The short answer
In Schenectady, NY a standard 40 to 50 gallon gas or electric water heater installed by a licensed plumber typically runs $1,400 to $2,400 in 2026. Tankless gas units installed run $3,800 to $6,500 depending on venting, gas line size, and electrical work.
Hybrid heat-pump electric water heaters (Rheem ProTerra, AO Smith Voltex) typically run $3,200 to $4,800 installed, and can qualify for federal energy credits.
What changes the price
Fuel type. Gas units cost more than electric because they need venting and a sediment trap, but operate cheaper. Electric is the lowest install cost on most existing electric setups.
Size. A 40 gallon tank is right for most 2-3 person homes in Schenectady. A 50 gallon fits most families of 4. Going to 75 gallons adds roughly $400 to $700.
Code upgrades. If your old install was pre-2010, you may need an expansion tank, updated T&P discharge piping, or a new shutoff valve. Budget $150 to $400 for these.
Venting. Power-vent and direct-vent tanks cost more than atmospheric units, but are required in tight basements with combustion air problems.
Haul-away and permit. Apollo Brothers includes both. Some companies charge $75 to $150 extra for each.
Tank vs tankless in Upstate NY
Tankless saves on long-term operating cost and never runs out of hot water, but the upfront cost is roughly double. For a 2 person household it rarely pays back. For a family of 5+ with high hot water demand, tankless makes financial sense in 7 to 10 years.
In a Schenectady winter, incoming water can hit 38°F — make sure your installer sizes the tankless unit for that worst-case rise, not for the manufacturer's marketing number.
How to avoid getting overcharged
Get the install price in writing before work starts — not a verbal estimate.
Confirm the model number and warranty term in the contract.
Ask whether permit, haul-away, expansion tank, and new shutoff are included.
Verify the company is licensed and insured in New York.
