What Is a Tankless Water Heater?
Are you unfamiliar with tankless systems? You’re not alone. Many homeowners are just learning about the advantages of tankless water heaters.
Traditional water heaters store and continuously heat a tank of water. On the other hand, tankless water heaters heat water only when you need it. This is why tankless water heaters are sometimes called “on-demand water heaters.”
When you turn on a hot water tap, cold water flows through the tankless unit’s heat exchanger, where it is heated in seconds. This newly-heated water then flows through your tap for use. Since tankless units heat water as needed, you will never run out of hot water.
Some tankless water heaters are powered by gas. Others are fully electric. Each one offers distinct advantages. Our expert technicians will help you choose the best option based on:
- Your home’s infrastructure
- Energy costs
- Water usage patterns

Who Should Consider a Tankless Water Heater?
Tankless water heaters are ideal for certain lifestyles and home layouts. This section helps you determine if your household will benefit.
Best Candidates for Tankless Systems
Tankless water heaters are a great option for:
- Smaller families or couples with moderate hot water use
- Homes with limited space
- Energy-conscious homeowners looking to lower monthly utility bills and reduce waste
- New constructions or remodels that can accommodate a tankless unit from the beginning
Situations Where a Traditional System Might Be Better
Tankless water heaters may not be ideal for homes on well systems. Houses being fed by well pumps require a lot of electricity. Tankless water heaters also require a significant amount of electricity and special wiring. This combined electrical requirement is too much for many homes to handle.
Still unsure? An expert plumber from Arnold & Sons can evaluate your home’s needs and make a recommendation based on daily usage, household size, and layout.

Tankless Water Heater Value FAQ

Are tankless water heaters good for large families?
Yes, tankless water heaters can be good for large families as long as they are properly sized. However, some families require multiple tankless water heaters to meet their water needs.
