Combi boiler problems

Many householders wonder whether Combi boiler problems are common, before they make their replacement boiler decision.  Combi boilers are the choice of many householders and have the convenience of instant hot water’ when required – within limits.

The combination gas boiler is not new. They have a longer history in Europe but have now become the most common gas boiler in the United Kingdom. A quick check with traditional gas boilers reveals two major divergences which could be the source of combi boiler problems or their advantages. The central heating internal hot water system is sealed. Having no open vents there is no requirement for a feed and enlargement cylinder in the attic. The hot water storage tank can also be spared as the heating boiler will have its own hot water storage vessel.

Combination boiler systems offer many room saving and gas economy advantages for the small-scale household. It is possible to set up a complete central heating and hot water system by purchasing only a gas powered combination gas boiler with a balanced flue. Add in radiators and copper piping and you are then able to heat your home. Your first reaction maybe that we had forgotten some component parts. The hot water storage tank, the feed and enlargement cylinder commonly put in the loft, the central heating pump and other component pieces that central heating and hot water systems seem to need.

Surprisingly a combination heating boiler does not require any of these parts. With a combination boiler you can dispense with the hot water storage tank, there is no requirement for an loft based feed and enlargement tank, the other pieces we have named are in reality built into the combi heating boiler. So you can see with a combination boiler you can save a sizeable amount of space within your home.

Domestic hot water is produced as required, turning on a hot water valve will flag the need to the heating boiler. Cold water is quickly heated up by the use of an efficient heat exchanger. Hot water circulating in the heating system is diverted to the heat exchanger. In this way new mains cold water is quickly heated before reaching the hot water tap. The design and ‘instant on’ hot water from the mains can cause combi boiler problems if you are not careful. You can see how energy efficient this type of boilers are by visiting the efficiency database at SEDBUK, click here.

The compact design and advanced electronics mean that combi boilers are more complex than the average or traditional boiler and this can lead to problems and difficulty for the issue to be diagnosed.

combi boiler problems In hard water areas the combi boiler can scale up, like the element in your kettle. This problem requires the heat exchanger to be descaled regularly or replaced in the worst case analysis.

Instant hot water is not instant, there is a slight lag when you turn on the tap.  Also the hot water can stop flowing when someone else turns on several taps at the same time.  This combi boiler problem can be a real nuisance when you thought that you were taking a hot shower! It has a limited hot water production capacity and no hot water storage cylinder.

The shower and hot tap pressure is generated by the mains supply rather than the header pressure from a hot water tank in the loft.  This works well until the summer hosepipe issues arise, when the water companies reduce water pressure.

The sealed system may not be fully sealed and leak pressure over time.  When this happens you will need to top up the water pressure through the combi filling loop.

So combi boilers have problems but remember they have many advantages for a smaller family in a smaller home. The important fact is to ensure that a combi boiler is the right type of boiler for your home and that it is installed by a reputable boiler installer so that you do not have issues with it in the future.

There are various reasons why it is more challenging to install a contemporary condensing boiler and replace an orthodox heating boiler.

If you install a combi boiler your flue exhaust gases will be heavier as they are not as hot and an easily seen condensation plume can result outside from the exhaust pipe as the gases quickly condense. The output gases can then create wet areas near to the outlet, this impact is not restricted to your house and can spill over on to neighboring properties, or worse still the plume can cause problems for people passing by if the flue is badly positioned. There are recommended minimum heights and output flue position guidelines which must be observed.

The design prerequisites for a combi gas boiler flue are different from old boilers and your current flue may not be suitable. To complete the installation you could find that the flue will need to be changed. You cannot share a condensing gas fired boiler flue with any other non-condensing gas appliance.

Putting the gas boiler in the attic often saves room and it is possible providing that the gas boiler is a sealed system. In this situation the loft has to have a drop down loft ladder attached to the hatch. The attic would need to have adequate lighting and a boarded floor to enable access to the gas fired boiler. These requirements are so that subsequent maintenance and servicing can be performed by a central heating engineer.

They do involve fitting a storage cylinder of water and also once the hot water is exhausted your tank will then have to be heated entirely before any more water can be utilised. In this type of heating system the hot water tank will release heat over the years that means this gas boiler is just not as efficient as a combi boiler. Condensing heating boilers do not squander as much energy as older non-condensing boilers. Whenever you choose to install a new central heating boiler you will get one of these new cost effective condensing heating boilers; as heating boiler fitters will not be allowed to install older central heating boiler styles with out a very good reason.
