Are Tankless Water Heaters Good?

There are many benefits to tankless water heaters. For starters, these types of water heaters can last more than 20 years; this is comparable to traditional units, which tend to have a lifespan between 8 and 12 years.

Tankless units are also known as space-saving water heaters, as they take up significantly less space than traditional units. With all these advantages combined, it’s easy to see why so many people choose these long-lasting water heaters for their homes. You can potentially see increased energy savings, among many other benefits.


This is the first generation of tankless unit. These units use a heat exchanger to heat your water on-demand, and reach an Efficiency Factor (EF) of .82-.85. This technology has been in use in Europe and Japan for decades and is well-proven. The advantage of this type of unit is in reliability in that they are established products with few manufacturing issues.


Condensing units are the second generation of tankless water heaters. After a primary heat exchanger, these units use a second heat exchanger, which reuses the heat from your exhaust to further heat the water. This results in an increased efficiency of 92-94%. The benefit of cooler exhaust is that these units can be vented using (inexpensive) PVC, while the drawbacks included a higher unit cost and, similar to non-condensing units, a lower efficiency for short water draws.

Condensing hybrid

Condensing hybrid units are the third generation of tankless water heaters and were pioneered in the United States. These heaters incorporate a small – between 1 liter and 2-gallon – holding tank. This small holding tank keeps a reservoir of hot water, eliminating lower efficiency for short draws, meaning these water heaters achieve a true EF of .92-.96. A recent study by the Gas Technology Institute measured real life efficiency of condensing hybrid tankless water heaters and found the units consistently operated at 94% efficiency with little to no degradation due to short draws.

Are Tankless Water Heaters Reliable?

Tankless units are sometimes called “on-demand” water heaters, as they only generate hot water precisely when you need it. These endless hot water heaters are especially useful for larger households or homes with a high demand for hot water.

In the end, tankless units are reliable since they will never run out of hot water — unlike traditional ones with a water tank. As a result, you don’t have to wait for a tank to refill hot water before you can shower, wash your dishes, or complete any other important tasks.

How Efficient Are Tankless Water Heater Units?

Tankless hot water heaters are more energy-efficient than traditional units because they heat water as it is used instead of heating and reheating water in a storage tank. These energy-efficient water heaters will also maintain their efficiency over time, unlike traditional units, which require a professional technician to regularly flush sediment out of the tank. When sediment builds up in a water heater tank, this can negatively affect the appliance’s performance and lead to several problems, such as decreased efficiency.

Types of Tankless Water Heater Units

Our experienced technicians are trained to install three types of tankless units:

Non-Condensing Tankless Water Heater: If you currently have a traditional tank water heater, switching to a non-condensing tankless water heater could be one of the best options. These units require the installation of stainless steel venting for exhaust. Or you can simply utilize your existing ventilation.

Condensing Tankless Water Heater: These units use two heat exchangers, which can help you reap incredible energy efficiency benefits. Additionally, venting for a condensing tankless water heater can be accomplished using PVC, which is a material known for its affordability.

Condensing Hybrid Tankless Water Heater: These third-generation, cost-saving water heaters have small holding tanks that function as reservoirs for water. You can expect condensing hybrid tankless water heaters to be highly efficient and vent via PVC pipes.
