Tank vs Tankless Water Heaters in Utah

A tank water heater costs less up front and is simpler to maintain. A tankless water heater costs roughly twice as much installed, never runs out of hot water, lasts about twice as long and saves floor space. In Utah, tankless only pays off if you also deal with hard water, either with a softener or a yearly descale.

Side by side

• Installed cost (estimates): tank $1,800–$3,500; tankless $3,500–$6,500
• Typical life: tank 8–12 years; tankless around 20 years with maintenance
• Hot water: a tank can run out; tankless is continuous but limited in how many fixtures it can supply at once
• Maintenance: tank needs a yearly flush; tankless needs descaling, yearly in hard water
• Space: a tank takes floor space; tankless hangs on a wall

Choose a tank if

Your current tank meets your needs, you want the lowest upfront cost, or your gas line and venting would be expensive to upgrade.

Choose tankless if

You run out of hot water, you plan to stay in the home long enough to benefit from the longer life, or you need the space. Plan for a softener.

Utah-specific sizing

Tankless output is rated by how many gallons per minute it can heat through a given temperature rise. Utah’s winter groundwater is cold and gas appliances lose output at altitude, so a unit that looks adequate on paper can fall short in January. Size for winter.
