A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Copthorne 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.
Copthorne Super Low Energy Combi Boiler Inspection – A Number of Things You Need to Consider
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 a 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.
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.
For Copthorne Systems We Usually Advise Purchasing From The Worcester Combi Boiler Range
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.
