Water Heater Types Domino Installs
Conventional Tank Water Heaters
The familiar cylinder in the basement, gas-fired or oil-fired, that keeps a tank of water hot around the clock. It is the simplest replacement when a tank already exists, because the venting, the gas or oil line and the water connections are usually in place. A like-for-like swap is often done the same day.
Tankless Water Heaters
A gas tankless unit heats water on demand as it passes through, so there is no tank to run out and no standby loss. It suits a gas house with high hot water use and a place to run the venting. Sizing matters: a unit too small for the number of bathrooms gives a lukewarm shower when two fixtures run at once, so the technician sizes it to the house rather than to the box.
Indirect Water Heaters
An indirect heater is an insulated tank with a coil inside, fed by the boiler. The boiler heats the coil and the coil heats the tank, so the water heater has no burner of its own. On a Long Island boiler house it is often the best choice: far more hot water than a tankless coil in the boiler, long tank life because no flame touches it, and one burner to service instead of two. It works with oil and gas boilers alike.
Replacing the Coil in an Oil Boiler
Many oil-heated houses make their hot water through a tankless coil inside the boiler. It works until lime builds up inside the coil and the shower runs lukewarm, or until the boiler is replaced. At that point the choice is a new coil, which the parts repair and replacement page covers, or an indirect heater beside the boiler. The technician explains both at the estimate, with the price for each.
Oil-Fired and Gas Water Heaters
A house with no gas service can still have a standalone oil-fired water heater, which uses its own small burner and shares the oil tank with the boiler or furnace. A house with gas has the widest choice: tank or tankless, in the sizes that fit the household. Domino installs and services both fuels, and the same technicians handle the burner side of an oil-fired heater on every tune-up.
Water Heater Brands
You get a unit whose parts are easy to find on Long Island and whose maker stands behind it. Domino installs all main brands, including Bradford White and Rheem, and services whatever is already in the house. The brand recommendation follows the house: the fuel, the venting, the space and how much hot water the household uses.
Signs the Water Heater Is Due for Replacement
- Water on the floor around the base of the tank, which means the tank itself has started to leak.
- Rusty or discolored hot water, with the cold water running clear.
- Hot water that runs out faster than it used to, or never gets as hot.
- Rumbling or popping from the tank as it heats, which is sediment on the bottom.
- A pilot that keeps going out on a gas unit, or a burner that locks out on an oil-fired one.
A leaking tank is a replacement, not a repair. The others are worth a service call first, because a thermocouple, an element or a flush is far cheaper than a new heater when the tank itself is sound.
Water Heater Installation Cost on Long Island
The price depends on the type of heater, its size, the fuel, and any venting, gas piping or boiler piping the installation needs. A like-for-like tank replacement is at the low end and a tankless or indirect installation is higher because of the extra work. The number comes from a free, written, on-site estimate with no obligation.
Financing is available through Wisetack, subject to its terms; the financing page explains how it works. Every other Domino price is on the pricing page.
Water Heater Installation From the Same Company That Heats the House
The technicians who install the water heater are the same NORA-certified technicians who service the boiler or furnace next to it, 24 hours a day. If the heater is part of a bigger job, such as a conversion to gas or a boiler replacement, it is priced on the same estimate and installed on the same visit.
