The Rumford Fireplace

January 23, 2019 | Chimney Basics

The Rumford Fireplace – An Early Modern Fireplace Design   The Rumford Fireplace, invented in the late 18th century, was one of the most important innovations in fireplace technology at the time. Learn more about its history and how it works now!   The History Of The Rumford Fireplace   The Rumford Fireplace was first prototyped by Sir Benjamin Thompson, also known as the Count of Rumford. He was an American-born British physicist, who was very interested in studying heat and convection.   He created this fireplace in the 1790s, by creating a shallow, small fireplace with widely-angled sides to reflect heat into the room more efficiently. The fireplace quickly became a sensation in London and spread throughout the world.   How It Works   Beyond its angled sides, the principal innovation of the Rumford Fireplace was the idea of restricting the chimney opening using bricks. This, in turn, resulted … Continued

A brief history of the fireplace!

January 23, 2019 | Chimney Basics

Have you ever wondered how the modern fireplace came to be? In this article, we’ll take a brief look at the history and development of the fireplace. Prehistoric Times – Ancient Cave Fires And In-Dwelling Fires The first “fireplaces” weren’t fireplaces at all! Early humans first started making fires in holes in the ground, and in caves, where they could enjoy the warmth and shelter from the elements. As we began to build more permanent dwellings, humans started building fire pits inside their huts, and in tents and other movable homes. Most huts had holes for ventilation, but there was still a high risk of carbon monoxide poisoning and smoke building up inside. Still, fires built in huts in this way were very popular, and we continued to build indoor fire pits like this until the Middle Ages. The Middle Ages – The Hearth And The Hall The hearth was … Continued

All About Firewood!

January 23, 2019 | Chimney Basics

Ahh, nothing quite like the crackle of a fireplace, or the warm and welcoming heat of a wood-burning stove or furnace. And, just like any other appliance, the type of fuel you choose for your wood-burning appliances matters. In this article, we’ll discuss the basics about choosing the proper type of firewood, storing it, burning it effectively, and more. Let’s get started. Choose Seasoned, Dry Firewood For Maximum Heat And Efficiency  First things first, you’ll want to make sure that you burn seasoned, dry firewood in your furnace, stove, or fireplace. Seasoned wood will create heat more efficiently, and create less creosote, which helps keep your flue safe and clear. All firewood contains water, but fresh wood contains up to 45% water. While it may burn, a lot of energy will be used to vaporize that water and dry the wood before it burns, which means less heat in your … Continued

A roofing disaster

January 10, 2019 | A Day in the Life

On one of my inspections yesterday, I encountered an absolute mess of a job performed by a roofer I will not mention. A new roof was installed a few months ago without replacing the chimney step and counter flashing and now the deteriorated flashing has started to allow water intrusion into the home. The roofer was called out again and this was the initial fix: 🤦‍♂️ Not only did they not replace the flashing (again), they covered the cracks on the crown with sealant that I now have to remove before correctly repairing the crown. All of this could have been prevented if the job was done correctly in the first place and it would have also prevented the water damage that is now inside of the home.

Why are chimney sweeps considered lucky?

January 6, 2019 | A Day in the Life

Several theories exist but certainly no one knows for sure. One of the most popular theories is that King William of Great Britain was saved by a chimney sweep after almost being killed by a runaway horse carriage. Another theory is that a chimney sweep was working one day (timeframe unknown) and almost fell from a roof. While hanging from a gutter, about to fall to his doom, a woman inside of the house saw him and pulled him inside saving his life. After the near death experience, the two fell instantly in love and were married. It is still a popular tradition in Great Brittian for a chimney sweep to attend a couples wedding as a sign of good luck!

Radiant heat and the impact on combustibles

January 6, 2019 | Chimney Basics

So you may have heard me talk about clearances to combustibles once or twice before but here is a quick example of what the heat does to combustibles and how it can start a fire. As heat is absorbed by a combustible, in the form of radiant heat, it slowly breaks down the ignition temperature that is needed to ignite the combustible. the process is called pyrolysis which is the thermal decomposition of a material through elevated heat. Ignition temperature of wood can drop to as low as 300 degrees after long-term exposure to heat! One very key thing to also remember with ignition of the combustible is that it will ignite without any direct contact with flame. Here is a example in fast forward: 1. Initial break down of wood from heat As you can see, the Wood is not touching any flame throughout the timeframe. 2. Ignition temperature … Continued

Rusted chase covers = Water leak

December 29, 2018 | Chimney Basics

Here is a good example of how water enters your chimney from a rusted chase cover. Here is the first picture showing what it looks like from the top: Now lets take a look around the center flue termination from the bottom side: Not looking good! Now a even closer look. Notice the light shining through the small pin holes: When you see a rusted chase cover on your roof or signs of rust staining the side of the chimney, it may be time to replace your chase cover to prevent water intrusion.

Fire Extinguishers

December 29, 2018 | Chimney Basics

Let me start off by saying everyone should have multiple ABC rated fire extinguishers throughout their home for safety. A fire extinguisher is something that you hopefully never have to use, but can save your home or life in the event of a fire. What does the A B C stand for? A – Trash, Wood, and Paper Monoammonium phosphate is the main ingredient in the fire extinguisher that will help smother this type of fire. B – Flammable Liquids Monoammonium phosphate and sodium bicarbonate work together to help extinguish a fire involving flammable liquids. C – Electrical Equipment Again, both Monoammonium phosphate and sodium bicarbonate work together to help extinguish a fire involving electrical components. – How to use a fire extinguisher – The recommended method is the P.A.S.S. technique. Below is the step by step technique directly from OSHA: PULL… Pull the pin. This will also break the tamper seal. … Continued
