Why is a tankless water heater a better option for you?

Tankless water heater is becoming more and more common these days. But before we talk about the water heaters available in the market, it is important to know why a tankless water heater is better than its counterpart.

Better utilization of resources

A tankless water heater heats the water only when you turn the faucet on. This way, it prevents the wastage of power by holding gallons of water and heating it. Traditional water heater stores a large amount of water and heats it. Most tankless water heaters today run on natural gas or propane and even on electricity, and heat as much water as is required.


Long term savings

Even though the traditional water heaters are cheaper and easier when it comes to installation, the tankless water is the better option when it comes to long-term savings. This is because you are only heating as much amount of water as is actually required, thus saving both water and electricity bills.


Perfect fit even when space is less

Tankless water heaters are better for you if you have a restricted amount of space. Whereas the traditional water tanks take up a large amount of space, the tankless water heaters do not require a lot of space.

No Need  To Worry About Running Out Of Hot Water When You Take A Shower

Unlike the traditional water heater which may get empty on continuous usage, since the tankless water heater heats the water when it is required, you will never run out of hot water. All you need to do is installing a water pipeline from water tanks to your tankless water heater.

A tankless water heater is in every way the best option for the modern home. It is better suited to the more compact and fast-paced lifestyle of modern times.

That being said, what all factors would you like to consider before buying a tankless water heater? Well, for that my friend, you have to continue reading the article.

What are the factors I have to consider before buying a tankless water heater for my house?

Now that we know why you should buy a water heater, let us look at some things that decide which is the best tankless water heater for your use.

Size

One of the first things to look at your tankless water heater is its size. The size of the water heater determines the maximum temperature rise possible at a given flow rate. It is important to find a water heater that can supply your desired flow rate at the required temperature.

To find out the flow rate that you might require, determine the maximum number of applications that you want to run and their individual flow rate. Then, add all the individual flow rates to get the net flow rate required.

You also need to find the temperature that water has to be heated to. For this, you should know the normal water temperature and the temperature you wish to have.

For example, commonly the water we get is at 50 to 60 Fahrenheit. The normal household requires the water to be around 120 Fahrenheit. The difference of the both will give you the temperature requirement of your house.

Depending on your personal preferences and requirements, you should be able to choose the best tankless water heater for your use. You can ask your plumber’s assistance in case of any doubts.


Energy requirement

Another important factor to look out for while deciding the most suitable tankless water heater for your household is the energy requirement of the tankless water heater. Today tankless water heaters are available that run on natural gas, propane as well as electricity. So, it is important to find the system that is most effective and efficient for your house.

You can check for the EF (Energy Factor) rating of the water heater to determine how efficient it is. Today, stricter federal standards have caused the water heaters to have better EF ratings. The closer the rating is to one, the more efficiently the water heater works. It also helps you reduce your utility bills.

Tips To Consider While Installing Your Tankless Water Heater

  • While choosing the location for your tankless water heater, it is important to choose a place that is sufficiently ventilated.
  • The most efficient place to install your tankless water heater is on an outside wall that has close proximity to the water and electricity or natural gas supply source. This will help increase the efficiency of your tankless water heater.

Now that you know what all to look for in your tankless water heater, let’s have a quick look on some of the best and most sought after tankless water heater available in the market.
