The Pros and Cons of Tankless Water Heaters


Tankless water heaters, also known as on-demand water heaters, have become popular among homeowners. They are more energy efficient, take up less space, and can provide hot water on demand. But are they a better option for your home? In this blog post, we will discuss the pros and cons of tankless water heaters so you can make an informed decision.


a. Energy Efficiency: One of the main advantages of tankless water heaters is that they are more energy efficient than conventional tank water heaters. Tankless water heaters heat water on demand, which means they only use energy when hot water is needed. This can result in energy savings of up to 30% on your monthly utility bills.

b. Space Saving: Tankless water heaters take up less space than traditional water heaters. They can be mounted on a wall, giving you more room in your basement or utility closet.

c. Durability: Tankless water heaters can last up to 20 years, which is longer than the lifespan of a traditional water heater. They are also easier to maintain, which means more savings in the long run.


a. Higher Upfront Costs: Tankless water heaters are more expensive upfront than traditional water heaters. The installation costs can be 2-3 times more, requiring a professional plumber.

b. Limited Hot Water Output: Tankless water heaters can only output a certain amount of hot water at a time. If you have a large family or numerous bathrooms, you may need to install multiple tankless water heaters to meet your hot water demands.

c. Temperature Control: Tankless water heaters require precise temperature control. If the incoming water temperature is too low, the unit may be unable to heat the water to your desired temperature.


a. Hybrid Water Heaters: If you want to take advantage of the energy savings of a tankless water heater but still want the convenience of a tank water heater, a hybrid water heater may be a good option for you. Hybrid water heaters combine the benefits of both tankless and traditional water heaters to provide an energy-efficient and high-output water heating solution.
