Choosing a poele

[Mark]

Folks,

Poele shopping.  Does the following spec sound suitable for heating a house of c120m2?

 Puissance : De 0 a 1400 w
 Volume corrige chauffé : Jusqu a 600 m3
  Info :peint.13kw.200 a 500 m3.buches jusqu a 55 cm.foyer fonte.corps acier.

Also, does the insert go right to the top of the chimney?

Anything else to consider?

Thanks. [:)]
