“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.”
“Recommended: Sustain Runes & Teleport
Tips: W blocks his Turret AAs. Use Passive shield when going in to kill Turrets. Engage only if he wastes E.”
“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.
“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.”
“Easy matchup, Heimerdinger is very weak this season, and you kill one turret with auto+Q, just go for all-ins against him, and you'll destroy him. At level 1 if you can try to cheese him on a bush or something.”
“Try not to fight with its turrets.
If he pushes you, he'll be easy to gank.”
“His turrets block your hooks and Thresh's immobility and short range makes it difficult to avoid his stun. You also lack the damage to efficiently clear his turrets although you can pull them under turret with Q. Unplayable if he's good.”
“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. ”
“This matchup is going to be HELL. For the first 5 levels, you just need to sit back and make sure not to take damage. Trust me when I tell you that 1 stun grenade, regardless whether he lands the slow or the stun, will lead to you getting chunked from full to half HP INSTANTLY. If you can land a pull, your combo will do a lot of damage to him, as he is innately a squishy champion but trying to do so will leave you vulnerable. Just make sure you SURVIVE until level 6. Give up CS, conserve HP and try to passively exist in your lane. On the bright side, your ultimate CHANGES the entire dynamic. His turrets and etc won't be around to help him in the Death Realm. So look to Ult him either AS he throws out his stun grenade, OR as he puts down his super turret with his ultimate. This way, you will cancel one of his major abilities which will allow you to just walk up and murder him with little resistance.”
“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. AFTERSHOCK IS GOOD TO HAVE IN CERTAIN SITUATIONS. 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. Conqueror is good but Aftershock is great as it allows you to survive his rockets and turret beams. 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.”
