Heat Surge "Amish-made" fireplace

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

I don't need no steenkin' heat surge. I'll just plug in my wife's hair dryer and point it at my feet to warm 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.

russ_watters

Hmm - that seems pretty common. Wonder what tha's about.

mgb_phys

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

Ivan Seeking

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.

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?

"---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.

turbo

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

Ivan Seeking

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.

turbo

10 HP on a 120V residential circuit? Let go of my leg, scammer!!!

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.

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.

Ivan Seeking

The point is:

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?
