A combi heating boiler is a type of condensing gas boiler. It delivers water when called for and is the most common form of gas fired boiler in the UK.
Before you purchase a combination boiler you should have an set up study to ensure it can be fitted in your home. If you use a trained heating fitter to conduct a audit they will ensure that you comply with the building rules. Just because you had a traditional gas boiler install does not mean that you can do a direct swap for a condensing gas fired boiler as they have specific installation requirements.
The exhaust gases from the flue tend to be not as hot and hence less buoyant than for an elderly gas fired boiler type as a result they often condense very quickly and form an easily seen plume. You may see surface wetting the regions which are near to the flue exhaust outlet, neighbouring homes can be impacted by this effect, the plume can also cause irritation for any people going by your home.
You could find that your existing flue, whilst acceptable for a noncondensing boiler, is not suitable for your replacement heating boiler. As a result you may need to change the flue. You cannot share a condensing gas boiler flue with any other non-condensing appliance.
A liquid condensate forms within the boiler, and must be able to be released to a acceptable drain or soak away.
Many of these issues have been faced by other householders and there are simple solution is to defeat them. That is why you will want to employ a trained heating boiler installer has that they will know of these tricks. The set up assessment process should estimate the extra cost of the full fitting and compare them with typical fuel economies over the lifetime of the new gas fired boiler.
Whilst you are having the new boiler fitted there are some choices for the fitting. A change of location often results from the new fitting requirements. If your existing gas fired boiler was an open flue or back boiler this will definitely be the case. An external flue is often missing from the fitting of these older heating boiler types.
Most rooms in the home are available for the fitting with the exclusion of the main living room. Sometimes the kitchen is utilised, sometimes a bedroom and on occasion the attic.
Providing you have a sealed system you can instal a heating boiler in the loft. incremental necessities in this situation are that the attic has a lower-down door latch with a attic ladder. Boarded flooring will be needed to facilitate access to the boiler and adequate lighting is it essential. This will enable an heating engineer to get access to the gas boiler for maintenance and servicing.
Gas cost-efficiency and reducing energy consumption is important to us all in present-day times. Ever rising energy costs make it important to get the most out of your boiler and central heating system. The typical UK household spends close to fifty percent of it’s gas costs on boiler gas use. Below we have delineated some ways in which you can take simple actions two lower your modern energy bills.
Check where you are using the gas boiler :
If you have a spare sleeping room that is not being used turn off the gas heating system metal radiator in the room. Why heat rooms which are not going to be used, this only increases your gas consumption. Check that you also closed the entrance door to the room to prevent air flow and chilled draughts.
Use the gas boiler to heat your home rather than other appliances :
The fire is not as cost-efficient as the gas central heating and it will not heat the rest of your home. The presence of the chimney means that a lot of the heat generated passes to the outside, a gas boiler is more cost-efficient than an electric fire.
Draft proof where you have drafts
Drafts bring chilly air into your home wasting gas you have already paid for. Doors are often areas where cold air leaks in so use approved door insulation. You can get foam sealers which will rapidly close any air cracks that have developed between your entrance door or windows and the wall. These type of gaps happen often in elderly houses as the foundations settle. drafts can be hunted down by using a candle flame and checking when it flutters as you move around the room taking care not to spill any hot wax.
Ensure you are wearing warm clothing indoors :
If you are cold in the room put on some more clothing before you move to increase the thermostatic temperature. You can save up to 10% on your heating charges just by cutting the thermostat by 1°.
Make good use of your curtains :
When the sun shines in the wintertime make sure that it can heat your home like keeping the curtains open. External temperatures drop at night and your house can lose a lot of heat through the windows. Drapes can be an extra form of insulation and this time and trim heat loss if they are shut, you can save a considerable amount of money over time with this tactic. Ensure you have thick or lined curtains to make them effective at stopping heat loss.
Advice around the home :
Check your gas boiler and whether it has a hot water cylinder as this should be insulated. The hot water cylinder will hold hot water you have paid for and it is lunacy to allow this to cool down unused throughout the day time.
The use of silver foil on the wall by your radiator can be used to reflect warmth back into the room rather than out into the wall and the outside.
As your system ages sludge accumulates within the pipework. efficiency is reduced and the only way of restoring your central heating system to normal operation is to flush out the contaminants.
Many commercial plumbers offer a powerflush service which will help to remove this contamination build up.
Most systems develop this contaminants irregardless of type, the main influence is the passage of time and hence the older your system the more likely it is to have this problem. If you purchase new central heating radiators or a gas fired boiler you should give serious consideration to powerflushing the system before these new parts are installed. Whilst your new gas boiler is in pristine condition it will soon have contaminants and debris circulating within it as sludge and debris are agitated as the new components are fitted.
You can purchase corrosion inhibitor in the shops which can be added to the heating system and help to slow any contamination buildup.
The other benefits of a powerflush are that it addresses some of the issues below : -
* accumulation of contaminants within the boiler
* circulation problems with your central heating pump
* pipe blockages
* corrosion
* blockages of pipework and other central heating system components
Addressing these issues mean that you can get the following benefits from a powerflush :-
* helping your water pump to last longer as it handles clean water
* heating radiator heating efficiency improvements as colder areas are eliminated
* lower heating bills through improved heating efficiency
* better heat exchanger operation lowering energy consumption
* reduces hydrogen gas build up which can lead to central heating radiator corrosion and reduced heat output
An automated power-flush machine is used to carry out the gas fired boiler and central heating system cleansing. The gas fired boiler and central heating system water is filtered through the machine which extracts the sediment. At the same time new liquid is fed into your heating system. The heating engineer will usually top up the boiler and central heating system by adding a corrosion inhibitor to protect it in future years.
A power flush be completed by a trained operator to see to it that it is completed correctly and does not create a mess.
Restoring a central heating system after an unanticipated problem can cost you a lot of money. You could be without hot water for a period if you had to wait for a plumber to attend the problem. Taking out gas fired boiler or heating care can help to avoid these issues.
Before you buy gas boiler cover there are a number of options to check. The standard cover carries a monthly fee and ensures that an engineer will call to try to repair your gas fired boiler in an emergency. You should expect to see a target of twenty four hours to attend to fix your problem following receipt of the call, remember this is a goal, no policies will give a promise of a response time unless you pay a premium. If you have young children or are elderly you may also find you are given priority without the payment of any extra regular fee.
central heating insurance plan can be extended to insurance other aspects of your home such as the drains or electrical wiring. Naturally the monthly cost will increase as you incorporate extra components.
You will need to check your requirements before you select the appropriate central heating boiler care plan. If your boiler heats both your water and your house, you might want to include central heating with your insurance which will incorporate protection for your radiators. Depending on how old your drains or wiring is you might also want to cover these.
Often a boiler cover plan will incorporate provision of a twelve month heating boiler service. Due to safety considerations we recommend that have an annual gas boiler service whether you have a central heating system cover plan or not. The message is get your central heating boiler serviced yearly, whether you have breakdown insurance or not.
Whilst boiler care insurance costs money regular checks help ensure your heating boiler is working safely and may even help prolong its life saving you money over its lifespan. Often central heating boiler care providers will only offer care when they see that a regular gas boiler service is carried out.
If you do decide to take out central heating system insurance check your policy for the following restrictions:
A restriction on the type of parts and perhaps only one hours labour is sometimes all that is included. Some breakdowns will cost considerably more than this and you will have to pay the difference.
If your central heating boiler is ageing you might find that it is not covered. You should check for this type of restriction before purchasing the plan.
You need to continually critique your plan on renewal as is sometimes some restrictions will now apply to you. Your care may cease once your heating boiler has gone past a certain age.
While you might be able to switch to another gas boiler cover provider, it would be an advantage to have a policy that renews care for the lifespan of your gas fired boiler. The older your heating boiler the more likely you will need care and less likely a new supplier will provide care.
There is sometimes a insurance restriction of two gas fired boiler breakdowns per year. With an older gas boiler should ensure that you have unlimited call-outs.
To reduce your regular charge some suppliers offer a reduced regular charge but charge an excess if you call them out. This tends to be the best option if your gas boiler is relatively new.

It can be agreed that a safe central heating system is a regularly maintained boiler, it could also be a more efficient gas boiler with smaller heating costs. Heating efficiency is improved, trimming back your fuel bills, and you can relax knowing that your gas boiler is working safely. Saving pennies on a boiler service program could cost you a large sum in the long run. Your bike needs regular maintenance, so does your vehicle and even the lawn mower or a squeeky door. A boiler is used constantly and contains fragile electrical components so it cannot escape the need for an annual inspection. Plumber call out charges can be far more than the price of a 12 month overhaul for householders that have not prepared for the worst.
There are a multitude of more things in life to think about in preference to your central heating, this all shifts the minute it breaks down and you have no heating or hot water. Despite ongoing technology advances, the average lifetime of a gas boiler is between ten and twenty years. Although you may need to give more for a new boiler there are further advantages that you gain in terms of increased reliability and improved energy efficiency.
Sediments can build in the heating and greatly reduce its effectiveness, so having it regularly serviced is a sensible move. When you have taken out a gas boiler service plan you will also gain the benefits of an expert assessing your central heating and ensuring that it works safely and efficiently. The plumber will check all the operating aspects of your heating making any adjustments where necessary. Most leading boiler service providers use hand held computers to enable their workforce to analyse how your heating is performing before the case needs to be opened and any parts adjusted or replaced. Capturing the diagnostic output from your boiler enables the service company to equate the operation of your system to the suggested parameters set by the manufacturer giving a more insightful analysis of any problems then can be achieved purely by dissembling the gas boiler unit.
Mid year system servicing
We tend to think of gas boiler as the winter approaches and then decided to schedule the annual heating service, this can be a mistake and the toughest time of the year. Once the first frosts have come along plumbers and heating engineers will be working flat out repairing heating breakdowns and not be available for an annual service inspection so you should avoid the autumn when arranging your 12 month service. Wintertime appointments will seldom be available on a day that fits in with your calendar.
Get a Service to keep your boiler safe
Callout fees and emergency plumbing charges mean that heating breakdowns can easily be more than the cost of a servicing programme. Your family is protected from any gas boiler fumes in addition to reducing the likelihood of a heating breakdown in the future. One of the reasons its so important to maintain and service boilers is because of deadly Co poisoning, also known as the silent killer. Carbon monoxide is absorbed into your bloodstream 240 times more easily than oxygen is. As Carbon Monoxide Gas poisoning is rare its symptoms are not readily identified by homeowners or even medical practitioners. As the results of a poorly maintained gas boiler can be very harmful you’ll find that leading central heating service organisations hire qualified plumbers to carry out the work.
If you don’t take out a 12 month service or boiler maintenance programme you expose yourself to the cost of a gas boiler breakdown in the future. Worryingly, although central heating policies are freely available over 70% of homeowners have not taken advantage of these schemes and are keeping their fingers crossed that they do not have an unforseen heating breakdown. There is a direct correlation between the effective performance of your central heating and the frequency of the maintenance routine. Having it regularly checked and maintained by a reputable plumber will drastically reduce the danger of a gas leak or problem.
Taking the water out of a fully pumped gas heating system makes many maintenance tasks easier. To work on a radiator problem or to extend the system perhaps. This is often executed by the plumber during repair or extension work although some experienced homeowners have been known to empty their own heating systems.
Cleansing the radiators is the most common driver of this action. Before any work is attempted you need to turn off the central heating pump and gas boiler. Prevention of any additional water entering the gas central heating system is also a priority.
The heating system has a header or expansion tank in the attic which will ensure that any water shortfall is topped up. The passage of water in the expansion water tank is controlled by use of a standard ballvalve. As the water level falls, say through Emptying, the ball drops in the tank opening the valve and allowing more water to enter the central heating system. To ensure that the heating system fully empties we need to stop this mechanism. Using a metal or wooden rod to stop the ball leaves are falling in the cystern will stop water entering the system as the water is drained.
When you are confident that you are prevented any further water entering the gas central heating system you should attach a hose pipe to the outlet valve at the bottom of a radiator taking care to ensure the end of the hosepipe is in a empty outside your property. The water from your metal radiator will flow through the hosepipe and out of your metal radiator system. The hosepipe should be attached to one of the lower heating radiators if you intend to clean the whole gas central heating system. Check now that no water is moving into the gas heating system and that the metal radiators are fully emptied before you do any further work.
If you need to end this process promptly you can also vent the bleed valves on the metal radiators on the upper floors. When finished work can now start on the system.
