Reliable Water Heater Services in Long Island: Installation, Repair & Replacement
Few things are as essential to your comfort as reliable hot water. Long Island Heating and Cooling Service INC specializes in all types of water heater services, ensuring you have steady, efficient hot water when you need it most.
We service, repair, and install the four most common types of residential and commercial water heating systems: Storage Tank (Gas and Electric), Tankless (Demand), and Indirect Water Heaters.



Types of Water Heater Systems We Service
Gas Storage Water Heaters
Gas water heaters use a gas-fired burner located at the bottom of the storage tank. The heat rises, warming the water inside. This is a highly popular option across Long Island for its relatively quick recovery rate and efficiency compared to older electric models.
Electric Storage Water Heaters
Electric water heaters use high-voltage electric heating rods (elements) submerged vertically inside the tank to heat the water. These are a great choice when natural gas is not available or preferred. Our technicians handle element replacement, thermostat repair, and full Electric Water Heater Installation in Long Island.
Tankless Water Heaters (On-Demand)
Also known as demand-type or instantaneous water heaters, tankless units heat water only when you turn on a hot water tap.
- Savings: They eliminate the standby energy losses associated with keeping a large tank of water constantly hot, which can lead to significant cost savings over time.
- Convenience: Their compact size makes them ideal for smaller homes or spaces where storage is limited.
- Endless Hot Water: Because they heat water on demand, you are far less likely to run out of hot water.
We are experts in Tankless Water Heater Installation and Service, helping Long Island homes achieve maximum efficiency.
Indirect Water Heaters
Indirect water heaters are an excellent choice for efficiency, especially when paired with a high-efficiency boiler or furnace.
Instead of having its own dedicated burner, an indirect system utilizes your main furnace or boiler to heat a fluid. This fluid then circulates through a heat exchanger coil located inside the well-insulated storage tank, warming the domestic water supply. If paired with an efficient heat source, this setup can often be the least expensive method of providing reliable hot water.
