Residential Forced Air Heating System Fuel Economizer
The unit is a microprocessor-controlled, fuel-saving device for residential forced-air heating systems. The unit reduces: fuel consumption, wear and tear on parts, flue emissions and electrical usage, when installed on any new or existing forced air furnace.
EnerGo Forced-Air Heating
How Your Furnace Works Without EnerGo
If you set your thermostat to 70 degrees and the temperature in the house is less than 70 degrees, the thermostat sends a signal to the furnace to turn on the burner and blower. The burner heats up a heat exchanger and the air passing thru the heat exchanger gets warmed up to a maximum temp (i.e. 155) and blows thru the house.
Why Your System Is Inefficient
At a certain point the heat exchanger and therefore the air being blown as well, reach a maximum temperature and cannot get any hotter. The burner is still running but in reality is not adding any heat and is therefore wasting a lot of fuel. Until the desired temperature is reached in the house and the thermostat sends the signal for the burner and blower to shut down, the burner will continuously run although it is not going to increase the air temperature anymore.
EnerGo Solution
When the temperature in the house is below the setting on the thermostat, the thermostat will still send a signal to the furnace to turn the burner and blower on. However, once the maximum temperature is reached, EnerGo will shut the burner off. The blower will still continue to blow the hot air throughout the house, achieving the desired temperature in the same amount of time. The EnerGo will measure the rate of temperature change in the air being blown to determine when to turn the burner back on to get the heat exchanger back to its maximum temperature and then will shut the burner again. Therefore, in a given 10 minute period, EnerGo may reduce the burner run time 2-3 minutes, thereby saving a lot of energy consumption.
