Leaving the pilot light on provides instant warmth and convenience but increases gas consumption and utility costs. Factors like frequency of use, fireplace age/condition, and local climate should be considered. Regular maintenance and inspection are crucial for safety and efficiency when leaving the pilot light on.
Pilot lights can be a source of carbon monoxide because the by-products of combustion are released inside the home rather than vented to the outside.
Yes, it can stay on all the time. If you want to turn it off for summer, turn the gas to the fireplace off and it will go out. Then you'll have to relight it in fall/winter when you want to use the fireplace.
LP gas is measured in terms of gallons. There are 92,000 BTU's per gallon. The price of one gallon of LP is $1.10, which means that you will have to pay roughly $5.20 every month to keep your pilot light on.
Appliances that have continuous pilot lights are generally safe providing all the required parts are in place and sealed properly. Many of the appliances have built in safety features to turn the gas off should the pilot light go out.
Protect Your Fireplace
If your fireplace has glass panels, leaving your pilot light on for long periods of time (such as, say, over the summer) can cause sulfur buildup and permanently damage the glass. Additionally, an active pilot light can create moisture, which may collect inside the pipes and cause corrosion.
If the glass is properly sealed and the fireplace is fully vented this fireplace should run continuously without incident. HOWEVER, if you want to err on the side of caution, it is much better to only leave your fireplace burning, no matter what type it is, for two to three hours at a time.
Here's a breakdown:
A fireplace pilot light might consume about 24,000 BTU per day, adding up to about 720,000 BTU a month, or 7.2 therms. If you're paying $1 per therm, then leaving the pilot light on all the time throughout a month might cost you around $7 per month and $84 per year.
This valve operates automatically and shuts off gas flow as soon as the pilot goes out, preventing any risks of excessive gas buildup. That said, even the failsafe system can malfunction, so any time your pilot is out, be sure to carefully check for any strong gas odors, like the scent of sulfur or rotten eggs.
Energy Efficiency: IPI systems are more energy-efficient than standing pilot ignition. The pilot light only ignites when the fireplace is in use, reducing gas consumption and energy costs.
After lighting the pilot, continue to hold the control knob pushed in for 30 seconds. *Pilot lights utilize a safety feature called a thermo coupler. This device needs to be heated up for around thirty seconds, so it can expand and allow gas to flow through safely.
Gas fireplaces are far safer than their wood-burning counterparts—no matches, no smoke, no sparks, no backdrafts, no soot—but that doesn't mean owners should ignore basic precautions. Here are a few things you can do to minimize the dangers posed by even the safest modern fireplace.
Traditional fireplaces can overheat
A gas fireplace allows you to get in there quickly and shut off the gas so things can cool immediately instead of fuming. They can be incredibly unpredictable and can damage the chimney.
Safety. One of the main concerns about leaving the pilot light on during summer is the risk of carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in high concentrations. The pilot light can produce carbon monoxide even when no fire is burning in the fireplace.
Yellow or Brown Stains. Appliances that run on combusting fuel should have unobstructed ventilation. If you notice brownish-yellow or soot-like stains around a heater or gas fireplace, there may be combustion issues. This can be a sign of a carbon monoxide risk.
The pilot light, however, is an actual old-fashioned flame inside your furnace. This flame is supplied by your gas line and should always be lit.
Then look at your gas bill and find out what you pay per Therm. Usually, it is $1 and change. So your pilot can be costing you $7 to $10 per month.
Even if the pilot light goes out and the gas is left running, it is usually not enough to cause danger. In this situation, the gas should be shut off and the area, whether it is an open room or a gas fireplace insert, should be allowed to air out.
Leaving the pilot light on increases the risk of carbon monoxide poisoning, a silent but deadly threat that can result from incomplete combustion in gas appliances.
There are two basic rules for leaving a fireplace operating during the night. DON'T leave the unit on overnight. DO leave the flue open so that excess carbon monoxide is vented. The main concern with a gas-burning appliance is the exhaust of carbon monoxide and leaving the unit on overnight is simply risky.
A pilot light will burn 800 to 1500 BTUs/hr. Your monthly gas bill should include your exact cost per "therm" (100,000 BTUs). Based on this rate you can calculate the cost for your area to operate a pilot light.
If you have either a gas fireplace insert or a direct vent fireplace, you should be able to leave your fireplace on continuously throughout the day. However, it's still very important to monitor your fireplace to make sure it is working properly.
Generally, we recommend turning off the gas pilot light during the summer months. But, remember to schedule fall fireplace maintenance so that a professional technician can inspect your fireplace and keep it in mint condition.
The average cost to run a gas fireplace is $1.20 to $6.30 per day, or $40 to $190 per month when running the fireplace 3 to 6 hours a day. The cost of running a gas fireplace depends on the fuel type, home location, and the fireplace size, type, and efficiency.
