How they differ
A tank heater keeps 40 to 50 gallons hot and ready. A tankless heater heats water only as it flows, so it doesn't run out, but it can only heat so many gallons per minute at once.
Where tankless shines
- Continuous hot water, with no waiting for a tank to recover
- Takes up far less space and frees up the garage or closet
- Typically lasts longer than a tank heater when it's maintained
Trade-offs to know about
- Higher up-front cost, and many homes need a larger gas line and new venting
- Needs a regular descaling flush, especially with our hard water
- Running several showers and appliances at once can exceed the unit's flow rate if it's undersized
Our take
If your home already has the gas supply and venting, or you value endless hot water and space, tankless is a great upgrade. If you want the simplest, lowest-cost replacement, a new tank heater is hard to beat. We'll look at your setup and give you an honest recommendation with a free estimate for both.
