Gas and electricity power today's modern heating systems, as they force air through duct channels and vents throughout the house. Central heating is only one component of the overall HVAC system, and it works together with the cooling system.
All electric HVAC systems use electricity for both heating and cooling. An electric furnace and outdoor condenser are used in an all-electric heating system. A split system, fired by either gas or oil, is also used in many homes today.
These systems extract warm air from inside the house in the summer and transfer it outside. In the winter, the reverse takes place, as the air is heated instead of cooled. Duct systems distribute conditioned air and produce a set path of air circulation throughout the house.
Ducted Systems For Heating & Cooling
Ducted systems provide heating and cooling throughout the entire house. Heated or cooled air is pushed through ductwork and vents in the ceiling, behind walls or on the floor.
Gas-ducted systems are very similar to gas and electric AC systems. They are a cost-effective way to provide heat, especially in freezing climates.
When both heating and cooling are required, you want to receive the benefits of both gas-ducted heating and cooling.
Gas vs. Electric HVAC Systems
Many homes located in colder climates rely on the furnace for warm comfort indoors. However, if you live in a warmer climate or in an area where gas is restricted, electric heat is the other choice.
Low maintenance and a longer lifespan mean you don't have to worry about your heating system. Electric heat pumps for energy efficiency with an electricity-powered system should be considered.
These systems do double duty as an air conditioner in the summer and for heating in the winter. Gas heating is less expensive, and it also heats up the house faster than electric heat. However, gas furnaces themselves are more expensive than electric ones, and installation is more involved due to venting requirements.
Energy Efficiency of Gas vs. Electric HVAC Systems
Gas and electricity costs will vary by region. In general, gas furnaces cost less to operate than electric systems, while electric heating often costs more to run.
When you compare a gas furnace to electric heating, also take note of the upfront and running costs of each, and how each system affects the environment.
The Environmental Impact
According to the U.S. Environmental Protection Agency (EPA), electricity is generated using methods that are only thirty percent efficient.
Natural gas releases greenhouse gas emissions and other contaminants, but it burns cleaner than coal, thereby contributing less harm to the ecosystem.
