Is it worth it to replace a Ferroli boiler?

Especially if your Ferroli boiler is old, it may be worth considering a replacement boiler. Spare Ferroli parts tend to be very expensive, and the boilers themselves are unreliable and prone to multiple faults, so even if you fix whatever’s wrong now, you may find the boiler breaking down again in a couple of month’s time.

What to do if your Ferroli boiler timer breaks?

The Fix: The cheap mechanical timers that were often installed in Ferroli boilers tend to be very flimsy and often break if someone tries to turn the timer back. It should be fairly simple to replace the programmer.

What is the fault code for Ferroli iboiler?

Ferroli iBoiler Error Codes Fault Code System Behaviour A01 Ignition error – possible electrode faul A02 Electrode or card error A03 Heating sensor damaged, no water circula F04 Wrong card parameter setting

Is it possible to repair a Ferroli boiler?

Unfortunately, because these boilers are prone to having multiple faults at a time, many engineers (including us) will often refuse to carry out repairs. Ferroli also don’t have their own dedicated engineers, and instead use local contractors who may not have a high expertise level of dealing with this brand.

Why is Ferroli part of the benchmark initiative?

Ferroli is a member of the Benchmark initiative and fully supports the aims of the programme. Benchmark has been introduced to improve the standards of installation and commissioning of central heating systems in the UK and to encourage the regular servicing of all central heating systems to ensure safety and efficiency.

What should I do if my Ferroli boiler fails?

The Fix: An engineer will normally use a foot pump or hand pump to repressurise the vessel – it’s usually a quick fix, but with this brand you may require a replacement vessel first – as again, they are quite cheaply manufactured and and are prone to fail early in the boilers life

How does the 3 function work on the Optimax 25?

Holding the key down for at least 5 seconds turns off the boiler. To turn it back on, press the key again for 5 seconds. Pressing the key resets boiler operation after a lock-out. Pressing the key 3 times within 3 seconds automatically takes you to TEST operation. 3 – Multi-function

What does a Ferroli printed circuit board do?

It constantly checks every process that occurs via the thermostats, switches and sensors . It also enforces the safety parameters, making sure that the boiler ceases to function if any of the internal readings point to any fault in the boilers processes.

What should water pressure be in a manual Ferroli boiler?

In the lower temperatures system pressure should be about 1 bar. Whenever the system pressure drops below 0.5 bar system will need to be refilled. It can done by utilizing a filling loop and air venting the radiators. During normal operation, water pressure in the boiler when hot should be about 1.5 – 2 bars.

Why is the frost protection on a Ferroli boiler?

The electrical circuit of the boiler is designed so that if for any reason the air pressure switch contacts remain closed when the fan stops, the burner will not start up again. The frost protection is a safety device which allows boiler to function properly in temperatures close to freezing point.
