Tankless vs. Conventional Water Heaters: What’s Better?

February 21, 2020

How do you know what kind of water heater is best for your home? When it comes to choosing between conventional and tankless models, it’s important to understand the differences in order to determine what is the best for your particular circumstance.


Conventional Water Heaters

A conventional hot water tank.Conventional water heaters are called hot water tanks, and there are two main types – natural gas, and electric. Hot water tanks heat and store hot water until you need it. When you run the hot water, at say a shower or bathtub, that stored hot water gets used up. The hot water tank then fills up with cold water, which gets heated again for the next time it is needed, and so on.

Hot water tanks come in various sizes ranging from 12-80 Gallons, the most common size being 40 US Gallons. The tank size you need will depend on how many people share your household and how much hot water you use on average. A plumber can help you determine which size of tank is best for your needs.



Tankless Water Heaters

Tankless heaters are more expensive to buy and install than conventional hot water heaters; however, they last longer, and are much more energy efficient, which can save money in the long run.

Tankless models can last 20+ years, whereas the typical lifespan of a hot water tank tends to be between 10-15 years, making tankless water heaters a good choice if you are planning to stay in your current home for the long term. They are also very compact, and hang on the wall, making them perfect for townhomes, or any house that could benefit from freeing up floor space in the mechanical room.
