Why I started looking closer at gas fireplaces
I'm a quality compliance manager at a mid-size HVAC distributor. Every year I review roughly 400 unique items—gas fireplaces, heaters, thermostats, replacement parts—before they reach our contractors. In Q1 2024, I rejected 12% of first deliveries. Not because the parts were broken, but because the specs didn't match what was promised.
Everything I'd read about gas fireplaces said brand reputation is all that matters. In practice, I found that spec-sheet accuracy and dimensional consistency matter way more than the name on the box. This piece is a breakdown of what I've learned from checking Empire Comfort Systems units against their own documentation—and how that compares to what I see in other brands.
I'll walk you through a few key comparison dimensions: size range, heat output, controls, and installation quirks. Not trying to sell you anything. Just what I see from the quality side.
Dimension 1: Size and dimensional consistency
Empire Comfort Systems offers gas fireplaces in a fairly broad size range. Here's what I've seen across their product line:
- Small/compact units: roughly 30–33 inches wide, 18–22 inches tall, 15–18 inches deep
- Mid-size units: 36–40 inches wide, 22–26 inches tall, 18–22 inches deep
- Large units: 42–48 inches wide, 26–30 inches tall, 20–24 inches deep
That's based on spec sheets from their catalog (as of January 2025, verify current listings). For comparison, I've seen other brands where the same model line has dimensional variances of ±1 inch between published specs and physical units. Empire's consistency is noticeably better—usually within ±0.25 inches across multiple units.
The quality check that surprised me: In 2023, we received a batch of 30 Empire fireplaces where the firebox depth was consistently 0.1 inches under spec. That's negligible for most installations, but for a custom surround? It could throw off a trim piece. We flagged it, Empire acknowledged the variance (they said it was within their internal tolerance of ±0.25 inches), and we approved the batch. The point: their tolerances are tight, and their documentation is reliable.
Why does this matter? Because dimensional inconsistency is the #1 cause of installation delays I see. A fireplace that's 0.5 inches wider than expected can mean recutting a mantel or redoing a surround. That's a $200–500 redo depending on materials. Empire's consistency reduces that risk.
Dimension 2: Heat output and efficiency
This is where I see the biggest gap between what's promised and what's delivered—across all brands, not just Empire. But Empire's approach is interesting.
Their gas fireplaces typically list BTU ratings between 20,000 and 60,000 BTU/hr. In my testing (using a standard heat output verification method, not lab-grade), actual output at full flame was within 5% of listed rating for most models. That's solid. I've seen other brands drift by 10–15%.
Counterintuitive finding: The conventional wisdom says bigger BTU = more warmth. In practice, for a typical living room (say 300–400 sq ft), a 30,000 BTU unit running efficiently beats a 50,000 BTU unit that's oversized and cycling on/off. Empire's mid-range units (around 35,000 BTU) seem designed for this sweet spot. They heat steady, don't short-cycle. That's a quality choice, not an accident.
But here's the thing: their high-end units (50,000+ BTU) don't always deliver proportionally more perceived heat. The larger firebox means more glass area, which means more radiant heat loss. So if you're heating a large open-concept space, you need to account for that. The spec sheet says 50,000 BTU, but the room might feel less warm than a smaller unit in a smaller room. Context matters.
(As of January 2025, efficiency ratings for their units range from 65% to 82% AFUE depending on model. Verify current ratings at Empire's website.)
Dimension 3: Controls and thermostats
Empire offers three control tiers: manual valve (basic, no remote), millivolt (with remote), and electronic ignition (thermostat-controlled). I've tested all three.
Manual valve: Simple. Works. If it fails, it's almost always the valve stem or the gas line—rarely the unit itself. No electronics to go wrong. This is the choice for reliability, not convenience.
Millivolt with remote: This is where Empire does well. The remote pairing is consistent—I tested 12 units in a row and all paired within 3 seconds. Compare that to another brand where 4 out of 12 didn't pair on first attempt. That's a 33% failure rate on the first try. Empire's consistency here is notable.
Electronic ignition: More features, more failure points. I've seen thermostat calibration drift by 2–3 degrees in some units after a year of use. That's not unique to Empire, but it's worth noting. The remedy? A simple recalibration, which takes about 10 minutes. Or just accept the slight offset and adjust manually.
Honest take: If you're installing in a rental property or a space where the user won't bother with a manual, go with the millivolt + remote. It's the sweet spot of usability and durability. If you want programmable temperatures, electronic ignition is fine—just check the calibration annually.
Dimension 4: Installation quirks and tech support
Empire's tech support is decent. I called their line (empire-comfort-systems phone number is listed on their website) three times in 2024 with different questions—once about a venting kit, once about a cracked glass panel, once about a pilot light issue. Each time I got a live person within 5 minutes. That's rare in this industry.
The venting rules are straightforward: Empire specifies that their direct vent units require a specific clearance (usually 1–2 inches to combustibles, depending on model). I've seen installers assume they can use generic venting—bad idea. Stick to the Empire-labeled kits. The cost difference is maybe $20, and it saves a $22,000 redo if inspection fails (which I've seen happen).
One thing I wish was better: the instruction manuals. They're adequate but not great. The diagrams are small, the text is dense. If you're a first-time installer, budget an extra 30 minutes to read carefully. After the first unit, it's smooth.
The choice is contextual—not absolute
I can't tell you Empire is the best. I can tell you what I've seen:
- If dimensional consistency matters (custom surrounds, tight spaces), Empire is a strong choice.
- If heat output predictability matters, their mid-range units are reliable.
- If tech support responsiveness matters, they're above average.
But if you're looking for the cheapest unit, Empire isn't it. If you want the most advanced smart-home integration, they're not there yet (no WiFi controls as of early 2025). If you're doing a massive commercial project, their product range might be too narrow for 100+ unit orders.
This approach worked for us, but we're a mid-size distributor with predictable order patterns. If you're a seasonal installer with demand spikes, your experience might differ. I can only speak to what I've checked—roughly 200 Empire units over 4 years.
Whatever you choose, check the dimensions first. Verify the heat output against your room size. And if you're doing a custom surround, give yourself an extra 0.25 inches of clearance. That's 5 minutes of verification that can save you 5 days of correction.
