Overview - Air Heated Flooring System

The LEGALETT System is a Pre-Engineered Frost Protected Structural Concrete Slab Design used in Residential, Commercial and Institutional Construction. There are Currently Over 20 Million Square Feet of LEGALETT Radiant Floor Heating Systems Installed Worldwide.

The Advantage of an air heated floor

  1. Simple to Install: The LEGALETT system provides for a faster and more efficient site preparation due to the use of a flat gravel bed. The simple installation of the LEGALETT components in the slab also increases installation efficiency. Permanent edging units, which eliminate traditional formwork, allows a short construction time.
  2. Even, Comfortable and Healthy Indoor Living Environment: Due to the LEGALETT foundation’s heat-storage properties, an even stable indoor climate is maintained even when there is a quick change in the weather. LEGALETT ensures warm and comfortable floors while meeting heating needs (building transmission losses).
    The quality of building construction and air changes affect building heating requirements. Modern construction practices together with a Heat Recovery Ventilation (HRV) system and integral in-duct pre-heater offer a very pleasant indoor climate with the LEGALETT system.
  3. Low Maintenance Cost: The closed loop pipe system does not require cleaning or maintenance. The air pipes do not have the leakage risks of a water system. There is no limit to the lifetime of the pipe system. The fan and the heating unit are installed in the closed system with easy access. This allows for ideal operating conditions during the lifespan of the heating unit. Should there be a need for servicing, the unit can be easily repaired or replaced.
  4. Convenient for the Physically Challenged: The low entry height of a slab on grade and the heated floor make the LEGALETT system very convenient for the physically challenged as well as for small children and infants.
  5. Heat during Power Outages: The heat storage system is advantageous in the event of a power outage. Due to the slab’s ability to store energy, it can release its large store of heat over a long period of time.
  6. Construction: As soon as concrete is poured, a Legalett "Construction Heater" is connected to the pipe heating system. This effectively dries out the slab evenly, a process that can continue throughout the construction period. In addition to extending the construction season, this has advantages for the entire building process. Painting and floor laying can be carried out at an earlier stage than with conventional construction methods. (Traditional building heaters need not be used.)
