The need for warm water becomes very necessary during the winter season. You won’t feel the excitement to take that cold shower or even do that dishwashing.

In this kind of critical situation, a heating system will be your light at the end of the tunnel. But the main challenge comes when you have to choose the perfect one for your home. As technologies are upgrading, so does the innovation of different water heaters.

Following the article, you will get all the information about the tank and tankless water heater. This will act as a guideline and an instruction manual that you can easily use during the time you are ready to buy the best heating system.

Tank Based Water Heaters

Tank Based Water Heaters

This heater comes with a storage tank with a limited water supply. The waters are heated continuously for 24 hours, and you will be able to use it any time without any hassle.

As the waters are staying warmer due to this heating system, a huge amount of energy will be consumed, and due to that, your electricity bill might gradually rise with time.

Installation Cost

The installation cost will vary for different homes because all of them won’t have the same requirement.

Some might require a larger heater with different specifications or vice versa. As a result, the cost starts at a minimum of $952 and can go up to $2098.

Preferable Installation Location

You don’t have to go through any kind of trouble while doing the installation process. It might take a couple of hours to get the job done, and then you can enjoy the incoming hot water.

The best location for it to install is kitchen closets or even garages. You won’t be able to put it in an outdoor area because it will get damaged by the change in weather.

Types and Lifespan

There are three types of heaters, electric, propane, and natural gas. Propane and natural gas models are energy-efficient, and for the electric one, some amount of energy will be consumed. If you can maintain it properly, you will be able to use it for more than a decade.

Storage Limit

The tanks can store around a minimum of 20 gallons and a maximum of 80 gallons of hot water depending on the size. Due to the tank, you will need to create some extra space inside your home so that it can be properly fitted.


  • Smooth and flexible installation process
  • Highly effective in case of an emergency as there will be already stored hot water.
  • No additional charges will be necessary inside the home when the electric heater will be installed.


  • Additional energy consumption due to continuously heating of water.
  • Chances of leakage in the tank.
  • Small lifespan

Tankless Water Heaters

Tankless Water Heaters

This heater is an updated version of the tank based one. You will get hot water on demand, and there will be no energy consumption.

The reason is due to the heating element inside the heater as it heats the incoming water only the time you turn on the faucet. You will be able to save some money out of your electricity bill as well.

Installation Cost

The cost will also be dependent on the type of quality and size you are going to pick for your home. You have to spend an extra amount of money in the case of this heater, and it will be within the range of $2044 to $5898.

You might be surprised by looking at the cost, and it is absolutely natural. But keep in mind about the fact that your electricity bills are getting decreased with time and some amount of money is getting saved along the process. So, it is a good investment.

Preferable Installation Location

The size of this heating system is smaller than the tank based one, so you don’t have to be tensed about the space. It can simply be installed at any location of your preference. Both indoor and outdoor installations are compatible with this heater.

The installation might be crucial because of various reasons. If you use the electric one, you have to modify the electrical system for your home, and for the gas unit, there must be a new gas supply line. In addition to that, you might need to install a new exhaust ventilation system or some new pipes (if needed).

Types and Lifespan

The types are the same as the previous heater. With good maintenance, you can easily use it for around two decades or more than that.

Operation Process

There will either be an electric or a gas coil in order to heat the water. When you turn on the faucet, the coil will get heated up, and then it will transfer its energy onto the water.

If you use your entire home appliance that uses water at the same time, the water flow rate will decrease, unfortunately. For larger homes, more than one heaters are best to install (to be on the safer side).


  • Highly efficient
  • Huge lifespan
  • No additional space needed
  • A decrease in electricity bills


  • High installation cost
  • Modification of gas or electrical systems are needed

Which One Should You Go for?

If you have a moderate budget and you don’t prefer to upgrade the electric or gas units of your home, then you should definitely buy the tankless water heater. Make sure you are leaving enough space for its proper placement.

A tankless water heater is preferred for the kind of people who needs hot water instantly and is also looking for ways to make the environment greener. The water will only be heated when you will need it.

Otherwise, it will stay normal. Also, the energy-saving will be a huge benefit for you and the society because no additional greenhouse gases will get released into the atmosphere. Finally, you will need only a small amount of space for its adjustment.
