Difference Between Combination And Condensing Grand Prairie Boilers

By Gregory Gray


Many people are confused about combination boilers, condensing boilers and condensing combination heaters. Many think that both of the heaters are the same, but there is a huge difference between them. Today I am going to give the complete details of combination heaters, condensing boilers and condensing combination Grand Prairie Boilers and differentiate them.

The old type heaters would normally work with a hot water storage tank located in the airing cupboard, this tank stores your hot water so you would have a supply of hot water as and when you needed it, as the water was used the boiler would start to reheat the water. The problem with the old type heaters is they are very expensive to use, somewhere around 40% of the running costs is wasted through the boiler flue. That's a lot of money to throw down the drain.

The high efficiency or condensing boilers as they are known while running produce condense, this is an acidic water, because it is acidic, it can start to corrode the flue-pipe, and should this happen the flue will start to leak products of combustion (carbon monoxide), which as we all know can be very dangerous to life, this is one of the most important parts of the service.

All condensing boilers have a condense trap built in, this needs to be cleaned out and checked for leakage it's also part of the boilers flue system. When the boiler is running the water it produces cleans the combustion chamber of any residue and this ends up in the trap. With many boilers of today they work under high pressure and have an expansion vessel connected to the pipe work, this can be either internally or externally.

The combination boiler supplies both hot water and heating without the need of having any storage tanks. The problem though is many people don't understand how they work. Let me explain, the combination boiler can only supply so much hot water at a time, so if you were in the shower and someone opens the hot tap in the kitchen, you may notice the shower turns cold.

Condensing heaters: These are the most energy efficient heaters presently available in the market. These types of heaters are 93% energy efficient saving your energy bills and saving the environment. They use the similar technology used in conventional heaters, but the main different is that, condensing heaters reduces the heat from the flue gases from approximately 300 degrees to 50 degrees, condensing out the vapor produced by combustion of the fuels. In condensing heaters the heat exchanger is bit larger or there may be a second heat exchanger which hunts down the heat which is not recovered by the main heat exchanger.

By making use the second heat converter they become more energy conserving than mainstream heaters. Generally condensing is 93 percent energy efficient where as conventional heaters are only 78 percent. But the main disadvantage of condensing heaters over conventional heaters is the price. They are about 300 to 400 pounds more expensive than the conventional heaters.

With an annual boiler service these are just a few of the checks that need to be carried out, and because many boilers now come with long warranties, to keep the boiler warranty valid you must have an annual boiler service. Once the service has been carried out, then the engineer needs to date and sign the warranty booklet to keep the warranty valid.
