Water Heaters: Tankless vs Tanked

Water Heaters: Tankless vs Tanked

Are you thinking about installing a new water heater? Then maybe it’s time to replace your old storage tank model with a tankless water heater. Here’s what you need to know about tankless water heaters — and five signs that it might be the right choice for you!

How Does Each Water Heater Work?

Both systems heat water in two different ways. Here’s how they work:

Tank: a burner with 30-50 gallons burning at 40k BTU’s. This burns all day long so your hot water is ready when you need it.

Tankless: the heat exchanger slows water burning at 200k BTU’s and only heats water when you use it.

This gives you two different energy calculations…

Tank: 65% efficiency. For every dollar you spend, 35 cents is lost.

Tankless: 95% efficiency. For every dollar you spend, 5 cents is lost.


Depending on installation costs, a tankless model variance is approximately 12-15 years. Tanked water heaters really don’t calc at 25+ years – much longer than warranty. This brings us to the expected lifespan of each system. Longevity of a six-year warranty or 15-year warranty. A tankless water heater can last 20+ years, while a tank model can last 6-10.
