We evaluate the fermionic determinant for massless QED2 at finite temperature, in the imaginary time formalism. By using a decoupling transformation of the fermionic fields, we show that the determinant factorizes into the usual, temperature independent expression, times an extra factor which depends on the temperature and on the constant component of the gauge field.
