A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in High Ercall 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.
High Ercall Shropshire TF6 Super Low Energy Combi Boiler Inspection – 5 Things You Should to Know
When the cold weather starts to show its nasty face, we all know that it won't be long before the home central heating is switched on to keep us warm. Sometimes though it decides not to work and you have to find someone who knows how to fix it.
A very small percentage of people have their boiler serviced every year without fail, these are the people who prepare for the colder months, knowing that when they need the heating on it will all be fine.
The majority of people though these days seem to forget or just don't bother to have the boiler serviced until it breaks down. The boiler is just like a car, you need to have the car checked over and oil added if needed, otherwise it will eventually breakdown.
I have listed 5 reasons below on why you should have the boiler serviced.
- One of the mains reasons why your boiler should be serviced each year is safety. When a service is carried out the flue pipe that removes the exhaust gas is checked over for leakage. Should a leak in the flue pipe be found, it could be producing carbon monoxide into the room that the boiler is located in, and we all know how dangerous to life it can be.
- We all like to keep warm in the winter months, but can you imagine coming home from work on a very cold evening only to find your home is cold because the boiler has stopped.
- The boiler fitted in your property normally supplies both hot water and heating throughout your home, should the boiler stop working you may find yourself taking a cold shower.
- If your boiler is either a combination or system boiler then it will be fitted with an expansion vessel somewhere, it could be fitted internal of the boiler or fitted externally close to the boiler. This vessel over time will loose its pressure and needs to be reset.
- The boilers of today are very highly tuned to give you the user the efficiency you require, when the service is carried out, the boiler is connected to a gas analyser to check on it efficiency and safety. Should the boiler need adjustments then it can be adjusted and checked over again.
If your boiler is around 11 years old or younger it will most likely be a high efficient condensing boiler. These boilers are not like the old style boilers that went on for many years without having a service. Those boilers were very costly to use, around 40% of your fuel bill went out of the boilers flue.
Today's condensing boilers have an efficiency rating of around 90%, that's a saving of around 30% on your fuel bill, but if fail to have the boiler serviced you will start see your fuel bills rise along with the fuel suppliers regular increase.
It's very important to have a regular boiler service because it will also increase the life of the boiler, if left then the life span becomes very low, and you will be changing the boiler at some stage, and we all know how costly that can be.
Top Tip, When you find someone to service your boiler, if the boiler works by gas then you must use a Gas Safe Registered Engineer to carry out the work for you. You must not use a friend or someone who says don't worry I can do it for you unless they are registered.
The boiler when working keeps us all warm with plenty of hot water, but when it stops it become a headache.
Important Factors to Think About When Considering Whether to Scrap a Boiler
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.

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.
