Warm Air heating system - boiler making a clicking noise

[ophiotaurus]

Hi I have a warm air heating system and the boiler is making a clicking sound while the pilot light is firing up.
It's going click click click then lighting up.
What could this be?

It's just the ignition, nothing to worry about. If it is taking longer than usual to ignite, you might be better getting a Gas Safe engineer in to give it a service.

it is probably quite old, and the flame sensor might be failing. It is quite common on older boilers, and a simple repair.

I am close to the sea, and when I had one facing the wind from the shore, used to get through them at about 18month intervals, I presume due to salt erosion. Inland they can last years.

If that's what it is, best to get it fixed quickly, because it will only get worse, and may stop igniting, which will be inconvenient in winter. If you do not have a regular service person, ask around neighbours with similar houses. Warm air is not so common in UK now, but there are parts available and people who specialise in it. It benefits from changing the dust filters.

Thanks for your advise. It was replaced 9 years ago so is probably getting on a bit. We are in NE Scotland so it's probably having to work harder just now.

The age of the boiler depends on the make of the boiler. When was it's last service?

It was last serviced about two years ago 😳

Yeah, defo get it serviced. When the gas engineer comes, just mention any problems. He will check it out for you and let you know if anything needs replacing.
