Tankless Water Heaters: What You Save When You Own One

Nov 26, 2021 | Tankless Water Heaters

Tank water heaters are practical in that they heat the water before delivering it to faucets and showers throughout the house. However, the new trend slowly gaining popularity is that of tankless water heaters! Also known as instantaneous or on-demand water heaters, they do the same job without needing a large container in your basement or house.

But just what are the other pros of a tankless water heater? Here are what you save when you own one:

Quicker Heating

Gas and electric tank water heaters need about 20 to 40 minutes to fully heat the water before use. But what if it runs out of water? Then you’ll have to fill it up first and wait for another 30 to 40 minutes. 

On the other hand, tankless water heaters use an exchanger that heats up the water quickly and efficiently!

Better Warranties

Conventional water heaters come with six-year warranties, while tankless water heaters are warrantied for over two times that duration: 15 years. This means any damage to your tank water heater after six years is not covered, and the item will not be replaced.

On the other hand, tankless water heaters have more than a 50 percent chance of being replaced if they malfunction.

Fewer Hassles

As mentioned prior, tank water heaters are prone to leaks and combustion if they overheat or are old. These problems, combined with a shorter warranty period, mean an additional burden for your entire household. 

The water heater has to be turned off, evaluated, and replaced. The leak has to be mopped up, and no hot water is available for days until the new one arrives, whether covered by the warranty or not. And even then, installing a new tank water heater takes two to three hours, tops! 

Conversely, tankless water heaters are easily replaced because they’re smaller, don’t need an entire basement for storage, and have a warranty that’s twice as long. You won’t have to spend anything if it still falls under the coverage period and it’s quickly installed! Just hook onto the shower rod and plug into the socket! 

More Space

Speaking of storage, another quality that tankless water heaters save is physical space! Tank water heaters are usually manufactured between 40- to 60-gallon capacities. Their huge size requires a large, secure, well-ventilated place like the basement or attic. 

Then there are tankless water heaters, which are the size of a brown envelope and as thick as a messenger bag, that can be hooked onto a shower rod and plugged into an outlet in your Shower! There is no need to dedicate a room or large space for storage!

Lower Costs

The most practical quality of tankless water heaters is their cost-efficiency. In terms of price, regular water heaters can cost upwards of $2,000! The tankless variety can go as low as over $200, or roughly ten percent!

Standard tank heaters store heat for power, so they constantly have to use energy to maintain a high temperature, meaning your electricity or gasoline expenditures will shoot up.

But tankless water heaters? They’re plugged directly into your water supply and electrical socket. Since they’re much smaller, they generate less power to provide hot water and save up to 50 percent in energy costs because they only heat water used!


We hope these qualities have convinced you to replace your regular water heater with a tankless one. Try one out to see the huge, positive difference it has on your time, living space, costs, and hassles yourself.
