a) Do you have a link to it?
b) How much energy does the hypothetical coffee maker draw? "1 coffee
maker" is a nonstandard unit and it's hard to compare it with 5 kW.

I have been seeing ads for a portable plug in electric fire place that
uses as much electricity as a kitchen coffee maker but puts out 5000
watts of heat. Has anybody checked this out from an o.u. perspective?
A coffee maker takes about 1900 watts, This ties up a 20 Amp circuit. If
the heater's out put is anywhere near 5 KW heat out put, you can resolve
the matter.
You can test this machine in the following manner. Amp meters are for
sale in stores like Home Depot. Get an amplifier, this plugs into the
power supply. The load plugs into it, and the amp meter hooks into the
amplifier which makes the amp meter read 10 times higher, which improves
it accuracy. Find a metallic container with a metallic pot that fits
inside it. place the heater in a metallic container and wrap a bat of
fiberglass insulation around it. place a container of water on the top.
Use a scale to determine an quantity of water and ice, allow most of the
ice to melt. Put this thing together and allow the pot of water to sit
on the heater for a period of time and monitor it's temperature with a
thermometer. Report the results, and we'll do the math.
