It's getting cold here at night (30-50F-and my apologies to those for whom
these temps are a mild spring day) and I'd like to rig up a heater for an
enclosure my sister has for her outside cats.
I have a small electric heater (ceramic, fan) and I'd like to get a t-stat
setup that would allow the heater to come on when the enclosure gets cold,
then shut off if it gets too warm. At the same time I'd like to have this
setup on a timer that would keep it off during the day, say from 10am to 6
A line voltage thermostat in series with a time switch. Timer first.
Here are links to some that do both jobs:

Electric heaters usualy have settings that consume 6-900 and 1500
watts, 1500 watts might cost me near $100 to run a month. Consider a
small heating pad a pharmacy has, they might take 30-60 watts. The
cats can sleep on it and stay plenty warm since the heat will rise
around them. Put a piece of foam rubber under the pad so you dont
loose the heat.
The rate here is 18¢. At 1500 watts, that is 27¢ an hour. If you ran the
heater on high for 12 hours a day, the cost would be about $100 a month.
My guess, though, is that the enclosure can be heated with far less wattage
and less hours per day. In any case, the heating pad idea is probably a
I just checked: for our "non-load-controlled" service we get the first
500kWH per month at 8.8c/kWH and anything over that at 7.8c/kWH. The load-
controlled service (i.e. all the baseboards, dryer and water heater) are
at 4.7c/kWH regardless of how much (or little) we use.
The service fee seems to be a flat $25 per month, then state taxes of $6
and some 'renewable energy' fee that's linked to how much we use (about
$15 for November)
"non-load-controlled" service worked out as 691kWH for November, and the
load-controlled service at 2025kWH.

I'll bet no one sells *discount* electricity to keep cats warm
I think the whole thing is a waste of money and natural resources, but
I'm posting just to say that humans should not sleep on a heating pad.
My mother's came with a warning not to do that, and indeed once she
rolled over in her sleep, ended up on top of it, and got burned. It
took quite a while to heal and I guess could have been much worse if
she had slept that way longer.
Jumping on here, no longer have previous posts. I saw this item and
thought of this thread.
It's a thermostatically controlled "outlet". Might work, might not?
The Thermo Cube is a unique, patented electrical device that plugs
into a standard 15 amp electrical outlet and turns power on
automatically according to outside air temperature, saving money by

Well, it was just a comment that they claim it monitors *outdoor*
temperature; I suspect that it does no such thing, and just monitors the
temperature immediately surrounding the device itself. The manufacturers
themselves claim that it monitors outside air temp though, so it's not
Amazon's screw-up if that's not actually true.
