I wish somehow I could tell the world that any electric 115V consumer
electric space heather, whether $15 or $500, can only produce a
maximum of 5200 BTU. Outlandish claims for the Evenpure and others are
totally fraudulant!!!

It's a bit like these miracle weight loss devices/pills: They always add in
small font "along with a healthy diet and exercise", which of course is where
the weight loss comes from.

Most of the major companies marketing these heaters are careful to say that the
energy savings comes from switching from whole house heating to spot heating,
while implying that there is something special about their spot heater.
