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. (See typical LEGALETT installation)

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.)
