How does the Presto Power Saver work?
The Presto Power Saver reduces the amount of power drawn from the utility by storing (in its capacitors) otherwise lost electricity (watts) caused by the inductive motors in your home.  (Some examples of inductive motors are air-conditioning units, refrigerators, freezers, washers, dryers, dishwashers, pool pumps, vacuum cleaners, furnace blower motors, fans etc.)  The technology applied by the Presto Power Saver supplies that stored electricity back to your inductive loads, thus causing you to decrease your demand from the utility.  If you decrease your demand from the utility, your meter slows down, and you use less electricity.  The thought is, you’ve already paid for that electricity, why pay for it and waste it when you can pay for it, store, and reuse it again.  This whole process is called power factor optimization.

 

What is Power Factor?
Power factor is the percentage of electricity that’s delivered to your house and used effectively, compared to what is wasted.  For example, a 1.0 power factor means that all the electricity that’s being delivered to your home is being used effectively for its purpose.  However, most homes in North America today have a .77 power factor or less.  This means that 77% of the electricity that is coming thru your meter at your home or business is being used effectively, the other 23% is being wasted by your inductive load.  With a low power factor, the utility has to deliver more electricity to do the same work.  However, the Presto Power Saver increases that power factor in most cases to .97 or .98, thus increasing the effective use of your electricity and lowering your usage.

 

Does the Presto Power Saver work in any home?
Yes it does, as long as you have a circuit breaker panel with breaker switches and not the old screw in types fuses, the unit will work on any single-phase electric application for homes.  One Presto Power Saver works per electric panel in a home.

 

Will the Presto Power Saver affect any of my appliances and their normal use?
No, if anything, your motors will run about 10% cooler, which is good for a motor because heat is the enemy of a motor.

Is the Presto Power Saver tested and approved by independent labs?
Yes, the Presto Power Saver is UL listed and tested, and has also been tested by the University of Santa Clara, California’s Electrical Engineering department.  Also, the technology is recognized by the U.S. Department of Energy.

 

How much can I expect  to save per month by using the Presto Power Saver?
That depends on many factors.  The size of your home, the amount of inductive motor load, and the amount you are paying per kilowatt-hour for electricity etc.  However, generally speaking users of the product have seen up to 25% in reduced consumption, but the average savings is somewhere in the 15% to 20% range.

 

How long will it take for the Presto Power Saver to pay for itself?
Generally about 6-12 moths, but again, the same depends on your electric usage.

 

How long will the Presto Power Saver last?
It has a predicted lifespan of up to 20 years.

 

Why haven’t I heard of this product until now?
That’s easy, two words “cost effectiveness”.  Up until recently, electric rates throughout America were cheap, costing us 2, 3 or 4 cents per kilowatt-hour.  Now, electric rates are 10, 12, 14, and 19.  At the cheaper rates the Presto Power Saver didn’t make sense, but at the current rates, it makes all the sense in the world.

 

What about Presto Power Saver Surge Protection?
As an added bonus the Presto Power Saver practically eliminates power surges throughout the home reducing the chance that a brown out or spike in power will damage your sensitive appliances, it will also reduce other disturbances in the electrical system which is good for home theater electronics, TV's and computers.

Is the Presto Power Saver warranted?
Yes, 5 year Manufacturers Warranty for full replacement.
