Tankless Water Heater Pros and Cons

There are pros and cons to anything we buy, especially in plumbing technology. Tankless water heaters are not an exception. The technology with tankless water heaters is getting better every year, so more people are starting to investing in this newer technology.

Pros for Tankless Water Heaters

Water Heater Size

The size of the unit is very small, so they are easy to place in any home or business situation.

Low Energy Consumption

They help you conserve water and energy. The hot water is “on-demand” so to speak. With a traditional water heater, you always have water being heated waiting to be used. Tankless heaters heat the water when you need it.

Constant Temperature

Since the tankless water heaters heat on demand, you never run out of hot water.

Cons for Tankless Water Heaters

High Maintenance

Since the technology is still advancing, the maintenance on these tankless heaters can be more frequent than a traditional heater.

Expensive Upfront Cost

The upfront cost of a tankless hot water heater is much more than a traditional water heater.

Expensive to Maintain

With more maintenance comes more maintenance costs.


Mineral deposits can affect them, causing them to sometimes become temperamental. This causes them, again, to be more high maintenance.
