A water heater base pad is a rigid foam pad that sits under the tank. It lifts the heater off the floor and reduces heat loss to a cold slab. The collection lists FMI-EPS water heater pads, including a 24" x 24" x 3" grey pad and a 33" x 33" x 2.3" pad. Choose a pad larger than the footprint of your heater and check the thickness if clearance is tight.
Foam pads that sit under water heaters. The collection includes FMI-EPS styrofoam water heater pads, including a 33" x 33" x 2.3" pad and a grey 24" x 24" x 3" pad.
A pad insulates the base of the tank from a cold slab and raises it slightly off the floor. Choose a size larger than the heater footprint, and check the thickness if clearance is tight. Confirm that the heater manufacturer and local code allow a foam pad, since some gas units require a noncombustible base or specific stand.
A pad is an option that reduces heat loss through the floor. Some installations require a pan or a stand instead; follow the heater manual and local code.
What size pad should I choose?
Measure the tank diameter at the base. Pick a pad at least as wide as the tank and review the listed dimensions in the title.
Can I use a foam pad under a gas water heater?
