A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Northwood Shropshire SY4 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.
Northwood Shropshire SY4 High Energy Efficiency Combi Boiler Inspection – Many Things You Need to Take Note Of
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.
Why the Condensing Combi Boiler is a Very Popular Unit
By opting for a condensing boiler to convert the 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 the basic working mechanism. The extra bit of efficiency in the 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 homeowner 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 the 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 adjusts 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%.

A gas boiler, fuelled with natural gas or propane, is one kind of appliance used for central heating. 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 maintenance check by a registered gas boiler service heating engineer is very important for safety and efficiency. They will make sure that the heating system is installed according to regulations, that it is safe and it is working efficiently according to the manufacturers’ instructions. If this is done properly every year, gas boiler repair work can be avoided.
In order for the boiler to be serviced properly, it needs to be working.
Gas boiler service varies according to the type of boiler, but there are some things that should be checked on in any boiler. This will be done by the engineer according to the instructions in the manual which came with the boiler when it was installed. The main things that should be checked are:
1. check for leaks
2. check the gas pressure
3. check if it is producing carbon monoxide
4. check if it is functioning properly
5. check the overall condition
6. check the pump and valves
7. check for enough ventilation
8. check the safety and cleanliness of the flue
Old cast iron boilers that have an open flue will need to be dismantled and cleaned which is not needed for modern boilers. They have a systems performance test. Depending on the condition and type of boiler it can take anywhere from half an hour to an hour and a half for a complete gas boiler service. Contractors are often willing to do servicing, especially during the summer, for greatly reduced prices, hoping that you will call them later if you need any gas boiler repair work.
If there is concern that a boiler is not working properly, and gas service is required, there are some things that can be checked:
1. Make sure there is enough water pressure by looking on the pressure gauge. It should show 1.0-1.5 bar.
2. Make sure the pilot light is lit.
3. If the pilot light is lit but there is no hot water, or it is unusually noisy, it may be a gas valve or pump failure in which case an engineer needs to be called.
4. If there is hot water but no central heating, the diverter valve may not be functioning.
5. If the top of the radiator is cold it may need to be “bled”. There is a bleed valve near the top that will release air. If it is cold on the bottom there is most likely sludge or rust blocking the radiator.
If there is no heat at all check the gas and make sure it is turned on as well as the thermostats and control switches. Make sure the pump is running and make sure the pilot light is lit. Many of these minor gas boiler repairs can be done at home with the use of the manufacturers’ manual. If you can identify a problem but are not sure how to fix it even with a manual, call a heating engineer for routine gas boiler service.
