Why Are Condensing Boilers the Best Option?
Best Condenser BoilerWhy Are Condensing Boilers the Best Option?
Condensing boilers are the most efficient boiler on the market today. The reason they are so efficient is that they have a very clever extra component within them. They have a second heat exchanger which takes the hot exhaust fumes (steam) and turn that back into reusable energy rather than let it go to waste. Older boilers would lose a lot of heat through the flu, but with condensing boilers they catch that heat loss and recycle it. It makes perfect sense really. Plus there is the added bonus that you will save money because you will not be burning as much fuel. With fuel cost constantly rising lately this is on everyone’s mind.
The actual term condensing means to turn gas or vapour into a liquid. This is exactly what a condensing boiler does; it turns latent heat (steam) back into a liquid gas form which can then be re used. These types of boilers are highly efficient and are pretty much the only type of boiler you can buy today.
To find out how efficient a boiler is there is a boiler rating which was set up by the UK government. It is known as SEDBUK which stands for Seasonal Efficiency of a Domestic Boiler in the UK. This system was set up by the government and had the full co-operation of boiler manufactures including Worcester. The rating shows the average efficiency of the boiler in normal homes. It is based on what a standard home would use, the climate and pattern of usage. Each boiler gets scored on its performance with ‘A’ rated boilers being the most efficient and G being the least.
Finding an ‘A’ rated boiler is easy, most of the main boiler and central heating installers will only use ‘A ‘ rated condensing boilers. You can now go online and look at many companies and see the actual boilers they sell. If they don’t go into a great amount of detail about the boiler you could take a note of the make and model and then use a search engine to find a site which does give you a complete guide on that particular boiler.
Getting one of these modern efficient boilers installed should only be carried out by experienced and qualified engineers. If you want your boiler to use gas which is the most popular fuel in the UK then the engineer needs to be on the Gas Safe Register. A legitimate company will have a Gas Safe Id number which you can check against the Gas Safe websites. This is to ensure they are legally allowed and qualified to work with Gas. Having a new boiler installed by someone who isn’t on the Gas Safe Register is seriously dangerous. Poorly fitted boilers can cause gas leaks or explosions which can kill. So for the safety of your home and family never allow anyone to do gas works unless they are on this register.

Condensing boilers are specially designed to ensure greater efficiency when compared with normal boilers. While the efficiency of boilers can be normal about 75%, with a condensing boiler can reach more than 87%. Normal in an incinerator, the exhaust gas has a lot of wasted heat to 180 degrees C, the special design of this extract, and the gas and leave a cooler temperature of 55 ° C.
Most boilers are only a matter of the combustion chamberreached from the heat exchanger through the vapors that pass. Finally the fire escape at the top of the heating system. Because of the room, the heat is not enough. The gases expelled to store a large amount of useful heat that is lost time. Consequently, the efficiency of these boilers to remain at the bottom.
On the other hand, a condensing boiler has two bedrooms. Heat increases primarily through primaryexchanger. At the top, the vapors are diverted through a secondary heat exchanger. It extracts more heat from the combustion gases and reduces its temperature about 55 ° C.
This reduction in temperature causes the condensation of water vapor. As the vapor condenses, water droplets form. These come in gravity flow and collect at the bottom of the exhaust manifold. The remaining gases are expelled from the top using suction.
Condensedunit must be paid in the drainage of waste. Pipe flow and return must be kept at a temperature below 55 ° C, so that the device works. This allows the heat of combustion gases is transferred to the water.
The extraction of energy from the combustion products takes place in two phases. In the first stage, heat is extracted as heat sensitive. It is the energy that is transferred from a hot to a cold. This occurs in the first roundexchanger of the heating system. In the second phase, the latent heat of evaporation is used.
Is the thermal energy that went into the water turns to steam when boiled in steam heating system in the form, and is released when the steam condenses back. What happens in the second heat exchanger. After the transfer of latent heat, the steam condenses into water. And 'this double transfer of thermal energy, resulting in condensing boiler efficiency during theregularly.
