefits of installing them in homes.

What Is a Tankless Water Heater?

While traditional storage water heaters have a large tank to provide hot water to a household, with tankless hot water heaters, the water is heated as it passes through the system and only as needed.

Because they only heat water when needed instead of continuously heating a large tank of water, tankless water heaters can be more energy efficient than traditional storage water heaters. Additionally, their heating water on demand and the lack of a storage tank allow tankless water heaters to not run out of hot water like storage water heaters do when the hot water in the tank runs out.

How Does a Tankless Water Heater Work?

  • When a faucet or showerhead is turned on and hot water is requested, cold water enters the tankless water heater through an inlet pipe.
  • Inside the unit, the heat exchanger quickly heats the incoming cold water as it flows through.
  • The tankless water heater uses a flow sensor to detect the water flow rate and a temperature sensor to measure the incoming water temperature. Based on these readings, the heater adjusts the heating elements or gas burner to achieve the desired hot water temperature.
  • Since these systems heat water as it flows through the unit, they can provide a continuous supply of hot water to the household. There is no need to wait for a storage tank to refill and reheat the water.

Advantages of Tankless Water Heaters

While most households are familiar with storage water heater units, tankless water heaters provide many benefits to families. Some of their benefits include:

  • Energy efficiency: They are more energy-efficient than traditional storage tank water heaters by only heating water when needed and not keeping a large water tank hot.
  • Savings on utility bills: The efficiency of tankless water heaters is reflected in lower water heating costs for homeowners.
  • Space-saving: These systems are compact and can be mounted on walls, allowing homeowners to save space.
  • Longer lifespan: These systems generally have a longer lifespan than traditional storage water heaters. With proper maintenance, they can last around 20 years or more, and storage tank water heaters typically last about 10-15 years.
  • Endless hot water: Since they provide hot water on demand, there is no risk of running out of hot water, even with multiple simultaneous hot water demands in different parts of the house.
