A fireplace hearth is necessary in most areas per building codes, especially for gas and wood-burning fireplaces. Electric fireplaces may not require a hearth, so check local building codes or ask a pro for guidance if you’re leaning toward electric. A fireplace hearth can decrease the risk of flying embers creating a fire and burning your home down. That’s why fireproof material, like tile, is used for the hearth.

Yes, it is possible to convert a wood-burning fireplace to gas. The average cost for this conversion is $3,000, with a typical range of $500 to $5,500. The project involves running a gas line, professionally cleaning the chimney, and installing gas logs.

Cost factors include the type of gas fireplace and whether a new gas line is needed. Installing a natural gas line can add $200 to $1,000 to the cost. Vented gas fireplaces are more expensive, averaging around $5,000, while ventless options are more cost-effective at about $1,500.

Running a gas fireplace is potentially cheaper than using central heating if you are heating a single room and don’t need to heat the entire house. That's because gas fireplaces are a better source of direct heat, making them more efficient for warming small spaces. Central heating, while more efficient for whole-home warmth, uses more energy overall. Strategically using a gas fireplace, therefore, can help lower heating bills.

Avoid using abrasive cleansing powders on natural stone, as these products could damage the porous material. Using bleach is also a poor idea because of the porosity of the stone. Avoid using a scrub brush with metal bristles, as they could scratch the stone. If you know who manufactured your stone or who installed the fireplace, you may want to contact that entity for any advice on cleaning it safely.
