Eden PURE Quartz Infrared Portable Heater

They use electric, so anyone who buys one could save money IF they're lowering the heat in the rest of the building, or IF they have to keep the heat higher because a certain room isn't warm enough, AND their current energy source costs them roughly the same per btu as electric.

Before someone buys one, they need to do the math. How much is the initial cost of the heater? How much colder will they keep the rest of the building? How many btus are they saving? What is the cost of their current energy source? What is their current electric cost?
