A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Meole Brace 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.
Meole Brace Super Low Energy Combi Boiler Inspection – Several Things You Need to Take Note Of
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.
What Is A Combi Boiler?
By opting for a condensing boiler to convert energy of natural gas to heat your home or apartment you are not only helping yourself by saving on heating bills but also make possible environmental well being while helping the whole world.
Wasted energy = wasted money
Whatever the fuel type may be, is said to be efficient about 90% at the lower end and - 98% at the upper. Your 15 year or so old traditional oil fired boiler is at least 12% less efficient than this. Whether it is gas or oil, you can imagine how much fossil fuel the high efficiency boiler would conserve, how much CO2 emission it would curtail and the pile of moolah you would save during the next 30 or 40 year plus life span.
What makes a condensing boiler more efficient?
A traditional gas burning boiler or a condensing boiler of recent vintage technology is not different to any oil burning boiler in basic working mechanism. The extra bit of efficiency in boiler is due to the condensation of water of combustion from steam state to liquid, releasing the latent heat of vaporisation. (Sadly if not for the condensing boiler, this huge percentage of heat energy will be sent up through the chimney as flue gases, without the home owner having a clue to what's happening). Inherently any boiler can achieve fuel efficiencies of 90% upwards easily.
A centralized heating system, incorporating a condenser boiler depends on several other system components. These would include the control system, DHW cylinders, Terminal units such as radiators etc. Unless there is a collectively efficient system in operation the ultimate overall efficiency will not be as desired.
Proprietary Brands and advanced designs
Proprietary brands such as Viessmann, a world leader in this field have developed technologies such as their stainless steel Inox-radial heat exchangers for natural gas combustion, capable of extracting almost to the end of last wave of thermal energy otherwise just wasted. Vitotronic controls (microprocessor based control system), Vitocell domestic hot water cylinder, lambda pro control combustion controls (a metering system that adjust the combustion process to the properties of any gaseous fuel) are other advanced features developed by them. The ultimate result is a very welcome consistent fuel efficiency of about 98%.

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.
