Introduction to Zone Heat
Why zone heat?
When designing a home heat system, there are generally two types of heaters that are used. The first is a furnace, which is designed to heat a building or portion of a building. Furnaces generally are placed in basements and crawl-spaces and duct the heated air or water into the areas to be heated. The purpose of a furnace is to provide heat to keep a home or structure at a specified temperature through the use of a thermostat. One method to decrease the costs of seasonal heating while maintaining occupant comfort is to use the furnace to maintain a minimum level of comfort for the whole structure and then use zone or room heaters to maintain a more comfortable temperature in the room or rooms most often occupied.
An example of this setup would be an oil-burning forced air furnace that heats the majority of a home to perhaps 52 degrees, which protects the structure and amenities from freezing damage, but is too cold for most peoples comfort. The occupant then warms the kitchen and living room to 65 degrees using a wall-mounted gas heater and a gas-powered stove. Zone heating makes sense in this case because heating the whole structure to 65 degrees with the oil-burning furnace would cost far more than using two small room heaters.
Zone heaters increase occupant comfort in the area immediately around their installation. The majority of room heaters are designed to heat using two methods: direct infrared radiation and air convection. Infrared heating is accomplished through the use of ceramic 'glass' or screens which allow the flames to directly radiate heat onto surfaces exposed to the light of the flame. Convection heating is the type of heating that a forcded air furnace does, where the heat of combustion heats an exchanger which heats the air and then the warm air is blown into the areas to heat.
Infrared radiant heat is much like the direct warmth felt on a cool day when the sun is shining directly onto a surface or your skin. The surface itself is heated directly, while the air surrounding the object is heated by the warm surfaces heating the surrounding air. Surfaces in direct line-of-sight from the infrared source are heated. This type of heat can increase occupant comfort without having to first heat the air mass of a room. Eventually, through surface warming, the infrared heat will heat the air of the room too. There are certain heaters that are designed to produce a greater amount of infrared heat. This type of heater can be most appropriate for workshops, basements, attics or other storage areas that will be occupied for a short period of time in most cases. The heater can be turned on briefly to immediately make the area feel warmer or set with a thermostat for heating up the entire air mass.
Convection heaters generally have a blower or a fan that circulates the heated air from around the heater out into the room. Most stoves generate the bulk of their heat this way. Since zone heaters are not generally allowed to be connected directly with forced air systems, the heat tends to stay inside of a room or area immediately around the heater. This air can be circulated to some degree using the forced air return system in a 'fan only' mode, but generally is most efficient in heating the area or zone near the stove.
In zone heating, there are a few choices when it comes to fuels. Each fuel has qualities that may make it more or less suitable for a given application. The choice of fuel will affect the cost and overall convenience of a given zone heat system. Fuels are divided into solid fuels and gas or liquid fuels. Solid fuels generally require the most operator time and effort. Wood (or biomass) and coal are the most common solid fuels used in the United States. Gas (both natural/town gas and liquefied petrolium gas), kerosene and fuel oil are the most common liquid fuels.
