Is Radiant Heat?
Project Spotlight... The Northwest Maritime Center
heating is widely regarded as the most comfortable,
healthiest, and most natural heating process available.
People are warmed in the same way as they are warmed by
sunshine on a cool day. Floor drafts, cold spots, and dry
air are eliminated. Dust, air contaminants, bacteria, and
low humidity levels, all problems associated with forced-air
heating, are nonexistent in a home with a properly designed
radiant heating system.
is Radiant Heat? Hold your hand over a hot cup of coffee and
feel the heat.
The typical conclusion is that heat rises.
Typical maybe, but incorrect! "Hot air" rises but "heat" can
travel in any direction. That is why you can feel the heat
of the cup when you place your hand to the side of it.
Radiant energy transfer is caused by a warm surface giving
up its heat to a cooler surface. Whenever there is a
temperature difference between two surfaces, both surfaces
will attempt to equalize. Radiant energy travels through
space without heating the space itself. It only turns into
heat when it contacts a cooler surface. Our human comfort
relies just as much on radiant heat transfer as it does on
air temperature, yet the majority of heating and
air-conditioning professionals think only in terms of air
the past 50 years Americans have typically heated their
homes by blowing warm air from ceiling mounted registers.
This crude attempt at warmth sacrifices comfort for over 200
days of the year in the Puget Sound region. With a forced
air system, because warm air rises and cold air sinks, it's
always cooler on the floor. The average contractor will
rarely inform you that ducted air systems have the lowest
comfort rating and the highest monthly energy costs of any
heating system. The contractor simply installs the system in
the home because it costs less initially. Period.
Radiant Floor Heating more comfortable?
body temperature is warmest at our head and circulation is
poorest at our feet. That's why the human body is most
comfortable in a room that is warm at the floor and slightly
cooler at head level.
air heating systems which blow scorched air are the exact
opposite of what the human body requires -- hot at the
ceiling and cold at the floor.
Radiant Floor Heating it is also easier to zone heat your
home or building. Work areas can be kept at a comfortable
working temperature, while bedrooms can be kept slightly
cooler for sleeping. At the same time, living rooms,
bathrooms and entrances can be kept slightly warmer.
who want a truly comfortable living environment specify
radiant floor heating. By controlling both the air
temperature and the radiant transfer of heat to nearby
objects, radiant systems deliver a comfort that is
are radiant heating systems superior to forced air systems?
Air is a horrible conductor of heat. While the air coming
from the vents may be warm, it does not warm the objects in
the room or radiate that warmth throughout the room. A
hydronic radiant heating system takes advantage of the
superior conductive properties of water to more efficiently
heat your home by heating the objects in it.
A home with quality radiant heating has supreme
comfort, far lower operating costs, is absolutely silent,
and builds equity. The slightly higher installation cost of
a radiant system is always offset by the lower heating
bills, not to mention the supreme comfort provided by a
hydronic radiant heating system.
In commercial buildings and factories, Radiant Floor
Heating increases productivity and helps reduce health
problems associated with working on cold, damp floors. In
barns you won't have any drafts and the floors will be warm
and dry. In nursing homes and hospitals, the warm floors
mean the highest comfort for the occupants. Management of

associated with radiant heating.
used to carry heat. Water is one of the best conductors of
heat; it can be circulated positively and its temperatures
can be accurately controlled so you get a more even heat
with less temperature fluctuations.
Whether you have hardwood, vinyl, carpet, ceramic
tile, or concrete floors, they'll all be "barefoot warm" for
the most comfortable living and working environments.
