FAQs

First, measure the actual heated area, not the total square footage of the room. Do not lay heating cables under cabinets, furniture or appliances.

Next, decide on heat output. When installing Mapeheat Cable with Mapeheat Membrane: A 3-pillar spacing in Mapeheat Membrane produces 10 W per sq. ft. (low output), which is not typically recommended but is acceptable for low-use areas when trying to stretch coverage. A 2-pillar spacing in Mapeheat Membrane produces 15 W per sq. ft. (high output), which is best for installations on a concrete slab or when heat loss is a concern. An alternating pillar spacing of 2-3-2 in Mapeheat Membrane produces 12 W per sq. ft. (standard output).

When installing Mapeheat Cable with Mapeheat Cable Guides: A spacing of 3" in Mapeheat Cable Guides produces 12 W per sq. ft. (standard output). Alternating spacing of 3"/2" in Mapeheat Cable Guides produces 15 W per sq. ft. (high output), which is best for installations on a concrete slab or when heat loss is a concern.

Always default to the lesser square foot on the chart.
