Key Factors to Consider When Buying a New Water Heater

The advantage of having a quality water heater at home is clear. Hot water is a necessity in a home—it is used for a number of purposes like cooking, bathing, cleaning or washing, and more. Without a functional water heater, you will be forced to heat water manually, which can be a problem during the cold winter months.

If you’re on the hunt for a new water heater for your home, here are 6 key factors you should consider:

Type of water heater

When buying a new water heater, the first thing you should decide on is the equipment type or model. There are two types of water heater based on construction design: storage tank water heater and tankless water heater. A single-family storage water heater has a reservoir tank that has a capacity of 40 to 60 gallons of water. On the other hand, a tankless model, as its name suggests, does not use a storage tank to heat and store water. It uses a heat exchanger and only produces hot water when you need it.


What is your budget for a new water heater? Answering this question will narrow down your choices to a fewer models. However, aside from the initial cost, it is important to consider the long term cost of running a specific water heater type or model. According to HomeAdvisor, a standard storage tank can cost $400 – $1,600 for a new unit and $150 – $600 in installation cost; while a tankless water heater runs $250 – $2,500 for a new unit and $400 – $1,500 in installation cost. The initial cost of a tankless water heater can be more expensive, but its durability and longer life span can save you a lot of money.


To provide your household with enough hot water to use, you should find the right water heater size. Getting a size too small can cause you to run out of hot water while getting a size too big can bump up your energy bills. According to the U.S. Department of Energy, for a household consisting of 1 to 3 people, you will need a small tank with a capacity of 50 to 60 gallons; for a household consisting of 3 to 4 people, you will need a medium tank with a capacity of 80 gallons; and a large tank for 4 to 6 people.

Installation space

A water heater can take up space in your home, depending on the type and size. Compared to a tank storage model, a tankless water heater takes less space and is easier to install. Homeowners often install their water heaters in the basement where there is bigger floor space and wall space. Water heaters need plenty of space to operate properly. Having a clean and clear space around the system will also make it easier for maintenance personnel to perform their job.

Energy efficiency

A new water heater should help you save water and energy at home and not the other way around. You would want to know the energy efficiency rate of the water heater models you are considering to buy before you make a final purchase. The Department of Energy estimates approximately $100 can be saved per year on energy costs if homeowners use a tankless water heater versus a tank model.
