Hi,

I have these very old fashioned radio controlled heaters which turn on at a
certain time and store heat and diepsnse it slowly through the day and they
are absolutely rubbish!

What I was wondering is there perhaps a way to bypass the radio controlled
part to turn them on whenever I want to ?

I assume you are referring to economy 7 heaters.
You do know that the 'instant' heat will be more expensive, perhaps by a
factor of 3?
