How do you know if E1 or E2 proceeds to form the more substituted (Zaitsev) or less substituted Alkene (Hofmann)?

For E2 I know A bulky Base creates the Hofmann product and non-bulky one goes Zaitsev....

What are the E1 requirements?

E1 gives Zaitsev.

Is it always that E1 gives Zaitsev... I believe I saw a few exceptions or are they exceptions at all??
