Arguably, if you've got the kit, they are quicker and easier to
service. The advice from a Keston engineer was that if the flue
gas numbers are OK leave well alone, just clean out the
condensate trap and check the igniter. With an upfiring boiler
you really do need to dismantle and brush all the crud out of
the burner.

Meanwhile hundreds of thousands of people will have read Jeff
Howell's comments and be believing them, thinking him an expert
on boilers rather than a bricklayer which IIRC is his trade.
