sorry by the time i wrote my last lenghty reply i got 2 messages already!
firstly,D_Hailsham.... no ihave no chimney breast anywhere in the house as they have all been removed. Aswell as the TRV's i also have a remote control honeywell programmer/thermostat. and a programmer/thermostat on the wall for the downstairs underfloor heating.
all the radiators up stairs are directly under the windows. (2 in my bedroom,as there are two windows). hope this answers your message.
secondly...message to htgeng.... from the reply above u owe me £1 as all the radiators are underneath the windows!. i've never tried this smoke pen theory.
