My personal experience is 5 10 a month cost to run my garage refrigerator and she s an old beast.
How much energy does old garage door use.
The variance of external temperature.
This gives it around 1 100 to 1 400 starting watts and 550 to 725 running watts.
Uses less than a watt while standing by waiting for the signal to open.
The amount of energy that a garage door opener uses is very small.
The door can be heavy but usually uses counterweights or springs so that the motor isn t lifting a 300 lbs.
Door from a dead stop.
Uses 445 watts while opening or closing the door including the 108 watts used to power the light bulbs.
Current energystar models use only 30 60watts for a 40 tv so those 4 hours asleep cost you about 2 cents.
Because garages are typically unconditioned space the potential energy savings from better insulated garage doors is significantly reduced.
This equates to 364 000.
Refrigerators built prior to 1993 could use as much as 3 times the energy than a newer energy star certified fridge.
If your home has a garage there is a good chance that you have an automatic garage door opener.
Because these electrical appliances operate for only a few minutes per day they don t use much electricity to open and close your garage door.
The condition of the door seals.
Most door openers have cycle of only a few seconds.
Considering you ll probably only use your opener a couple minutes each day this power consumption is fairly negligible.
Older garage door openers have a standby power draw as high as 14 watts.
It takes say 10 seconds to open or close.
On the other hand it will have a substantial impact on the overall energy wasted for the building that has the automatic door open button.
I ve been looking for information about garage door openers and their wattage.
Not enough to notice.
If you have an old tv however it can consume as much as 400w in that case your nap costs you about 15c.
Doesn t seem like such a minor thing anymore does it.
That doesn t sound too terrible.
It turns out that doesn t cost you too much thanks to modern tvs.
I ve found very little information lots about their light bulbs though but another yahoo.
If we just open these public doors ourselves it will not have a big impact on our personal energy level.
Kw cost in your local.
I have a double wide door.
So one cycle open or close consumes 343 watts for 10 seconds comes out to be 57 watt minutes 95 watt hours.
No there is no energy star specification for garage doors.
