Tankless Water Heater

Tankless Water Heaters: Why We Are Obsessed

A tankless water heater is exactly what you think it is, a water heater minus the storage tank. Traditional 30 to 50 gallon water heaters consistently waste energy keeping your water hot, just for it to sit there until used. While tankless water heaters (also called on-demand water heaters) produce hot water only when you turn on the faucet, start a cycle on the washing machine, switch on the dishwasher, or otherwise call for hot water. Imagine getting the same amount of hot water (or more) from a water heater the size of a carry-on suitcase—while also saving on your utility bill! If your family still has to schedule shower times around the hot water supply, it may be time to consider making the switch to an instantaneous hot water heater.

How a Tankless Water Heater Works

  1. When the need for hot water arises by turning on a shower, washing machine, dishwasher or faucet, cold water flows into the on-demand water heater from the inlet pipe found at the bottom of the unit.
  2. A flame is ignited and heats the two heat exchangers (devices that transfers heat from one source to another.)
  3. Water is preheated as it passes through a stainless steel heat exchanger, capturing any extra heat (or latent heat) before it escapes into the vent system.
  4. Water continues to be heated as it passes through the heat exchanger, and exits from the hot water outlet pipe to travel through the pipes of the home to the water fixture where hot water is needed.
  5. The tankless water heater will adjust flame output as needed to ensure the temperature set point is maintained.
  6. As the hot water fixture shuts off, cold water stops flowing into the tankless water heater and the flame extinguishes. The tankless water heater is now off until the next time hot water is needed!

Why We Love ‘Em

Life Span

The average lifespan of a normal storage tank water heater is around 8 to 12 years compared to tankless heaters which can last up to 20 years! Opting for a longer-lasting tankless model can save a homeowner from needing a replacement every 10 years.


On-demand water heaters can be mounted on a wall saving you ground and storage space. They are also much more compact than bulky storage water heaters.

Money Saving

Although the initial installation costs may startle you, their month-to-month costs are much lower than a normal water heater. As a homeowner, you can expect to save hundreds annually on gas or electric due to the efficiency of a tankless water heater. Because tankless water heaters last so long, the upfront cost will pay for itself when your water heater lasts twice the average span.

Hot Water On Demand

With a storage tank water heater, households have a limited supply of hot water, AKA as much as the tank holds. For families of 4 or 5, it can become frustrating when you’re forced to take a cold shower after everyone else. Tankless water heaters ensure hot water immediately thanks to high-powered gas burners or electric coils that warms the water right when you need it.

Whether a tankless water heater is right for your home, is for you to decide. With almost every purchase, there are pros and cons so pick the water heater that best fits your water usage, lifestyle situation, and budget. A tankless water heater is a great choice for large families and/or those who are looking to save money in the long run.
