we did that when i was a kid. we had central heating where each radiator has some kind of device with material that evaporates depending on how hot the radiator is. the heating bill was based on how much evaporated. we didn't want to save money or the environment, we just liked it a bit cooler. that was decades ago and there was no temperature control on the thermostat. the only way to get to our desired temperature was to turn the heating off.
the result was that measurement devices didn't evaporate at all, and the company had us investigated for cheating. (apparently some people tried to prevent the evaporation by wrapping them in some isolating material.)
