Heating Facts

Most people associate Las Vegas with extreme desert heat. What they fail to understand is that deserts rapidly lose heat, resulting in cold winter temperatures. That makes an efficient heating system crucial. A central heating system provides warmth to the whole interior of a building (or portion of a building) from one point to multiple rooms. When combined with other systems in order to control the building climate, the whole system may be an HVAC (heating, ventilation and air conditioning) system.

Central heating differs from local heating in that the heat generation occurs in one place, such as a furnace room in a house or a mechanical room in a large building (though not necessarily at the “central” geometric point). The most common method of heat generation involves the combustion of fossil fuel in a furnace or boiler. The resultant heat then gets distributed: typically by forced-air through ductwork, by water circulating through pipes, or by steam fed through pipes. Increasingly, buildings utilize solar-powered heat sources, in which case the distribution system normally uses water circulation.

In much of the temperate climate zone, as well as desert areas prone to cold winter temperatures like Las Vegas, Henderson, and Boulder City, most new housing has come with central heating. Such areas normally use gas heaters, district heating, or oil-fired system, often using forced-air systems. Steam-heating systems, fired by coal, oil or gas, are also used, primarily for larger buildings. Electrical heating systems occur less commonly and are practical only with low-cost electricity or when ground source heat pumps are used. Considering the combined system of central generating plant and electric resistance heating, the overall efficiency will be less than for direct use of fossil fuel for space heating.

Types of Heating Systems

At Home Air Conditioning and Heating, Inc., we work on various types of heating systems including furnaces, rooftop, heat pumps, and hyrdronics. Not sure which you have? Here’s a quick summary of common heating systems.

Furnaces
Furnaces create heat via combustion. Older units were 40% to 60% efficient. New equipment starts as high as 80% effiency, the optimum being the 95% effecient sealed combustion furnace. Natural gas is the warmest and most inexpensive of all heating sytems.

Heat Pump
Heat pumps move heat energy from one location to another, using a reverse refrigeration cycle. The most efficient heat pumps are as energy efficient as a natural gas furnace. When correctly serviced and maintained, this is the premiere choice of equipment. In mild climates a heat pump can be used to air condition the building during hot weather, and to warm the building using heat extracted from outdoor air in cold weather. Air-source heat pumps are generally uneconomic for outdoor temperatures much below freezing. In colder climates, geothermal heat pumps can be used to extract heat from the ground. For economy, these systems are designed for average low winter temperatures and use supplemental heating for extreme low temperature conditions. The advantage of the heat pump is that it reduces the purchased energy required for building heating; often geothermal source systems also supply domestic hot water. Even in places where fossil fuels provide most electricity, a geothermal system may offset greenhouse gas production since most of the energy furnished for heating is supplied from the environment, with only 15–30% purchased.

Hydronic (Water sourced)
Hydronic systems create heat energy by heating water and transporting it throughout the house. A pump circulates the hot water from your hot-water heater to a hydronic coil connected in parallel with your air conditioning system. Hydronic radiant floor heating systems use a boiler or district heating to heat water and a pump to circulate the hot water in plastic pipes installed in a concrete slab. The pipes, embedded in the floor, carry heated water that conducts warmth to the surface of the floor, where it broadcasts heat energy to the room above. Hydronic heating systems generally consist of a boiler or district heating heat exchanger, hot water circulating pumps, distribution piping, and a fan coil unit or a radiator located in the room or space. Hydronic systems are closed loop: the same fluid is heated and then reheated. Hydronic heating systems are also used with antifreeze solutions in ice and snow melt systems for walkways, parking lots and streets. They are more commonly used in commercial and whole house radiant floor heat projects, whereas electric radiant heat systems are more commonly used in smaller “spot warming” applications.

Rooftop Equipment
Rooftop systems can consist of either a heat pump or a cooling system using gas heat. Ducted from your roof to your house, this system needs to be cleaned and serviced on a more regular basis than most equipment. If installed correctly, it can be the quietest and most efficient.

No matter which type of system you have, trust the experts at Home Air Conditioning and Heating, Inc. to take great care of you!
