Bathroom Exhaust Fan And Energy Efficiency

What a Bathroom Exhaust Fan has to do With Energy Efficiency

Most people do not pay much attention to bathroom exhaust fans until the boogers and cobwebs are hanging half way down to the commode. When the fan gets plugged up, energy efficiency is lost and the exhausting power of the fan is reduced to almost nothing. The normally efficient fan motor heats up, wastes electricity, and applies unneeded expense to the power bill. If your bathroom exhaust fan cover looks like a Kansas dust bowl and the fan motor will no longer hold up a piece of toilet tissue, it's time for a little preventive maintenance.

What is a bathroom exhaust fan?

Mounted in your bathroom ceiling or exterior wall, the bathroom exhaust is given the job of removing moist or awkwardly perfumed air from the room. If moist warm air remains in the room – the possible occurrence of mold and mildew is greatly increased. By removing the moist warm air produced by a shower or bath, the relative moisture is reduced as is the possibility of mold. And, of course, removing the awkwardly perfumed air from the bathroom simply allows the bathroom to be used by the next person sooner.

Does a bathroom fan have a rating system?

Yes, a bathroom fan is rated according to cubic feet per minute (cfm) and according to how noisy they are. A less expensive apartment model will be rated at 50 cfm and about 4.0 sones. 4 Sones is the sound of a normal Tv, 3 Sones like office noise, 1 Sone is the sound of a refrigerator, and 0.5 sones like rustling leaves.

Some bathroom exhaust fans have humidity sensors that turn the fan on when moist air is present and then turn the fan off when the air is refreshed and no longer holds noticeable moisture.

Which bathroom exhaust fan would be best for my bathroom?

I would recommend a bathroom exhaust fan rated at 100 cfm or more and a sone level of something around the level of rustling toilet paper. I would also recommend you install a timer switch so you can leave the fan running after you leave the bathroom and have the fan turn itself off about 20 minutes later.

A ceiling fan has a duct attached that is designed to take the warm moist air and discharge it into the great outdoors. Be sure the duct is firmly attached to the fan and that the duct terminals outside and not just into the attic space.

How does a fan waste energy and increase my power bill?

Ceiling fans are dust collectors. Combine the flow of exhausting air with the moisture content of the air and you have a dust collecting system. One, the fan is good at collecting and holding dust, grit and grime and two, the ceiling fan is mounted in the ceiling and hard to see and hard to reach and clean. The ceiling fan becomes the forgotten appliance.

With accumulating dust, the motor and fan will struggle to maintain speed and effectiveness. The motor works harder, runs longer, gets hotter and uses more electricity than it needs to. The exhaust fan turns slower and the electric meter spins faster.

Recently, I was in a home where the homeowner insisted the bathroom fan was working well. I stand under the fan, a test square of toilet paper at the ready, as he turned the fan on. You know how an electric motor can make a humming sound and not do anything. He thought the fan was working since it made a nice humming sound, but the fan was not turning and not exhausting anything. I held the TP square up to the fan and then watched it gentle float to the floor.

Can a ceiling fan earn the Energy Star Efficiency Rating?

Yes, ceiling exhaust fans are rated by the Energy Star program and can earn an Energy Star rating. As with any appliance, look for the Energy Star rating and then look further to see how efficient the appliance is within that rating. One Energy Star ceiling fan may noticeably more efficient than another Energy Star rated fan.

Do remember, to maintain that efficiency, the fan needs to be installed and ducted correctly.

Hollinshead and Kirkham, originally of Burslem in Staffordshire, moved their pottery works to nearby Tunstall in 1890. They catered mainly for the middle class end of the market and, in the main, produced a range of conservatively designed dinner ware. However in the economic slump following the First World War the company needed to do something to address their falling sales. Designer Harold Growcott was their White Knight.

Growcott came up with a range of designs for hand painted porcelain that tapped into the growing interest in all things Art Deco. The designs featured an abstract painted background of two or more colours on which bold fruit or floral designs were hand painted. The result was bold and exciting.

The Delicious Dozen as it came to be known was actually a range of 14 designs, but let's not be pedantic about a good nickname. The designs were applied to many of the existing pre-war shapes, to give them a new lease of life, as well as some fresh new shapes more in keeping with the Art Deco style. Due to its similar subject matter and large bold painting style H&K has also been dubbed 'Poor Man's Moorcroft' but if the prices I have had to pay for some of my pieces are anything to go by, that's not a title that fits today's collecting market.

This is the major collectible area for this pottery. Hey made many dinnerware designs, many of them very attractive but none of any real collector interest (except, of course to people who have a set handed down to them from their grandmother). But the Delicious Dozen have become extremely popular in recent years and if you come across a piece you will understand why.
