I think I read somewhere condensing boilers tend to keep themselves
clean thanks to the condensation produced which carries soot away? Could
be nonsense.

Could be. Although the old boiler had a BF flue terminal which would have
allowed in more muck from the air. The condensing one a fan assisted
system so much smaller would have less air flow when not burning?
