About combi boiler repair


combi boiler repair
​Unlike the convention boiler, combination boiler often known as combi provides on-demand heating to your radiators and domestic hot water, where the domestic hot water takes the priority, ever time the hot tap opens the boiler goes through the full cycle of firing. This on off on off causes it to breakdown more than other types of boilers.

The combi boiler doesn’t require a bulky storage cylinder and can easily fit into most kitchens or storage cupboards, making them the ideal system for a small house.

There are several benefits of having a combination boiler their compact size is a particularly attractive feature. By using a combi boiler you will not need a bulky tank or cylinder to feed your home heating and most systems also come with minimal piping, so if you need a new boiler installed it will be relatively straightforward. Combi boilers also use water that feeds directly from the mains, meaning that hot water is always available on-demand and water pressure remains high even after extended periods of heavy use.


How to avoid the need for combi boiler repair


Tip; To avoid this, try to minimize the strain on your boiler and avoid using several different appliances at the same time. Some combi boilers are better than others at adjusting water pressure and larger models will be better at combating any decline in performance due to strain on the system.

Good quality, correctly installed combi boiler requires No combi boiler repair.

Combination boilers come in a range of sizes and style and quality. Whether you’re looking for a cheap boiler or a hoping to buy an eco-efficient model to help make savings on your bills, there will be a combination boiler to suit your home.

The first thing you need to consider is what size boiler do you need, this is a hard one for you, easy for expert to decide (it is important to know that a common mistake inexperienced installers do that often they replace old KW input with the same modern New KW input boiler, forgetting totally the fact that modern condensing boilers are 30 to 40 % more efficient than the old ones), This actually depends on the number of rooms bathrooms and overall size of your home. We will pick your boiler size carefully as it can have a significant impact on your energy bills. Our plumbers/gas heating engineers will be able to talk you through your options and help you make the right decision.

Another thing to consider is how efficient do you need your boiler to be? Boilers are rated on an efficiency scale running from A to G. Boilers rated A are the most energy efficient, named “pre mixed burner”.

Combi boiler breakdown


Combi boiler breakdown

Finding the cause of any combi boiler breakdown efficiently is an easy step providing the gas safe engineer is
a) Experienced with the generic causes of combi boiler breakdown
b) Understand the concepts and principles of combi boiler components and how they actually work.


Understanding Combi boiler breakdown

In order for a Gas Safe Engineer to be able to deal with any combi boiler breakdown efficiently, he must be able to point where the fault is, to do this he must understand the combi boiler sequence of operation.

Typical sequence of operation for combi boiler breakdown

Demand >boiler Thermostat> Over heat thermostat > APS Co-NC >Fan >APS-NO > Ignition/Pilot>FRD>Main Burner

Although there are lots of different types of combi boiler models and many variations, luckily their operating sequences are almost the same as above.
Any Gas safe engineer attending combi boiler breakdown should follow a logical approach including using safe working practices, using specialist instruments to test components in order to spot the faulty part that causes the combi boiler to breakdown.


Generic causes for combi boiler breakdowns
(Gas Safe Engineers only)

  • No power
  • Gas supply
  • Low water pressure
  • Water leaks from the boiler causing low pressure sensor to activate
  • faulty component pump- flow switch, gas valve, diverter valve, Air pressure switch and sensors
  • Blockage causing no primaries flow

What make us special?


Once the faulty part is proved to be the cause of the combi boiler breakdown, then the gas safe engineer must go the extra mile and investigate the cause of the breakdown. There is no point of trying to replace a faulty component in poorly installed/maintained central heating without curing the cause. A typical example such as replacing a combi boiler faulty primary pump with a new one without flushing the system if the sludge proved to be the cause of the combi boiler breakdown, or replacing scaled up plate to plate heat exchanger without installing a water treatment solution.

It is paramount that any gas safe engineer carrying out repairs on combi boilers to replace like for like parts only bought from a reputable wholesaler.
The most common cause of combi boiler breakdowns is a faulty thermistor often thought the PCB (printed circuit board)


Understanding Thermistors

Thermistors do a similar job to thermostats but they work on a different principle. Thermistors work by electrical resistance, a law current around (5 volts dc in most cases) is sent up one wire to the thermistor and down a second wire back to the PCB. The PCB measures the current it is sending to the thermistor and compares it to the current coming back from the thermistor. depending on the current the PCB decides whether to reduce or increase the gas output to the burner (modulating).

The Most common thermistors used are those NTC, very often the PCB indicates that there is a fault, a common mistake service engineer do that they rush to change the PCB.


It is the law that only A COMPETENT person in accordance with the Gas Safety Installation and Use Regulations 1998 (also MUST be (listed) registered gas safe engineer) allowed to repair install or maintain gas installations/appliances in the UK.
