If you have a furnace in your home that is 20 years old or older, then you may be looking for a replacement. And, while the basic function of your furnace has not changed in a number of years, there are a whole lot of newer features that may come with your new heater. Keep reading to learn about a few of them, what they do, and why you may want them.
If you have a forced-air heating unit, then your furnace has a blower. The blower is essentially a fan attached to a motor that forces heated air up into your ducts and through your vents. You may be used to your blower simply turning on and off with heat moving quickly through your vents during the heating cycle. While this may be effective, you may notice large temperature swings. This is due to the blower either running or not.
Newer furnaces have variable-speed blowers that can run at different speeds depending on the call for heat. This allows for a consistent heating ability with more comfortable temperatures in the home and a reduction in hot and cold swings.
Variable speed blowers are also quieter and far more efficient than single-speed devices. This is due to the way that the motor ramps up to full speed instead of running full blast from an off position. This means a reduction in your heating costs and a more pleasant atmosphere without the constant noise of the heater fan going full force.
If you are used to the older pilot light system where a small flame remains alight at all times, then you may be surprised to learn that the pilot light is mostly a thing of the past. Now, heating units use electronic ignitions where a small spark is created to light the fuel instead of a flame. Some units even use something called a hot surface ignition that does not even require a spark. This type of ignition is not only convenient but also safer and more energy-efficient.
The electric ignition reduces fuel usage since there is no flame to keep alight. And, this also means that you do not have to worry about whether the pilot light has gone out, preventing the furnace from lighting.
Keep in mind that spark ignitors do need to be replaced on occasion. They are not completely fail-proof, but they are plugged into an adapter, so they are quite easy to replace if there is a need.
