Hi,

I have a Linea 24 boiler and it's behaving strangely. It's set to run for an hour or so for heating in the morning and evening, with HW on demand.

Every hour or two (that I can tell), it sounds like the fan is starting up like it's about to fire into life. There's no spark ignition or anything like that, just a fan type noise for 10 seconds or so and this is outside of the programmed periods of operation and no HW taps have been turned on.

Does anyone have an idea what it could be, it works fine apart from the HW flow is a bit poor.

Many thanks in advance.

Probably the ignition module needs replacing. It happens a lot with these boilers. The fan noise when there is no call for heat is the boiler pre-heat kicking in, this is normal.
Get a CORGI man to change the ignition board for you as you need to check the min/max gas pressures after fitting the new one.
