In a conventional forced-air system, one thermostat controls the temperature of the entire home. If you want to heat ANY room, in other words, you must heat EVERY room. Next-generation options like radiant heating enable you to reject the all-or-nothing approach and all the energy that it wastes. Instead, the technology lends itself with surpassing ease to a zoned setup, in which you can target different temperatures to different parts of the house. That way, you can turn up the heat in the space you're in, while turning it down everywhere else. Not only does zoning save you significant sums of money, but it also saves you from the stress of family infighting over the thermostat setting. At last, different household members with different temperature preferences can all be comfortable at the same time.
