A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Shrawardine Shropshire SY4 and throughout the United Kingdom. It heats water which flows through pipes or a radiator, and it is used for hot water in the home as well as for a central heating system. It is also used for radiant floor heating systems. An annual boiler inspection and maintenance check by a registered “Gas Safe” gas boiler service heating engineer is essential for safety and comply with UK Law.
The Engineer will make sure that the heating system is installed according to regulations during the annual central heating and boiler inspection, that it is safe and it is working efficiently according to the manufacturers’ instructions. If this is done properly every year, gas boiler breakdowns and the resulting emergency repair work can often be avoided.
Shrawardine Shropshire SY4 Super Low Energy Combi Boiler Inspection – Several Things You Need to Take Note Of
The main theory of what a conventional non condensing boiler does is pretty simple. A boiler works by igniting a combustible fuel source (oil, natural gas, or LP gas), with an appropriate air mixture. The heat from the flame and hot combustion gases pass through a heat exchanger within the boiler, where water is heated and then circulated through radiators, under floor radiant tubing, and hot water cylinders throughout the house. The flue gases then escape through the chimney or venting system. A decent amount of heat is wasted with this type of boiler, where the heated gases are just directly vented out. These types of boilers have a lower efficiency rating; no higher than 75%. An efficiency rating is basically a gauge of how much energy the boiler transfers from fuel used to how much heat is supplied to the system.
Condensing boilers work a bit differently. They essentially have some of the same components non condensing boilers do, except for a second heat exchanger. One of the gases produced in the combustion of fuel is water vapour.Where the hot flue gases just got vented out in a traditional boiler; condensing boilers condense these vapours around a second heat exchanger before venting. By the time the gases are ready to be vented out they are much cooler, around 60 degrees Celsius. As a result the vent pipe used in installation can be made of PVC.
With these systems some of the internal components have to be made of more durable material, because the condensed water tends to be acidic with a 3-5 pH. This results in the cost of the condensing boiler being higher than average. The secondary heat exchanger is where the system return enters first. So by the time the water enters the primary heat exchanger it is already been preheated, allowing the boiler to work more efficiently. The efficiency rating from condensing boilers range from between 80% to 98%.
Combi boiler / Combination boiler
Combi boiler / Combination boiler is an excellent choice for homes with limited space. Combi boiler / Combination boiler is a domestic water heater and a central heating system combined into one unit. They have a heating coil inside of them, and function like an unlimited on-demand water heater. Combi boilers don't have cylinders or external holding tanks like traditional systems do, so they can be installed in areas where a typical system would never work.
Condensing Boiler Pros
1 They are fuel economical and have a 15-30% higher efficiency rating than non condensing counterparts
2 Considerable savings on annual energy expenses
3 Most units are very quite ( they make as much noise as a window mounted air conditioner)
4 Many Models could easily fit in a small closet and have combination boiler
5 They are more environmentally friendly with C02 output
Condensing Boiler Cons
1 Initial cost of the unit is more
2 Units need to have the acidic condensate fitted outside or to a waste line
3 The dwelling the boiler is installed in needs to be insulated well, otherwise the heat saved through efficiency will be lost through the walls.
4 Most units need an outdoor weather sensor to operate effectively
High Efficiency Condensing Boilers and Combination Boilers
High efficiency. Space saver. Low costs. These are all important to homeowners who need to heat their home and use hot water. One of the most popular units is the condensing combi boiler that not only provides hot water, but it also reduces the operation and installation costs that other boilers have. This type of boiler works like a central heating boiler and a hot water cylinder at the same time. The name comes from the combination of a condensing boiler and a standard combination boiler. Cold water is instantly heated through a secondary heating circuit, which means that hot water is not stored. Therefore, consumers receive an unlimited supply of hot water for as long as the boiler is firing. Hot water is available within 40 seconds, so a person does not have to run water for a lengthy period of time before it reaches the desired temperature. Consumers save on water and heating costs.
A preferred choice for small homes, condensing combi boilers eliminate the need for some of the requirements that come with more conventional vented heating systems. For example, a separate hot and cold water tank is not required. Also, parts come in a single unit, rather than in separate pieces, which makes the boiler easy to install. By installing a thermostat, water is controlled in the shower, avoiding sudden temperature fluctuation.
The costs for owning one of these units can be somewhat expensive. However, there are some units that qualify for the 2009/2010 tax credit offered by the Federal government. The Embassy Onex is the latest addition to the ambassador line of condensing combi boilers with increased efficiency levels with the indoor/outdoor reset control feature. The Embassy Onex boiler costs approximately $4,275, but qualifies for the $1,500 tax credit. Additional features include a patented ASME heat exchanger; premix burner technology; and, a certified DOE efficiency rating of 93%.
Another condensing combi boiler which qualifies for the tax credit is the Viessmann WB24272, a natural gas unit that costs $5,964.95. The AFUE rating is 95.2%, and the unit comes with a stainless steel plate heat exchanger for instant heating. These boilers do not store water in the cylinder like other boilers, which can waste heat and contribute to adverse environmental conditions.

It is important to maintain boiler systems properly. The best way to do this is to get your boiler serviced frequently. Experts and manufacturers themselves recommend getting your boilers serviced at least once a year, to be on the safe side. Servicing a boiler can make it more efficient and increase its performance. This keeps it in a good and functional condition, making it last longer. Although the sound of servicing your boiler might seem expensive, especially on a yearly basis, the cost will only go up the longer you put it off. In addition to this, it can become harmful and dangerous to all those living in the same house.
A yearly servicing is the recommended frequency; however, there are a few exceptions to this rule that must be taken into account for. Moving into a new house with a boiler already installed needs to be serviced too before it is used. You cannot be sure how old the boiler is, or how long it has been since it was last used or serviced, so it is always best to be safe than sorry. Also, it is recommended to get your boiler serviced if you have been on an extended holiday where no-one has been at home to use the said boiler. A dormant boiler can be filled with anti-freeze that must be drained before use once again. Also, once again, after not being in use for a long time, you cannot be sure the condition of the boiler. There may be clogged or broken parts which to someone who isn't trained in the profession of servicing boilers would be unaware of.
The best time for getting a boiler service done is in between August and October, the last few months of summer. Not only is this after the holiday period, where you might have left the boiler unused for some amount of time, but these months are the in the off-peak season so many service providers would be both available and able to offer you a discount. This means that you can save on money and get a good, professional service from a trained and licensed expert without any hassle. Leaving the service for even a few weeks after this time period will see a rise in the price and the busyness of the workmen as winter comes around and boilers start to break and need fixing.
A good boiler service provider is someone who has a good reputation and is qualified. Finding someone like this isn't hard, as there are many professionals out there, however, it is essential that you make sure that the person you choose to hire is an expert in the boiler servicing field. Checking a person's or a company's licenses can be easily done by logging onto the Gas Safe Register in the United Kingdom and looking up their names. The industry of boiler servicing is very lucrative, with many of your local company's and independent workers offering competitive prices for a variety of different services including boiler servicing. It is important not to get too distracted by the pricing when hiring someone to do the job.
Your boiler system manual is the best place to start when looking for information about its servicing. The manufacturer can also help you by answering any questions you might have that are not mentioned in the manual. Phone numbers and email addresses are usually provided with the manual, but if not, it can be easily found on the internet.
