How many fireplaces had grates?? NONE!!
But any fireplace I've ever used had one of these cast iron racks set in it so the fire burned properly!!
And I don't wanna' screw around babysitting my firebox, pulling coals forward, stirrin' them and adjusting the air just to get them to burn... I wanna' load it, and forget it until it's time to reload again. The actual "burning" of firewood should not be a chore or babysitting exercise... I don't wanna' "babysit" my firebox, that's flat ridiculous. When air comes in under the fire all ya' need to do is toss more wood on top, the coals burn hot and into ash
under the new fuel load... rather than the new fuel load smotherin' the coals. Besides, washing air over the top don't make the whole coal bed screamin' hot... it just makes the top layer hot (that ain't enough heat to warm your little willy) and takes near forever to burn down so ya' can add more fuel. The design is a step backwards, not forwards... even cavemen were smart enough to build their fires on top of stones so air could get
under it. The smartest thing I've done in years was to replace that box with one burning on a grate and air coming in under it... the dumbest thing I've done was believing some stupid EPA design bring air in over the top was gonna' give me more heat with less fuel. So far this year, my current "old school" design furnace is producing way more heat, for longer periods using way less fuel than the stupid design did... and all I remove from it is fine ash.
It was 71° in my house this morning at 5 AM also, I loaded the box last night at 6 PM. That's an 11 hour heating cycle, and all I needed to do to get it goin' again this morning was toss some wood in, slam the friggin' door... and walk away!!
