Commercial Radiant Heating Under Concrete Floor

Concrete flooring is one of the most widely used type of flooring in commercial buildings. Its durable and can last for decades but it is also cold and unwelcoming. With STEP Warmfloor you can transform your property into warm and inviting area.


Under Concrete Commercial Heating

STEP Warmfloor heating elements can be used under concrete flooring.

Radiant heating under concrete eliminates hot and cold spots in building and provides even, quiet, draft-free heat all year long. Your concrete floor will be comfortable for guests and employees any time of year, no matter the season. Concrete has excellent thermal properties which allow it to act like a stored heat "thermal bed" that is slowly released into the space as heat losses occur until the stored heat is exhausted. This makes concrete an energy efficient flooring choice for use with radiant heating systems. STEP Warmfloor heating elements provide the greatest versatility for slab heating allowing for a tailor-made system design that best fit your specific comfort, wellness, and operating needs - and it is easy to install.

Commercial Concrete Underfloor Heating Installation

STEP Warmfloor heating elements can be placed under the slab, in the slab (topper slab), or on top of the slab underneath the finished floor. Whether your slab is below grade, on grade, above grade or a high-rise floor slab, STEP Warmfloor heating elements are appropriate for all applications. Where the heating elements are located in relation to the slab and finished flooring affects the performance of the system with regard to response time, consumption, and operating duration. When a faster response time is desired, it is ideal to place the heating elements above the slab and on top of insulation. If consumption efficiency is the primary goal or having the ability for stored heat in the event of a power failure event, placing the heating elements under the slab on top of insulation is best. This allows the concrete mass to act like a stored heat "thermal bed" that is slowly released into the space as heat losses occur until the stored heat is exhausted.

The insulation must be strong and stiff to avoid pavements bending or cracking under heavy load and traffic. Consult with insulation manufacturer for deflection/load characteristics and for maximum allowable live and dead load limits. The heating elements should not be in direct contact with many aggressive solvents, construction adhesives and foil faced insulations. This also includes plasticizers and other concrete additives used to help the concrete flow smoothly during installation, or for curing time purposes. For pouring applications, a 6-8 mil plastic sheet should cover the entire surface area on top of the heating elements.
