A 250 watt Stealth is only rated to heat 75 gallons.
I have 7 Stealth 250s heating a pond close to 1K gallons.... Normally only need 4 but needing the temp 90 degrees in the middle of winter I had to add 3 more.
Are they the greatest thing out there? No. Are they one of the cheapest and most reliable? I think so..... I have had a lot of heaters freak out and cook fish but never had any sort of that kinda trouble OR broken heaters from forgetting to unplug them with the Stealths.
But.... I would have DEFINETLY picked up one of the heaters Big Dave posted a link to in a heartbeat if I would have known about them prior to buying Stealths. That's a NICE friggin piece!!!!
