A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Bayston Hill 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.
Bayston Hill High Energy Efficiency Combi Boiler Inspection – Many Things You Should to Take Note Of
Worcester-Bosch are undoubtedly one of the leading manufacturers of gas fired boilers in the UK, with a rich history spanning 50 years of production, Worcester are one the household names to look for when purchasing a new gas boiler for your home.
In August 2012, Worcester announced the launch (although to many say it was a revision) of the new Greenstar CDi Classic Combination Boiler Range.
A total of 8 models of boilers have been launched, they are:
Greenstar 29Cdi Classic - (Formerly Greenstar 27Cdi)
Greenstar 34Cdi Classic - (Formerly Greenstar 30Cdi)
Greenstar 38Cdi Classic- (Formerly Greenstar 37Cdi)
Greenstar 42Cdi Classic - (Formerly Greenstar 42Cdi)
All models are available in either standard natural gas, or in an LPG option for those in remote locations.
So What's The Difference?
Most notably, the Greenstar Classic range have had a whole host of internal upgrades and improvements with the clever introduction of a more energy efficient standby mode. With consumers continually looking at ways to reduce their energy consumption within the home, Worcester have managed to reduce the standby electricity output of the CDi boilers from 9W to just 3.5W in the new CDi Classic Boilers.
This enables customers to benefit from a more energy efficient source of heating and hot water, which will have a positive impact on electricity bills. Therefore keeping a high standard in energy efficiency and maintaining the SEBUK A-Rated performance values in excess of 90% efficient.
The overall outputs of 27kW, 30kW and 37kW within the CDi range have been upgraded to 29kW, 34kW and 38kW in a move which substantially improves performance in flow rates, giving better hot water service to bathrooms and kitchens.
In addition to this increase in performance and reduction in energy consumption, the everyday operation has not been overlooked in this overhaul. The introduction of a magnetic flap access panel has greatly improved upon the Greenstar CDi's original push and click mechanism, a feature which often failed with many years of use.
With peace of mind and reduced costs on everyone's minds, Worcester haven't scrimped on the warranty either, with a current promotion of a full 5 Year parts and labour warranty on the boiler and a huge 10 Year Warranty on the primary heat exchanger.

- Heat load and flow generated precisely to meet the heating system's requirements using a modulating pump
With the introduction of the new Greenstar Classic Combination boilers in 2012, Worcester's continued program of improvements ensures they remain the UK's favoured choice for boiler manufacturer, there is no better time to purchase a combi boiler to reduce bills and save energy.
Read This First Before Replacing Gas Boilers
Gas boilers normally extract the air they require for combustion either from inside the heated area or straight from the outside. Extracting air directly from outside, characteristically via a plastic pipe that moves through an outside wall, is more effective and secure.
This system is generally referred to as 'sealed combustion', since the gas is burned in a chamber that is blocked to engaged areas. This arrangement almost removes any hazard in the event of combustion gases seeping out into engaged areas.
The efficiency of gas boilers can be greatly increased by incorporating motorized dampers that block the flue pipe outlet when the boiler is not in use. This helps in preventing the loss of heated room air between boiler cycles. Another way to increase the efficiency of gas boilers is by using electric ignition. This does away with the necessity for a standing pilot light.
Gas boiler efficiency can also be enhanced by fan-assisted combustion systems, which do not call for a very big natural draft chimney and can be relieved through a minor flue pipe straight through a wall. Gas boilers, in reality, operate best at full load. When their intensity is lessened, they can drop by as much 20 percentage points in efficiency.
If building requirements are diverse, as is common in commercial buildings, multiple boilers are considered to be highly suitable. Generally, small gas boilers that function effectively are considered a better option than the most suitable of the bigger gas boilers. As has been observed, a number of small boilers can function more competently than a single big system. The reason is that each gas boiler can function frequently close to its full load, which is the most important yardstick for a gas boiler to function in an effective manner.

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%.
