Hello all, I'm considering replacing a semi-functional (decorative) fireplace with either ventless gas logs, or a wood burning insert, which is much more expensive. I live in the city, so wood will not always be easy to obtain. My main concern is for heat, should the electricity go down for any length of time. Does anyone know if the natural gas is dependent on electricity, or how fragile the system could be in a SHTF situation? Thanks!
