Does adding a ceiling improve temp?


What the ceiling fan does is promote a certain kind of heat transfer known as convection.

Convection is a combination of two other different forms of heat transfer Conduction and advection.

Conduction is simply heat transfer through molecular vibration. When a solid body is heated up, molecules close to the source of the heat vibrate, which in turn causes the molecules immediately adjacent to them to vibrate and so on thereby transferring the energy. Conductive heat transfer is therefore dominant in solids where the molecules are closely packed together thus facilitating this intimate exchange of energy. Gases and liquids simply have too much intermolecular space which prevents them from conducting heat efficiently.

Advection is heat transfer through the bulk motion of a fluid (liquid or gas). While queiscent fluids are in general poor conductors, flowing fluids can simply carry away the energetic molecules from a surface thereby facilitating the heat...

Choosing a Location

This page describes installing 2x4 framing for a new ceiling fan or light fixture if no outlet box exists in the desired location.

To install this frame, first determine where the fixture will be located. If you're installing a new fan, be sure to place it so the ends of the blades are at least one blade length from all walls. Also look for a location that will be near an existing electrical source. For instance, if there's a wall receptacle nearby with available power, it can be used to serve a switch that can then serve the new fixture. Check locating an electrical source and fishing cable for more...

During my research I found a lot of web sites suggesting to run the ceiling fan backwards to circulate the trapped ceiling heat around so that you would feel warmer or to reduce the furnace usage. Some sites made claims as to the disparity of ceiling temperature and floor temperature. My results did not show such a variance.

After reviewing the results I did not pursue moving or circulating the Trapped Ceiling Heat. The aforementioned results did not support my Hypothesis: "If I move the heat from the ceiling, I can raise the overall room temp.", because there wasn't much of a difference in temperature. The cost of moving the air would have outweighed any improvement to the overall results and / or the air would have cooled down to negate any benefits.

Your results may differ. Keep in mind I am heating with forced hot air, perhaps if you heat with wood or force hot water; moving or circulating the Trapped Ceiling Heat may be a viable...

One afternoon, the head of my department caught me in the staff room and posed a musing question.

(He later confessed that he was just curious if he could play puppet-master with this blog. The answer is a resounding yes: I dance like the puppet I am.)

So, do we have ceilings?

The traditional orthodoxy says, “Absolutely yes.” There’s high IQ and low IQ. There are “math people” and “not math people.” Some kids just “get it”; others don’t.

Try asking adults about their math education: They refer to it like some sort of NCAA tournament. Everybody gets eliminated, and it’s only a question of how long you can stay in the game. “I couldn’t handle algebra” signifies a first-round knockout. “I stopped at multivariable calculus” means “Hey, I didn’t win, but I’m proud of making it to the final four.”

But there’s a new orthodoxy among teachers, an accepted wisdom which says, “Absolutely...

The sit and reach is a fitness test that measures the flexibility of your hamstrings, lower back and glutes. To perform the test, sit on the floor with your legs extended out in front of you and your feet against the edge of a sit-and-reach box. With arms extended out in front of you, slowly bend forward at the waist and use your fingers to press the tab atop the box as far forward as possible. To improve the sit-and-reach test, participate in a static flexibility program that specifically targets the hamstrings, lower back and glutes.


To significantly improve your flexibility, participate in a hamstring and glute stretching program one to two times per day. According to Mayo Clinic, your stretching sessions are more effective if your muscles are warm. Complete a five- to 10-minute warm-up period that consists of walking, biking or jumping rope, which will get your blood flowing and increase temperature.


Static stretching involves...

There’s a lot of confusion surrounding attic fans. Here at, we regularly receive e-mails from homeowners with questions about attic fans: What’s the purpose of the fan in my attic? How often should I run it? Do I need a bigger fan?

Before addressing these recurring questions, it’s important to define our terms. First, we need to distinguish between three different types of ventilation fans.

The most common kind of residential ventilation fan is one used to provide fresh air for building occupants. Examples of this type of fan include the fans in a heat-recovery ventilator (HRV(HRV). Balanced ventilation system in which most of the heat from outgoing exhaust air is transferred to incoming fresh air via an air-to-air heat exchanger; a similar device, an energy-recovery ventilator, also transfers water vapor. HRVs recover 50% to 80% of the heat in exhausted air. In hot climates, the function is reversed so that the cooler inside air reduces...
