Tankless Water Heaters


Tankless Water Heaters: Benefits and Different Types


What Is A Tankless Water Heater?

Primarily due to the green movement, tankless water heaters have gained popularity worldwide and most recently in the United States. A tankless water heater, also known as an instantaneous water heater, is a compact wall unit that takes up less space than a standard water heater. When you turn on the hot water at the sink, for instance, cold water will travel through a pipe and into the tankless water heater, where it will then warm up either a gas or electric element that will produce your hot water.

    A residential tankless water heater is an energy-efficient, environmentally friendly way to provide hot water for residential heating needs. There are various types of residential tankless water heaters on the market today. Some of these include gas, electric, and solar residential tankless water heaters. North Peachtree Plumbing offers a variety of residential tankless water heaters that will fit your needs!


    We recommend a tankless water heater if you need a new water heater. Tankless water heaters are small, energy-efficient systems that heat water only when it is needed. When you turn off the faucet, the heater also switches off, so there is no heat loss in the standby mode.

    Tankless water heaters are slightly more expensive upfront, but they are designed to save you energy and money over time.


    “Demand (or tankless) water heaters can be 24 percent to 34 percent more energy efficient than typical storage tank water heaters for residences that consume 41 gallons or less of hot water daily,” according to Energy.gov. Tankless water heaters (if gas-fired) can save homeowners over $100 per year if they are used for a long time. According to the US Department of Energy, electric tankless water heaters still save homeowners $44 per year.


    A gas-fired tankless heater can save you over 60% on energy costs compared to a traditional 50-gallon electric heater. Anyone wishing to replace their present water heater should consider these models.


    Gas Tankless Water Heater Pros:

    • energy efficient
    • affordable
    • instant hot water
    • longer lifespan

    Electric Tankless Water Heater Pros:

    • can be added at anytime
    • high efficiency
    • long-term savings
    • environmentally friendly


    What are the Differences Between “Traditional” Tank Storage Water Heaters and the Tankless Heaters?


    Tankless water heaters are very energy efficient, and they save you money in the long term. They allow you to have instant hot water at any time, and they are reliable. Tankless water heaters have a longer lifespan than your average water heater. Due to the longer lifespan, you won’t have to worry about replacing or updating your water heater for quite some time. Tankless water heaters are more efficient than your average water heater. Because they are more efficient, they will produce warm water more efficiently, and you won’t have to worry about waiting forever for the water to heat up. Tankless water heaters are more affordable than your average water heater. Getting it installed is an easy process and won’t cost a ton of money to do so. This means that when it eventually has to be replaced, it won’t cost a lot of money for you in the future either. Tankless water heaters are environmentally friendly. So, while you’re getting warm water, you’re also taking care of the planet.


    The majority of residences have storage tank water heaters. An insulated tank, which generally holds 30-50 gallons of water, is used to heat and store the water until it is needed. A pipe emerges from the top to transport hot water to its intended location, such as the kitchen, bathroom, or other sinks.


    Tankless water heaters, also known as on-demand water heaters, use high-powered burners to quickly heat water as it passes through a heat exchanger and provide it to your faucets or shower without the need for a tank. Electricity or gas are commonly used to power tankless water heaters. In Consumer Reports tests, these sorts of water heaters were 22 percent more energy efficient on average than gas-fired storage-tank models.

    The main difference between traditional and tankless water heaters is that the former has a storage tank that collects hot water while using appliances such as dishwashers or washing machines. With “tankless” versions, you get an endless hot water supply since they don’t store it in any tanks.


    Drawbacks of Storage (Tank) Water Heaters

    • Utility bills are a little higher.
    • Storage tank water heaters raise your utility bills since they heat and then reheat the water to a pre-set temperature, regardless of your hot water needs. If these water heaters are used in a cool setting (location), they will work harder during the winter months, increasing your gas or electric expenditures.
    • They take up more space than on-demand water heaters due to their size.
    • If you have a small home, you may have trouble finding adequate space for storage tank water heaters. In addition, unlike tankless water heaters, they cannot be installed outside the home.
    • You don’t want to be the last one to shower in the family.
    • If you frequently take several showers and have a standard household water heater, you may wish to upgrade to a larger one. While this approach may alleviate hot water scarcity, your energy expenditures may rise in tandem with the availability of hot water. Three showers in a row are the maximum capacity of most storage tank water heaters. Unless you favor frigid, not hot, showers, you won’t enjoy being the fourth shower-taker.
    • Tanked water heaters need to be replaced more frequently than tankless water heaters.
    • Because storage tank water heaters have a shorter usable life (approximately 12 years compared to on-demand water heaters), you may need to buy and install them nearly twice as often as tankless water heaters, diminishing your purchase savings.

    Is It Worth It To Buy a Tankless Water Heater?

    The short answer is yes, it is worth investing in a tankless water heater. You’ll save a lot of money over time, and over time, it will pay for itself. This is an excellent choice for those looking to make their home more energy-efficient and those who want to better care of the environment.

    Tankless water heaters also provide endless hot water, which allows you never to run out and always have access to it whenever you need it without waiting or worrying about an upcoming shutoff. You won’t have to worry about the noise either since they make nearly as much noise as traditional tank units. This is an excellent quality to avoid unwanted noise in your home. This unit only heats the water on-demand, so there’s no wasted energy heating up water that isn’t needed or doesn’t remain in the tank at all times.

    A tankless water heater has a longer lifespan than your average water heater. This makes it an excellent investment because you know at the time of purchase that it is not something you will have to replace in a few years. Tankless water heaters are reliable. Tankless water heaters are also much smaller than your average water heater. This means it won’t be taking up much space either.

    A tankless water heater is also better for the environment. Tankless water heaters produce fewer carbon emissions than your average water heater. They only operate when there is a demand for hot water. They are energy-efficient and environmentally friendly. A tankless water heater can be hooked up to your home’s central heating system. This means you can take advantage of the entire house heating system through one unit, making it cheaper to run multiple appliances simultaneously because you are only using one energy source instead of several.

    On-demand (tankless) water heaters save between 24 and 34 percent more energy than storage tank water heaters for homes that use less than 41 gallons of hot water per day. If you use a lot of hot water daily (about 86 gallons), you could save an extra 8 to 14 percent on your energy bill.

    A tankless water heater will cost you a little more than a traditional storage tank water heater. Still, tankless models last longer than conventional water heater models, resulting in a 20+-year useful life, as opposed to storage tank types, which only last 10 to 15 years before self-destructing, potentially flooding your basement or home, depending on their location. Install a tankless water heater at each hot water outlet if you want to “hit a home run.” Why? Installing on-demand water heaters at all hot water outlets in your home could save you between 27 and 50 percent on energy costs.

    Great work at a fair price. Tom replaced all our toilets with low flow ones and we could not be any happier. He cleaned up the areas and left no mess like other plumbers we have used.

    — Cliff Roswell, Ga

    Called with a leaking water heater. These guys came out the same day got it replaced and hauled off the old heater. I called around and this company was the best priced and have great reviews. Will use it again.

    — David Johns Creek, Ga

    We love Tom! He's the best! He is always available, on time, and has been able to do things other plumbers told me were not possible. I have referred him to friends and family and they love him, too. I wouldn't use anyone else for our plumbing needs.
