Its optimal energy efficiency level is just one of the numerous features it has. Gas-powered crawl space heater provides an efficient heating solution for hard-to-heat spaces, but it also offers unique benefits like energy savings and improved indoor air quality. There are different things to look out for when shopping for a crawl space heater. If there is any way for air to rise from the crawl space into your home – which there surely is – the cold air entering from outside is warmed in the crawl space, and since heat rises, this warmed air rises through the floor into your home, drawing in more cold air from both crawl space vents. A crawl space heater may seem like the right solution to cold floors above a crawl space in winter.
