Glass furnaces – for domestic heating needs
Glass furnaces have been an integral part of homes ever since they were invented. In a world that is seeing extreme climatic conditions, a gas furnace is inevitable. The efficiency of these furnaces is measured by the Annual Fuel Utilization Efficiency (AFUE), it measures the thermal efficiency of furnaces and the efficiency is calculated in percentage. A high AFUE rating means that the furnace is very efficient, the lower the rating drops the efficiency is also considered low. Since the appliance looks like a large box, it is usually concealed within units that are meant for these appliances.
How gas furnaces work:
A gas furnace takes in cold air, conditions and cleans the air using an air filter and then heats this air with the help of a heat exchanger made of stainless steel. This warm air is then distributed through the home’s ductwork with a blower motor. Once the heated air enters the rooms through the duct, the air eventually cools down and re-enters the furnaces through the same channels with the assistance of the return air grills.
Furnaces that can be found in the market today are engineered precisely to deliver optimum heating while remaining energy efficient, advanced technology is used to ensure that the service offered by the furnace is impeccable and that they are also affordable for people.
What to keep in mind while buying gas furnaces:
There are various types of furnaces in the market and it is quite easy to get confused about which one to buy, here are a few things to keep in mind while buying and installing a furnace:
- Always buy branded furnaces that come with a warranty and manufacturer assurance
- One must first check if the blower fan operates efficiently before buying the furnace
- Attention should also be paid to the design of the venting system
- Air ducts must be sealed appropriately to increase efficiency
- One must always check for the AFUE rating before buying a furnace
- The furnaces purchased should adhere to federal standards of energy efficiency
- The type of furnace purchased should be suitable for the size and build of the home
Maintenance of gas furnaces:
Unless furnaces are maintained properly their efficiency levels will not remain the same. Furnaces must be cleaned at-least once a month and serviced by a professional either annually or bi-annually for better efficiency. The return grills and duct area must be dusted every now and then to ensure there are no barriers to the smooth flow of air in and out of the duct.
One may buy a conventional warm air furnace, induced draft furnace or a condensing furnace depending on the needs of the household as each of these types of gas furnaces offer varying levels of efficiency. The right furnaces can provide comfort, optimum temperature indoors and prove to be highly efficient, their efficiency will also determine the overall energy efficiency rating of homes that have them installed.
