Tankless water heater systems are growing in popularity. Many homeowners, much like yourself, are doing their research. These tankless systems, also known as on-demand or instantaneous water heaters, provide hot water only when you need it most. There is no energy loss like with a storage tank water heater, meaning you’ll save money. When you activate a faucet, you expect hot water quickly. And you’ll get it – a tankless model delivers.

How It Works

A tankless hot water heater allows direct access to hot water without the use of a bulky storage tank. When you turn on the tap, cold water moves directly through the pipe into the tankless unit. Then, either a gas burner or electric element heats the cold water. The result is a constant supply of hot water sent through the pipes of your home. You never have to wait for the supply to restock, because a tankless model does not use a storage tank. However, the output limits the flow rate.

Generally, a tankless water heater offers a rate of 2–5 gallons per minute. Sometimes, a large unit is not enough to supply hot water to the entire house. This is especially the case when you have multiple hot water sources working at once, such as a shower, washing machine, or dishwasher.

Advantages of a Tankless Water Heater

If your home uses 41 gallons or less of hot water per day, then a tankless water heater will save you 24–34% per month. It is more energy-efficient overall. For a home that uses over 86 gallons per day, you’ll save around 8–14% per month. These percentages directly translate to monthly savings for your home.

Other key benefits include:

  • Fewer operating costs, thanks to being more energy-efficient
  • Better for the environment
  • Extended lifespan when compared to a storage water heater
  • Increased property values, if you ever choose to sell your home
  • Less space required
  • Reduced risk of water damage

Cons of Tankless Water Heaters

Of course, you’re a consumer. You need to look at both the pros and cons of tankless hot water heaters. The pros sound wonderful, right? However, look at the cons as well to make a more informed decision:

  • The initial installation is often expensive
  • Models with electric controls fail to work during power outages
  • Limited supply of hot water available for multiple appliances
  • Slight delays in hot water flow

Is a Tankless Water Heater Right for You?

Well, now you’ve had an opportunity to look at both the benefits and drawbacks of a tankless hot water heater system. You’re able to make a more informed purchase. A tankless model is a potentially wonderful investment, but it’s not the right option for every homeowner.

If you have the money to invest in a tankless model, then absolutely, go ahead and install a tankless water heater. But if not, then consider waiting for a time. However, know that the energy efficiency will save you money in the long-run.
