Difference Between Combination And Condensing Grand Prairie Boilers

By Gregory Gray


The annual boiler service is a very important job that is best done in the warmer months of the year, but did you know around 90% of us never have the boiler serviced. The boiler for some reason seems to get forgotten until something happens, you go to have a shower and find you have no hot water. Then you start to panic trying to find someone to repair the Grand Prairie Boilers.

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 good thing now though is that all new heaters are highly efficient condensing heaters and they should save you somewhere around 35% on your fuels bills, that's a big saving, compared to the old heaters. So when it comes to replacing your boiler you will start to save on the running costs. Today there are many types of heaters to choose from, you have heat only heaters, which are open vented, where you still keep the small tank in the loft, the water is still heated via a storage tank.

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.

Part of the annual boiler service is to check the boiler combustion rate. This is to make sure the boiler is burning gas as it was designed for, this is carried out using a flue gas analyzer which is inserted into the flue-pipe and a reading is taken, if the readings are within the heaters recommendations then no further action is required, but if the readings are out of the recommendations then further investigations are needed to find the problem.

With the internet available to most of us now, you can do a search for a local company on replacing you boiler, you should find details of some local companies. Make sure you search for a company that is gas safe registered.
