What Is a Tankless Water Heater?

Unlike traditional tank-type water heaters, tankless water heaters don’t store and heat water in a large tank. Instead, they rapidly heat water the moment you open a hot water tap, then stop when you close it. This on-demand approach means that you don’t waste energy maintaining a supply of hot water. It also means that you’ll always have a steady supply of hot water, making cold showers a thing of the past.

Advantages of tankless water heaters

Tankless water heaters are growing in popularity for a number of reasons:

  • Save energy – Tankless water heaters don’t waste energy heating and reheating a large tank of water constantly. They only use energy when you need hot water.
  • Unlimited hot water – A tank of hot water can be completely depleted if demand is high. With a tankless water heater, supply is not an issue – you’ll have hot water as long as you have water running to your home.
  • Smaller size – With no tank, these water heaters are more compact and can be tucked away into tighter spaces.
  • Long-lasting – Tankless water heaters typically last 20+ years.

Disadvantages of tankless water heaters

While tankless water heaters have many advantages, it’s important to consider their disadvantages:

  • Higher upfront cost – Tankless water heaters cost more to purchase and install than tank-type water heaters. If you’re converting from traditional to tankless, installation will be more expensive.
  • Potential issues with volume – Tankless water heaters don’t run out of hot water, but they might have trouble keeping up with a high hot water load. If multiple people and appliances are using hot water simultaneously, a tankless water heater’s flow rate might not be high enough to provide.

Tankless Water Heater FAQs


The main downside of a tankless water heater is the higher upfront cost. When switching from a traditional water heater, your home will most likely need to be modified, which will drive the cost of installation up. You may also experience insufficient hot water if your tankless unit is not sized correctly for your needs.


That depends on your needs. If you constantly find yourself without hot water due to high demand, the performance of a tankless model can far outweigh the higher upfront cost. Tankless water heaters also have long service lives, giving you plenty of time to make up for the upfront cost in energy savings.

How much does it cost to replace a hot water heater with a tankless?

If you are switching from a traditional water heater to a tankless model, the additional cost to convert is unique to each home’s circumstances. If you choose a gas tankless water heater, your contractor may need to add a gas line or reroute your existing one. For an electric tankless water heater, your electrical system may need to be upgraded.


Instead of tank size, tankless water heaters are “sized” based on flow rate. That means that you need to calculate the maximum volume of hot water that may be needed at one time in your house. Once you know that, you can choose a unit with a high enough flow rate to keep up with your needs.
