What Is a Tankless Water Heater?

A tankless water heater, or an on-demand water heater, heats water for your house on demand, rather than storing heated water in a tank waiting to be used. This system can deliver a near-unlimited hot water supply and take up significantly less space than a traditional water heater. A tankless water heater is an excellent option if you have a small home and need extra space or a large family that requires a lot of hot water. 

Benefits of a tankless water heater can include:

  • Endless hot water
  • Up to a 0.98 Uniform Energy Factor (UEF), which means 98 percent of the energy goes towards the intended purpose of heating water.
  • 24 to 34 percent more energy efficient than conventional storage tank heaters when using less than 41 gallons of hot water daily.
  • Don’t require standby energy. Great for vacation or second homes, which only need hot water periodically, versus standard tank heaters, which consume energy even when on standby.
  • A 20+ year life expectancy is longer than the traditional tank heater’s expected 10 to 15 years.
  • Components can be replaced individually, whereas tank heaters require entire replacement.

Tankless water heaters typically provide around two to five gallons of hot water per minute. Gas-powered heaters are generally more efficient and produce higher flow rates than electric ones, but models for both are available.

Tankless water systems must be sized correctly to supply enough water for simultaneous, multiple uses in large households. For example, simultaneously running a dishwasher, shower, and washing machine may push a tankless water heater to its limit. Consider installing multiple tankless water heaters to overcome this flow limit for larger homes.

On-demand water heaters cost more initially than traditional water tanks, but they have significant advantages over conventional water heaters in the right circumstances.

Tankless Water Heater Installation & Replacement

There are a lot of considerations and options when it comes to replacing and installing new water heaters, and for the best results, it is crucial to get it done right.

Improper installation can lead to costly problems or repairs down the road.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
