A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Homer Shropshire TF13 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.
Homer Shropshire TF13 Super Low Energy Combi Boiler Inspection – 5 Things You Should to Know
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
The Condensing Oil Boiler - Is it the Right Choice For You?
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.

When the cold weather starts to show its nasty face, we all know that it won't be long before the home central heating is switched on to keep us warm. Sometimes though it decides not to work and you have to find someone who knows how to fix it.
A very small percentage of people have their boiler serviced every year without fail, these are the people who prepare for the colder months, knowing that when they need the heating on it will all be fine.
The majority of people though these days seem to forget or just don't bother to have the boiler serviced until it breaks down. The boiler is just like a car, you need to have the car checked over and oil added if needed, otherwise it will eventually breakdown.
I have listed 5 reasons below on why you should have the boiler serviced.
- One of the mains reasons why your boiler should be serviced each year is safety. When a service is carried out the flue pipe that removes the exhaust gas is checked over for leakage. Should a leak in the flue pipe be found, it could be producing carbon monoxide into the room that the boiler is located in, and we all know how dangerous to life it can be.
- We all like to keep warm in the winter months, but can you imagine coming home from work on a very cold evening only to find your home is cold because the boiler has stopped.
- The boiler fitted in your property normally supplies both hot water and heating throughout your home, should the boiler stop working you may find yourself taking a cold shower.
- If your boiler is either a combination or system boiler then it will be fitted with an expansion vessel somewhere, it could be fitted internal of the boiler or fitted externally close to the boiler. This vessel over time will loose its pressure and needs to be reset.
- The boilers of today are very highly tuned to give you the user the efficiency you require, when the service is carried out, the boiler is connected to a gas analyser to check on it efficiency and safety. Should the boiler need adjustments then it can be adjusted and checked over again.
If your boiler is around 11 years old or younger it will most likely be a high efficient condensing boiler. These boilers are not like the old style boilers that went on for many years without having a service. Those boilers were very costly to use, around 40% of your fuel bill went out of the boilers flue.
Today's condensing boilers have an efficiency rating of around 90%, that's a saving of around 30% on your fuel bill, but if fail to have the boiler serviced you will start see your fuel bills rise along with the fuel suppliers regular increase.
It's very important to have a regular boiler service because it will also increase the life of the boiler, if left then the life span becomes very low, and you will be changing the boiler at some stage, and we all know how costly that can be.
Top Tip, When you find someone to service your boiler, if the boiler works by gas then you must use a Gas Safe Registered Engineer to carry out the work for you. You must not use a friend or someone who says don't worry I can do it for you unless they are registered.
The boiler when working keeps us all warm with plenty of hot water, but when it stops it become a headache.
