How The System Works
You can feel the heat of a campre even though you are
not directly above it. Radiant energy transfer is caused by
a warm surface (the campre) giving up its heat to a cooler
surface (your body). This radiant energy travels through
space without heating the space itself. It only turns into
heat when it contacts a cooler surface. By transferring this
heat to all of the objects in the room, the heat slowly moves
to warm the air which starts to rise.
Proper Heat Dissipation
All radiant heating systems rely on a “Heat Bank”. The heat
moves from the source (Heating Element) into the Heat
Bank (thin-set) and spreads out and warms the oor without
creating an excessively hot spot. In the WarmlyYours
Floor Heating System the thin-set and/or self-levelling
cement acts as the Heat Bank. It is important to follow the
installation guidelines to create a proper Heat Bank.
Insulation – Proper Heat
Retention
When WarmlyYours oor heating 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.
While WarmlyYours systems provide up to 25% more
heating power per square foot than the nearest competitor,
the slab will always act as a “heat sink.” 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 heating system.
When installed on top of a concrete slab without insulation,
it is generally accepted that a radiant oor heating 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
heating 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.
Securing The Roll(s)
Once the roll(s) is tted into the space, it needs to be
secured to the suboor to prevent movement during the
installation of the oor covering. The options for securing
the roll(s) are discussed in detail on Page 5. Regardless
of the method you choose, it is vital that the integrity of
the Heating Element be maintained. Staples should never
cross, pierce or nick the Heating Element. Minimum 2 in.
spacing between adjacent heating devices.
Protecting The Heating Element
It is vital that proper care be taken to insure that the
Heating Element is not damaged during the installation of
the system or by the oor covering. A thorough preparation
and detailed inspection of the suboor will assure that any
and all objects that may damage the Heating Element are
removed prior to installation. Heavy gauge cardboard or
carpet scraps should be used to protect the system from
trafc during the ooring installation.
Never Cut The Heating Element
The key to the system is the uninterrupted ow of
electricity through the Heating Element.
Control Device Options
Option 1: Programmable
Thermostat
The SmartStat has an in-oor
sensor and a digital display
that indicates the exact oor
temperature. It also features a
manual set-back to a “high” and
a “low” temperature level, and a
built-in GFCI. The programmable
function allows you 4 setting
changes for each day of the week.
Its maximum capacity is 1800
watts at 120 VAC or 3600 watts
at 240 VAC . Any oor requiring
more power will need to be zoned
with more than one SmartStat™
and a Relay Contactor or with a
Master Thermostat and Power
Modules.
Option 2: EasyStat
Non-Programmable Thermostat
The EasyStat™ has an in oor
sensor just like the SmartStat™,
but requires no programming.
Just enter the oor temperature
using either Fahrenheit or Celcius.
It is equipped with a GFCI and
is available in 15 amps at both
120 volt and 240 voltages. A oor
requiring more power will need
to be zoned with more than one
SmartStat and a Relay Contactor
or with a Master Thermostat and
Power Modules. We recommend
an inside wall, away from
sunshine.
