My betta hangs near the heater

Yup just like the title says. This is my second time having a betta in a legit tank (regulated temp, filter, plants etc)

She’s very active but when chilling, she hangs around the heater, so much so that she wraps herself around it. Is this normal behavior? Could she be cold? Temp at this moment is 76 (24) degrees (I just added water but it’s usually between 76-77). I do live in the Bay Area so it’s been a bit colder out here.

Thoughts???
