Most modern houses are designed to include sufficient ventilation. You may notice the significance 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 inherent hazard for the inhabitants of the house and the damp is a inherent hazard for the house itself. Thus it is foremost that ventilation allows the air to circulate and hot air to be released.
This is precisely no more true than in the bathroom and the kitchen. The bathroom is constantly being used and this commonly means using hot water for a shower, bath or shave. This causes hot vapor or steam that will rise to the ceiling. When the climatic characteristic drops in the bathroom, this steam will harden and leave moisture. This is a inherent 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 reconsider in the ventilation fan.
A bathroom ventilation fan removes moist air from the room before it can harden and leave moisture on the walls and ceiling. It can also take off smells from the room. The fan is commonly set to begin 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 facility 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 positive level. This is probably more efficient, in terms of electricity usage, than the thorough timer set up.
The manufactures thorough for a bathroom ventilation fan is that it should be able to take off 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 list the number of fixtures, like shower, bath, tub, sink and toilet in the room.
Another notice of ventilation, especially during the summer months or during the day, is that you can plainly open a window for ventilation. This will decrease the distance of time the fan has to run for or you can switch it off for the summer. It is foremost 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 touch in the bathroom unsatisfying.
