What Are Tankless Water Heaters?

Before understanding “what is a condensing tankless water heater,” it would be a good idea to polish the basics. Let us learn more about tankless water heaters and how they work.

Ever since mankind has begun using water heaters, tanks for storage have been a must when it comes to the device. However, the recent technological revolution has led to several changes in the water heating industry. 

Modern tankless water heaters do not store water and heat it continuously like tank-based ones. Instead, tankless heaters use heating technology that will instantly warm up your water on demand. These devices serve a dual purpose as they reduce wasteful practices and gradually lower your energy bills.

How Tankless Water Heaters Work

These heaters possess a heating element that warms up the water as it passes through the machine when you need it. Most tankless heating devices use either gas or electricity to perform this job. 

So, when you turn on the faucet, cold water enters the machine. It triggers the heating element, which turns it into hot water and sends it through the faucet. You can usually control the temperature of the water by adjusting both hot and cold water faucets.

Understanding Condensing Tankless Water Heaters

Condensing tankless water heaters take the energy-saver game one step up from regular tankless heaters. These heaters use a heating element and also a condensing element. The condenser in these heaters turns the exhaust gas into water vapor that exits through the drain. This speeds up the process while reducing your power usage.

A warm bath with no pauses is every man’s dream after a long day. So, once you get one of these heaters, forget about waiting for the water tank to refill mid-shower.

Energy Efficiency

While heaters without a condensing element do not utilize the exhaust gas, these do. So, these heaters work fast by ensuring the total usage of all factors and redirecting them toward heating your water. a

Faster heating results in running the device for shorter periods and lesser energy consumption. This benefit provides much aid to your wallet.

Easy Installation

Another perk of using these heaters is their compact and lightweight nature. They are great space-savers and also easy to install. You need not deal with any technical hassle while putting up a tankless water heater in your home.

Better Durability

Buying a water heater is a long-term investment. So, users would seek something that would last. Since condensing tankless heaters use a lighter mechanism than tank-based ones, they run more smoothly. This feature plays a role in extending the device’s lifespan.

Minimal Carbon Footprint

While the heater’s efficiency helps you save time and money, it also guards the environment. The exhaust gas redirected towards the water will not escape into nature and directly affect our ecosystem. These heaters minimize the release of greenhouse gasses and leave behind minimal carbon footprints.
