It is becoming more and more popular to use tankless water heaters instead of traditional hot water heaters, like storage tank heaters, for hot water heating. There is a difference between a traditional hot water heater, which contains and stores the water, and a tankless hot water heater, which, as its name suggests, is able to produce hot water on demand without storing it beforehand.

The tankless water heater, also known as a demand-type water heater or an instantaneous water heater, is a type of water heater that provides hot water on demand when it is needed. There is no standby energy loss associated with these units, which means that there can be a large cost savings compared to storage water heaters. This article will provide you with an overview of how tankless water heaters work, whether one might be the right choice for your house, and what criteria you should consider when selecting the right one for you.

Here’s how a tankless water heater works

A tankless water heater is a type of water heating system that does not use a traditional storage tank. Instead, it heats water on demand as you need it. This means that you can have an endless supply of hot water whenever you need it, without having to wait for a tank to fill up.

Tankless water heaters are very efficient because they only heat water when you need it. This eliminates the need to keep a large tank of hot water heated and ready at all times, which can save you money on your energy bills.

Tankless water heaters come in both electric and gas models. Gas models are more expensive to purchase, but they tend to be more efficient and cost-effective in the long run. Electric models are less expensive up front, but they may not be as efficient and may cost more to operate over time.

Tankless water heaters can provide an endless supply of hot water, which can save you money on your energy bills. If you are considering installing a tankless water heater, it is important to compare the different models available and choose the one that best suits your needs.

To help you understand better how a tankless water heater works, here is a list of steps:

STEP 1 – Turn on the hot water tap

The first step is to turn on the hot water in order to ensure that hot water is flowing through your pipes. In today’s society, that explanation is not always straightforward. Make sure that you turn the knob towards the hot water if you have a single knob. Dual knobs make this process much simpler. Once you have located the hot water knob, turn it in order to allow the hot water to flow.

STEP 2 – The heater receives water

In other words, what should you expect now that the hot water has been turned on? Regular water heaters send hot water through the pipes from the tank to the faucet. As opposed to a tank-style water heater, a tankless water heater uses sensors that trigger an internal computer to begin heating the water when it is cold.

STEP 3 – Detection of water flow by a flow sensor

As soon as the internal computer detects that the machine has been triggered, it immediately calculates the right temperature for the burners to operate at. Gas burners or electrical elements can be used for this. No matter which way you choose, it makes hot water available continuously without the need to wait for a tank to refill.

STEP 4 – Burner is ignited automatically by the computer

What happens to all that hot water when you have a tankless water heater? As the flame heats up the water, it passes through a heat exchanger to reach its designated temperature. As soon as the tankless water heater is turned off, the water begins its journey through your pipes.

STEP 5 – A heat exchanger circulates water

An endless stream of hot water is available whenever you need it with a tankless water heater. The tankless water heater automatically shuts down when there is no longer a need for hot water. The result is constant and fresh hot water along with energy savings.

Tankless water heater selection criteria

When selecting the right model of tankless water heater, it is important to consider a number of factors such as the size and capacity of the unit, your specific hot water needs, fuel type and availability, and installation costs.

Size and Capacities

Tankless water heaters come in a wide range of sizes and capacities, so it is important to choose one that will meet your hot water needs. If you have a large family or use a lot of hot water, you will need a larger unit. Gas-fired models are typically more powerful than electric models, so if you have natural gas available, it may be a good option for you.

Installation Cost

Installation costs can vary widely depending on the type and size of unit you select. Electric tankless water heaters are usually the easiest to install, while gas-fired models may require some ductwork or other modifications to your home.

Fuel Type and Availability

Fuel type and availability is another important consideration. If you live in an area where natural gas is not available, an electric model may be your only option. However, if you have access to propane or another fuel source, a gas-fired unit may be a better choice.

Initial Cost of the Unit

Finally, you’ll need to consider the initial cost of the unit as well as the ongoing operating costs. Gas-fired models tend to be more expensive to purchase than electric models, but they also typically have lower operating costs. Electric tankless water heaters have no venting requirements and generally cost less to operate.

Final Thoughts

Tankless water heaters are a great way to save money and space in your home. They can provide hot water on demand, and they’re very efficient. However, tankless water heaters do have some drawbacks. For one, they’re more expensive than traditional water heaters. They also require more maintenance, and they can be tricky to install. Overall, though, tankless water heaters are a great choice for many homeowners. Thanks for reading!
