7 Reasons to Get a Tankless Water Heater Installed

Tankless water heaters have been growing in popularity lately, and for a good reason. These little compact boxes provide a luxurious amount of warm water, ensuring you don’t run out in the middle of your shower. They have completely wiped out the giant, ugly-looking water heater tanks at homes.

But how so? Simple: remarkable engineering. A tankless water heater is innovative, modern, and much more efficient. The wait was worth it; the enormous and complex machines are gone for good. Millions of families globally have now switched to tankless water heaters.

If you’re still stuck with one of those huge tanks and are thinking about making the switch, then these seven reasons to get a tankless water heater might be for you.

Tankless Water Heater

1. You'll Get Instant and Unlimited Hot Water

Unlike tank-based water heaters, tankless water heaters only heat water when required, on- demand. It means they start heating the water as you open the faucet of a tap or shower. The heat exchanger unit in the heater warms any water passing through it. In about 15-30 seconds, you get water in usable condition. You no longer have to wait forever to get hot water as with a tank- based system.

This on-demand style of operation also allows the unlimited supply of hot water. You could shower the whole day, yet the warm water won’t cease. Traditional tank systems have a limited supply of hot water as per the capacity; that’s why a supply shortage scenario is not uncommon.

2. They're Far More Energy Efficient and Eco Friendly

Tankless water heaters are modern for a reason. They’re energy-efficient and save you money in the long run. The on-demand and real-time heating nature save energy.

Tank-style water heaters have a capacity of about 50 gallons and consume electricity round the clock to maintain the water temperature. However, since tankless water heaters have no storage, they don’t need to maintain water temperature.

As per the U.S. Department of Energy, tankless water heaters can save anywhere up to 8-50% more energy than tank-based heaters. And, as it always goes, the lesser the water you consume, the more you’ll save. For example, a 40-50 gallon of water usage is 25-35% more energy efficient.

Tankless water heaters use technology to reduce carbon emissions, hence keep indoor air pollution in check. Indoor air pollution is harmful to both the environment and you and is a rising concern among households.

They are also manufactured with replaceable and recyclable parts to reduce waste in the landfill, negatively impacting the environment. Tankless systems don’t add to our trash, save water, and are cost-effective; what more could you ask for?

3. They Have a Lower Risk of Leaks and Water Damage

The most significant risk with tank-based water heaters is running into water leaks and damages. Since they store gallons of water, there’s a chance of mineral build-up from hard water at the bottom of the tank. The minerals cause corrosion, lead to leaks and eventually damage the tank.

Tankless-based tanks don’t have to deal with these issues since there’s no tank. However, they aren’t immune to all kinds of leaks or damages. The tank-less nature makes it less prone to such issues.

4. You'll Need Less Maintenance

The key to a happy life is less irksome tasks. The fact is, maintenance is annoying. Tank water heaters need to be periodically cleaned, often due to mineral build-up, silt, or slime. They need to be drained, scrubbed out, and flushed. The process isn’t always easy because there’s half a ton gallon of hot water sitting and staring at you.

A tankless water heater makes life easy. They would still need maintenance but not as much as a tank-based system.

5. They Look Better and Save Space

You might have figured it out by now that a tankless unit will save space. But, how much exactly? A tank-based heater can take up to 20 cubic feet of space. On the other hand, Tankless heaters are much smaller and can save up to 12 cubic feet of space. You could install other appliances in this space or keep it simply for yourself.

Moreover, tankless systems are sleek and chic. They will make your bathroom way more attractive.

6. You can Perform Several Tasks Simultaneously

Sometimes you’ll need hot water for more than one thing. A tankless water heater makes it very much possible to run several hot water appliances simultaneously. Want to run the dishwasher, washing machine, and shower at the same time? Your new tankless heater has got your back. The endless supply of hot water makes it possible.

However, a tankless heater has a flow rate. Breach the limit, and it might not work. They can heat only a certain amount of water at any given time. If you want to run 6-7 appliances, the water heater most likely will give up. Therefore, it is imperative to keep the flow rate in mind while performing simultaneous tasks.

7. They Last Longer

Tankless water heaters are much more durable than tank-style heaters. They are generally manufactured with higher quality materials that are both durable and reliable. The on-demand nature adds to the extended life since they only run when required, while a tank-based system has to function round the clock to maintain water temperature.

On average, a tankless heater lasts for 15-20 years, and a tank water heater lasts anywhere between 10-12 years. This can be cost-saving in the long haul.

Customer Reviews

Called Absolute for my 81 year old landlord in the height of Summer heat. Scott came out to inspect the old beast of an AC and found many issues. He took the time to educate us, note everything, photograph it and provide several recommendations...and my stubborn landlord has done nothing LOL. A couple months later we asked that Scott come back out and he was there that same day.

I contacted Absolute Airflow to check my mother's AC, as it was not getting cold. The tech (Scott) arrived earlier than his scheduled time, and was very knowledgeable, professional, and most of very personable with my mother in letting her know that the issue was. Superb customer service Scott and thank you Absolute Airflow! I highly recommend Absolute Airflow.
