Absolutely YES!! The fireglass uses less gas. The glass gets hot and reflects the heat back into the room, you are not just getting the heat from the flame. The same holds true for Fire Pits. Tired of sitting around the fire pit and huddling close? Switch out that lava rock to glass and you will feel the difference! Sit back and enjoy the warmth in the area. You will not be disappointed. With Lava Rock, you get ALL your heat from the flame alone which the majority of the heat goes straight up and does nobody any good at all. Plus there is no comparison at all to burning fire wood. Soot is horrible and messy and can ruin your carpet, plus popping and flying embers can ruin your carpet. No popping or flying objects with the glass, and just turn the gas on and light it, and turn it off when you are finished.
