The original design of the heating system, was to divert part of the hot air from the furnace, to surround the black water tank, to keep it from freezing. But, if the furnace was shut off, then trouble happened.
Catalytic heaters do not have a forced air fan, therefore they cannot provide any heat to the tanks.
You have to decide which way you want the system to protect itself, or not.
