A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Meole Brace 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.
Meole Brace High Energy Efficiency Combi Boiler Inspection – Many Things You Need to Consider
The main theory of what a conventional non condensing boiler does is pretty simple. A boiler works by igniting a combustible fuel source (oil, natural gas, or LP gas), with an appropriate air mixture. The heat from the flame and hot combustion gases pass through a heat exchanger within the boiler, where water is heated and then circulated through radiators, under floor radiant tubing, and hot water cylinders throughout the house. The flue gases then escape through the chimney or venting system. A decent amount of heat is wasted with this type of boiler, where the heated gases are just directly vented out. These types of boilers have a lower efficiency rating; no higher than 75%. An efficiency rating is basically a gauge of how much energy the boiler transfers from fuel used to how much heat is supplied to the system.
Condensing boilers work a bit differently. They essentially have some of the same components non condensing boilers do, except for a second heat exchanger. One of the gases produced in the combustion of fuel is water vapour.Where the hot flue gases just got vented out in a traditional boiler; condensing boilers condense these vapours around a second heat exchanger before venting. By the time the gases are ready to be vented out they are much cooler, around 60 degrees Celsius. As a result the vent pipe used in installation can be made of PVC.
With these systems some of the internal components have to be made of more durable material, because the condensed water tends to be acidic with a 3-5 pH. This results in the cost of the condensing boiler being higher than average. The secondary heat exchanger is where the system return enters first. So by the time the water enters the primary heat exchanger it is already been preheated, allowing the boiler to work more efficiently. The efficiency rating from condensing boilers range from between 80% to 98%.
Combi boiler / Combination boiler
Combi boiler / Combination boiler is an excellent choice for homes with limited space. Combi boiler / Combination boiler is a domestic water heater and a central heating system combined into one unit. They have a heating coil inside of them, and function like an unlimited on-demand water heater. Combi boilers don't have cylinders or external holding tanks like traditional systems do, so they can be installed in areas where a typical system would never work.
Condensing Boiler Pros
1 They are fuel economical and have a 15-30% higher efficiency rating than non condensing counterparts
2 Considerable savings on annual energy expenses
3 Most units are very quite ( they make as much noise as a window mounted air conditioner)
4 Many Models could easily fit in a small closet and have combination boiler
5 They are more environmentally friendly with C02 output
Condensing Boiler Cons
1 Initial cost of the unit is more
2 Units need to have the acidic condensate fitted outside or to a waste line
3 The dwelling the boiler is installed in needs to be insulated well, otherwise the heat saved through efficiency will be lost through the walls.
4 Most units need an outdoor weather sensor to operate effectively
Buying a New Gas Boiler - What You Will Want to Know
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.
For Meole Brace Systems We Usually Suggest Buying From The Vaillant 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.
