Tank or Tankless Water Heater: How to Choose

Tank water heaters store hot water and are a familiar, straightforward choice. Tankless heaters heat water as you use it and take less space, but need the right gas or electric supply and venting. The best choice depends on your household. Hot Springs Plumbing & Drains installs both.

How do they differ?

A tank heater keeps a set amount of water hot in an insulated tank. A tankless heater heats water as it passes through, so there is no stored supply to run out.

When does a tank make sense?

A tank often suits a home that is set up for one, where the connections, venting and space already exist. It is a familiar choice for a straightforward replacement.

When does tankless make sense?

Tankless suits households that want to save floor space or that use a lot of hot water at once, as long as the gas or electrical supply and venting can support it.

What does installation involve?

Shutoff valves, connections, a relief line, venting and the gas or electrical supply all need to be right. Hard water leaves scale inside any heater over time, so ask about maintenance.

What should I ask before choosing?

Ask what the supply and venting need, how the heater will be maintained, and how the unit is warranted. Ask us to look at your garage or utility area first.
