If you want to ensure that your property is as efficient as possible in terms of its energy use then you will need to comprehend the basic principles behind heat transfer engineering as worked on by Pratt Whitney. For most of us the cost of heating our home makes up the greatest part of our annual utility bills. Without adequate insulation then the associated cost can be very high. As the world is still struggling to come out of recession we should do as much as we can to ensure we are not wasting energy and unnecessarily paying a high electricity bill.
You are probably aware that heat will transfer from a hot surface to a cold surface. This is easily apparent. For example the walls and furnishings next to your radiators or heaters will get warmer faster than those objects further away. The basic principle is known as radiation.
If the heat transfers through an object then the process at work is known as conduction. A good example is when we place an iron poker in an open fire; the heat transfers through the metal to the handle. This is an essential principle to understand when we come to insulate our properties. Without choosing the right material you’ll find that heat is lost more rapidly through the structure of the building.
The third form of heat transfer is known as convection. This occurs when the energy is dissipated into water or air. A convection current is often thought of as a moving body. For example the global weather systems operate through convection. Also, a heating system that involves a fan or blower could be described as using convection. If you have draughts in your property then heat can be lost through convection.
Now we understand a little about how heat is transferred, but how can we take this knowledge and implement it into our homes? Well, we need to understand that heat transfer engineering have dramatically advanced over the last ten years. By choosing the right building materials and insulation you can make changes so that you bring down the amount of heat transferred both inwards and out.
When you check out various materials as insulation look for the “R” rating. This will help you to understand how suitable the product is. The higher the “R” rating the more efficient it will be at stopping the transfer of heat.
Remember that it is not just through your roof that energy can dissipate. Your walls, windows, doors, in fact any physical structure needs to incorporate a design that will reduce the flow of heat. You need to think about the complete property and not just specific parts of the structure.
The technology and understanding relating to fluid heat transfer have dramatically advanced over the last ten years due in part to the work by Pratt and Whitney. Now you can ensure that your home is kept at the optimum temperature at any time of the year. As a greater emphasis is placed on energy efficient homes, so is the availability of the right products. Alongside the financial savings, by correctly insulating your home you will also be reducing your carbon footprint.
