Hot radiators when heating is off

Help! All the radiators heat up when the boiler comes on (even though the thermostat is turned right down and the central heating is off). The house is quite new - 5 years old. Any ideas?...

Motorised valve latched on to bleed position

Excellent - many thanks for your help. How do I reset it or fix it though? The markings on the motorised valve read W, M and H but it seems to be stuck on "M".

Cheers,
Chris
