Heat Stage Options in a Home Furnace
One of the first things to consider is how many stages of heat a furnace offers. Each accomplishes a different objective. Choosing between a single or one stage furnace and a two-stage furnace can depend on the size of your home and the type of efficiency you are looking for.
Single-Stage Home Furnaces
When the thermostat detects the home temperature has dropped below the designated value, it turns the furnace on. With a single-stage home furnace, it goes directly to 100% heating capacity to heat the home, then shuts off once the thermostat senses the pre-set temperature has been reached. This is the typical operation of a single-stage furnace.
Two-Stage Home Furnaces
A two-stage furnace differs from a single-stage in key regard. When the thermostat detects the temperature drop below the pre-set value, it turns the home furnace on, but only at 60% of full heating capacity. This is the first stage of a two-stage furnace. If, after 10 minutes, the thermostat reads a temperature below that of the pre-set value, the second-stage of the home furnace activates which ramps the heating capacity up to 100%. It will stay at 100% until the thermostat measures the home temperature rise above the pre-set value.
Modulating Gas Value Home Furnace
Some manufacturers offer a modulating gas value technology that offers up to 60 stages of heat. It works in the same way as a two-stage home furnace, except the initial heat capacity can start as low as 40%. The furnace can then work its way all the way to 100% as needed.
Benefits of a Multiple-Stage Home Furnace
Having a multiple-stage home furnace has several advantages:
- Quieter operation: home furnaces are quieter when running at lower capacities
- Better home comfort: a slower pace of heat in the home provides more gradual temperature changes, instead of rapid temperature changes a single-stage home furnace provide
- No furnace short cycling: short cycling is when a furnace turns on for a few minutes then quickly shuts down, a condition that can can extra wear and tear on a home furnace
- Longer life expectancy: multi-stage furnaces utilize the furnace at lower levels when possible helping lengthen the service life
