Definition of a tankless water heater
A tankless water heater is an energy-efficient and cost-saving type of water heating system. Unlike traditional, tanked water heaters, these units do not use tanks, but rather heat cold water directly when it is needed. They are usually powered by natural gas or electricity, but propane and fuel oil can also be used in some cases.
Tankless water heaters save energy by only heating a small amount of water at one time and providing that source of hot water when needed. Depending on their location in the house, they may also provide increased safety features due to avoiding potential danger associated with traditional tanked systems.
Installation costs tend to be higher than those of traditional tanked models, however the lifespan of a tankless heater is much longer than that of a tanked system allowing you to recoup more ways in household maintenance over its lifetime.

A tankless water heater has a number of advantages compared to traditional storage-tank systems. These units are far more efficient since they don’t continuously sustain heat like a tanked system, and as a result, they can save homeowners between 25%-50% in energy costs annually.
These systems also generate hot water on an as-needed basis and provide an endless supply of hot water, meaning no more cold showers! Furthermore, since these water heaters don’t require the large claw-foot tanks of the past, they are considerably smaller and can often be mounted to the wall to save space in your utility room or closet. Tankless systems also require less maintenance than traditional storage-tank models. However, many cities still have codes requiring annual maintenance for safety reasons.
Finally, some manufacturers offer models with remote control capabilities that allow you to activate your system from afar via a smartphone app or other device for added convenience.

Types of tankless water heaters
Tankless water heaters come in two distinct types – Gas and Electric.
Gas Tankless Water Heaters: These types of heaters use natural gas to produce heat and can be vented directly out the side of your home. They are typically more efficient than electric tankless water heaters and are also able to provide a higher volume of hot water. They may require more installation work than their electric counterparts, however.
Electric Tankless Water Heaters: Electric-powered tankless water heaters are becoming increasingly popular, due to their small size and relatively easy installation process. They use electricity to generate heat, which is then transferred into the water inside the heating chamber. While they can take longer to bring hot water to taps or showerheads than a gas-powered unit, they tend to be more energy efficient due to the lack of exhaust emissions associated with gas appliances.
Electric tankless water heaters
Electric tankless water heaters are the most popular choice among homeowners because of their compact size, ease of installation and low maintenance requirement. They are wall-mounted units that use a small electric element to heat water as it passes through the unit. Because they don’t require fuel storage tanks or permanent ductwork, electric tankless water heaters can be installed almost anywhere in the home.
They are energy-efficient since they only produce hot water when you need it, so you don’t have to worry about heating water unnecessarily or wasting energy by running an empty tank. Electric tankless models typically cost less than natural gas or propane models, but may require a higher initial investment because of their higher installation costs and special wiring requirements.
Gas tankless water heaters
Gas (natural gas or propane) tankless water heaters are a popular choice if you have access to cheap natural gas and propane. Gas water heaters provide more energy efficiency as compared to electric ones costing you less over time to heat your water. This type of tankless model offers fast hot water delivery, even when it is heavily used and runs at a low cost.
Gas tankless water heaters work differently than other types of tankless models. They have a built-in venting system that provides fresh air to the combustion chamber, allowing them to draw in the outside air that is needed for optimal combustion. The pilot light then ignites in order to begin heating the water inside of the tankless model as it passes through. This type of heating system typically works best when there isn’t an outside window or wall blocking off direct access from the combustion chamber.
Although these high-efficiency models come with higher upfront costs, they offer significant energy savings over time and provide hot water on demand for any occasion – whether it’s for a large shower or just one cup of tea! Boosting performance even further, certain gas tankless models are equipped with additional features such as recirculation pumps that reduce lag time significantly between use intervals, making sure that you get hot water at all times in your home!
Factors to consider when buying a tankless water heater
When you’re looking for the best tankless water heater for your home, there are several factors you should consider. Knowing your specific needs and understanding the options available on the market is key to finding the best value for your home. Here are some of the most important elements you should keep in mind when researching and buying a tankless water heater:
- Size: Tankless water heaters come in a variety of sizes. Depending on the size of your family and the amount of hot water you need, choose a heater with enough power to satisfy your needs without overpaying. The more power it requires, the larger it will be and vice versa.
- Fuel Type: Tankless water heaters come in electric, gas or hybrid models depending on your specific needs. Electric models are cheaper but require more energy to operate than gas-powered models. Gas-powered models tend to provide hotter water than electric since they can be adjusted easily, but they require ductwork installation which can be costly. Hybrid models are more energy efficient by combining stored hot water with an on-demand system that only heats up when needed.
- Flow Rate: The flow rate indicates how much hot water can be delivered at once from your system; this will depend on its capacity and power output as well as other factors such as local climate conditions or altitude levels for gas-powered systems. Make sure to check if this figure is going to meet your household’s hot-water needs before committing to a particular model.
- Installation & Maintenance: Most gas-powered tanks require professional installation since they must comply with local building codes; electric tanks are usually easier to install by yourself though unqualified persons should refrain from doing so due to safety reasons as well as manufacturers’ warranties requirements. In either case, sometimes special parts or tools might be necessary so beginners should seek professional help whenever in doubt about their capabilities or qualifications . Maintenance costs should also be taken into consideration before buying either type of tankless unit since some repairs may require specialized tools or experts visits.
Size and capacity
When shopping for a tankless water heater, one of the first things to take into consideration is size and capacity. Tankless water heaters are available in a variety of sizes, from small units that are installed under the sink, to larger units that can be mounted on a wall.
- Smaller units typically range from about 1 to 3 gallons and can easily provide enough hot water for an individual or limited family unit.
- Larger tankless water heaters are best suited for larger families or businesses with higher hot water needs. These types of systems can run up to 8 gallons per minute and provide hot water on demand.
- Depending on your usage, you may also want to consider investing in a unit with multiple outputs so that you can use it in different locations at once.
Flow rate
Flow rate is one of the most important features to consider when selecting a tankless water heater. The flow rate is the measure of how much hot water is available on demand and in a minute. A higher flow rate is essential when you have multiple fixtures, like multiple showers and other appliances, running at the same time. Many are measured in gallons-per-minute (GPM).
Some tankless water heater offers up to 10 GPM depending on their model, which can support usage for an entire family. However, it may be necessary to purchase more than one heater if your use demands a higher GPM rating. Regardless of how many tankless heaters you purchase, each has a potential flow rate; hence it’s important you choose your model carefully. This information can be found in product manuals or through manufacturers’ websites.
Conclusion
In conclusion, purchasing a tankless water heater can be a daunting task. There are many aspects that need to be taken into consideration when deciding which model is best for you and your home. Factors such as ambient temperature, incoming water temperature, capacity needs, fuel type preference and budget should all be taken into consideration during the selection process.
However, we are confident that after researching the various models of tankless water heaters available in 2021-2022 and taking the factors stated above into account, you will have no trouble finding the best one for your home.
