I use microwave heat pads in my home, as they are usually more convenient for my wife and I. However, since our experiences during the Texas Freeze last year, we purchased some hot water bottles at our new place. Since we have a gas stove, even if the power goes out, we should be able to heat water by lighting the stove with a match and bringing that hot water to our bedroom to be able to stay warm. Plus, we can put a hot water bottle in a pile of hay with our guinea pigs to keep them warm as well. Overall, heat pad and hot water bottle make great every day and emergency use items, even in warmer climates.
