Gas Home Furnace

A gas home furnace is an appliance that is used in a house to provide you with heat, with the help of some sort of fluid movement, and it can be either steam, air or it can also be hot water. Usually, furnaces in the US are based on gas as their main fuel. You will also find LPG, coal, fuel oil or wood, among the other possible fuels for a furnace. In places where electricity is very cheap, you will also notice furnaces that use it as the main source of power.

When it comes to combustion based furnaces, you know they need to vent towards the outside, and usually that is done with the help of a chimney. The problem with a chimney is that it expels heat as well, not just exhaust. If the furnace is modern, it can get to an efficiency of up to 98%, while operating without the help of a chimney. This happens because it uses a small tube to vent the heat and waste gas. This tube will be usually place either on the roof or the side of the house.

Usually, home furnaces are either of the non-condensing or the condensing type, based on their heat extraction efficiency. When a furnace has efficiency bigger than 89%, get so much heat that the water vapors will condense in the exhaust, so they are considered condensing furnaces. If you have a furnace that is of the condensing type, you will get heating savings of up to 35%, when replacing an older type of furnace.

The origin of the furnace name comes with a Latin word called fornax, which meant oven. The oldest one found was at Balakot and it’s thought to come from a period that was in 2500 BC. They used that furnace to create ceramic objects.
