A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Wykey 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.
Wykey Shropshire SY4 Super Low Energy Combi Boiler Inspection – 5 Things You Should to Take Note Of
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.
Why the Condensing Combi Boiler is a Very Popular Unit
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.

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.
