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

Your gas boiler is a very important part of your home providing hot water and warmth during the cold months. Most people take their boiler for granted it is only when it stops working you realise how important it is.
The position of where your boiler will be in your home could have an impact on what kind of boiler you go for. If you live in a home with more than one bathroom this may impact the kind of boiler you install due to the demands imposed on the system. If you have any plans to extend into your loft this may restrict your ability to go for a regular boiler as they require loft space for feed and expansion tanks.
When looking for a new boiler shop around for the best price and get a variety of quotes from different boiler manufacturers. You will find prices can vary from supplier to supplier. The price of the boiler may include things like delivery and after sales support so make sure you compare like for like.
You may also be able to get your new gas boiler on finance to spread the cost. If you are looking for a British Gas boiler they often do deals for example they are currently running an offer which gives one year interest free credit.
When it comes to buying your new gas boiler keep your prepared budget in mind as a successful sales consultant may try and up sell you lots of extras. This is why it is very important to do your research before you buy. When you get a quote ask for a written quote which is itemised so you know how much you are paying for parts and labour.
When looking for a new gas boiler consider its energy efficiency, more efficient boilers can reduce carbon emissions and will allow you to benefit from reduced heating bills. You may find the more energy efficient boiler shave a slightly higher price however over time you more than make up for this in cheaper utility bills.
There are a few different types of boiler regular system and combi. More often than not the kind of property you live in will determine which the best gas boiler is for you. Living in a flat will most likely lead you to buy a combi boiler. If you live in a large house you may go for a regular or system boiler. If you are unsure talk to an expert you want to make sure you make the right decision before you buy.

A gas boiler problem may be expensive to fix but some kind of gas boiler servicing contract could make it much more affordable should a fault occur.
Read This First Before Replacing Gas Boilers
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
For Quina Brook Shropshire SY4 Systems We Normally Advise Buying From The Worcester Combi Boiler Range
Combi boilers used to be very unreliable and would go wrong regularly, it was only around thirty years ago that Vaillant were the only manufacturers in the UK to have a Model, but in recent years due to technological advances, climate control and the demand for more efficiency, New reliable, highly efficient Combi Boilers now account for over 50% of all new boiler installations in the UK. Combi boiler prices vary due hugely due to brand, dimensions, power consumption and reputation.
They are amazing space saving devices which heat your home and heat your homes water directly from one compact unit. The 'Combi' is naturally highly efficient and does not require a water cylinder or any laborious tanks in the loft. Water is instantly heated and delivered through the taps at mains pressure so you can enjoy powerful showers without the need of a pump.
How A Combi Boiler Works
The Central Heating
When the temperature of your property goes below the required temperature you have set on your thermostat. The thermostat signals to the boiler to fire up the pump inside the boiler. The 'Venturi Effect' into action. The water starts flowing through a narrow gap in the pipe causing pressure to build up, just like when you put your thumb over a garden hose the velocity of the water increases and is this pressure that opens the gas valve.
The gas is ignited and the heat exchanger rapidly heats up a limited amount of water, when the desired temperature is met, the thermostatic element expands, the hot water valve closes and the heating system valve opens. This allows the hot water to escape into and circulate in the central heating system, increasing the heat of your property to your required temperature.
The Hot Water
The hot water is heated similarly to the Central Heating but it is the hot water taps that signals to the boiler to start up. The hot water is heated by taking around 12 litres per minute of mains pressure through the heat exchanger, which transfers the heat from the burning flame to the water. Which is then delivered to the hot water tap.
Applications for the Combi Boiler
The main difficulty is the hot water supply to the taps. Although some manufacturers believe their combi boilers can service multiple bathrooms. Arguing that multiple bathrooms can be supplied sufficiently and depends largely on the lifestyles of the occupants. A combi boiler could feasibly supply larger homes with more bathrooms. However, if for instance bathroom 1 is being used and bathroom 2 was also being used, the combi boiler could not simultaneously supply enough hot water to the taps as the pressure will drop dramatically, meaning both occupants of the bathrooms will experience a poor washing conditions.
We recommend Combi boilers should only be installed in smaller homes with only one bathroom.
