The Pros and Cons of Tankless Water Heaters


If you’re considering upgrading your water heater, you may wonder whether a tankless water heater is the right choice. While there are certainly some benefits to going tankless, there are also some drawbacks that you should be aware of.


1. Energy Efficiency: One of the biggest advantages of tankless water heaters is their energy efficiency. Unlike traditional tank heaters, which constantly heat and reheat water even when you’re not using it, tankless heaters only heat water as needed. This can result in significant energy savings over time.

2. Space Savings: Tankless water heaters are much smaller than traditional tank heaters, which can be a significant advantage if you’re short on space. They can be mounted on a wall, freeing up floor space and making them a great option for smaller homes or apartments.

3. Longer Lifespan: Tankless water heaters typically last longer than traditional tank heaters, with an average lifespan of 20 years or more. This can be a big advantage if you’re looking for a long-term investment in your home.


1. Higher Upfront Cost: While tankless water heaters can save you money in the long run, they do tend to have a higher upfront cost than traditional tank heaters. This can be a barrier for some homeowners, especially on a tight budget.

2. Limited Output: Tankless water heaters can only produce a certain amount of hot water at a time, which can be a disadvantage if you have a large family or frequently use hot water for multiple tasks at once.

3. Maintenance Requirements: Tankless water heaters require regular maintenance to keep them running efficiently, which can be a disadvantage for some homeowners who want to avoid dealing with ongoing maintenance tasks.
