How much does water heater installation cost on Long Island?

Tank water heater installation in Nassau County typically ranges from $1,500–$3,500 installed. Tankless systems run $3,000–$6,500, and heat pump water heaters $3,500–$5,500 before the federal IRA tax credit. Every quote is upfront and includes removal, permits, and startup.

Should I replace my tank with a tankless water heater?

Tankless units save 20–30% on hot-water energy, last 20+ years (vs 8–12 for tanks), and never run out of hot water. They cost more upfront and may require gas line or venting upgrades. We'll show you the side-by-side numbers during your free estimate.

How long does water heater installation take?

A standard tank-for-tank replacement takes 2–4 hours. Tankless installations typically take 4–8 hours, longer if a new gas line or venting is required. Most homes have hot water back the same day.

Do you remove the old water heater?

Yes. Removal and proper disposal of your old water heater is included in every installation quote. There are no disposal or recycling fees.

What brands do you install?

We install Rheem, Bradford White, A.O. Smith, Navien, Rinnai, and Noritz. Rheem and Bradford White are our most-recommended tank brands for Long Island homes thanks to long warranties and strong parts availability.

Do I need a permit to replace a water heater in Nassau County?

Yes. Nassau County and most municipalities require a plumbing permit for water heater replacement. We pull the permit and handle the inspection as part of every installation.

Is a heat pump water heater eligible for tax credits?

Yes. Hybrid heat pump water heaters that meet ENERGY STAR Most Efficient criteria qualify for the federal Inflation Reduction Act (IRA) tax credit of up to $2,000. We'll confirm eligibility for the model you choose.

Do you offer financing on a new water heater?

Yes. We offer multiple financing tiers through Synchrony, including 0% APR with approved credit. Apply during your free estimate — there's no obligation.

Signs You Need a New Water Heater

Water heater is 10+ years old

Most tank water heaters fail between 8–12 years. Replacing before failure prevents leaks and water damage.

Rusty or discolored hot water

Rust inside the tank usually means the anode rod and tank lining are corroded — replacement is the safe option.

Visible leaks around the base

A leaking tank cannot be repaired. Acting quickly avoids flooding and finished-basement damage.

Not enough hot water

Sediment buildup or an undersized unit reduces usable capacity. A right-sized replacement restores full performance.

Rising energy or gas bills

Old units lose efficiency every year. A modern high-efficiency tank or tankless cuts hot-water energy use 20–30%.

Strange popping or rumbling sounds

Hardened sediment is overheating the tank bottom — a strong predictor of imminent failure.
