A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Ratlinghope Shropshire SY5 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.
Ratlinghope Shropshire SY5 High Energy Efficiency Combi Boiler Inspection – Several Things You Will Want to Consider
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.
High Efficiency Condensing Boilers and Combination Boilers
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

By opting for a condensing boiler to convert energy of natural gas to heat your home or apartment you are not only helping yourself by saving on heating bills but also make possible environmental well being while helping the whole world.
Wasted energy = wasted money
Whatever the fuel type may be, is said to be efficient about 90% at the lower end and - 98% at the upper. Your 15 year or so old traditional oil fired boiler is at least 12% less efficient than this. Whether it is gas or oil, you can imagine how much fossil fuel the high efficiency boiler would conserve, how much CO2 emission it would curtail and the pile of moolah you would save during the next 30 or 40 year plus life span.
What makes a condensing boiler more efficient?
A traditional gas burning boiler or a condensing boiler of recent vintage technology is not different to any oil burning boiler in basic working mechanism. The extra bit of efficiency in boiler is due to the condensation of water of combustion from steam state to liquid, releasing the latent heat of vaporisation. (Sadly if not for the condensing boiler, this huge percentage of heat energy will be sent up through the chimney as flue gases, without the home owner having a clue to what's happening). Inherently any boiler can achieve fuel efficiencies of 90% upwards easily.
A centralized heating system, incorporating a condenser boiler depends on several other system components. These would include the control system, DHW cylinders, Terminal units such as radiators etc. Unless there is a collectively efficient system in operation the ultimate overall efficiency will not be as desired.
Proprietary Brands and advanced designs
Proprietary brands such as Viessmann, a world leader in this field have developed technologies such as their stainless steel Inox-radial heat exchangers for natural gas combustion, capable of extracting almost to the end of last wave of thermal energy otherwise just wasted. Vitotronic controls (microprocessor based control system), Vitocell domestic hot water cylinder, lambda pro control combustion controls (a metering system that adjust the combustion process to the properties of any gaseous fuel) are other advanced features developed by them. The ultimate result is a very welcome consistent fuel efficiency of about 98%.
