This is a common issue with heaters and reason why I always recommend that people use two smaller heaters ike you are rather than one larger one. In all honesty, I don't think there are any good heaters anymore, which makes the 2 heater method more important. I have a bunch of really old Jager heaters - they used to be made very well, and now they are not. I've had better luck with Cobalt NeoTherm heaters than Jager but I've also heard of the NeoTherm heaters blowing up (not quite as dramatic as it sounds).
