Infrared Tankless Water Heater: What Is It and Should You Buy One

Tankless, or on-demand, water heaters hit the market a few years ago as an energy efficient alternative to the traditional gas heated water tanks. These systems heat up water as needed rather than storing it in a tank. Energy.gov notes, “They don’t produce the standby energy losses associated with storage water heaters, which can save you money.” Plus they save a ton of space since there’s no massive storage vessel for lava hot water.

Sounds like a good deal, right? Well, before you jump on the bandwagon, let’s take a closer look at how on-demand water heaters work, how much money they could save you, and if they’re really worth the money.

How Do On-Demand Water Heaters Work?

It’s pretty simple; water comes into your home and is heated via elements inside the system. Then it winds through the pipes to the faucet or appliance of choice.

Most tankless systems have the capacity to provide two to five gallons of warm water per minute. Energy.gov says, “For homes that use 41 gallons or less of hot water daily, on-demand water heaters can be 24%–34% more energy efficient than conventional water heaters.” They add that families can expect to save up to $100 on their energy bill each year by installing a tankless water heater.

Which Tankless Water Heater Is Right for My Home?

If you decide to purchase an on-demand water heater, you’ll need to think about a few things when you research which one is right for your home:

  • Take a look at your past water bills to see how much water you use on average. Most systems will tell you the capacity they can handle.
  • Identify whether you want it to be gas or electric.
  • Learn at what temperature the water is coming into your home.
  • Decide how warm you want your water to be when you want to use it.
  • Old coil elements electric tankless water heater vs Infrared Quartz Elements electric tankless water heater

Mother Earth News notes that if the difference between the water coming into your home and the water you want to use is 45 degrees, it’ll take a large on-demand system to raise the water temperature. Either you’ll have to re-evaluate your needs, or consider purchasing an extra tankless system to support the first.

Is an On-Demand Water Heater Worth the Investment?

On-demand systems can help you reduce energy costs, save space in your home, and offer warm water when you need it. If you love saving money and making energy-efficient upgrades to your home, looking into a tankless system may be right up your alley.

Last thing, I promise. Before you run out and buy your on-demand water heater, have you considered any potential drawbacks? Well, if you haven’t, Consumer Reports sure has. Here’s a short list of problems they found with tankless water heaters:

  • Many people reported inconsistent water temperature.
  • The initial purchase price is high.
  • This type of water heater needs constant maintenance.
  • If it does break, it costs more to fix.

These drawbacks only happen in metallic elements electric tankless, vs infrared electric tankless , you don't see any corrosion, and no maintenance plus more flow rate and temperature rise. The Infrared electric tankless could last more than 15 years, on other hand the competitors electric tankless last only couple of years and require constant maintenance.

However, since my water heater is brand new, I’m not running out to purchase a tankless water heater tomorrow. So, if you just bought a new water heater, stick with it for a while, and start putting money aside for an on-demand water heater in the future when you start to see the bill goes up or you would prefer no maintenance and buy one for your folks ! :)
