Should You Install a Tankless Water Heater?
Posted: Feb 23, 2021
Tankless water heaters are becoming increasingly popular because of their numerous benefits. However, there are some drawbacks with these units compared to their storage tank counterparts.
Here's a look at some reasons why you should consider installing a tankless water heater and some reasons why it's best to stay with a more traditional unit.
Pros of Tankless Water Heaters
There are numerous benefits to install a tankless water heater, as these units exist with convenience and long-term cost savings in mind.
First and foremost, tankless water heaters can save you money on your energy bills. That's because you don't have to heat a 40-gallon to 50-gallon tank of water, as the water warms as you need it.
Estimates suggest that a tankless heater can save you up to 50% on your energy consumption, although it depends on how much hot water you use in a day.
If your household uses less than 41 gallons of water per day, you can expect to save close to 35% on your energy consumption, while homes that use about 86 gallons per day would save between 8% and 14%.
You can save as much as 50% if you install tankless heaters near each outlet rather than using a centralized system for the entire property.
In real numbers, the average family saves about $100 per year with a tankless system.
Hot Water on Demand
Another outstanding benefit of a tankless water heater is that you don't have to worry about running out of hot water. This feature is excellent if you have a large family because the hot water tank tends to empty pretty quickly when multiple people take showers or do laundry.
Since tankless heaters operate on-demand, they create an endless supply of hot water, no matter how much occupants are using.
In theory, you could take a ten-hour-long shower and have just as much hot water available at the end of it as when you started.
Uses Less Space
Space is often a consideration when selecting a water heater. Large tanks take up a lot of room, and if you live in a smaller home, you can better use that space on other things.
A hot water storage tank is usually between 54 and 60 inches tall and has a diameter of about 20 inches. That's a lot of space to take up, but tankless heaters are much different.
These units are only about 18 inches wide and ten inches tall. They typically attach to a wall or sit in a basement or crawl space in an area you weren't using anyway.
Overall, these assemblies save space, making them considerations for homeowners who are short on it.
Low Risk of Damage
Tank-style water heaters aren't necessarily risky items to have in the home. However, when they leak, you could end up with water everywhere, doing all sorts of damage inside your home.
They can also run into issues because of sediment clogging the valve. While rare, a clogged valve could lead to a pressure build-up and an explosion, which you can avoid with a tankless unit.
No tank means there's nothing that can leak or explode, creating a safer water system in your home.
Finally, there's the longevity of tankless water heaters. While tank-style heaters have a life expectancy of between eight and 12 years, tankless heaters can last about 20 years and sometimes longer.
As a result, a tankless heater is a solid investment that you won't have to replace for a very long time.
Cons of Tankless Water Heaters
Of course, no product is perfect, and there are some cons associated with tankless water heaters that you should consider.
Higher Upfront Cost
First, you should note that a tankless water heater is more expensive than a traditional unit. It will also take some work to have it installed, and you'll want to go with a certified installer like the technicians at Hunt's Services to ensure it's done the right way.
It's worth noting that the longevity and energy savings often make up for the initial cost.
Take Longer to Deliver Hot Water
Next, you should be aware that tankless water heaters take a bit longer to deliver hot water than a tank. The reason is that the water isn't preheated, and it takes a few seconds for it to pass through the device and to the taps.
This issue isn't, but it will feel slightly different as you get used to your new setup.
No Hot Water Without Electricity
Tankless water heaters rely on electricity, so you won't have hot water when the power goes out. Even gas-powered heaters use electricity because they have a control panel that operates the system.
Therefore, a power outage means no hot water until the issue is repaired.
Is a Tankless Water Heater Worth It?
Before deciding if a tankless water heater is right for you, make sure you go over the pros and cons. These devices are incredibly convenient, efficient, and durable, making them popular items for homeowners.
At the same time, they're a little more expensive up front and take some getting used to after installation.
