I had an idiot housemate
who couldn't actually understand the concept of adjusting the thermostat, it was up full when she wanted the heating on, which was all the time, I tried repeatedly to educate her but to no avail.

So I took it apart, took the little wheel off and moved it around a quarter turn. Worked a treat :)
