Does a standing pilot light give off emissions all the time?
Yes — a standing pilot is a small flame that burns continuously, so it produces a tiny, constant stream of combustion byproducts and uses a little gas around the clock. But on a vented or direct-vent unit, those byproducts go up the flue or outside, not into your room, and the volume is minuscule. Electronic ignition eliminates the standing pilot entirely.
What a standing pilot really does
A standing (continuous) pilot keeps a small flame lit whenever the fireplace is idle so it's ready to light the main burner instantly. Because it's a live flame, it's technically always burning a trace of gas and making the same clean byproducts — a little CO2 and water vapor — just at a tiny fraction of the main burner's output.
On a direct-vent or vented unit, that all leaves the house through the sealed vent or chimney, so it's not an indoor-air factor. What you will notice is a small standing gas draw on your bill and a bit of heat off the pilot year-round.
The tradeoff nobody tells you about
Here's what actually matters in the mountains. A standing-pilot, millivolt system needs no electricity — the pilot's own heat generates the millivolts that run the valve — so it lights and heats with the grid completely down. That's the Valor approach, and it's why we call it power-optional heat; after Helene, the homes that stayed warm were running exactly this kind of setup.
Electronic ignition (Heat & Glo's IntelliFire, Napoleon's system) skips the always-on pilot to save that standing gas, but the basic versions need power — though many, like Napoleon's, carry battery backup so they still light in an outage.
Which one we'd put in
It comes down to priorities. If grid-independent backup heat is the point — and out here it often is — a millivolt standing pilot or a battery-backup electronic system keeps you covered. If you want to save the year-round pilot gas and don't mind that a basic electronic unit sits idle in a long outage, IntelliFire-type ignition is the efficient pick.
Many homeowners run the pilot only in heating season and shut it off in summer. We'll match it to how you actually use the room. Call (828) 545-0525.
