Hi,
My friend's 18 year old boiler makes a groaning noise whenever it
cycles on. The noise stops once the boiler cycles off. I am wondering
whether noise reducer gel would be beneficial in this situation.

Has it always done this?
When does the noise start.
Typically, the pump will go on, then the blower, then the pilot light,
followed by the burner.

A groaning noise may well be the bearings on the blower dying.
Oiling/greasing it may stop it for a few weeks to a few years.

Fairly sure that Elans are natural draught with open or balanced flue
variants.
Might be some sort of flame/burner problem. Start with a good clear out
and thorough check over.
