I am looking for a good baseboard heater recommendation. Right now I
see only qmark and Cadet mfg. Both seem to cost about the same.
Im looking for 240v since i hear this will be more efficient? Probably
a 4' or 5' unit. I want the kind the the liquid inside.
Any recommendations or warnings?
The ones with the liquid inside cost about 3 to 4 times more than
simple finned baseboard units.
Also, the liquid filled ones really offer no benefits- they take
slightly longer to heat up and to cool off, sort of a "flywheel
However, they are no more efficient, despite frequent claims to the
contrary. Also efficiency is the same, barring minimally increased
line voltage losses, regardless of whether or not a unit uses 120 or
240 volts. The 120 v units are generally portable with limited heat
ouput - limited by the amount of current a typical 120 v circuit can
For example a 2400 watt heater will be as follows:
10 Amps on a 240 volt circuit
20 amps on a 120 volt circuit.
Efficiency is the same.
The units have to be made for a given voltage, they are not
convertible from one voltage to another.
You can buy a 240 volt 4 or 6 foot unit at the Depot for around
$40-$60, plus thermostat. The more expensive units are no better.
QMark has a raceway above and below the heater element so it's easier to
daisy chain from one to another through conduit. If using the raceway above
the element (which is more convenient), you'll need some higher temperature
wire. They already have their two wires in there rated at 125 C. I purchased
some Teflon insulated wire rated 200 C. The Cadet doesn't have a raceway in
their residential units so all wiring would have to be in the wall instead
of conduit between heaters unless you buy commercial units. I used the
thermostats that mount on the heaters. Line voltage wall thermostats are
also available. Mine are 240 volt and I'm satisfied with the result. They
are quiet, heat up quickly. I didn't go with the liquid filled. I didn't see
that liquid filled would offer any advantage whatsoever, and they cost much
more, something to consider not only for the initial installation but also
for future replacement.
But flywheels are useful no? The liquid stabilizes the temperature so
it does not swing so fast. Thus you should not have as many on/off
cycles. Plus it will keep the area around the heater generally warmer
through constant radiation.
a 240 will use less current which is gentler on my fuse panel.
Some can be changed just like some table saws. Yes, the wattage is
telling the power consumption. So long as the amperage is in line, the
efficiency will be the same i agree.
Interesting opinion. Ill have to consider that.
True and for an area where the temperatures will remain stable, it would
tend to even out the temperature a little over the short term, but the
overall swing will be determined by the thermostat, so with oil filed you
might cycle between 69.5 and 70.6 over 20 minutes and with a standard heater
you might cycle between 69.5 and 70.5 over 10 minutes.
The non-oil filled will have the ability to react faster to something
like an open door and will have less tendency to overshoot the set
One *big* advantage of hydronic electric baseboard heaters is that
they operate at considerably lower temperatures, greatly reducing
(eliminating?) any potential fire risk, as well as the burn hazard to
young children. These lower operating temperatures also correct
another problem often associated with standard baseboard heaters --
the black streaks or carbon deposits on painted surfaces immediately
above the heater. And they do offer greater comfort in that they
continue to radiate heat long after the element has shut off, thereby
minimizing any temperature swings.
Now, I'm not sure of this next point [hopefully someone can confirm or
correct me on this], but I believe you can safely locate these units
directly under electrical outlets, something I know you can't do with
conventional baseboard heaters.
Years ago, I had liquid-filled electric baseboard heaters in a summer
home (they were made by InterTherm, which I believe is now Cadet). If
I were ever to install electric heat again, this is the way I'd go;
there's absolutely no question in my mind this type of heater is well
worth the extra premium.
You could be right; people might imagine a system driven by a
conventional or electric boiler, as opposed to a self-contained
"liquid filled" electric baseboard heater. That said, if you were to
do a Google search using the words "hydronic electric baseboard"
enclosed within quotation marks, you would see a number of hits,
including one that takes us directly to Cadet's home page, a major
manufacturer of these products. So, in my defence, if I'm misusing
industry standard terminology, I'm not alone. ;-)
