If you have a fireplace with a short lived solid bar log grate that burns up every few years, you really need to switch to a tube fireplace grate heat exchanger. Since they have a fan forcing the hot air out into your home the steel holding the fire does not get hot enough to glow red hot where oxygen attacks the surface causing the scaling that makes solid bar grates burn up.
Instead all that heat conducted from the coals blows out into the room adding a magnitude of additional heat into your home that you would otherwise not get from your fireplace.
Pro tip after many years of experience: spread out the hot coals across the bed of tubes to get the most heat and keep the ash scooped out from below for good combustion airflow.
