Default Heater Thermostat Inaccuracy

Greenhouse fan heaters with built in thermostats (Parasine) are very
inaccurate sometimes they can vary by 10 degrees F.
I put my heater thermostat up to max and use a plug in digital thermostat
switch into which the heater plugs in.
I have noticed that the plug gets warm (3kw heater) when the heater is
switched on & thus influences the plug in thermostat. Nevertheless, this
setup is more accurate and the temperature fluctuation between when the
heater switches on & off is far smaller.
Has anybody found any other solutions?

Look back in the Google archive for this group, we've had quite a bit of
discussion in several threads on this in the last week or 3.
Look at

Several good solutions there but do remember you get what you pay for. Poor
regulation costs you money every day, not just on the day you buy the
thermostat.

I accept noticed that the bung gets balmy (3kw heater) if the boiler is switched on & appropriately influences the bung in thermostat. Nevertheless, this setup is added authentic and the temperature aberration amid if the heater switches on & off is far smaller.
