A Way To Be Greener
Have you ever wondered how much energy your central vacuum uses in stand-by mode per year? It is a simple calculation with a pleasant outcome.
MD unit transformers draw 16 milliamps. Multiply that times the voltage (120) times 24 hours and you should find around .046 Kw.
Let’s say that your electrical rates are $.14 per kilowatt. At that rate, an MD system costs about $2.35/year. This is the total cost of “ghost” power for the unit to remain in the ready position. If you desire to conserve this energy, the most effective means is to change the electrical outlet for the central vacuum to one that has a switch on the plug. This way, you can turn the unit power on and off whenever you desire to use the low voltage system. If you were building a home and wanted to plan for this conservation, you would locate this switch in the closet where you intend to store the central vacuum hose. Each time you grab the hose you would switch the switch “on” and then the low voltage portion of the inlets would be activated. When you are done vacuuming you would put the hose away and flip the switch “off.”
