Water Heater: Tank VS Tankless

Posted on December 9, 2020 by Bailey Horlander

There are two basic styles available, tank water heaters or tankless water heaters. Heartland Quality Heating and Cooling installs both tanked and tankless. Both use a heat source to take cold fresh water and heat it to approximately 120 degrees Fahrenheit. How the two types do this are completely different. The tanked style has basically been the same technology for centuries, whereas the new tankless have only been around for the past 20 years. There are advantages and disadvantages of both so let’s look at the pros and cons.

Tank Style – Natural Gas

Tank Water Heater

The tanked style water heater has been around for a very long time. The design has undergone several changes for basic safety and energy efficiency but the principles are the same.  It takes fresh cold water into the bottom of a tank and heats the water to the desired temperature. This process has limited hot water reserve so if you use a lot of hot water you will run out. This water heater is designed to last trouble free for 10-12 years. The biggest positive about this style water heater is no electricity is needed for it to operate.

Tankless Style – Natural Gas

The tankless water heater has been around for over 20 years and is starting to become more widely used due to what it offers. This type qualifies for energy rebates with most gas utility companies. Tankless still take fresh cold water and heat it to a desired temperature but it doesn’t have a reservoir tank, it heats the water instantly. The biggest advantage of the tankless is it never runs out of hot water (provided it has been sized correctly). There are other advantages too:  the unit takes up less room than a tanked unit, it’s much more energy efficient, and is designed to last 20-25 years. The negatives of going tankless are upfront costs and that electricity is needed for the unit to work.

These pros and cons depend on the application of the new water heater and expectations you have for the amount of water you typically use. If you have any additional questions or are interested in upgrading your water heater, please give us a call or text us
