Exothermic heater ?

Recommended Posts

Posted (edited)

Is there such thing as an exothermic heater in the market, perhaps based on quicklime or similar, for indoor emergency heating as in electrical power outage;  instead of propane heaters ?

Something safe to health, that when activated/started will heat up with no combustion gases.   I have small chemical something warmers for the army, that with water added produce heat for a limited number of hours.  Some are reactivable by heating in an oven, allowing reuse.

Something in that line of products, instead of :

Thank you.

My searches did not show results for space/room heating.  Medical and food warming pads are far from room heating capabilities.

Part of that is simply a matter of scale, and it was unclear that this is what you were looking for.

You can heat up a space via many methods and ways; but the object wanting to get warm must absorb part of it.  Not efficient.  That is why very warm multiple layers of winter clothing on a persons body is usually the most efficient method of heating.  An extreme example would be heating a living space in dead cold extreme winter while having the people in the room only wearing swim suits.  They may eventually get warm but would have to work at it.  The heavily dressed folks would want to get un dressed.  The bikini girls would want to get dressed.
