The Vent-Miser is a programmable vent that opens and closes itself based on the settings you have programmed into it. By only allowing warmed or cooled air into a room when it is needed, the Vent-Miser helps conserve energy and keep costs down.
The Vent-Miser should be used to replace an existing AC or central heating vent. The device is compatible with instillation in walls, floors and ceilings. The device can be programmed to make sure that the vent is closed at times of day during the week that a particular room is unoccupied. It is programmed through a simple to use 3 buttoned timer, this timer can be removed from the system to allow it to be programmed with a minimum of hassle. The device uses a battery to power itself and includes a warning light to inform you when the battery is running out of charge.
Though vents can be closed manually, this device does make sure no vent goes unnoticed and is handy for hard to reach vents, or for those with hectic lifestyles. By closing off rooms from the central heating or AC system you allow the heated or cooled air to reach the rooms it is needed in with more speed. This should allow the room with the thermostat in it (which obviously must not have a closed off vent in it!) to achieve idea temperatures without using as much energy, as there is no energy wasted to heat unused rooms. This may not be that noticeable a difference depending on size of house or the regularity of unused rooms.
The Vent-Miser is available for just $21.65 with free delivery.
