The Pros and Cons of Tankless Water Heaters: Is It the Right Choice for You?

In the realm of water heaters, tankless options have been making a splash in recent years. Unlike traditional tank-style heaters, which store and continuously heat water, tankless heaters provide hot water on demand. They come with their own set of advantages and disadvantages. If you’re considering making the switch, let’s explore the pros and cons of tankless water heaters to help you decide if they’re the right fit for your home.

Pros of Tankless Water Heaters:

  1. Energy Efficiency: Tankless heaters are highly energy-efficient. They only heat water when you need it, eliminating the standby heat loss that occurs in traditional tank-style heaters. This efficiency can lead to lower energy bills.
  2. Endless Hot Water: Say goodbye to running out of hot water during long showers. Tankless heaters provide a continuous supply of hot water, making them ideal for larger families or homes with high hot water demands.
  3. Space-Saving: Tankless units are compact and wall-mounted, freeing up valuable floor space compared to bulky tank-style heaters. This can be a game-changer for homes with limited space. Futhermore, these tanks can be installed anywhere. They can even be relocated from the existing location and put outside.
  4. Longer Lifespan: Tankless heaters typically have a longer lifespan than traditional heaters. With proper maintenance, they can last up to 20 years, which is considerably longer than the 10-15-year lifespan of tank-style units.
  5. Reduced Risk of Leaks: Since tankless heaters don’t store water, there’s a lower risk of leaks or water damage compared to traditional tanks that can corrode and crack over time.

Cons of Tankless Water Heaters:

  1. Higher Upfront Cost: Tankless heaters tend to have a higher initial cost than traditional units. This can be a significant drawback for budget-conscious homeowners.
  2. Limited Flow Rate: The flow rate of a tankless unit can be limited. If you have multiple hot water demands simultaneously we can easily run a high GPM unit or we can install dual units for larger homes.
  3. Installation Complexity: Installing a tankless heater can be more complex and may require changes to your home’s gas or electrical systems. This can add to the overall installation cost.
  4. Cold Water Sandwich: Some tankless systems experience a phenomenon known as a “cold water sandwich.” This occurs when there’s a brief burst of cold water between hot water usage, which can be inconvenient.
  5. Maintenance Required: Tankless heaters need regular maintenance, including descaling to prevent mineral buildup. Neglecting maintenance can lead to reduced efficiency and potentially costly repairs.

Are There Benefits From SoCal Gas?

Yes! There is a benefit for those eligible for rebates from SoCal gas. In addition, they  have an option for built-in recirculation pumps.
If you would like almost instant hot water throughout the home set up on a timer, that is an option.
The better units we install have stainless steel heat exchangers.
Best units are Rinnai, Navien and Noritz

What Else?

A tankless water heater necessitates a larger gas line than a traditional water heater, needs electricity, and calls for special venting. Consequently, the typical cost for transitioning from your current tank water heater to a tankless model starts at around $3,700.00 depending on setup parts and labor, unit not included. Please note that this price may fluctuate depending on your unique circumstances. Conversely, the usual cost for replacing a standard 50-gallon water heater stands at $1600.00.


Tankless heaters offer numerous advantages, including energy efficiency, endless hot water, and a longer lifespan. However, they come with a higher upfront cost and potential installation challenges. It’s crucial to weigh these pros and cons against your specific needs and budget when deciding whether to go tankless. If energy savings, space-saving, and never-ending hot water are high on your priority list, a tankless water heater might be the perfect fit for your home.
