Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillYou're both weak level 1 — he has no grenade stun yet and you just farm, so neither owns it; soak XP outside rocket range.
Level 2HeimerdingerHis turret grid and W rockets wall you off the wave and you still have no shield or combo to answer — he zones freely.
Level 3HeimerdingerWith Q, W and his E grenade up he repositions the grid faster than your single combo point can break it — he keeps the wall.
Levels 4-5HeimerdingerHis E stun grenade peels your E engage and one combo point can't crack a full grid, so he edges 4-5 while you wait for R.
Level 6OrnnR's long-range double knock-up plus E-into-Q-pillar stun locks down an immobile Heimer, and W-Brittle bursts him through the grid.
First itemEven / skillYou're even — your Heartsteel/Sunfire spike lets you tank the grid but his turrets are still chunky, so trade the all-in on his E cooldown.
Two+ itemsOrnnYour free Masterwork upgrades at 13 and chained CC win the teamfight where his stationary turrets can't out-zone your engage.

Early game (levels 1–5)

Heimer's whole early game is the turret grid plus W rockets — he walls you off the minions and chips you while you have no shield and no combo, so Levels 1-3 are miserable. Do not flail your E into the grid trying to engage; you'll eat turret fire and his E stun grenade and accomplish nothing. Soak XP at max range, last-hit what you can with Q's line damage from outside rocket range, and just survive to 3 when W's unstoppable percent-HP poke and shield finally let you trade back.
