Modern Day Advanced Bathroom Exhaust Fans - What Are Your Options?


Gone are the days when bathroom fans worked poorly and made too much noise. Unlike these less efficient models, the modern day appliances are far more energy efficient and makes almost no noise while operating. For instance, there are bathroom exhaust fans featuring water heaters. When it comes to such kinds of appliances, there are some things that you need to be aware of. We're about to explain the nitty-gritty of such advanced models.

First thing's first, ensure that you get a bath fan which is equipped with a heater. If you're able to handle the installation all by yourself, then you should go ahead and do it. But if you can't do this, find an experienced electrician who has the skills needed to do it.

You'll have to consider the issue of the appliance's capacity, in terms of the volume of air it is able to move. It's measured in Cubic Feet per Minute (CFM). It is better when this number is high. This means that the model will exhaust much more foul or damp air from the room.

It's suggested that you select a powerful fan. Surely, more power will result in spending more money. This is the reason why it makes great sense to take your budget into consideration. Still, don't even think of hitting below 50 CFM anyhow. Modern models, which are equipped with water heaters, are made especially for areas, which already have a bathroom exhaust fan, but it's a poor performer.

Besides, there are models equipped with lights. These help you get rid of the moisture more effectively. The whole process is automatic, so you won't have to do more than turning the fan on, if the humidity seems high. Modern models are very sensitive as they have sensors to gauge the humidity level. Thus, these bathroom exhaust fans get turned on automatically when the humidity level goes up.

Bathroom Exhaust Fan And Energy Efficiency


What a Bathroom Exhaust Fan has to do With Energy Efficiency

Most people don't 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 humidity 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 T.v., 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 terminates 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 stood 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 maybe noticeably more efficient than another Energy Star rated fan.

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

Bathroom Exhaust Fan - Does Your Bathroom Need Extra Ventilation?


Most modern houses are designed to include adequate ventilation. You may notice the importance of this during the winter when windows are often kept shut and the house is heated. The hot air rises and when it condenses will turn to moisture. This allows mold and bacteria to breed and can soak into the foundations of the building. The mold and mildew is a potential hazard for the inhabitants of the house and the damp is a potential hazard for the house itself. Thus it is important that ventilation allows the air to circulate and hot air to be released.

This is certainly no more true than in the bathroom and the kitchen. The bathroom is constantly being used and this generally means using hot water for a shower, bath or shave. This causes hot vapor or steam that will rise to the ceiling. When the temperature drops in the bathroom, this steam will condense and leave moisture. This is a potential health hazard and again is not good for the long term maintenance of the room itself. Thus modern bathrooms, especially those with showers come with a bathroom exhaust fan. This article will discuss ventilating the bathroom and some things to consider in the ventilation fan.

A bathroom ventilation fan removes moist air from the room before it can condense and leave moisture on the walls and ceiling. It can also remove smells from the room. The fan is normally set to activate whenever the shower is turned on or even the ambient light. It is then set by a timer to continue running for a few minutes after the shower is turned off. This can be set on installation and changed if the air is not being removed effectively. New modifications on this include using a humidity sensor that keeps the fan running until the moisture reaches a certain level. This is probably more efficient, in terms of electricity usage, than the standard timer set up.

The industry standard for a bathroom ventilation fan is that it should be able to remove eight times the volume of air in the room every hour. This means you have to work out the volume of air that is contained in your bathroom before buying a fan. This can be done by getting the dimensions of the room (width x length). Bathroom exhaust fans are rated by cubic foot per minute. Depending on the size of the bathroom, you may also have to take into account the number of fixtures, like shower, bath, tub, sink and toilet in the room.

Another consideration of ventilation, especially during the summer months or during the day, is that you can simply open a window for ventilation. This will decrease the length of time the fan has to run for or you can switch it off for the summer. It is important to get the right fan for the size of room as it can make a rather annoying noise. If the fan is too big or room too small (or both) you might find that it makes your experience in the bathroom unsatisfying.
