Every winter, a version of the same question lands in my inbox: "Which Empire Comfort Systems unit should we buy?"
Not the model—that's what spec sheets are for. The real question is bigger: gas logs or wall heater? And once you own one, is it worth repairing or should you replace it?
I understand why people are looking for a single right answer. There isn't one. I've been managing HVAC purchasing for our company since 2020—roughly 60 to 80 orders a year across 8 vendors, accounting for everything from thermostats to full heater installations. The one thing that experience has taught me is that the "best" choice depends on what you're starting with. And the cheapest-looking option on paper is rarely the cheapest once you run the full numbers.
So let me break this down the way I would for a colleague: three scenarios, three sets of advice.
Scenario A: You Have a Fireplace Opening
If your building has an existing wood-burning fireplace, Empire Comfort Systems gas logs are usually the smartest upgrade. You keep the look and warmth of a fire without the firewood, chimney sweep schedule, or the need to stock a year's worth of logs. In a commercial building, that cleanliness factor gets noticed immediately.
But here's the part people skip. The sticker price of the logs is not the total cost. An old fireplace that hasn't been used in a while might need a chimney inspection, a flue liner, or even masonry repair. In our office, the inspection was $150 and a minor flue retrofit cost another $300. The logs themselves were priced reasonably, but the whole project came in about 25% above the unit price—a gap I don't see anyone warning about in the brochures.
And one more thing: clearances. I assumed our fireplace would fit a standard drop-in set because the opening "looked standard" to me. Didn't verify. Turned out the lintel height was lower than required, and we needed a custom mounting solution. That cost us time and extra money. It's not a reason to avoid gas logs, but it is a reason to get a professional measurement before you order anything.
Scenario B: No Chimney, but You Need Real Heat
A wall heater is the practical play when there's no fireplace. Empire Comfort Systems makes a solid range of wall-mounted gas heaters for spaces where ductwork isn't realistic—garages, workshops, add-on rooms, offices. I've bought these for at least three building types, and they've done the job every time.
The biggest mistake I see is undersizing. The 20,000 BTU unit has a tempting price, but if it's too small for the square footage, it runs almost constantly. Your gas bill takes the hit. And the unit wears out faster.
I went back and forth on this exact decision for our reception area. The 20,000 BTU model was about $400 cheaper than the 30,000 BTU unit. On paper, the smaller one looked adequate. But our building is drafty, with 12-foot ceilings. Running the smaller unit meant it would be working nonstop all winter—higher monthly fuel cost, more wear, and a lifespan cut by years. I chose the 30,000 BTU unit in the end. The math over five years made it the cheaper option. Honestly, it wasn't even close.
Now, the opposite mistake is real too. Oversized units short-cycle, which wastes energy and makes the room feel unevenly heated. The right answer is a load calculation based on your actual space dimensions and insulation. If you're not comfortable doing that math, call Empire's tech support. They'll walk you through it.
Scenario C: You Already Own the Unit and Something Broke
So you're past the buying stage and something just failed. The instinct is to quote a replacement. Hold that thought.
Worn parts, like a valve stem, are often the actual culprit. The valve stem is what opens and closes the gas flow when you turn the knob. If it's stripped or worn, the valve won't open fully—weak flame, slow ignition, or nothing at all. I assumed our wall heater's valve stem was a proprietary piece, and that we'd be waiting weeks for a factory order. Didn't verify. Turned out it was a standard component, priced at around $18. Thirty minutes in, we were running again. Replacing the whole unit would have run us $700 plus installation. No contest.
That said, certain situations genuinely require a full replacement. A damaged heat exchanger is the big one. It can leak carbon monoxide, and that's not something you gamble on. To be fair, FTC guidelines require manufacturers to substantiate safety and efficiency claims—but in practice, real-world performance depends on your installation, gas pressure, and maintenance history. If you suspect a heat exchanger problem, do not try to patch it. Replace the unit.
So the rule I follow: repair the small, wear-and-tear parts first. Replace the safety-critical or sealed components.
The Side Projects Nobody Budgets For
Careful with installation budgets. There are two side projects that always seem to catch people off guard.
Patching a hole in the wall. If you're swapping out an old heater, the new unit might not cover the same footprint. Older heaters were often bigger, and after removing one, you can be left with exposed framing and a hole that's wider than the new unit. Patching a hole in the wall sounds like a small job until you add texture matching and paint into the mix. Our "quick patch" turned into a two-day drywall project. Don't underestimate it.
Screen door replacement. A less obvious cost but a very real one. If part of your plan involves warming a sunroom, screen porch, or installation bay, a torn screen door will let all that heat right out. Replacing a screen door is inexpensive, but it's one of those maintenance items that gets postponed because it doesn't seem urgent. It is urgent when you're paying to heat that space.
How to Decide Which Scenario Applies to You
Here's a simple decision guide:
- You have a functioning fireplace with a sound flue → gas logs are probably your best total-cost option. The upfront work may be more, but the experience and operational efficiency beat anything else in this category.
- You have no chimney and need to heat a specific space → wall heater. Size it from a real load calculation. When in doubt, go up a size.
- A small component like a valve stem, thermocouple, or igniter has failed → replace the part. Individual components ship cheaply—often $5 to $15 via USPS or UPS Ground. Include labor and you're still far ahead of a new unit.
- The heat exchanger or gas valve assembly is damaged → replace the whole unit. There isn't a version of TCO math that makes a compromised safety component worth repairing.
Bottom Line
Choosing between Empire Comfort Systems gas logs and a wall heater isn't a contest between product lines. It's about the physical setup of your building, what you're willing to maintain, and what your total cost will be after installation plus energy usage plus repairs.
I spent about a week going back and forth on our last order. Gas logs were the more appealing choice, aesthetically. But our building didn't have a fireplace that could be converted without major flue work, so the wall heater won. It was absolutely the right decision for the building. The space is consistently warm, the unit needed nominal maintenance, and the only thing I regret is that I didn't budget properly for the wall patch.
If you're in this process now, take the extra day. Map your scenario. Run the actual numbers. It's a lot cheaper than learning the difference between sticker price and total cost the hard way.
