I was mainly wondering what shape the sine wave output would have to be for that to add up.

We can guess...

300W should be the output rating (why not in VA?). 650VA could be the peak VA requirements during line drop-out conditions.

I can't wait for summer when I can by my Amish Frost Bite richy appointed in shimmering icicles.

I must be missing something here. 2 HP is 1660 W, assuming a 90% efficient motor (and assuming that a 2hp motor actually provides 2 HP when attached to a vacuum cleaner - there is no reason to expect that it must). That's easily within the range of a household circuit.

 Quote by mgb_phys I just bought a 300W UPS that is also labeled 650VA
Hmm - that seems pretty common. Wonder what tha's about.

(1660W/0.9)/110V = 16.75A aren't 110V circuits 15A in the US?

Not only that, many so called 2 HP vacs are only rated at 6-10 amps, at 110VAC. [I did time in a vacuum store while in college].

I think I've seen the 2HP Peak rating on motors that use as little as 4.5 amps, at 110VAC.

Electrical service, outlets and power cords are rated in amps. The common household outlet is 15 amps. It could be fused for less. 117V*15A > 2HP.

Motors are rated in HP and duty. It could be still be a 10 HP shop vac rated at 100% duty, if their were such animals, and be fine running off a household outlet. The pump just cant load the motor over 2HP--for very long.
 Blog Entries: 3 i think 15A is a common breaker size now for wall outlet circuits. in the past, larger size fuses may have been used. few enough and large enough to be fire hazards. wall outlets in an actual "shop" in a commercial building may be another story, though. do we have an electrician in the house?
 From CTV British Columbia http://winnipeg.ctv.ca/servlet/an/lo...hColumbiaVideo "---despite the headline --these heaters are not made by the Amish: they're made in China. If you read the ad carefully, you realize that only the wood mantle is made by Amish craftsmen." I'm outraged. I want my electronics made by Amish, and my woodwork done in China.

Me, too. And I want the UL labels to be counterfeited by Native American printing shops.

It is still meaningless if they don't cite the voltage at which the peak HP is reached.

Also, to be rated for 10 HP, the plate rated maximum current would be exceedingly high [on the order of 70 amps], which you never see.

 Quote by Greg Bernhardt The video on the website is just flat out ridiculous.
Note that in the video at heatsurgetv, they state: "Don't be fooled by glorified space heaters".

Those would be the ones that sell for $14 to$50, or so, and produce just as much heat.

 Quote by Ivan Seeking http://www.heatsurgetv.com/ http://www.heatsurge.com/ The problem? These sell for up to $587.00 but are just a 1500 watt electric heater plus the fancy "Amish-made" cabinet. A 1500 watt electric heater like this sells at Walmart for less than$14.00 http://www.walmart.com/catalog/produ...uct_id=7768641 Note that the Heat Surge cited maximum of 5110 BTUs, is just 1498 watts.
The two products aren't comparable. Walmart is selling a heater, strictly designed for that function. On the other hand, this amish company is selling a furniture piece, and oh yeah it can also heat your house. I'm sure there are lots of people out there who would pay $500 for a hand-crafted amish cabnet without the heater.

The point is:

 We were already using all electric heat in this house. With the Roll-n-Glow Fireplace, I believe we still saved money last winter. In a very short time the room heats to the comfort wanted, quietly and cheaper! It's paid for itself already! Rolls Anywhere Slash Heat Bills Christmas Rush Forces Household Limit of 2 Only Uses about 8¢ Electricity an Hour on standard setting
As I said, it may be fair to sell it as a decorative item. But if one wants to save money, this is not the way to go. You will get the same cost benefit by zone heating with any 1500 watt electric heater. The fact that they state, "Don't be fooled by glorified space heaters" while showing photos of inexpensive heaters that provide just as much heat, is extremely misleading. Fooled? How is one being fooled? Who is fooling whom?

That is an interesting piece of datum. I'll have to listen for it. It begs the question:

"How can a blantantly contrafactual statement, such as that, be good advertising?"

Billy Mase (oxyclean and other stuff) has a voice like fingernails on a blackboard, yet his voice is good advertising. Is there a connection?
