About Tankless Water Heaters


As homeowners get more creative with their use of space, one way to save room throughout your home and often money is to install tankless hot water heaters. Ace Hardware carries tankless water heaters to supplement your current system or whole house tankless water heaters to replace it.

Rather than working to maintain set hot water temperatures in a reservoir throughout the day, tankless water heaters heat water “on demand”. Since it’s unnecessary to store hot water between usages, these no tank water heaters save on energy costs and can be installed close to a water source. Smaller models can even be hidden within a bathroom vanity.

Tankless water heaters typically come in gas or electric variations. While gas models often require a professional hook up, some homeowners opt for electric tankless water heaters for more simplified installation. For more information, visit an expert at your local Ace.
