Thanks fr the prompt reply.
I am happy to know that gas ovens are efficient and that you recommend the same. I wud go that way only.
Agreed, conveyor belt needs electric power, but it is very less.. may 200 to 400 watts, this can be managed by a small diesel generator or an invertor. nonetheless i wud need a backup electric source for lights and billing computer.
Thanks a lot again, for the reply.
