    Default KVAR units

    Does anyone know anything about the KVAR units. They are supposed to save energy. I've found web sites that talk about and sell them.
    I have a neighbor that just installed one. Hopefully I will soon see if they really work.
    They appear to have some type of whole house surge protection but I can't really tell what. I'm about to install a whole house surge protector and don't want to duplicate and/or interfere with the whole house surge protector if I do install a KVAR unit.
    If anyone has any information please let me know.

    Thanks,

    RSCH

    I'm not sold on these units yet. As far as I can tell, they are little more than large capacitors that discharge when there is a sudden surge demand like a motor starting. Although they may have a big affect in industrial settings in controlling peak demand charges, they do not produce electricity or really save electricity they only level out peak demands. Most homes do not have enough motors kicking on and off to realize substantial savings, in my opinion.

    Yep Jack has said it all. Business is charged by demand. and residential is charged by kilowatt hours. save your money

    Everybody is charged for KWH . Large customers are charged for MWH ( mega-watt/ hours ) with possibly a demand charge depending on the type of load .

    First I saw nothing on You Tube about the unit.
    So let's look at savings. Their site says 8% to 25% savings. The unit consist of capacitors and works on inductive loads only (Their own words). My electric bill averages about $80/mo. savings would be $6.40 to $20/mo. if it was all for inductive loads. Lights, TV's, heating units, water heaters,computers, power supplies, stoves, and ovens are all resistance loads not inductive loads so the savings would be far less. Assuming that half my electric bill is inductive loads, pumps, compressors, and fans, it would take up to 15 years for a 200 amp KVAR unit to pay for it's self.
    In a home with electric heat and high electric bills the percentage would be even less because the biggest percentage of the bill is from the resistive heating units. Turning the thermostat down 2 degrees or lowering the water heater temp would result in more savings with no additional investment.

    I am a kvar distributor but before I joined the orginization I was more skepticle about this technology then any one else. It sounded to good to be true..... to make a long video short, Rob and I put our videos on You Tube and you can get them at kvar energy savings unit (vacman1353) We tried our best to be as fair and honest as possible. We show bills, meter readings, the whole nine yards if you have any questions I'll be more then happy to answer them. Rich the vacman

    Yes the kvar unit will serve as a surge protector but most importantly what happened with your neighbors kavr what are her results.

    I'm a meter tech for the local electric utility and have over 35 years in the utility industry. Here's the stratight story.....residential and most small commercial customers are charged for KWH only. The meters we use are tested at unity power factor and at 50% power factor. They must register +/- 100.5% accurate at both power factors. That said, any change in power factor (i.e. KVAR reduction) will have absolutely no effect on a residential bill. For larger commercial customers, we bill for demand and KVARh. In those cases, reduction of reactive power WILL have an effect, and in fact, we require the customer to apply power factor correction. So....save your money. If these devices actually did cause your bill to go down, it means your utility is ripping you off.
