Heath, 33, joined Arsenal at the start of the Women's Super League season last month and finally got on the scoresheet in her sixth appearance for the club.
Arsenal had lost 4-1 to Barcelona in their opening fixture, so needed to bounce back against their German visitors and took the lead through a Kim Little penalty in the 21st minute.

Heath then made sure Arsenal had breathing space at the break, pouncing from close range to score after Vivianne Miedema's cushioned header in first-half stoppage time.
Miedema scored herself shortly after half-time, before Leah Williamson put the gloss on the win with four minutes to go.
Arsenal travel to Denmark to take on HB Kobe in their next group match on Nov. 10.
