Threats to Heimerdinger with this build
In laning phase place your turrents in trinagle shape , make sure that their range is enough to support each other. The key to defeat heimer is take down his turrents while aboiding his poke, so be careful and when your enemy enters the range of your turrents, use your E then hit him with your W he will also get damage from your turrents, if necessary place your ignite on him. If your enemy is long ranged then dont wait him to step on your turrent'a range throw your E and when he is low on health and he is stunned, press R and then hit him with your W always put your ignite to be 100% sure.
If you get ganked and you have more hp than your opponent NEVER flash away stay in your turrents use your E when the enemy is inside your turrents hit them with your R and then use your zhonyans when they are ready to hit you.
