What is the difference between a natural gas conventional furnace, a mid efficient furnace and, a high efficient furnace?
The difference is in the efficiency (a measure of how much of the heat generated actually stays in your house). A mid efficiency natural gas furnace has an efficiency of 80 to 89 per cent. A high efficiency natural gas furnace has an efficiency of 90 per cent or higher. By contrast, older conventional natural gas furnaces have an efficiency rating of about 60 per cent, leading to energy losses of up to 40 per cent. This means that for every dollar you spend on heating your home, only 60 cents are actually working for you, while the remaining 40 cents are lost in equipment inefficiencies. Talk to a qualified contractor for more information.
