I second the Jager heater. This is an email I received from Drs. Foster and Smith:
We're contacting you with important recall information regarding your Marineland
Stealth Heater (25W, 50W, 75W, 100W, 150W, 200W, 250W) purchased between 2004 - 2009. United Pet Proup (UPG) has determined that a wiring problem can cause the aquarium heaters to overheat or break during normal use, resulting in property damage and posing hazards to consumers.
As a valued customer, your safety and satisfaction is our priority. If you are still using one of the Marineland
Stealth Heaters in question, please take the following steps:
Unplug the heater from the wall to stop the flow of electricity
Let the heater cool for 15 minutes
Remove the heater from the tank
UPG will arrange the return of the recalled model(s) in your possession in exchange for your choice of a free replacement heater (Visi-Therm Deluxe), or full refund. Please contact UPG at (800) 338-4896 between 7:30 am - 5:30 pm EST Monday through Friday to begin the process.
If you'd prefer to arrange your return/refund through Foster & Smith Aquatics, or to discuss trying a Fluval M Submersible Heater as an alternate replacement instead, please contact Customer Service at 1-800-443-1160. Our friendly customer service representatives are always happy to help you, 7 am-10 pm, CST, 7 days a week.
We apologize for any inconvenience this may have caused. Please let us help you continue to enjoy your favorite hobby for many years to come!
Sincerely,
