Which one fits your house?

Three questions. Your answers copy into the form.

Question 1 of 3

What fuel is at the heater now?

When a tank makes more sense.

You need hot water back fast. Gas and a vent are already in place. The budget is tight. A 40 or 50 gallon tank has kept up fine for years. In those cases, a like-for-like water heater replacement is usually the right call.

When tankless makes more sense.

You plan to stay for years. You want the floor space. Back-to-back showers run a tank cold. You can add gas capacity and a new vent. Then a tankless water heater in Layton is worth a quote.

FAQ

Tank vs tankless: FAQ

Is tankless better than a tank in Layton?

It depends on how you use hot water. Tankless avoids standby loss and lasts longer.^[2] A tank is simpler and cheaper up front. Cold winter water and hard water both matter here.^[3]^[4]

Do tankless water heaters run out of hot water?

Not the way a tank does. But they can only heat so many gallons per minute. Too many fixtures at once means cooler water.

Which lasts longer?

Federal guidance gives tanks about 10 to 15 years and tankless up to about 20.^[1]^[2]

Which is easier to install?

A like-for-like tank. Tankless usually needs gas line, vent, and condensate work.

Which handles hard water better?

Neither likes it. Tanks build sediment. Tankless units build scale in the heat exchanger. Both benefit from flushing and a softener.
