“Heimer is just simply annoying in my experience, very hard to kill him early but he also shouldn't kill you, he's going to just be pushing you in 24/7 so try calling for jungle help pre 6 before he gets his big turret. Try your best to push in this lane and atleast keep it in the middle of the lane, if you ever land an E on him you should be able to kill him quickly in one full combo, but do be careful of stopwatch/zhyonas which they usually get early since their turrets can do the work for them.”
“Only difficult if your jungler never ever ganks. If you have a jungler with brain cells, you'll be okay.A very annoying laner no matter where he goes. If he's feeling extra petty, he'll go top. This is just a farming lane for the most part as he will run from every fight. if he tries to poke with his stun grenade then you have an opening to engage. Make it a very very short fight. PTA rune is recommended and use bushes as a get out method to disengage his turrets. He's terrible at lane control and inevitably overextends which makes him vulnerable to ganks. ”
“Only problem with Heimerdinger is the fact that he'll shove lanes to your tower nonstop. You need a mana item (Abyssal Mask) to keep up with him and shove your waves. You can actually throw his turrets with your E, allowing you to reposition them to better manage your waves. You can even throw his turrets towards your tower so your tower fires at it. He will not be much of a threat at all unless his jungler comes.”
“TL;DR - DIFFICULT MATCHUP. DON’T TAKE TOO MUCH POKE. START DSHIELD +SECOND WIND INTO MERC BOOTS IF YOU HAVE BEEN SUCCESSFUL IN FIGHTING BACK. IF YOU HAVE BEEN GETTING OBLITERATED, GO FOR NEGATRON CLOAK AND FARM UP. YOU OUT SCALE HIM IN 1V1. IF HE GETS COCKY AND STEPS TOO FAR UP, PULL HIM IN AND CHASE HIM DOWN WITH GHOST. ASK FOR JUNGLE HELP IF POSSIBLE. CONQUEROR WORKS SINCE WERE BUILDING DEFENSIVELY. FORCE FIGHTS WHEN HE DOESN’T HAVE TURRETS SET UP/IS NOT NEAR HIS TURRETS. FREE KILL WITH STRIDEBREAKER.
A Heimer lane is poke city. Take EVERY anti poke thing at your disposal. His rockets do so much damage if he lands all of them that you might need to start triple dshield in order to have enough health to actually survive in this lane. On the bright side, he will almost ALWAYS be pushed up so he is very gankable. Not to mention how if he is overconfident and steps too far up, you can run him down. He is low hp so you can kill him very quickly. The trick is not dying after. Even if he isn’t there to attack you, his turrets will be. Unflinching in addition to Second Wind is great. I’d recommend packing tenacity and Rushing Merc boots if you think you have kill pressure on him. If he completely destroys you, just give up and build Negatron Cloak. On the bright side, you outscale him in the 1v1 as you tend to be very tanky so as long as you dont die and get whatever farm you can get, you will get to a point where he is free food for you. Feel free to kill his turrets using your Q or W. But later on, they become so tanky that the damage you take while doing so is not even worth killing the turret, especially since Heimer will just put another one down.”
“This is not a lane this is just Torment. You'll be under your turret for the first 15 Minutes of the game making you Question why even bother with this Game?
Take Teleport and Just Farm out the Lane, there's not much you can do here.
Take Corrupting Pot in Lane and Pick up Mercs so you dont get overwhelmed by his damage.
You can beat him if he doesn't have his turrets set-up or if you kill his turrets and still have Most of your Hp.
 Don't ask for ganks just focus on farming till the Laning Phase is over, you will out-scale Hard.”
“Take a few early points into your E so that you're able to farm and clear his cannons. He'll most likely keep you pushed into tower so just try to farm as best as you can and avoid walking up to the wave near his turrets as he deals a lot more damage than expected. Second wind, early boots and health are all very good into this matchup. At level 6 you can try to go for an all in, just make sure you've poke him down to at least 60% with your E. That way you can kill him in one rotation of abilities. If he flashes I'd take the flash, let your jungler know and don't be greedy.”
“Take Fleet Footwork. You can't kill him in lane ever and he pokes you out. If their jungler or mid laner is also AP rush Merc treads against him. If your jungler ganks him you can probably kill him just by running into him and using E, just watch out for his insane burst. If they don't have any frontline for you to ult he outscales you. ”
“Rush mercs+ cowl/hexdrinker and pray you have enough damage to kill him before you die.
If you dont you wont be able to play the lane.
If you do you still wont be able to farm but you can try to kill him on repeat. Farm after he dies when turrets shut down, its all you'll get before he comes back and sets up turrets again. ”
“You can (Q) his turrets and kill them with 2 (AA), so your objective is to focus on this and avoid using abilities, if you prefer to not max (Q). However, if you do max (Q) you can kill his turrets in one (Q) so long as you have the AP early game, which allows allowing you to press your advantage of shoving him back and not setting up a perma shove into your tower. Keep on your toes scout! You need to be vigilant and keep avoiding all of his skill shots. Once his towers are down for a tiny second you can get in and poke him a little or continue to simply take his turrets down until he's out of mana. A good Heimer will keep you pinned under tower all game.
“Avoid fighting him while he has 2-3 turretns around him. Blocking his stun doesnt mean winning the trade because his turrets deal A LOT of dmg early game. At level 6, dont fight him if he spawns the big turret! Wait for it to expire and go back in for the kill.”
