subject: Gas Furnace- Why Are They Useful? [print this page] Come winter, and one appliance that is used excessively is a radiator. Keeping us warm in the confines of our home is what it does. Recent years have seen a surge in the number of gas furnaces being sold.
What makes these so popular?
Not only are they lighter on the pocket, but they are also eco-friendly owing to the natural gas used, helping us do our bit towards the environment.
So how exactly do they work?
A gas furnace behaves exactly opposite to an air conditioner. It sucks in cold air, warms it up nicely, and blows it out through the vents.
But where does the gas figure in this?
The user decides what temperature the room should be warmed to. When the thermostat in the furnace detects that the room is cooler than it should be, it begins its heating process. Fans pull the air into the device, and the stored natural gas flows into the burner. This gas is then ignited with the aid of a spark to heat up the air. When the appropriate temperature is attained, the blower blows out the warm air back into the room, thus completing the cycle. Cold air is continuously fed to the burner until the room is warm enough and the thermostat cuts off. The furnace is fitted with filters to purify the incoming air of dust and other particles.
As mentioned already, these devices are environment friendly and much cleaner compared to their petrol-guzzling counterparts. Also, they do not consume a lot of electricity, unlike electric furnaces. Clean the filters monthly to keep it in a perfect working condition. Keep the motor clean and oil it well. Have a technician check it regularly for pipe leaks, vents and ducts, and circuits. That's all the maintenance it will need!
On the downside, however, natural gas may be a little difficult to get hold of. Also, there is a potential problem of gas leaks, which is easier to detect owing to its distinctive odour.
When you want to shop them, consider factors like the brand of the gas furnace and its quality, and the size of your house. Make sure they tick warranty and after-sales support off your list. They may be a little expensive while buying, but in long term, it is an investment made well. Install them once and do not worry about them for a long, long time to come!
