Now you can have gas fireplace embers. And it's hard to know what they are called. If you googled it you may search " embers fireplace ". And it wouldn't miss the mark. A real wood fire doesn't just have burning logs. As the fire continues it creates a bed of glowing coals and embers as the logs begin to fall apart. You can create gas fireplace embers in a gas fireplace by including chips and chunks made from ceramic fiber or volcanic rock that will have a natural glow as the fire heats them. These gas fireplace embers also increase the heat production of the fireplace, since the chunks capture heat and then radiate it into the room. A variety of fireplace rocks and glowing embers sizes and finishes are available to complement the unique design of your embers fireplace.
What do you suggest for a ventless gas fireplace to enhance to fire look? Embers? Rock? or what?
For a ventelss gas fireplace, you will not be able to add any embers to the burner. However, you may be able to add lava rock around the burner base to create a more realistic look. I recommend locating the product literature for the fireplace for further instruction.
If I put a small pile of lava rock around the inside of my woodstove will that help increase efficiency by holding the heat longer?
Likely not. Lava rock primarily serves to add aesthetic value to your appliance. For your wood burning stove, you'd likely be better off making sure your fire brick and fire baffles are in good working order.
Is it possible to use lava rocks in a ventless gas log set that is 5 years old (Martin, model number is LR, serial number is 232244)?
Provided the lava rock is used as intended, meaning that it is simply placed around the log set on the floor of the fireplace and not making contact with the burner or any sort of flame, it is fine to use lava rock with your unit.
What's the difference between "embers" and "cinders"?
Glowing embers are placed in dime-sized pieces atop a vented gas log burner while cinders, lava rock, and volcanic rock, etc., are placed around a vented or ventless burner on the hearth floor for decoration. If you have a vented burner installed in a wood burning (masonry or prefabricated) fireplace, the ember material is somewhat universal. If you have a prefabricated gas fireplace or ventless gas log set, you must use the part number associated with the ember material described in the installation manual.
