If you are remodeling your home or apartment buildings, or building from the ground up, you can cut renovation and construction costs for adding a laundry room by installing a ventless dryer. This type of dryer does not require a dryer vent in order to dry clothes. Because no vent is needed, you do not have to worry about cutting holes in the walls, running vents to the outside, and dealing with building codes, fire codes, and such construction headaches. Further, since there is no outside vent into the home or apartment, it keeps squirrels, chipmunks, mice, birds, and other small animals from trying to get in through the vent opening.
Insurance rates are typically lower for homes that have a ventless dryer, compared to those with conventional vented models. The reason why your rates could be less is because you never have to worry about lint depositing in the vent, which creates a fire hazard. You also do not have to spend money hiring a professional to clean your dryer vent annually to keep it clean and clear of any deposits.
A ventless dryer uses one of two different types of technologies, depending on whether it is a stand-alone model or a combination washer dryer model. Stand-alone models normally use air-to-air drying. This involves drawing in air from the room at normal air temperatures. There are two different air circulation systems inside the dryer. One section heats the air and passes it through the clothes; the other cools the air and extracts moisture before returning the heated air back to the drum. The other method uses cold water condensation technology, where the water cools the air and extracts the moisture.
