On Demand Water Heaters: What to Know Before You Upgrade

Posted by Paul Wadsworth on Wed, Dec 23, 2015 @ 08:00 AM

Tankless or on-demand water heaters deliver hot water to your home as it's needed. The fact that they aren't constantly heating and storing large amounts of water that you may or may not need can help reduce your home's energy costs.

How On Demand Systems Work

A tankless water heater doesn't need a large storage tank to hold heated water. Instead, when you turn your hot faucet on somewhere in your home, pipes deliver cold water into a small unit. Gas or electric heating is then used to heat the water to the set temperature; then the system delivers the heated water to the faucet.

The Advantages and Disadvantages

Energy savings are an advantage; however, unlike a conventional water heater, the flow rate may be affected due to the fact that the water is being delivered and then heated. You can improve flow by using a gas heated model. You also can install more than one tankless system to ensure that the smaller tank can keep up with a larger home's demands. This can be convenient if you have a large group of adults living in your home, or if you have higher than normal hot water use.

We have already pointed out that energy savings are the major advantage when it comes to replacing a conventional system with a tankless or on-demand system. For homes that don't use a lot of hot water, you may find that energy savings are anywhere from around 24% to 34%. Homes with greater usage will find that the savings are under the 10% mark.

Another positive when it comes to this type of system is that they usually have a longer lifespan--if properly maintained. The lifespan of a tankless system can be upwards of 20 years, compared to 10 to 15 years on a conventional model. Parts that are easily replaced can increase the system's life span.
