Tank Versus Tankless Water Heaters: What You Need to Know

August 14, 2020

Water heaters with storage tanks are vastly more common than their tankless rivals. But tankless water heaters are becoming more popular. With a tankless water heater, a unit the size of carry-on luggage will replace the large tank in your utility room. As a result, you can save space and up to $100 annually on utility bills in Hagerstown, MD. Read on to learn the differences between tank and tankless water heaters.


The clever design of a tankless water heater results in 30% more efficient operation than a tank water heater. However, tankless units come at a higher price. They can be double, if not triple, the upfront cost compared to conventional water heaters.

To maintain efficiency, consider regular maintenance with a plumbing membership. Our skilled team will catch early problems with award-winning service.


Tankless water heaters don’t only cost more to purchase. You’ll also pay more for the installation. A conventional unit is simply hooked up to a house, while a tankless unit requires us to make modifications.

A traditional water heater generally costs around $500 to install. Tankless water heater installation can cost double that or more.


You can consider the tank in a conventional water heater to be the limit on its output. But units without tanks promise hot water without limit. One complication lies in a relatively low flow from a tankless water heater. If you try to take a hot shower while the dishwasher runs, it may not suffice to keep pace.

Tankless water heaters are more efficient and limitless in terms of the hot water they pump out. Conventional water heaters are less expensive to purchase and install, but once they run out of hot water, you have to wait to get more.

Whichever water heater you choose, call Hagerstown Heating & Cooling today to find out about our plumbing services. We can walk you through the process of water heater installation and provide upfront estimates.
