Ideal Icos sounding like it's working all the time!

[Owen J]

I have what I believe to be a heat only condensing boiler which is about 10 years old (It is an Ideal Icos model).

It is currently coming on for the heating in the mornings and evenings (evenings for hot water too).

My bedroom is directly above the garage where the boiler is fitted and it sounds like it's working sometimes overnight - is this normal?

I'm pretty sure it's not firing up but it's definitely doing something (the fan activating maybe?)

Can someone put my mind at ease please??

This time of year, could be frost thermostat automatically kicking in.

That makes perfect sense coming to think of it - many thanks
