Should you get a tankless water heater?

Tankless water heaters are becoming increasingly popular. They don’t take up a lot of space. They don’t even store water. When you are in the market for a new water heater, consider all your options. Here are the pros and cons of tankless water heaters.


The biggest advantage of a tankless water heater is the amount of energy you will be saving. Upfront, you will be spending a lot of money to get the tankless water heater installed. In the long run, it will save you even more money. The hot water is provided to you on demand. This means that you won’t have water sitting in a tank just waiting to be used. It can be costly paying for the water to constantly be heated.

The average water heater will last up to 13 years. Tankless water heaters are estimated to last nearly double the amount of time. If you plan on staying in the same home for a long time, you will save money on replacing it.

Tankless water heaters take up less space than traditional ones. Traditional water heaters can hold up to 75 gallons of water. They are typically two feet in diameter and five feet tall. This can take up a significant amount of space in your garage. A tankless water heater is less than two feet wide and only two feet tall. You can use the extra space to store more things in your garage.


The pros make it sound like a no brainer to get a tankless water heater. It is important to be fully aware of the facts before making a purchase. Tankless water heaters are not perfect.

They have limited output. Traditional water heaters store up to 75 gallons of water. This is plenty for showers, laundry and other needs for a short time. Hot water can run out and it may be an hour before you have hot water again. The water is constantly kept hot in the tank so no matter when you use it, the water will still be hot. A tankless water heater can only supply a few gallons of hot water at a time. If people are taking showers, doing laundry and dishes all at the same time, not everyone will have the luxury of hot water, sized properly though you will never run out of hot water!

Even though tankless water heaters will save you money in the long run, you can be dropping a large amount initially. Some people don’t have that much money to spend upfront. Traditional water tanks can be as cheap as $400.

Traditional water heaters will only use 50,000 BTU of gas or propane while it’s heating the water. Because tankless water heaters will heat up the water on demand, it uses up to 200,000 BTU of gas or propane. Many houses require gas piping modifications.
