If you are looking to warm your floors with radiant
heaters and are trying to research what kind of
radiant heaters to install you might find
yourself scratching your head at this point.
There are dozens of products available to purchase, and
there are even more companies telling you that
their product is the best.
So which product is the best?
Should you install a hydronic heating system
that pumps hot water through your floors, an electric
cable heating system, or a low-voltage screen
system? The answer lies in the type of project
you are doing. Not every system is ideal for every
project, but there is an ideal system for every project.
Hydronic Heating Systems
Hydronic floor heating is the
oldest and most popular type of radiant floor
heating. These systems are comprised of a boiler or hot
water heater, pumps, manifolds, PEX tubing,
thermostat, and either gypcrete (a concrete-like
material) or wood panels. Hydronic heating is the most
complex of all radiant heat systems. These systems
require trained professionals to design and
perform the installation. Your best economies of
scale are achieved for hydronic systems in large areas
or entire homes because of their expensive
components and operational costs.
Hydronic systems can be installed under any
type of flooring. Most hydronic systems require hot
water tubing to be installed in a 2-4″
bed of light concrete and are best installed during
the initial construction because of its weight load
demands and adjustments to floor height. Recent
low-mass products have been developed to avoid
these challenges by fitting the tubing into pre-cut
wood panels, making hydronic systems more convenient and
possible for most major remodeling projects.
If you want to heat smaller areas
like a bathroom or kitchen, a hydronic floor
heating system may not be the best value for
your project. The complexity and cost of installing the
system, along with the long-term maintenance and
up-keep required, is not worth the small amount
you will save in operational costs.
Electric Cable Heating
Electric cable heating
systems, often called line- or high-voltage
systems, are gaining popularity and are ideal for
heating smaller areas (10-300 square feet) like
bathrooms, kitchens, and sun rooms. These
systems are comprised of a thermostat and a heating
cable. On some systems, the cable will be
shipped to you as a large spool of cable. These
systems are oftentimes less expensive, and give you the
ability to space the cable how you want and
customize a layout that will heat every square
inch of your floor. Other systems have the cable
attached to a plastic mesh or tape to create a
mat to maintain its proper spacing.
Every available cable system is equally effective, so when
determining which system to purchase, you should look
at the warranty of the product, along with the ease of
installation. Some cables must be embedded in a
separate layer of concrete or mortar, whereas other systems
can simply be installed in the thinset. Most cable
systems can only be installed under tile. However, on
others, if the cable is embedded in mortar or concrete,
any flooring can be installed on top of the concrete. When
heating smaller areas, it is nearly impossible to beat
the simplicity and price of an electric cable heating
system.
