Hi,
How much does it break down into KW/h? I pay 7 cents CAD per KW/h.

Just got the bill for this month. I am paying 8.5 cents in US dollars.
Think it was about $ 134 for 1580 KW/h.
This is on the Duke Energy system.
Just me and my wife are living here now. The house is all electric with the
heat pump. I do have a wood stove in the basement but seldom use it.
Sometimes I will fire it up if the lowes are going to be in the low 20s deg
F. at night. Mainly just incase the power goes out. My 5 KW generator will
not run the heat pump. Atleast I don't think it will. I have not looked to
see how much power it will take to run a 2.5 ton unit.
I also have a well so no water if the power goes out.

Okay, you have a good point. I have problems but they don't get
worse when I open the window.

I wish I kept records. I keep receipts but never total them, so I
don't know much.

Hi,
I think you are talking about earlier programmable 'stats. Latest ones
are quite smart. It learns itself to work effectively. Definitely they
save energy. You can even do multiple programming. Only thing I do with
it is I hang it down stairs in winter, I move it up stairs in summer
being wireless programmable one.

Wireless sounds like a good idea, especially since I keep piling
things in front of mine on the wall and can barely get to it.
And then I could have it by my bed at night. I know there have been
times I wanted to adjust the heat.
However if I had wireless, i would lose it like I lost the remote to
one tv 6 months ago. I'm not kidding.
Does it have remote beeping function like some cordless phones?
