A Timer for Baseboard heaters?

Hi All, I have baseboard heaters on the lower floor living room for
additional heating (the gas furnace blows down from the ceiling).  The kids
use the room in the evening for homework, surfing the net, etc. Problem is,
the darlings have trouble remembering to turn down the T-stat when they
leave the room  (strange as it seems).
My question is, can I put a wind-up timer on the wall (similar to a hot-tub
or sauna)?  Also, can I put the timer on the T-stat wiring (preferred) or
right at the 220V wires on the heater (220v = Scary).  A nice 1hr timer
would keep everybody happy.   Tanks

Like these?


You could switch either 240V with a DPST timer, or
just a 24V thermostat lead with a SPST timer
(do you have a 24V thermostat?)

I will check the voltage of the thermostat, but yes these are perfect
"Spring Wound "Bypass" Timers".  Just what I was looking for, thanks

You would have to use a timer or thermostat with contacts rated for
the full power of the baseboard heater. I looked into this to pre-heat
my bathroom in the morning but couldn't find a timer that could handle
the current. I bought a Holmes bathroom heater with a timer, GFCI and
tip-over switch.

In my opinion, there's a better way. I did it for my house when
we lived in the country and were leaving early, getting home late.
I wanted a setback system, but each of the heaters were on their
own separate breaker, with each being controlled by a thermostat
located at the end of the heater strip(s) per room.
So I set up a series of 7 1/2 watt bulbs (Christmas Tree Lights)
inserted into the thermostat portion of the heater. It was tricky
them in there and still being able to change them. So later on I
two in series at each heater, with both of them in the space close to
the sensor. The warmth of the bulbs caused the heater to turn off,
the bulbs being series-wired kept them from burning out. Problem was
that they didn't kick on till the house temperature got down to about
but it was too much of a PITA to change their positions a bit further
away from the temperature control to give them a higher setback
temperature. I considered putting a resistor in series with the
of lamp sets, but was never sufficiently motivated. That's all right,
worked great, the bulbs lasted forever, and my setback system was
simply a timer set to stop running the bulbs about an hour before the
time we expected to get home.  When we went to bed, we set it for
the time of the following afternoon.
And certainly, we had a different one for the bathroom. Wall mounted
timer, I would get up earlier and turn it on, went back to bed. When
I got up to take my shower, it was still kinda cold in there,
for the wife who would turn off the timer when she left the bathroom,
if she forgot it would turn itself off about the time we left the
if I didn't notice and turn it off.
By the way, when we built that house, it had 2x6's for the walls,
6" insulation batts. And we insulated all the interior walls. It was a
'package home', through Lowe's . They called it the Low E home.
I understand they don't offer it anymore, but they should.
