Single stage heating is common in areas experiencing humid, hot and extreme cold. Because air conditioning will only be necessary during specific months, HVAC systems may have to work harder even when not needed. To solve this issue, a two-stage heating system was born to save energy and money as well as increase efficiency and comfort. Basically, a two-stage heating system utilizes two methods of heat output to provide desirable room temperatures during extreme and mild cold.
How it Works
Unlike the single-stage heating method, two-stage heating operates in two stages that is, high and low. The first heating stages works mostly when temperature requirements are lower. For instance, in the morning or during winter, the systems works at the high stage to provide extra heat. When temperatures are average or the home heat requirements have been attained, the system switches to lower heat mode. At this stage, less energy is consumed as the system is not running at full capacity-about 65%. When shifting between these two temperature outputs, a smooth transition occurs.
Advantages of Two-stage Heating
As opposed to the single or standard heating method, two-stage heating gives continuous comfort by eliminating temperature swings to about 1 degree of the thermostat setting. Two stage heating starts slowly when less heat is needed then shifts smoothly to the next stage when higher heat requirements are required. In essence, the system does not operate at full capacity. Because the system operates at lower speeds, more dust and dirt particles are trapped therefore improving the quality of air. In addition, it operates at lower capacity than normal therefore consuming less energy hence increasing efficiency.
Choosing Two-stage Heating for Your Home
When selecting a furnace for your HVAC system, be sure to consider the amount of time you will spend with your family at home and the amount of money that you are willing to spend on a new heating system. If you want comfort, be sure to spend on a two-stage heating system as you stand to save money.
