I am confused as to why my Turbo max boiler is not heating the water at
all. It is coming through the pipes freezing cold. I have tried the
cental heating and this works fine, when the heating is on this also
heats the water temperature to luke warm, but no where near hot.
Can you advise what may be causing this before i have to spend money on
calling a plumber, also how much should the repairs cost. The boiler
is around 4 years old and regularly serviced.
