My boss likes to turn the office heat totally off at night, which means we have to blast the heat all day and endure a freezing office in the morning until the heat warms the space. It’s a purely financial decision on his part, but I’m not certain he’s right, I just can’t prove it. My theory is that if we just turn the heat down at night; then turn it up a little in the morning, we will actually be saving energy because we’re maintaining a level temperature instead of having to blast the heat all day. I need to back this up, but can’t find anything online to support my theory.
it is more expensive to do it your boss's way. personal experience.
Does anyone have any ideas for stopping (or minimizing) heat transfer through a sliding glass door?
I live in Phoenix, AZ. I own a condo with a sliding glass door to the backyard. During the day I can feel the heat coming through the glass. I have vertical blinds on the door that stops some of the heat, but it still gets really hot in the room.
The door is in the shade 95% of the time...it's mostly just the hot air. So putting an additional shade in front of it won't do much good.
Any ideas of additional methods for keeping out the heat? Anything I can add/put onto/put in front of the door to slow down the heat transfer?
Thanks!
I recently screened a house in Texas. I choose the "No Seeum" material for all of the screens. There was a significant drop of temperature in the house afterward. I choose to do the job myself, purchased the materials and took a Saturday to do 18 screens. Once you do the first one, the job becomes easier. My GF couldn't believe the difference. I did the screen on the backdoor first, so that she could see and feel the difference as it was slide open and closed.
The other option would be to coat it with UV protective window film. You can find it in the same stores you would find the screening materials, LOWES, HOMEDEPOT, ACE TRUVALUE, or most any good hardware store. You can choose tint percentages and mirrored or unmirrored finishes.
Either way, you will see a noticable decrease in your electric bill. Her's dropped by nearly 22% during February.
I hope this helps.
If you really want to see a change, do both to your windows.
I understand copper is a great thermal conductor. Does this also mean it holds in heat longer? What materials have the greatest heat retaining qualities?
No, just the exact opposite. Because it's such a good conductor, it carries heat away from itself exceedingly well.
But, in general, the materials that prevent heat from moving are not the materials that you wish to have for storing heat. Consider a hot lunch; wouldn'y make much sense to eat stryrofoam, would it? But, you'd use styrofoam to keep your hot lunch hot, or your cold drinks cold.
Styrofoam is a great insulator. The best insulators today are vacuum sealed aerogels. You can read the article in Wikipedia. The vacuum prevents thermal conduction, while the sealant prevents radiated heat loss.
I am planning on buying a better terrarium for my snake and I planned to use florescent fixtures for light and a CHE for heat. I am trying to decide what wattage I need. So does a CHE provide the same amount of heat as a heat bulb with the same wattage?
