5 Pros and Cons of Tankless Water Heaters

5 Pros and Cons of Tankless Water HeatersAre you tired of running out of hot water in the middle of a shower? If so, you might want to consider installing a tankless water heater in your home. However, before making the switch, it’s important to understand the pros and cons of tankless water heaters. Here are five of each:


1. Energy efficiency: 

Tankless water heaters only heat water when it’s needed, which means they use less energy than traditional water heaters that constantly heat and store water.

2. Space-saving: 

Tankless water heaters are much smaller than traditional water heaters, which can save valuable space in your home.

3. Long lifespan: 

Tankless water heaters typically last longer than traditional water heaters, with a lifespan of up to 20 years.

4. Endless hot water: 

With a tankless water heater, you’ll never run out of hot water since it heats water on demand.

5. Lower utility bills: 

Since tankless water heaters use less energy, they can result in lower monthly utility bills.


1. Upfront cost: 

Tankless water heaters are more expensive to purchase and install than traditional water heaters.

2. High installation costs: 

Tankless water heaters require a professional installation, which can be costly.

3. Limited hot water output: 

Although tankless water heaters provide endless hot water, they may not be able to provide enough hot water for multiple tasks happening at the same time.

4. Maintenance requirements: 

Tankless water heaters require regular maintenance, such as flushing the system, to prevent mineral build-up and maintain efficiency.

5. Inconsistent water temperatures: 

Since tankless water heaters heat water on demand, the water temperature may fluctuate if multiple hot water sources are being used at the same time.

Tankless water heaters have many benefits, such as energy efficiency and space-saving, but they also come with some drawbacks, such as high upfront costs and maintenance requirements. It’s important to weigh the pros and cons and consider your specific needs before making the switch to a tankless water heater.
