External Thermal Heater
New sleek design allows you to add a heater without anyone seeing it. This ingenious design attaches inline with your canister filter or return pump. With 5/8" input and outputs, this heater works with virtually all canister filters. No need to worry about broken coils, the traditional metal resistor coils have been replaced by a special polymer sheet, silk-screened with heating ink. Temperature range from 65F to 93F.
