What Are Short and Tall Water Heaters?

Short and tall water heaters are two of the most common types of residential water heaters. Short water heaters are typically shorter in height and wider in diameter than tall water heaters. They’re designed for use in small spaces, such as closets or under counters, where vertical space is limited.

Tall water heaters, on the other hand, are taller and narrower than short water heaters. They’re often used in larger homes or commercial buildings where space is less of a concern.

Use this chart as a guide to help you determine which type of water heater is right for your household’s specific needs and preferences.

When it comes to choosing between a short and tall water heater, there are some numerical data that can help you make an informed decision. Here are some examples:

Tank capacity: Short water heaters typically have a tank capacity of 30 to 50 gallons, while tall water heaters can range from 40 to 100 gallons or more. This means that if you have a larger household or higher hot water demands, a tall water heater may be a better option as it can hold more water.
Energy efficiency: Energy efficiency is an important factor to consider when choosing a water heater as it can impact your monthly energy bills. According to the US Department of Energy, a high-efficiency gas water heater can save an average household up to $100 or more per year compared to a standard model. Tall water heaters tend to be more energy efficient than short ones, as they have a larger surface area for heat transfer and can heat water more efficiently.
Upfront cost: Short water heaters are generally less expensive to purchase and install than tall ones. According to HomeAdvisor, the average cost of a 40-gallon short water heater installation is around $1,100, while a 50-gallon tall water heater installation can cost around $1,500. However, it’s important to note that this cost can vary depending on factors like location, installation complexity, and the specific model of water heater you choose.
Ongoing cost: While short water heaters may be less expensive upfront, they may cost more to operate over time as they have a smaller tank and may need to heat water more frequently. According to the Department of Energy, water heating accounts for about 18% of the average US household’s energy bill, so choosing an energy-efficient water heater can help reduce your ongoing costs. Tall water heaters may cost more upfront, but they can save you money on your energy bills in the long run.
