Yeah the heal on towers only really has an effect early laning, when it does make his tower harder to kill or damage by the enemy laner. Basically him being anywhere near it will let the turret heal slowly, over time it can erase any pokes you've managed to do to the turret, making heimer's turret usually healthier by midgame (as long as he stays in lane)... but after that, it really makes very little difference, since the tower can go down in seconds anyway.

The passives most useful effect is the heal on himself and his allies, which gives him and anyone he is laning with some pretty decent sustain and resist to harass, followed by the heal on minions that can screw up enemy last hits and make his minion line harder to get past, then the heal on his turrets which will occasionally let them get off another shot on a tower or champ trying to kill them. The tower heal is probably the least useful effect, since several minutes of him healing a tower can be undone by a couple of hits from any champ late game.
