Humans have developed a way to survive in all sorts of temperatures. Whether in Antarctica or the Sahara Desert, human beings find ways to not only survive but also to thrive. The Evolution of Furnaces

In today’s time, we have the ability to control our indoor temperature throughout the year. If the weather is cold, then we can crank up the heat, but that hasn’t always been the case. Here’s an overview of the evolution of the furnace.

The Original Furnace

The first known use of furnaces dates back to the time of the ancient Roman Empire. Their process of central heating was to heat up wood under a building. As one could imagine, this was somewhat dangerous.

As time went on, the chimney and the coal-fired furnace were invented. This setup was safer, but the maintenance was tough. These systems required multiple refills of coal throughout the day as well as the constant removal of ashes.

The Modern-Day Furnace

Fast forward to modern times, and you have a large metal device that doesn’t require coal or wood. Many of the furnaces used today operate off gas as fuel. This makes the maintenance much simpler. Still, older model furnaces of modern times don’t work as well as newer ones. The disadvantages of older furnace models include:

• Higher energy bills
• Higher risk of carbon monoxide poisoning
• Fire hazard
• Low efficiency

It’s very important to consider upgrading your furnace if you have an old one. If you can’t seem to get a perfect temperature in your home, then this may be an indication that it’s time for an update. Poor indoor air quality can also be a sign that it’s time to upgrade your heating unit.
