Why choose a tankless water heater?
People are transitioning away from tank heaters for several reasons. Tankless heaters are a newer technology, greener, and less expensive. They also produce more hot water at a reduced cost.
Here’s why you should trade in your traditional tank boiler and switch to a tankless water heater.
Goodbye to noisy, bulky water tanks
Traditional “boiler” style heaters were not designed with efficiency in mind. They take up an inconvenient amount of space in your home, requiring considerable room in a basement or large cupboard. They’re also often scalding-hot to the touch, meaning they can be a danger to young children if not stored out of sight.
Bulky, noisy, and leaky? No thanks.
In addition to their size, old-school heaters don’t keep tabs on how much hot water you actually use; instead pre-filing their tanks with hot water, which then is depleted throughout the day. This causes three common issues:
First, if you run through the whole tank, you can be left without hot water while the system slowly refills.
Second, if you regularly use less hot water than the size of your heater tank, you’re continually paying to heat unneeded water.
And third, leaving warm water sitting inside an aging tank can be a recipe for potential leaks, flooding, and contamination by bacteria.
In summary, we don’t recommend tank heaters because…
- Many gas-fired tank heaters operate at half the efficiency of tankless heaters. Today’s best electric tankless heaters can deploy practically all of their energy towards heating water.
- Tank heaters are only able to provide consistent hot water when usage habits are predictable and stay within the limit of the tank. Adequately powered tankless heaters provide hot water as soon as you need it, for as long as you need it.
- Because they don’t store large amounts of water, tankless heaters won’t flood your basement or harbor dangerous bacteria.
Hello to efficient, modern heating
For most homes, tankless heaters beat out other water heating options when it comes to price, efficiency, and performance. Many of the units on this page are also near-silent, running at a similar volume to new kitchen appliances.
Here are the main benefits of owning a tankless water heater…
Thanks to their microprocessors, flow sensors, and conductive heating elements, tankless heaters can easily detect when hot water is needed and quickly convert energy into heat. This makes the vast majority of tankless heaters between 80% and 99% energy efficient.
Lower utility bills
According to the leading appliance certification board, Energy Star, the average household can save thousands of dollars over the lifespan of a tankless heater in comparison to a tank unit. While tankless heaters draw more energy when heating water, they heat on-demand, meaning they spend far less time in an active state.
Tankless heaters have an estimated lifespan of 20 years, which again is up to double that of traditional boilers. Beyond base lifespan, tankless heaters also require less maintenance on average. Instead of an annual service, tankless units simply need flushing to remove a buildup of hard water minerals—even this is unnecessary if you filter your water using a good quality water softener.
Endless hot water
When a tankless heater is correctly sized for a home’s needs (e.g. adequate flow rate and power capacity) it will provide hot water for as long as you need it. The best tankless heaters can even handle multiple appliances running at the same time without a perceptible drop inflow.
The storage tank of a traditional heater may be up to 60 gallons, which is a considerable size and takes up a large amount of floor space in an average home. The average size of a tankless heater is 28 x 20 x 10 inches, which means that they can be mounted to walls, hidden in cupboards, or even kept outside.
