Water Heater Installation across Nassau & Western Suffolk
Water heater installation on Long Island runs $1,900–$3,400 for a 40–75 gallon tank, $4,800–$7,200 for a whole-home tankless, and $3,800–$5,800 for a hybrid heat-pump water heater before the $2,000 federal IRA 25C tax credit. Most tank replacements are completed same-day across Nassau and Western Suffolk. We install Rheem (our #1 pick), Bradford White (contractor's choice for tanks), Navien and Rinnai tankless, and A.O.

Long Island has hard water, mixed fuel stock (natural gas, oil, propane, electric), and a housing mix that runs from 1920s Cape Cods with utility-closet installs to newer builds with pre-plumbed tankless space. A one-size-fits-all quote misses on all of them. We size for your household demand, fuel type, and venting reality — then install to current Nassau and Suffolk plumbing code, pull the town permit, and file every rebate form on your behalf.
Common signs you need water heaters
Catching these early prevents emergency calls and bigger repair bills down the road.
Failed pilot, thermocouple, gas valve, or heating element. Often diagnosed in one visit.
Failed dip tube, broken element, or a tank that's too small for the household.
Corroded anode rod or rusted tank interior. If it's the tank, replacement is needed.
Cracked tank — non-repairable. Shut off water and gas/power and call us same-day.
Sediment buildup at the bottom of the tank. Flush may help; older units usually need replacement.
Choose the right system for your home
40–75 gallon storage tanks. Lowest install cost. 8–12 year typical lifespan. Best for budget-conscious replacements.
Heats water as you use it. Endless supply, 20+ year lifespan, takes up wall space instead of floor space. 25–35% lower energy bills.
Pulls heat from the air to heat water at 1/3 the energy of standard electric. Qualifies for the $2,000 federal IRA tax credit.
Uses your boiler to heat a separate hot-water tank. Highly efficient if you already have a modern condensing boiler.
