I have an old Barlo combi boiler (must be at least 12 years old) that
has gradually developed a problem over the past couple of months.
The central heating works fine... all radiators quickly heat up without
the boiler seeming to be struggling at all. However, the supply to the
hot taps just won't go above "warm". I'm not sure how reliable the
temperature gauge is, but it never goes above 58 or 60 degrees. This is
the case even when the radiators are piping hot.
It definitely never used to do this, although it's possible the problem
may have been developing over several months (hard to tell in the
summer, but I occasionally found that baths weren't as hot as I'd
Can anyone suggest what might be failing here? And whether it's worth a
repair bill, or whether we should bring our planned autumn boiler
upgrade forward a few months?
