Anybody have ideas on the possible sources of bad experiences/high
running costs with underfloor heating.

Electric underfloor heating quite rightly got a bad name for cost and
poor installation as it was a favourite in a number of council built
houses in the 60's and, in true council fashion, was badly designed
and installed.

The experience with water systems is, as you say quite the reverse.
On a sample of 1 my neighbour and I have identically sized houses
built to more or less the same design and the same insulation
standards 10 years ago. Both were self build - he installed
conventional heating I used underfloor. Both use mains gas. The
pattern of occupation of both houses is similar but the heating costs
for mine are consistently 15-20% less than his.
