The TfL Journey Planner suggests several routes:

1) Northern Line to Stockwell
Victoria Line to Green Park
Piccadilly Line to Heathrow

Without luggage, that strikes me as by far the best route -
cross-platform at Stockwell and a walk at Green Park. With baggage the
Green Park bit may be annoying.

2) Northern Line to Stockwell
Victoria Line to Victoria
Circle/District Line to South Kensington
Piccadilly Line to Heathrow

Difficult change at South Kensington; gawd knows why it's suggested that
one.

3) Northern Line to Stockwell
Victoria Line to Victoria
District Line to Hammersmith
Piccadilly Line to Heathrow.

Better by far. You've got escalator-walk-stairs at Victoria to cope
with, though.

I'd go through to Embankment and change there, instead of using the
Victoria Line. It might take a few minutes more, but the change involves
a bit less distance to carry a suitcase.
