Yeaton Shropshire SY4 Boiler Repairs

A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Yeaton 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.

Yeaton Shropshire SY4 High Energy Efficiency Combi Boiler Inspection – Several 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

Why the Condensing Combi Boiler is a Very Popular Unit

There comes a time in every homeowner's life when they must wrestle with the decision of whether or not they should repair their existing heating system, or bite the bullet and purchase a new one. Boilers and furnaces are one of the most expensive pieces of equipment in your home, so naturally you want to get as many years of service out of them as possible. Yet some times, it just doesn't make sense to make small repairs on a unit well past its prime.

The best way to prolong your system's lifespan is to ensure you have your system professionally serviced annually. This will help ensure the unit is running at maximum efficiency. It will also ensure that small problems are brought to light before they become larger expenses. However, when problems do come up, consider the following:

Is the problem easily fixable?There are many components of a HVAC unit that can easily be replaced; yet when some parts go it is much more difficult to fix. For example, ignition modules, thermocouples, or zone controls are all components that are easily replaced on heating systems. Yet, when a section of your boiler cracks, there is not much you can do except purchase a new unit.

Likewise, on air conditioners and heat pumps - many things can go wrong which are fixable. But when the evaporator coil or the condenser fails they are not easily repaired. And one of these parts needs to be replaced, it is best to replace the other with a compatible unit. Coils and condensers which are not matched can function together, but will not run optimally. Mismatched units will show decreases in performance, increased energy use, and premature system failure. So despite the higher initial cost, it is a smarter move to replace both components at the same time for maximum efficiency and prolonged equipment life.

Is the equipment inefficient?Another point of consideration is whether or not it pays to keep an outdated piece of equipment running in your home. If your boiler or furnace is over 15 years old, the efficiency is probably somewhere between 50-75%. Newer high efficiency models are between 85-95% efficient. Replacing an outdated unit with a new high efficiency model will save you money on your fuel bill.

What can go wrong next? If you have an older piece of equipment, you also must consider what may go wrong next. Making multiple small repairs can add up fast. If your unit is fixable, but the cost of repair is high, you may want to consider replacement. While it will be more expensive up front, you will save money in small repairs down the road, as well as save yourself a few headaches.

For Yeaton Shropshire SY4 Systems We Normally Advise Purchasing From The Our Recommended 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.
