hot wax box

I have started to build a hot wax box for xc skis.
I am having trouble to find a heater that goes to 55 degrees Celsius.
The one I have is a 4 foot baseboard heater made by UNIWATT 750 W.
The heater does not heat passed 25 degrees. It cuts out.
I did disconnect the internal thermostat but it still stops at about 24
degrees.
Anybody have an idea what could be done to get this thing to heat up to
50 degrees?

Thanks,
RW

I made one last summer using a regular, $15 hairdryer, bought at
wallmart, connected to a fairly fancy digital thermostat that had
shutoff temperatures in 1 degree increments up to about 200 F. It took
some time (say, 20 minutes) to warm up, but it maxed out (no control by
the thermostat) at close to 140F/60C. My whole college team used it
for a season with good success and its still going strong. I suspect
eventually the hairdryer will die but since its so cheap, no problem.

To control the heater
check this http://www.hammfg.com/pages/climate_...thermostat.htm
part number no SKT011409NC, the maximum is 140°F / 60°C
It's just plugged with the 120v and your UNIWATT or any kind of electrical
heater

Ciao Jake,

Could you please tell us the manufacture and part number for the
thermostat.

Thanks much.

Hi Hank,
the thermostat (actually considered a temperature control, apparently)
I used is made by Johnson Control, model A419. You can find it he

I found it difficult to find a temperature control that had a small
temperature differential, but also had an upper temperature limit that
was high enough. I also wanted one that would run on regular AC line
voltage, not on some lower DC voltage, because that simplifies the
wiring a lot. I just wired an extension cord to the thermostat, so I
plug the male end of the cord into the wall, and into the female end I
plug my hairdryer. I suppose you could set up a system like this for
cheaper (the thermostat goes for about $85), but it would take a fair
amount more electronics know-how and actual work.

Thanks Jake.

While we are talking hot boxes, I will add an additional thought.

When I finally get around to building my hot box, I will include some
sort of fail-safe provision. With only one thermostat, if the
thermostat fails closed, the hot box will overheat and the skis will be
toast. One approach would to have two thermostats wired in series.
More expensive, but cheaper than buying new skis.
