Local installed pricing for tank gas ranges from $800 to $2,000, tank electric $900 to $2,200, tankless $1,500 to $3,500+, and heat pump $1,800 to $4,000.

What affects water heater replacement cost in Southlake?
The price range depends on the type of unit you choose: tank gas or electric are more affordable, while tankless and heat pump models cost more. Labor rates reflect the high local income level, and permit fees add a small fixed cost. If your system is a closed loop, an expansion tank is required, which adds to the total. The age of your home (median built 1997) may mean older plumbing or gas lines need updates, increasing labor time.
