The comfort of home heating is a necessity that most people are dependent on. Installation and repair technicians from home heating and cooling companies say it is important that a homeowner not only understand the basic principles of heat production, but also how heat is transferred in order to choose the proper heating unit to keep a home warm.

How is Heat Produced?

Heat is the product of the reaction between molecules and the byproduct of excited molecules and atoms moving around each other. All physical matter consists of molecules and atoms. When they become excited, the friction created as they bounce and slide off each other creates a thermal reaction or heat. The best heating and cooling consultants say the way to produce heat on demand is to choose a suitable substance and “excite” it or cause a thermal reaction.

How Does Heat Transfer Occur?

Heat transfer is the passage of energy from hot molecules to cooler ones, with a byproduct of heat. This is how molecules acting against each other can eventually heat up the area around them, creating heat over a larger area. This occurs in several different ways which, when applied using heating units installed by home heating and cooling services companies, provide heat for heating purposes in homes and businesses:

  • Convection – Convection heat transfer occurs when thermal energy produced by excited molecules warms non-excited molecules until they begin to experience a thermal reaction. The more molecules warmed by the energy being produced, the greater the overall effect. Boiling water and convection ovens are examples of the convection process, where surrounding molecules eventually help all molecules become excited enough to react.

  • Conduction – When molecules rest against each other, excited molecules give off heat, passing it directly to molecules in contact with them. As this pattern progresses, all molecules heat up and the reaction increases. Heating something directly over a flame is an example of conduction heating.

  • Radiation – Radiant heat is transferred from reactive molecules to surrounding molecules via electromagnetic waves. Heat is transferred without direct contact between molecules, just as the sun heats things that absorbs its rays – like the roof on a house.

Heat Transfer and Home Heating

Understanding the various methods of heat transfer is necessary to also understand the different ways a home can be heated. Forced hot air heaters use conduction heat, blowing air over a heated element, while boiler heaters use a combination of convection and radiant heat. The best home heating and cooling services consultants say that a home can benefit from radiant heat is through the effect of the sun on a dark roof.

It is important to know how to keep a house warm as efficiently as possible. It also helps to understand how home heating units work, so lifestyle habits can be adjusted to allow the heater to be more efficient, the end result being greater comfort for less money.

Any homeowner interested in improving home heating efficiency or upgrading a current heating system should contact the best heating and cooling company in their area for experienced, technical advice. With more efficient products available and a little bit of informed guidance, heating a home is easier than ever. Understanding how heat transfer lets homeowners take an active part in deciding what is best for their home!
