I use to have 4 Hagen Tonic heaters and detected no RFI problems. They use
solid state switching and unlike the old mechanical thermostat products of
years gone by, don't arc which was the cause RF noise or worse stick on to
boil your fishy friends.

Subject: [RFI] Aquarium Heater
I am considering purchasing an Aquarium and it will need a heater around 225
watts. I've heard (no pun intended) RFI is a known problem with Aquarium
heaters. Are there any good or bad models I should know about? Anyone have
any experience with this care to share your thoughts?
