Not really. Matching the fireplace to the size of your home and heating needs is more efficient. You’ll get more even, comfortable heat when you size your fireplace properly. A 20,000 BTU gas fireplace can generally heat an area between 900 and 1,200 square feet.

Can you heat a room with a gas fireplace?

Overall, gas fireplaces are highly efficient when it comes to heating a room. Once a fire has been burning for some time, it’s likely to heat a room rather quickly. The type of gas fireplace you have is likely to affect the fireplace’s ability to heat a room efficiently.

Do gas fires give off heat?





Gas fireplaces have a wide range of heat output, from about 7,000 to 60,000 Btus. Use this formula to determine which models generate enough heat to warm your room. The formula assumes that your house is well insulated and has tight windows, and that you like the temperature set at 72 degrees F.

Are gas fireplaces worth it?

Unlike wood-burning fires, gas fireplaces are efficient and return as much as “75 to 99 percent of a fuel’s energy back as heat,” according to “This Old House.” Some gas fireplaces have built-in fans which can heat an entire room quickly.

Can you run a gas fireplace all day?

You can run a vented gas fireplace all day with little concern for anything other than gas usage.

Is it OK to leave a gas fireplace on overnight?

An overall rule for safe gas fireplace usage is to not let your fireplace—no matter which style—operate throughout the night. Unmonitored gas fireplaces can lead to dangerous, often fatal, outcomes. The two most concerning outcomes of leaving a gas fireplace on for too long are a house fire or a gas leak.

Is it cheaper to run gas fireplace or central heat?





A modern furnace is more efficient in turning gas into heat than a gas fireplace. This means that although a furnace costs more to run per hour than a gas fireplace, it turns more of that energy into heat and can warm a whole house rather than a single room.

Can you get carbon monoxide poisoning from a gas fireplace?

Yes, gas fireplaces are one potential cause of carbon monoxide poisoning. While there are many potential sources of such exposure, including certain appliances and devices, motor vehicles and wood stoves, gas fireplaces are a common culprit.

How many hours can you run a gas fireplace?

In general, you should not run an unvented fireplace for more than three hours at a time. If you are using natural gas, you can usually run your fireplace for up to four hours before needing to refuel. If you are using propane, the limit is typically two hours.

Do gas fireplaces use a lot of gas?

A standard 20,000 BTU gas fireplace will use about 20 cubic feet of natural gas per hour. Given that price of natural gas is about $1.09 per 100 cubic feet, running a standard-sized gas fireplace will cost about $0.22/hour at 100% heating output. In short: Gas fireplaces are quite inexpensive to run.

Will a gas fireplace work during a power outage?



Gas & wood fireplaces will continue to work safely during a power outage. These fireplaces do not require electricity for venting and can be used safely during a power outage.

What is better electric or gas fireplace?

Electric heaters and gas fireplaces both produce heat immediately once activated. However, gas fireplaces tend to be better than electric units for heating larger rooms because of their higher heating capacity. You may also feel gas heat more quickly than electric heat if you’re standing further away in a room.

Do you need a blower for a gas fireplace?

Gas fireplaces do not need a blower. Gas fireplaces can be used for hours without a blower as long as the gas fireplace is well vented. This is because a gas fireplace blower is an external unit. It is not an in-built part of the gas fireplace, so the gas fireplace can function without the blower.

Do gas fireplaces need to be vented?



While wood-burning models are the age-old standard, most of today’s new fireplaces are fueled by gas, which eliminates the messy ashes and soot leftover from wood fires. Traditional gas fireplaces, like their wood-burning cousins, require an exhaust flue (vent) to remove harmful fumes from the home.

How much heat is lost to a vented gas fireplace?

Natural Vent
The air to fuel the fire is drawn from the indoor air, which is then funneled with the exhaust up a chimney or vent. Since heat naturally rises, fireplaces with natural venting, especially wood-burning fireplaces, can lose up to 90% of the heat.

What is the difference between a gas fireplace and a gas insert?

Gas fireplaces are very similar to gas inserts. They are made the same way, with the box-within-a-box setup. However, the difference between gas fireplaces vs. gas inserts is that a built-in gas fireplace doesn’t require an existing fireplace or chimney.
