PROPER INSULATION PROMOTES HEAT RETENTION
When WarmlyYours oor warming systems are installed on a concrete
slab, we strongly recommend adding a layer of insulation to the slab prior
to installing the radiant oor heating system.
Some of the heat that would otherwise be transferred to the ooring
surface will remain in the slab, causing the oor’s surface temperature to
be considerably lower. This is true with any oor warming system.
When installed on top of a concrete slab without insulation, it is generally
accepted that a radiant oor warming system will take the chill away from
the oor and provide a small amount of warmth.
Adding insulation on top of the slab and beneath any oor warming system
will allow a greater percentage of the heat generated to transfer to the
ooring surface. This leads to greater efciency and therefore faster warm
up times, higher expected surface temperatures and lower energy usage.
The oor will have the capacity to warm to a comfortable temperature, and
in some cases can be employed as the primary heat source for that room.
