                                    Far Infrared observations of the Seyfert galaxies NGC 3227, NGC 4051 and
NGC 4151 are presented. These are the first data from a complete sample
of Seyfert galaxies that is being observed by ISO as part of the ISOPHOT
guaranteed time. The new ISO data, in combination with the IRAS data,
show that the mid to far IR emission in all three objects can be
ascribed to two well defined regimes, namely a warm dust emitting region
which we claim is heated by the emission from the respective active
nuclei and a second colder emitting region which we attribute to dust
heated in star forming regions.
