Tankless

Water Heater Dimensions

Tankless water heaters are gaining popularity among homeowners due to their energy efficiency and space-saving advantages. Unlike a traditional water heater, a tankless water heater doesn’t store a large volume of hot water.

Instead, it heats the water as you use it, providing a continuous supply of hot water. While selecting a tankless water heater, it’s important to consider their dimensions, as they differ according to the type and model of the unit.

This article will discuss tankless water heater dimensions, including electricity-powered, gas-powered, and standard electric tankless water heaters.

Electricity-Powered Tankless Water Heaters

Electricity-powered tankless water heaters are installed on walls and take up less space than gas-powered water heaters. Their dimensions are smaller compared to gas-powered heaters, but they boast higher water capacities.

Most electricity-powered tankless water heaters can be installed on the wall, making them an ideal choice for homeowners who want to save floor space. These units are widely available in various sizes and shapes, giving homeowners a range of options to choose from according to their hot water needs.

Gas-powered tankless water heaters are commonly used in residential areas as they are known for their energy efficiency and lower operating costs. They have a compact design, with dimensions of 10 inches deep, 18.5 inches wide, and 26 inches high.

These units need a direct vent to the outside of the building for optimal combustion and venting. Ensure that there’s ample space available to install the vent pipe before purchasing a gas-powered tankless water heater.

They don’t need venting or additional space for combustion air, allowing them to be installed in small spaces such as closets or under sinks. Standard electric tankless water heaters are a great choice for homeowners looking for an energy-efficient solution and have limited space.

Space Requirements for Water Heater Installation

Installing a water heater requires adequate space, considering the dimensions of the unit and the diameter of the water tank. Here are some space requirements to consider when installing a water heater.

Gas-Powered Water Heaters

Gas-powered water heaters need space for air circulation around the unit to remove exhaust fumes safely. The National Fuel Gas Code stipulates that there needs to be at least 12 inches of space on all sides of the unit.

This means that if you choose a gas-powered water heater, make sure there’s enough space in the room or closet you plan to install it in.

Diameter of Water Tank

The diameter of the water tank determines the amount of space required to install the water heater. Standard water heaters range between 18-25 inches in diameter.

However, modern tankless water heaters are typically smaller in diameter, ranging from 10-15 inches. Make sure you measure the space where you plan to install the unit and compare it to the dimensions of the water heater you plan to buy before installation.

Conclusion

Purchasing a tankless water heater requires careful consideration of the dimensions and space requirements. Keeping in mind the factors discussed above will help you pick the right water heater for your home.

Whether it’s a gas-powered or electric-powered water heater, it’s crucial to ensure that you have enough space available before purchasing the unit. Be sure to measure the available space correctly before buying, and you can enjoy the advantages of a tankless water heater.
