What you're paying for

What is usually included: The tankless unit, new stainless venting, gas line upsizing if needed, isolation valves, condensate drain, removal of the old tank, permit, and 4–8 hours of labor.

What moves the price:

Gas line size — most tanks run on a 1/2-inch line and tankless units often need 3/4-inch, which can add $500–$1,500
Venting: condensing units use cheaper PVC venting than non-condensing stainless
Unit size (GPM) matched to the number of bathrooms
Electrical outlet needed near the unit, and a recirculation pump if requested
Permit and inspection

Whether the gas line and venting must be upsized/rerouted (biggest swing), BTU capacity, condensing vs non-condensing unit, electrical outlet for the unit, permit, and old tank removal.

Frequently asked

Is $2,500 a fair price for gas tankless water heater installation in Florida?

Yes. $2,500 is right around what most homeowners in Florida pay. Anything from $534 to $5,500 is inside the normal range for a licensed plumber; above $5,500 it is worth getting a second quote.

Why do quotes for the same job vary so much?

Gas line size — most tanks run on a 1/2-inch line and tankless units often need 3/4-inch, which can add $500–$1,500. Venting: condensing units use cheaper PVC venting than non-condensing stainless. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.

When should I get a second quote?

Any time a quote lands above $5,500, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
