A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Walcot Shropshire SY7 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.
Walcot Shropshire SY7 High Energy Efficiency Combi Boiler Inspection – Many Things You Will Want to Take Note Of

Important Factors to Think About When Considering Whether to Scrap a Boiler
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 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
