Question 1

Should you buy or build an outdoor fireplace?

Accepted Answer

•

Deciding whether to buy a prebuilt fireplace kit or build one from scratch comes down to aesthetics, available space, and budget. Many homeowners like the convenience and lower cost of prebuilt options—around $1,500—versus the involved planning and construction of a larger fireplace. Another bonus: you can usually move prebuilt units. Custom projects are more common when homeowners have access to a larger budget and more area in the yard to place the fireplace.

Question 2

What to spray in a fireplace for smell?

Accepted Answer

•

When your fireplace is not in use for longer periods of time, such as over the summer, you can keep smells at bay by spraying either a commercial fireplace deodorizing product or a blend of one part distilled white vinegar to one part water around the walls of the fireplace.

Or, you can place a container of charcoal inside the fireplace to absorb odors. Just be sure to remove it before it’s time to start using the fireplace again.

Question 4

Are gas fireplaces more environmentally friendly than wood fireplaces?

Accepted Answer

•

In short, yes, gas fireplaces create fewer pollutants and are considered more environmentally friendly than traditional ones. In general, natural gas fireplaces release only half to two-thirds as much CO2 per unit of heat (BTU) as burning wood. Plus, gas fireplaces emit fewer harmful particles and air pollutants. They can also be about three times as efficient as wood in terms of heating your home, resulting in a much higher level of their energy converting into heat.

Question 5

How long does it take for creosote to build up in a chimney?

Accepted Answer

•

The time it takes for creosote to build up in a chimney can vary depending on how often you use your fireplace and the wood you burn. Creosote can start accumulating after just a few fires, especially if you burn unseasoned wood or allow fires to smolder. Regularly using the fireplace without proper maintenance can lead to significant creosote buildup within a few months. To prevent hazardous buildup, have your chimney inspected and cleaned at least once a year.
