ON!

I wake up every morning to a friggin frigid floor even though my apt is a comfy 72
i hate cheap people.

1/3/2008 6:55:39 AM

i don't have my heat on

1/3/2008 6:56:39 AM

If you live below someone you're an asshole (if its under 60 in your place ... 60 is frugal less than that and its cheap bastard territory).

Its impossible to get comfy when you're wood floors are 40 degrees and the tile is even colder
sure the air is 72-75 but that doesn't do much when its all at the ceiling.

wear slippers?

oh well, my upstairs neighbors don't pay my bills

[Edited on January 3, 2008 at 7:17 AM. Reason : it's 57 degrees in my apartment and I'm starting to feel a small chill]

1/3/2008 7:18:34 AM

heated floors ftw.

1/3/2008 7:19:37 AM

actually thats what they're doing right now.


also its a little more excusable in a college financial situation... but i live in an uptown condo worth more than my parents house... Its really not excusable here.


yeah i know bgt when i get my floors re done i'm doing hydronic floor heating.

i'm in lake park, so that's a good enough excuse

maybe thats why they cant afford to turn their heat on...

1/3/2008 8:30:39 AM

maybe they enjoy the comfort of a 60* room?

Solution: wool socks

1/3/2008 9:04:52 AM

wool socks are itchy and still doesn't fix the fact that any heat in their apt is being paid for my apt 101 and i.

Smartwool socks FTMFW

1/3/2008 9:21:15 AM

cold air pools in my room when my door is shut, so it's atleast 5 degrees colder than the rest of the apt when i wake up

1/3/2008 10:09:45 AM

my room is at least 10 degrees warmer than the rest of the apartment. tv, computer, external monitor, lights, the minifrige, and me sharing heat FTW

i bet they bitch about you not turning on the AC in the summer

1/3/2008 10:14:07 AM

well when my roomies are here, they normally take control, since their parents own the apt

when I lived in KP we heated our apartment off of the residual heat from our downstairs neighbors
usually having girls downstairs is good cause they keep it warmer

and if it really got cold we'd just bake something

1/3/2008 10:20:42 AM

you'd been better off just turning on the fucking heat

1/3/2008 10:21:50 AM

why is that?

1/3/2008 10:22:23 AM

an oven is pure resistive heat where a heat pump uses a thermodynamic cycle

that cycle gets you more energy out than you put in compressing the working fluid

the oven if you put in 100 W you get 100 W of heat, a heat pump maybe 100 W in and you get 300 W out (just an example)

you win even more in the winter

hahah i use my a/c too.

do you realize for my floor to get down to 45 its probably in the 30s in their place?
i mean it was 19 when i woke up this morning (outside)

ohh and in the winter when its 20 degrees outside heat pumps aren't very effective and have to go into a defrost cycle frequently. its hard to draw heat out of air with very little heat in it.


[Edited on January 3, 2008 at 10:32 AM. Reason : .]

1/3/2008 10:30:12 AM

except the oven was being used to bake food and eat it

the excess heat warmed the room fairly well

and the act of digestion increases body temperature

I think baking was pretty effective

1/3/2008 10:36:08 AM

^^^don't both of your examples violate the second law of thermodynamics?

you can't have 1+ efficiency

Eff = wout/in = 100/100 = 1 = isentropic
eff = 300/100 = 3 = impossible

1/3/2008 10:37:25 AM

^^no it really wasnt

but if it makes you feel better then ok

^ nothing violates the second law, you arent creating energy you are just moving it from a low temperature region to a high temperature region

pick up a undergraduate mechanical engineering thermodynamics book and you will understand

[Edited on January 3, 2008 at 10:42 AM. Reason : 

1/3/2008 10:37:48 AM

i just don't see how you can have perfect efficiency in one and get more out than you put in in another

1/3/2008 10:43:19 AM

you get to transfer heat from the ground to your apartment, basically--not creating heat directly from the electricity. It takes very little energy to do that when compared to say, heating an oven with electricity directly.

1/3/2008 10:48:09 AM

because I^2 * R losses are perfect from electrical energy to heat energy

and in the second one you are moving energy with the cycle, not creating it

im not going to try to explain it any further

and you are a CE

1/3/2008 10:51:05 AM

haha, that doesn't make it cheap

[Edited on January 3, 2008 at 10:52 AM. Reason : <----has electric heat ]

1/3/2008 10:51:33 AM

one more thing if you dont believe me

turn on your emergency heat, that is just resistive electrical heating and it disables the heat pump

use it for a month and compare it to your previous electric bills

you will see nearly a 10x increase in your electric bill to keep your apartment at the same temperature

actually, you can with a heat pump--it just doesn't happen very often in practice

The air outside contains heat. A heat pump channels the heat from the outside air into your house/apartment/whatever. It doesn't create energy from nowhere.

When you compress a gas it get hot. In a heat pump, refrigerant is compressed in copper tubes and air is blown over it (heat is transferred from the compressed refrigerant to the air that goes in your house). The refrigerant cools. Now it is decompressed and its temperature drops substantially (colder than the outside air). Now heat flows from the outside air into the refrigerant. The refrigerant is compressed and the process begins again.


This has nothing to do with efficiency. Heat pumps do not have > 1 efficiency. They have performance factors > 1 (i.e. they transfer 3 times as much energy as they consume), but the work they perform (pump for the refrigerant and fan to move air) is less than the energy they consume, so they have efficiencies less than 1.

1/3/2008 11:06:06 AM

aight, I guess that makes some sense to me. i took thermo I, but didn't learn anything really. i hated that class

1/3/2008 11:25:57 AM

dude

you just have a BA in econ

you wouldnt understand how much it hurts engineers when regular people do stupid, inefficient things

1/3/2008 11:26:21 AM

lol im not a engineer (biologist) and i feel the same way... it happens all the time...

1/3/2008 11:34:35 AM

Not every one has heat pumps though.

My place has a commercial water heater and hot water heat Which is nice cause i never run out of hot water (more like a boiler than a water heater) and when its friggin cold i can bump up the temp of my supply air rather than a heat pump falling out of its efficient range and producing lukewarm air.

In my case... the oven is gas the water heater is gas my fire is gas...it really doesn't mater how i do it... it all coming from gas...

actually the heat loss from hot water storage probably makes the heater the least efficient way to warm my house.

1/3/2008 11:46:19 AM

Maybe they went out of town for the holidays. I left my thermostat on 40* when I left.

1. save your money

2. buy a house

3. ....

4. profit

They're not.

I'm pretty sure they just can't afford it..
every time i go down there there are those letters from the bank that are really really small
