Traditional vs. Tankless Water Heaters

Traditional vs. tankless — which water heater is right for you? If your water heater is old, rusty, not producing hot water, makes unusual, persistent noises, or leaks—it’s time for a replacement. But, what to replace your current system with? How do you know which water heater—traditional or tankless—is best for you and your family’s water usage? That’s where we here at Parzival Plumbing comes in. We are here to breakdown the pros and cons of each water heating system, so you can make an informed decision when purchasing your new unit. Here is everything you need to know about finding a water heater that aligns with your lifestyle.

Traditional Water Heater

A traditional water heater controls the temperature of your water by constantly heating it within a storage tank. Most traditional water heaters hold between 40 and 120 gallons. Ask a professional about what factors should be taken into account before purchasing a unit, your nightly bath may depend on it.


-The installation cost of a traditional water heater is less than that of a tankless water heater. On average, your new traditional unit will cost you between $500 and $1,000.

-They are easy, and inexpensive, to replace.


-Your water bill for a traditional water heater will likely be higher than your monthly costs would be for a tankless unit. Why? Because your tank will constantly refill and reheat regardless of whether your water is actually being used.

-You can run out of hot water. Once you have used all of the water in your tank, it needs to refill and reheat a new batch before it can provide warm water for your next shower.

-Traditional units take up more space. Depending on how large your house is will determine how large of a tank you will need.

-It has a shorter life span than its counterpart. Traditional water heaters only last between 10 and 15 years.

Tankless Water Heater

Rather than storing water in a tank, a tankless water heater uses gas or electricity to warm your water when you want it! Generally powered by gas or electricity, they only heat water at the time it is being used.


-Tankless water heaters will cost you less to operate than traditional units. As this system only heats water when you are actively using it, you will see an energy savings of up to 25%!

-You will never have to worry about running out of hot water. With a tankless water heater, you will always have warm water when you want it!

-This water heater does not require a ton of space because it does not have a tank!

-Tankless water heaters have double the lifespan of traditional water heaters.


-Tankless vs. traditional water heater price – a new tankless water heater holds a price tag between $2,000 & $4,500.

-If you currently have a traditional unit, and you want to switch to a tankless one, the cost to convert your system over to a tankless network will require the relocation of existing piping, which is not easy, or cheap, feat.

-Tankless units are not great multitaskers. If you are using multiple showers at the same time or doing laundry while trying to run a bath, this system can fail to keep up with your hot water demand.
