If it gets colder than 20f outside, does your thermostat maintain the set temp?

What you did is becoming more and more common. Esp now with gas/heating oil getting so high. A lot of new builds do this now as backup if one, electric/gas/oil, get to high you have the other to fall back on.

My apt is terrible, we can set the apt to be 60 and it will sit at 58, we can set it for 65 and it will be at 58. It just cannot get past 58. It's quite terrible, the inefficiency of the furnace is just mind boggling. I do enjoy the $250 heating bills ... thank gawd I have roomies.

So yea, its set at 58, but that's the warmest part of the house. I'm guessing my room (upstairs) is 55. A bit chilly for my taste, I'm used to low 60's but nothing sweats and a slanket can't handle :D

Here in NC last night it got pretty cold.
The heat pump didn't use the aux heat though that I'm aware of.
Its pretty easy to tell when it does, large bright blue light on the thermostat when it uses aux heat.

The unit is only about 2 years old though and my average utility bill is about 60.00.
Thermostat set on 68F.



Want hot ?
My grandmother, when she was still alive at the age of 93, would be sitting in her living room, near a 3-brick gas heater with the weather outside in the 60's. That room had to easily be 100F+ . She felt it was just right though :)

Mine is set at 60° max.

60 is way too cold for warm blooded creatures, especially those with young children. I keep mine @ 68-74 depending on the time of day. Thats borderline too cold as well.

If that's too cold for warm blooded creatures, then what am I? I don't have any rugrats to worry about.

I have a heat pump in FL, my house has had no problem maintaining 73 degrees for the past two days (was in the 20's last night).

It's been great so far. House stays at the temps we set.

Waiting to see what the utility bill's like for Dec., though. It was the first month where it was consistently cold.

It is strange......... In the winter, it seems as though 75f is perfect, but in the summer when the AC is on, 71--72f is comfortable.

I like it warm in the winter and cold in the summer ;)

Anubis---- Your hands must be pretty stiff when the Temp is 68f inside. Unless you wear gloves while typing messages here on Anandtech.
I wake up to that Temperature because that's what I set it at before I go to bed, but when I get up and set it to 74-75f, and sit at the computer to type......... It's MOLE-ASSES Slow until I warm up!

I'm not getting on your case, it's just that some people prefer Warmth in our fingers when typing.
Everyone's diff. :)

Yours and vi_edit's points are perfectly sound .........

So, what's the best all around sys. for Heating and Cooling? I suppose it's not a Heat Pump if you live in TN.

Need Suggestions please.

Geothermal heat pump.
