A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Shawbury 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.
Shawbury Shropshire SY4 High Energy Efficiency Combi Boiler Inspection – Several Things You Need to Know
Combi boilers have a lot of advantages over conventional boilers, but also a few small drawbacks. This article will open your eyes to the things you should consider when purchasing a cheaper model. There are many models of combi boilers available in the market, and like in every other product, the price usually matches the quality and determines the results (you get what you pay for).
1) Possible scaling of the DHW heat exchanger
If the water company in your area, supplies you with hard water, chances are that your DHW heat exchanger will scale with time. In that scenario, you will have two choices; either replace it with an original piece from the manufacturer (which won't be cheap), or replace the whole boiler. Of course this problem can occur with any conventional tank as well, as this is one of the effects of hard waters. The latest and more expensive combi boilers are already designed to reduce scaling as much as possible. Another thing you could do is run softened water through it, but that would definitely invalidate your warranty.
2) No option of electric immersion heater
With a conventional water storage tank, if for some reason the boiler fails, you have the option of using an emergency electric immersion heater. But the combi boiler is tankless and this option would not be valid.
3)Possible incompatibility between gas pipes
You may need to upgrade the gas supply pipe, because the diameter may not comply with the regulations for installing combi boilers.
4)Good showers, slower baths
Although one of the combis' strengths is to be able to deliver high pressurized water in both your hot and cold taps, a cheaper model may have a modest flow rate of hot water. That is no problem if you are a shower person, because it will supply just what you need to take a nice hot shower. Nevertheless, it maybe a little slower for your bathtub to fill up.
5)It does not deliver instant hot water to all taps
If the boiler is far away from the tap you are using, it may take a few minutes for the hot water to come through, as it has to travel through many meters of cold water filled pipes. This is not a problem when filling up a tub or taking a shower, but if you just want instant hot water to wash your hands or fill up a basin, it may be irritating to have to wait and see an amount of cold water being wasted down the drain.
The Condensing Oil Boiler - Is it the Right Choice For You?
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.

Oil fired condensing boilers are just starting to be used in the United States. There are some obstacles to overcome and some great advantages to condensing oil technology.
One of the main reasons that they have not been used more is because of the lack of low-sulphur heating oil being readily available. A condensing oil boiler must burn the low-sulphur heating oil for it to work properly. As more and more of these units are sold in different areas of the US the right fuels will become more readily available.
Modern oil condensing boilers can save you as much as 30% more energy than many conventional boilers. A modern oil condensing boiler will not only heat more efficiently, but because of this it will reduce your heating oil consumption. When low-sulphur heating oil or heating oil with biogenic additives are used in an oil condensing boiler, it then becomes almost as environmentally friendly as using natural gas.
If your boiler is more than 15 years old, replacing it with a new condensing boiler, of the right heat output for your property size, should save you around a third on your heating oil bills. If you plan to install a new boiler or to replace an existing one, in some cases you will need to install a condensing boiler to meet today's higher standards for energy efficiency required under many building codes. Today's new boilers are not only smaller, neater, they also take up less space, Therefore they are much more energy efficient and therefore use less fuel to produce the same amount of BTU's. A typical conventional boiler burns fuel in a combustion chamber that is surrounded by a water jacket. Condensing boilers also extract the heat from the products of combustion using a secondary heat exchanger.
A condensing combi boiler is a boiler that will heat your home and provide you with instantaneous hot water, without adding a hot water tank. Most of these boilers use a coil that is immersed in the hot water inside the boiler. The cold water is run through the coil and the heat is transferred from the boiler water to the domestic water. These boilers make the production of your hot water very efficient also.
Condensing oil boilers basically are not that much different than conventional boilers. They just are designed so that they reduce the flue gases temperature to the point where the water vapor in the exhaust is cooled to the point where it condenses. This condensing feature also releases the latent heat in the flue gases. This heat is also collected and used to heat you home.
Condensing boilers are not only a great deal for new construction, but they can also be used to upgrade many old heating systems. They are nearly the same size as older boilers and in some cases they are smaller. The piping may have to be reconfigured a bit, but a good contractor can fit an oil fired condensing boiler easily into any system. You gain will be a highly efficient and comfortable heating system.
