If you need an Empire Comfort Systems gas heater or fireplace, the most important thing to know is your venting type—not the price, not the BTU rating, and not the finish options. B-vent, direct vent, and vent-free units are not interchangeable. Get this wrong, and you'll be sending it back before the first cold snap.
I've arrived at this opinion over five years of coordinating emergency heating replacements. In my role, I help property managers, general contractors, and facilities teams who discover—usually at 9 PM on a Tuesday, usually in January—that their heating system is dead. The ones who solve it fast know what they're working with. The ones who drag their feet end up paying overnight freight on the wrong unit, then waiting another week for an exchange.
Honestly? The "wrong unit" problem is more common than you'd think. We've rejected deliveries because someone ordered a direct vent heater when their building has a B-vent chimney. That's not a failure of the product. It's a failure of information. This article fixes that.
Why I've Got Strong Opinions About This
In my role coordinating HVAC replacements for residential and commercial clients, I've handled 200-ish rush orders in five years. Maybe 180—I'd have to check the system. But the pattern is consistent.
In March 2024, a property manager called at 7 AM. Thirty-six hours before a city inspection, one of their rental units had no heat. The old wall furnace was beyond repair. Normal equipment lead time: three to five business days. We found an Empire Comfort Systems unit that could drop-ship overnight, paid roughly $180 in extra freight, and had it installed by 4 PM the next day. The inspection passed.
The alternative was a $50,000 non-compliance penalty. That's what "emergency" actually means in this business.
Why do I keep recommending Empire Comfort Systems? Because they're what I'd call the "safe middle." Not the cheapest, not the most expensive, but consistently reliable—and their replacement parts are actually available when you need them. When a heater fails in January, parts availability matters more than any spec sheet.
A note on certification
In the US, gas-fired appliances are certified under ANSI Z21 standards—Z21.47 for central furnaces, Z21.50 for vented decorative appliances. Empire Comfort Systems units are CSA-certified, meaning they meet those standards. If a dealer tries to sell you an uncertified unit, that's a red flag.
Safety certifications aren't a marketing extra. They're the minimum bar for putting a gas appliance in a building.
What Actually Matters When You Buy
1. Venting type—everything else is secondary
If you have an existing chimney or B-vent pipe, you need a B-vent unit. If you have a direct vent through an exterior wall, you need a direct vent unit. Vent-free is a separate category with its own clearance requirements.
Figuring this out takes about thirty seconds. Look at the top of your current unit. Metal pipe going up? That's B-vent. Exhaust going straight through the wall? Direct vent. No vent pipe at all? Vent-free. Done.
2. Match heat output to the room
Bigger isn't better. A heater that's too large short-cycles, wastes gas, and wears out faster. The industry rule: 20-30 BTU per square foot for standard 8-foot ceilings. A 500-square-foot room needs roughly 10,000–15,000 BTU.
The BTU rating is in every spec sheet. The problem is people skip that step and buy based on what "looks right." That fails more often than you'd expect.
3. A gas fireplace is not a gas heater
These get confused more than you'd think. A gas fireplace is built around ambience—glass media, realistic flames, heat as a byproduct. A gas heater is built around BTUs. They have different venting, different clearances, and different purposes.
To be fair, Empire's direct vent fireplaces throw a meaningful amount of heat. But "meaningful" is still less than a dedicated heater. Match the appliance to the job.
4. Ask "what's NOT included" before you ask the price
A $1,200 heater can become a $2,600 project when vent modifications, gas line work, and old-unit disposal get added. I've watched clients learn this the hard way. The dealer who lists every fee upfront—even if the total looks higher—usually costs less in the end. That's not a guess; that's how you avoid surprise invoices.
What Does This Actually Cost?
This pricing was accurate as of late 2024. The market changes fast, so verify current rates before budgeting:
- Empire Comfort Systems gas heaters (B-vent): roughly $900–$1,800
- Direct vent units: $1,200–$2,400
- Vent-free models: $600–$1,200
- Gas fireplace inserts: $1,400–$3,500
- Installation: $400–$1,200 depending on venting complexity
Thermostat kits, floor mounting, higher BTU configurations—all of that moves the number. But these ranges give you a real baseline instead of the "starting at" quote that gets padded later.
Here's the counterintuitive part: the customers who learn this before calling a dealer are the ones who get the better quote. Not because they negotiate harder, but because they don't use up a salesperson's time learning basics. That time gets built into the price one way or another.
People think budget models save money. Actually...
The assumption is that the cheapest unit is the economical choice. The reality is the causation runs the other way: manufacturers who invest in durability and parts support can charge more—because they're worth more. Empire sits in the middle of that spectrum. Not premium, not bottom-tier, but solid.
To be clear, I'm not telling you to ignore other brands. Rheem, Lennox, and Honeywell all make solid equipment. If your building runs on a specific smart thermostat ecosystem, an Empire unit might not integrate cleanly—and that's a legitimate reason to explore alternatives.
When Empire Isn't the Right Answer
There are situations where I tell clients to look elsewhere:
- Custom inserts for masonry fireplaces with unusual dimensions—stock units often don't fit.
- Deep smart-home integration with a specific platform.
- Buildings with integrated heating and cooling systems, like heat pumps. Those don't need a gas heater at all.
- Timelines so tight that only local same-day stock matters. No online order beats a local distributor's shelf.
And no gas appliance is maintenance-free. Empire units are reliable—reliable and maintenance-free are different things. Keep the burner assembly and thermocouple clean, schedule an inspection every couple of years, and you'll avoid 90% of the failures we see on emergency calls.
Bottom Line
Here's the checklist I walk through with every client:
- Confirm your venting type. Before anything else.
- Measure the room and estimate BTU at 20-30 per square foot.
- Ask for itemized pricing: unit, installation, venting work, disposal.
- Buy replacement parts when you buy the unit—waiting until you need them means waiting longer.
- Don't wait for an emergency to learn your system.
An Empire Comfort Systems gas heater or fireplace is a genuinely solid choice when you know what you're buying. Know your venting, match your BTU, and read the fine print. Get those right, and you'll be warm this winter—and probably several winters after.
That's the whole point. Not selling you the most expensive unit. Just helping you avoid a January emergency call.
