Can Warmup Electric Heating be Installed in a Shower?
Heating Mats – DWM
When installing a Warmup mat or cable in a shower, it must been between two non-combustible materials.
Install the Warmup heating system on top of the sloped pan if shower base is a poured mortar bed. Then, skim-coated with thin-set and tile over. Do not install Warmup directly over the rubber moisture membrane. We also advise against embedding Warmup in the mortar bed as long heating times could ensue.
In the case of building panels such as backer-boards or WEDI systems, you can install Warmup mats and cables directly over the boards. Please refer to the corresponding installation manual for more information.
