Can Cozy Heat be used as a primary heat source for an entire building?

Yes. The MI Cozy Heat cable — at 11.5–20 watts per lineal foot — can provide sufficient heat output for total space heating in residential and commercial buildings, including cabins, homes, basements, sunrooms, commercial buildings, and industrial facilities. System design targets 5–15 watts per square foot of heated area depending on the building’s heat loss characteristics, insulation values, and climate. The Cozy Heat system is designed and specified by Heatizon’s team to meet each project’s heat loss requirements — not sized to a generic formula.
