A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Stretton Westwood Shropshire TF13 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.
Stretton Westwood Shropshire TF13 High Energy Efficiency Combi Boiler Inspection – A Number of Things You Will Want to Know
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.

Why the Condensing Combi Boiler is a Very Popular Unit
Combi boilers used to be very unreliable and would go wrong regularly, it was only around thirty years ago that Vaillant were the only manufacturers in the UK to have a Model, but in recent years due to technological advances, climate control and the demand for more efficiency, New reliable, highly efficient Combi Boilers now account for over 50% of all new boiler installations in the UK. Combi boiler prices vary due hugely due to brand, dimensions, power consumption and reputation.
They are amazing space saving devices which heat your home and heat your homes water directly from one compact unit. The 'Combi' is naturally highly efficient and does not require a water cylinder or any laborious tanks in the loft. Water is instantly heated and delivered through the taps at mains pressure so you can enjoy powerful showers without the need of a pump.
How A Combi Boiler Works
The Central Heating
When the temperature of your property goes below the required temperature you have set on your thermostat. The thermostat signals to the boiler to fire up the pump inside the boiler. The 'Venturi Effect' into action. The water starts flowing through a narrow gap in the pipe causing pressure to build up, just like when you put your thumb over a garden hose the velocity of the water increases and is this pressure that opens the gas valve.
The gas is ignited and the heat exchanger rapidly heats up a limited amount of water, when the desired temperature is met, the thermostatic element expands, the hot water valve closes and the heating system valve opens. This allows the hot water to escape into and circulate in the central heating system, increasing the heat of your property to your required temperature.
The Hot Water
The hot water is heated similarly to the Central Heating but it is the hot water taps that signals to the boiler to start up. The hot water is heated by taking around 12 litres per minute of mains pressure through the heat exchanger, which transfers the heat from the burning flame to the water. Which is then delivered to the hot water tap.
Applications for the Combi Boiler
The main difficulty is the hot water supply to the taps. Although some manufacturers believe their combi boilers can service multiple bathrooms. Arguing that multiple bathrooms can be supplied sufficiently and depends largely on the lifestyles of the occupants. A combi boiler could feasibly supply larger homes with more bathrooms. However, if for instance bathroom 1 is being used and bathroom 2 was also being used, the combi boiler could not simultaneously supply enough hot water to the taps as the pressure will drop dramatically, meaning both occupants of the bathrooms will experience a poor washing conditions.
We recommend Combi boilers should only be installed in smaller homes with only one bathroom.

Oil fired condensing boilers are just starting to be used in the United States. There are some obstacles to overcome and some great advantages to condensing oil technology.
One of the main reasons that they have not been used more is because of the lack of low-sulphur heating oil being readily available. A condensing oil boiler must burn the low-sulphur heating oil for it to work properly. As more and more of these units are sold in different areas of the US the right fuels will become more readily available.
Modern oil condensing boilers can save you as much as 30% more energy than many conventional boilers. A modern oil condensing boiler will not only heat more efficiently, but because of this it will reduce your heating oil consumption. When low-sulphur heating oil or heating oil with biogenic additives are used in an oil condensing boiler, it then becomes almost as environmentally friendly as using natural gas.
If your boiler is more than 15 years old, replacing it with a new condensing boiler, of the right heat output for your property size, should save you around a third on your heating oil bills. If you plan to install a new boiler or to replace an existing one, in some cases you will need to install a condensing boiler to meet today's higher standards for energy efficiency required under many building codes. Today's new boilers are not only smaller, neater, they also take up less space, Therefore they are much more energy efficient and therefore use less fuel to produce the same amount of BTU's. A typical conventional boiler burns fuel in a combustion chamber that is surrounded by a water jacket. Condensing boilers also extract the heat from the products of combustion using a secondary heat exchanger.
A condensing combi boiler is a boiler that will heat your home and provide you with instantaneous hot water, without adding a hot water tank. Most of these boilers use a coil that is immersed in the hot water inside the boiler. The cold water is run through the coil and the heat is transferred from the boiler water to the domestic water. These boilers make the production of your hot water very efficient also.
Condensing oil boilers basically are not that much different than conventional boilers. They just are designed so that they reduce the flue gases temperature to the point where the water vapor in the exhaust is cooled to the point where it condenses. This condensing feature also releases the latent heat in the flue gases. This heat is also collected and used to heat you home.
Condensing boilers are not only a great deal for new construction, but they can also be used to upgrade many old heating systems. They are nearly the same size as older boilers and in some cases they are smaller. The piping may have to be reconfigured a bit, but a good contractor can fit an oil fired condensing boiler easily into any system. You gain will be a highly efficient and comfortable heating system.
