All you need to know about Tankless Water Heaters

By Katie Clarke – Marketing Associate

Invented in 1970, Tankless Water Heaters deliver endless on-demand hot water. With both gas and electric models available to suit your home or business, Tankless Water Heaters are an option for all types of consumers. Tankless Water Heaters function by instantly heating water as it passes by a heated element, which is triggered the minute your hot water tap is turned on. This is in contrast to tank-type hot water heaters that hold a large drum of water, heating the entire drum to provide hot water for your home or business.

Sizing is rated by the maximum temperature rise at that given flow rate. Keep in mind, if you choose a size that’s too small, you risk overloading your Tankless Water Heater.

Benefits of a Tankless Water Heater

Tankless Water Heaters have multiple benefits, and we’ve compiled a shortlist highlighting the most important!


Tankless Water Heaters are much smaller than the alternate Tank-Type Water Heater, taking up less space in your home because they heat your water without a large storage tank.


Tankless Water Heaters only heat water on an as-needed basis, making them 40% MORE energy efficient! For these same reasons, they reduce any water waste as well.

Longer lifespan

Tankless Water Heaters last almost twice as long as its competitor; this means up to 20 years if properly maintained.
