Gas Fireplace Installation in Annapolis, MD
A gas fireplace gives you the fire without the firewood, the ash or the wait. Heidler, Inc. installs gas fireplaces and log sets across Annapolis and Anne Arundel County — including the gas supply work, in-house.
Choosing the Right Type for Your Home
There are three broad routes and they suit genuinely different situations. **A gas insert** fits inside an existing masonry fireplace, sealing the opening and venting through the existing chimney. It's the usual answer when you already have a wood-burning fireplace you've stopped using, and it converts a heat-losing hole in the wall into a heat source.
**A built-in direct-vent unit** can go almost anywhere with an exterior wall, since it draws combustion air from outside and vents straight back out. That makes it the option when there's no existing fireplace at all. **A gas log set** drops into an existing firebox and is the simplest conversion, though it's less efficient than a sealed insert.
Which is right depends on what you already have, where the room sits, your chimney's condition, and local code. We assess all of that before recommending anything, because the wrong choice here is expensive to reverse.

The Gas Work Behind the Fireplace
Most fireplace installations need a new gas line run to the firebox, and this is where installations most often go wrong when the fireplace supplier and the gas fitter are different companies. The supply has to be sized for the new appliance alongside everything else already on the system — add a fireplace to a line already at capacity and every appliance on it runs starved.
We do that work ourselves. Supply sizing calculated across the whole system, the line run and pressure-tested, venting installed to the manufacturer's requirements, the work permitted and inspected, and the appliance commissioned with the logs set correctly and combustion verified before we leave. Then annual maintenance keeps it that way.

When to Call for Gas Fireplace Installation
Your Wood Fireplace Goes Unused
An unused fireplace is a hole losing household air up the chimney. Converting it turns a liability into a heat source.
You Want Heat Without the Work
No wood to buy, split, stack or carry, and no ash to shovel. Instant on and off is why most conversions happen.
There's No Fireplace at All
A direct-vent unit can go on almost any exterior wall, so an existing chimney isn't a prerequisite.
Your Existing Unit Is Decades Old
Older gas fireplaces lack modern safety features and burn far less efficiently than current sealed units.

Gas Fireplace Installation FAQs
What's the difference between an insert and a log set?
An insert is a sealed unit that fits inside your existing fireplace and vents through the chimney — far more efficient, because it doesn't lose household air up the flue. A log set sits in the open firebox: simpler and cheaper to fit, but less efficient.
Can I have a gas fireplace without an existing chimney?
Yes. A direct-vent unit draws combustion air from outside and vents straight back out through an exterior wall, so no chimney is needed. That makes it the usual choice for rooms that never had a fireplace.
Do you run the gas line as well?
Yes, in-house. That matters more than it sounds — the supply must be sized for the new appliance alongside everything else on the system, and installations split between a fireplace supplier and a separate gas fitter are where that calculation gets missed.
How long does installation take?
A log set into an existing firebox with gas already present can be a single day. An insert or direct-vent unit with a new gas run and venting typically takes longer, and we'll give you a realistic schedule with the quote.
Will it need servicing?
Yes — annually, before the heating season. Burners collect dust, logs shift, and pilot assemblies need cleaning. [Annual maintenance](/gas-fireplace-maintenance) prevents most mid-winter failures.
