Top reasons for choosing a tankless water heater

January 28, 2016 4:48 pm

There are several factors to consider when replacing your water heater – cost, size, efficiency, demand and longevity are all important. Are you tired of running out of hot water when you’re in the shower? Or perhaps you’re looking for more energy-efficient ways to consume hot water in your home? A tankless water heating system may be the perfect solution for you as it offers many advantages over conventional water heaters.

Reduce Your Water Heating Costs

One of the big bonuses of tankless water heaters is the energy efficiency they offer. Tankless water heaters use natural or propane gas to heat water on demand. Using an electronic ignition system instead of a pilot light, the unit commences the heating process when it initially detects water flow, and once the demand for water ends, the unit shuts down. No energy is used once the water stops flowing through the system’s heat exchanger. A tankless water heater has no hot water storage, and therefore offers no chance for thermal heat loss, meaning possible energy savings of up to 40 percent.

In contrast, when you consider traditional water heaters, anywhere from 20 to 40 percent of the energy they consume is wasted through heat loss from the storage tank.

Endless Hot Water

Tankless water heaters work by heating up water instantly, on demand. They can run all day long if you need them to, and they will always supply you with hot water for all your needs whether that’s bathing, cooking, washing dishes or doing laundry.

Conventional water heaters, however, are notorious for running out of hot water, sometimes when you need it most, and then taking a long time to heat the water back up again.

Significant Space Savings

The compact design of a tankless water heater affords you almost limitless installation options. About the size of a carry-on suitcase, they can be installed on virtually any wall inside your home, most common is in a utility or laundry room. The average space savings compared to a 40 gallon conventional water heater is 12-16 square feet.


Tankless water heaters typically have a lifespan of 20 years or more in residential applications. Compare that with the 10-15 year life span of a conventional hot water heater, and you will see that the tankless system offers much better long-term value.
