Radiant Panel-Concrete Slabs On Or Below & Above Grade With Under Slab & Edge Insulation

Radiant panel concrete slabs can offer a more economical radiant panel assembly if concrete slab's are already planed to be incorporated as part of a building's floor assembly. Concrete floor under slab insulation preferably high-density foam should be used with this type of radiant panel assembly to help minimize downward heat loss, especially slab on grade applications. In some circumstances, the downward heat loss with slab on grade application can equal 25%+ of a rooms total heat loss.  High-density foam insulation is best suited for under slab application. Advantages of using under slab insulation include lower initial heat load, lower operational cost over the life of the system and quicker response time. Concrete radiant slabs operate at lower supply water temperatures on average then any other type of radiant assembly. The ability to use lower water supply temperature's offers a more efficient radiant heating system when combined with a modulating condensing boiler or the appropriate mixing device that incorporates outdoor reset control. Concrete radiant panel heating & cooling systems are the most efficient type available.
