STEP 1 Safety first! You’ll need to set up a heatproof platform in the room you intend to heat. A 2-foot (0.6-m) square of bricks on the floor will work fine. Then get some rocks or a few bricks from a dry location.
STEP 2 Fire up the grill or build a fire outside, and throw the rocks or bricks in the fire to heat them up. Heat for about 45 minutes and then scoop them out with a shovel. Get all the coals and sparks off of the bricks or rocks before continuing.
STEP 3 Drop the bricks into a stainless-steel cooking pot. Other types of pots can be damaged by the heat, and galvanized buckets can release toxic vapors with heat exposure. Stick with the steel pot.
STEP 4 Carefully bring the hot rocks or bricks inside and set the pot on your fireproof, heatproof platform. Repeat as needed every few hours. Now you’re ready for that cold weather power failure, and a variety of other scenarios that would leave you without heat.
