Pros of Condensing Tankless Water Heater

If you’re considering switching to a tankless water heater, it’s probably for reasons like unlimited hot water capacity, low maintenance, and a lower utility bill.

But did you know there are two types of tankless water heater systems – condensing and non-condensing? Condescending water heaters recycle heat from the exhaust gas to help warm the water, making this type of unit more energy-efficient and, potentially, a better long-term investment for your home.

How condensing water heaters work

Condensing water heaters address wasteful, open systems by using the exhaust gas to further heat water instead of releasing all that warm hot air. Adding a condensing system consists of having a second heat exchanger that loops exhaust back through the system before releasing it.

The gasses that pass within the system aren’t usually very hot. However, as the gas makes its way through the second heat exchanger, some heat is transferred to incoming cold water. At that point, the water through the primary heat exchanger. There, it achieves the right temperature using far less energy. The upside is that already-produced heat is recycled back into your water supply, resulting in a lower water bill.

The pros of a condensing water heater

As explained above, condensing water heaters pull heat from the exhaust, increasing energy efficiency. Most condensing tankless water heater systems have an efficiency rate of about 90 percent, making them a cost-effective must-have for your home.

While condensing modes are generally more expensive than their non-condensing counterparts, they are more likely to produce more long-term utility savings.

So, if you are a first-time homeowner with a considerable budget, a condensing water heater is a great investment to make.

Is a condensing tankless water heater right for you?

Any tankless water heater will offer benefits over traditional tank units. But if you want to get the most out of your tankless water heater, you should seriously consider a condensing system.
