Choosing a
System Guaranteed to Boost Everyone’s Bottomline
While
hydronic heating solutions have been around for awhile,
electric radiant heat solutions are quickly
gaining in popularity, and with good reason.
Regardless of project scope, whether your client is a
homeowner or a residential builder, they’re
looking for greener, more efficient ways to add to
their bottomline. Both electric and hydronic
radiant heating systems do just that. But
which system offers more value?

The cost of
electricity in America varies between 3 cents/kWh up to
18 cents per kWh; consequently, the cost of
generating 1,000 BTU with a hydronic system is
generally lower than the cost of generating 1,000 BTU
with an electric system. However, the real or hidden
cost is in the operation of each system.
To be
effective, hydronic floor heating systems are run
continuously for several months, while electric
radiant heat systems run on cycle times, making
them more flexible.
Why such a
huge difference in performance? At the time of
installation, hydronic systems are typically
placed 1.5" or 2" into a cement slab, deep into
the floor, and require 4 to 7 hours to heat up surfaces
from the time the system is first turned. To avoid a
long stand-by times, more consumers choose to
leave their hydronic
floor heating system on for the winter,
continuously consuming energy for a much longer
duration. In contrast, electric radiant heat is
usually installed above the sub-floor, just under
the flooring material, and can heat a floor in 30 to 60
minutes (under tile). An electric radiant
floor heating system will only use
electricity continuously for the initial period of
temperature build-up. Once the electric radiant
heat system achieves the appropriate temperature,
it will then cycle on and off, drawing electricity
during 25 to 33 percent of the time remaining
during a given cycle.
The size of the job can play an equally
important role in your recommendation of
radiant heating solutions. In remodeling jobs or in
select rooms of a new construction project, hydronic
systems will cost more to install. In very
large jobs (complete home in new
constructions), hydronic radiant floor heating
systems will often be less expensive to
install. Generally speaking, the upfront investment
for equipment, labor and floor height issues make
hydronic systems cost prohibitive in small
to medium sized areas. In larger areas that invoke
the benefit of economies of scale to work, hydronic
systems make sense if oil or compatible fuel
costs are low enough to offset the upfront
and residual maintenance costs. So, if you are
retrofitting a residential driveway or
heating smaller rooms as a part of a home
improvement project, choosing electric radiant heat
will save your customer several thousand
dollars.
Let’s say you are asked to install
radiant heat as part of a bathroom remodel.
The $300 to $400 required to install an electric
radiant heated floor will cost $4,000 to
$5,000 dollars for hydronic radiant heat.
That’s because hydronic systems require a boiler,
which will eats up a big chunk of that
installation budget. Unlike electric radiant
heated floor mats, hydronic floor heating systems
also elevate the floor by a couple of
inches, a significant difference that can
cause big problems for you during your bathroom
remodeling job. Radiant heated flooring
installed will elevate the floor by only ⅛ of
an inch. The installation costs, plus
complications associated with the difference
in floor elevation, could mean the difference
between a satisfied customer and a
logistical nightmare.

Because they are maintenance free, electric
radiant heat solutions are still a viable
choice for projects, both large and small. Hydronic
systems are prone to sedimentation, mechanical
problems and maintenance issues that are
hard to detect, and costly to fix. Electric radiant
heat systems include fault detectors, allowing you
to quickly pinpoint a cable break and repair
it in a minimally evasive manner. Consider
energy saving cycle times, low installation costs
and installation flexibility, electric
radiant heat is one sure way to add value to any
project and win repeat business.
