The Latest in Tankless Water Heating Technology

Schedule Now

Tankless water heating technology outperforms conventional water heaters in many ways. First and foremost: no tank! The familiar storage tank has always been a weak link in water heating performance and efficiency. Water stored on “standby” cools and requires re-heating—a substantial energy drain. Also, because tank capacity is limited, so is the amount of hot water available at any given time.

A tankless system heats water on-demand only, utilizing no storage tank. In addition, the unit delivers hot water continuously as long as demand continues, so there’s no interruption while you wait for another tank to heat.

New tankless water heating systems are more adaptable and efficient than ever. Here are some of the newest tankless water heater technologies, features, and improvements incorporated in the latest units.

Simpler Installation

Cold and hot water piping in most existing homes is typically configured for a storage tank heater, which sometimes complicates the installation of tankless heaters.

New tankless models now feature water input and output connections on the top of the unit, duplicating fittings’ position and spacing on a storage tank heater. This makes direct replacement faster and more straightforward.

In addition, more new tankless units are engineered for use with 1/2-inch gas lines, which are the typical standard in residential construction.

Instant Hot Water

We’ve all been there, waiting for hot water by running cold water. Waiting for water to get hot wastes both water and time.

One of the newest on-demand water heater technologies is the recirculating pump. At least one major manufacturer of new tankless systems now incorporates a recirculating pump that continuously circulates freshly heated water into the supply line to the fixture while diverting cooled water back to the main water pipe. The result is instant hot water with no lag time when you open a faucet.

There are now even models that will predict how much hot water will be needed and will schedule water heating based on that schedule. This smart recirculation will ensure that energy is not wasted by running during off-times when hot water isn’t typically used.

Because the hot water is instantly available at your tap, you no longer need to waste water waiting for the hot water to arrive at your faucet.

The typical lifespan of a traditional tank water heater is 10 to 15 years. A study from the Department of Energy shows that a tankless unit can easily last 20 years. Additionally, tankless water heaters can extend their service life beyond 20 years by replacing a few key components.

More Affordable

Tankless water heaters have come down in price, and traditional tank water heaters have increased in price (primarily due to increased material costs). You can get a non-condensing tankless water heater for as low as $700 (not installed), which is around what a traditional water heater will run.

Condensing vs. Non-Condensing Tankless Water Heaters

Like traditional water heaters, many tankless water heaters use natural gas as the fuel source to heat the water. This method produces by-products like carbon monoxide and other gases. A non-condensing tankless water heater (and traditional ones) vents these gases out of your house.

A condensing unit captures these exhaust gases using condensation. The gases are then recycled into an additional heat exchanger and burned again to produce even more hot water. Tankless water heaters were already very efficient, but adding a second heat exchanger and capturing exhaust gases for a second round of heating increases the efficiency even further!

Lower Maintenance

One problem tankless water heaters had in the past was that maintenance was a little difficult. For optimum performance and efficiency, tankless heaters require annual maintenance to remove mineral deposits, known as “scale,” that accumulate in the heat exchanger. Isolation valves in new units now expedite maintenance and make descaling more effective.

"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."
