Energy efficient condensing boilers are one of the most effective ways to save on home energy costs . While the units have been around for the last quarter century, some people have found the initial cost to be prohibitive. However, the good news is that the costs have come down a good bit in the last few years as manufacturing methods have made it less expensive to produce them.
Hopefully, this will mean that consumers in the United Kingdom and the United States that rely on a traditional central heating boiler as a heat source will soon discover the condensing boiler and its excellent energy saving properties.
How do Condensing Boilers Work
The basic process of how condensing boilers works is something like this.
The boiler will extract the heat from the type of fuel it is burning, which results in cooling the products of combustion. Often this would result in the loss of this portion of heat right out the flue.
The cooling of the combustion products results in the water vapor converting back into droplets of liquid, which are moved along with the use of a fan. A larger and more efficient heat exchanger is used with the condensing boiler in order to harness what is called the latent energy of the droplets. Being able to harness what otherwise would be lost energy allows condensing boilers to generate in the range of 15% more efficiency than a traditional boiler.
Increased efficiency translates into the creation of less carbon dioxide, since less fuel is being used to supply the same amount of energy. Less fuel usage of course means fewer costs to operate the condensing boiler versus what is needed to operate a traditional boiler.
Condensing Boilers Efficiency
Condensing boilers present energy savings on both the back end and the front end. For example, a basic principle of the condensing boiler is the need to consume less fuel in order to produce the same amount of energy. If you are using electricity or gas as your fuel source, then the installation of a condensing boiler will translate into a noticeable decline in overall energy usage needed as fuel for your boiler. By creating less of a drain on national energy resources, you in effect are saving a significant amount of energy over the course of a twelve-month period.
On the back end of the process, condensing boilers are saving energy that normally would be going right up the flue and be lost forever. By harnessing the power of the liquid that is created when the water vapor is cooled, the condensing boiler makes a much more efficient use of its resources and supplies the home or business with all the power required to operate. This increased efficiency in using everything created in the process is another way that condensing boilers help to maximize energy conservation.
How Long do Condensing Boilers Last
There are a couple of indirect ways that condensing boilers save energy. Both of them involve the actual life of the unit itself. Because a condensing boiler tends to require less maintenance than its traditional counterpart, less energy is expended in keeping the boiler running properly. In addition, a condensing boiler will simply last longer than most conventional boilers. That longer life eliminates the need to for the production of as many units, which converts to less energy used in the production process over the years.
Condensing boilers are currently more popular in the UK, although they are beginning to make some headway in the US as well. As more people benefit from the increased energy efficiency of condensing boilers, you can anticipate more interest in the units, especially among people who are seeking to conserve energy and still maintain a comfortable lifestyle.
