A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Wrockwardine Shropshire TF6 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.
Wrockwardine Shropshire TF6 High Energy Efficiency Combi Boiler Inspection – Several Things You Need to Know
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.
Why the Condensing Combi Boiler is a Very Popular Unit
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.

Maintaining the boiler in a high state of repair should help with limiting any expensive bills in the future for significant repairs or even replacement of the boiler. Maintaining the boiler needn't be time-consuming or expensive. Here are several steps that can be taken to make certain a boiler is able to operate more efficiently for the long-term:
Make certain the boiler manual is kept in a convenient location. Many people will lose or throw the manual for the boiler once it has been installed. But, if you do find that you are experiencing any difficulties in the future, you'll find that the manual can be highly beneficial for troubleshooting the more common issues you are likely to experience. Also, you also want to make certain that you have access to the manual to help with programming the timing or similar settings that you might wish to change in the future.
Put in place a regular maintenance schedule. If you really want to make certain that boiler system is maintained in a full operational condition, you might want to look having a regular 12 monthly service. A professional service is able to check all aspects of the boiler to make certain it is able to run efficiently. Ideally, you want to have a boiler serviced each year prior to the cold weather arriving.
Prevent the boiler from freezing. It is possible to prevent a boiler from freezing in the very low temperatures by leaving the heating on at a low range constantly. You might find that this isn't the most economical solution and therefore you might want to look at other methods for preventing a boiler from freezing. Insulation of all the pipe work is likely to be one of the more effective options.
Have faulty parts and systems replaced. A boiler isn't able to operate to its full efficiency if parts are starting to fail. A thermostat that is getting old is likely to lose its ability to provide accurate readings in relation to the temperature setting. If you constantly have the heating at an unnecessary high level then this is certain to be a waste of energy.
If you do start to notice that a boiler isn't able to operate as efficiently as desired, then it will certainly benefit if you are able to call on the services of the qualified plumbers who will be able to offer the most efficient solution for rectifying the problems.
