Water Heater Installation in Long Island: A Step-by-Step Homeowner Guide

Every home needs a reliable hot water supply for everything from morning showers to washing dishes. If you’re thinking about getting a water heater installed in Long Island, NY, you probably want to know what will happen. This guide will show you how to do it step by step, whether your old unit broke down or you want to upgrade to a bigger or more efficient one. Retro Hot Water & Heating is a family-owned business that has put in hundreds of water heaters in Nassau and Suffolk counties. We think that happy customers are those who know what they’re getting into, so let’s talk about how a typical water heater installation goes and some things to keep in mind that are specific to Long Island.

How to Pick the Best Water Heater for Your Home

The first step is to choose the right size and type of water heater for your needs. Most homes on Long Island use either traditional tank water heaters (40 or 50 gallons is a common size for a family) or tankless systems that heat water on demand. Each one has its own set of pros and cons:

  • Tank water heaters are cheaper to buy at first and heat water ahead of time, storing it for later use. Newer models are much more efficient and have better insulation than older tanks, which means less heat loss when they are not in use.
  • Tankless water heaters give you unlimited hot water and free up space by getting rid of the big tank. They often save energy by only heating water when needed.

Think about how many people live in your house and how you use it. Do you often run more than one shower or appliance at the same time? You might need a bigger tank (or a tankless unit with a higher GPM). Our Retro team often tells customers that heating water is usually the second most expensive thing in a home, costing between $400 and $600 a year on average. If you choose a model with a high Uniform Energy Factor (UEF), you can lower that cost. For example, a water heater that has the ENERGY STAR® certification will use less energy and save you money over time.

A tankless unit can save floor space by being mounted on a wall if you live in a home without a basement (some Nassau communities have slab foundations). If your home already has a chimney vent system, though, a direct replacement tank heater might be easy to install. The type of fuel is another thing to think about. Many areas of Long Island have natural gas, but if you live in an area that doesn’t have gas (like some homes on the East End or North Shore), you might use oil or electric models. If you don’t have natural gas, you could also use propane.

At Retro Hot Water & Heating, we help you weigh these options. We’ll calculate your peak hot water demand, consider the NY climate (yes, incoming water is colder in winter, so slightly larger capacity or BTU input might be recommended), and suggest the right unit. We supply top-quality brands and ensure the model meets New York State efficiency standards and local code requirements.
