Abstract
A catalytic tank heater includes a removably attached catalytic heater cartridge having catalytic material. The heater is attached to an LPG tank to position the catalytic heater cartridge to face the tank. The catalytic heater cartridge covers a plenum chamber of the catalytic tank heater. A fuel distribution header and heating element are positioned within the plenum chamber and are controlled to initiate combustion of the catalytic material to heat the tank. Vapor from the tank is provided as fuel to the catalytic tank heater, and is regulated to increase heat output as tank pressure drops. The catalytic heater cartridge can be replaced with a new cartridge while at the location of the tank on a property.
