Don't Burn Your Budget: A 5-Step Checklist for Specifying Gas Heaters from Empire Comfort Systems

Who This Is For (And Why You Should Care)

If you're the person in your company who gets handed the "order a heater for the warehouse" task—and you're not an HVAC specialist—this checklist is for you. It's for the office administrator, the facility coordinator, or the purchasing manager who needs to get this done without blowing the budget or creating a headache six months down the line.

I've been managing purchasing for a mid-sized company since 2020. Gas heaters, thermostats, replacement parts—the whole nine yards. I process roughly 60-80 orders a year across about 8 different vendors, and I've made enough mistakes to know what actually matters. This checklist covers 5 steps. Follow them, and you'll avoid the most common pitfalls.

Step 1: Verify Your Gas Type and Venting Setup Before You Even Browse Products

This sounds obvious, but you'd be surprised how often it gets overlooked. Natural gas and propane are not interchangeable. If you order a natural gas unit for a propane line, you're looking at a return, a restocking fee, and a delayed project.

Empire Comfort Systems makes units for both, so you need to know which you have. Check the existing heater's spec plate if there's one installed. Or call your building maintenance person. Or check the utility bill if you're in a larger facility. Don't guess. I had a vendor once sell me a unit with the wrong gas type—the paperwork said "natural gas" but the unit was configured for propane. It took three weeks to sort out. The installer charged me for an extra visit anyway.

While you're at it, figure out the venting type. Direct vent? B-vent? Power vent? Each requires a different setup, and Empire has different models for each. Mixing them up means your installer will show up, look at the wall, and say, "This isn't gonna work," and you'll still pay for their trip.

Step 2: Match the Heater Size to the Space (Not the Price Tag)

Here's where the value-over-price perspective kicks in. When I first started doing this, I assumed the cheapest option that fit the specs was the right call. Three budget overruns later, I learned about total cost of ownership.

A common mistake is buying a heater that's too small because it's cheaper. It'll run constantly, never quite heat the space, and wear out faster. The labor cost to swap it later eats any savings. Conversely, a massively oversized unit short-cycles, wastes energy, and also dies early. The industry rule of thumb is about 30 BTUs per square foot for a typical commercial space, but that varies with ceiling height, insulation, and windows. Empire's technical documentation includes sizing guides. Use them. Or better yet, have your installer run a Manual J calculation. It's an extra hour of their time, but it can save thousands over the heater's life.

My view? The lowest quote has cost us more in 60% of cases. That $200 savings turns into a $1,500 problem when the undersized unit can't keep the warehouse warm and the crew complains.

Step 3: Check Parts Availability Before Confirming the Model

This one took me a while to learn. You can buy a great heater, but if replacement parts are hard to get—or discontinued—you're stuck with a brick when something breaks. Empire Comfort Systems does a decent job with parts availability for current models, but not all models have equal support.

For example, if you're looking at an older model still in inventory, the thermostats or control boards might be harder to find. I've had a situation where a blower motor took 6 weeks to ship because it was a revision that was no longer actively stocked. The heater was only 3 years old. That was a problem.

Ask your supplier: "What are the most likely parts to fail on this unit, and are they in stock regionally?" If they can't answer, that's a red flag. Also check Empire's own parts availability on their site. If a part shows "temporarily out of stock" with no date, think twice.

Step 4: Read the Warranty and Installation Requirements Carefully

This is where the checklist gets boring but necessary. Most heater warranties are contingent on professional installation by a certified contractor. If your building maintenance guy installs it without a license, the warranty might be void. Also, some warranties require annual professional servicing to remain active.

Empire Comfort Systems typically offers a multi-year warranty on heat exchangers (often 10+ years) and a shorter warranty on parts (1-5 years). But here's the detail many miss: labor costs for warranty repairs are often not covered. So even if the part is free, you're paying the service call.

I once had a faulty thermostat replaced under warranty. The part was free. The labor and travel cost me $180. That's not unusual, but it's something you should budget for. Ask your vendor for a clear breakdown of what's covered. "Full warranty" can mean very different things.

Also, check the required clearances. Some Empire models need specific distances from walls or combustible materials. It's all in the spec sheet. Your installer should verify these, but if the space is tight, you might need a different model. Better to learn that on paper than during installation.

Step 5: Plan for the Thermostat, Too

It's easy to focus on the heater itself and forget the controls. But the thermostat makes or breaks the user experience. A cheap thermostat that doesn't interface well with your building's layout will result in complaints. "It's too cold in the back corner" or "It's cycling on and off constantly."

Empire offers its own thermostat options, and they're usually designed to work best with their heaters. Third-party thermostats can work, but you might lose some fine-tuned control. For a commercial space, I'd recommend something with programmable scheduling and a remote sensor if the thermostat is in a different zone than the main area.

I've been down the cheap thermostat route. It saved us $40. We spent two months getting calls that the warehouse was freezing, only to find the thermostat in the breakroom read a different temperature than the floor. We replaced it with a unit from Empire's own line. No more complaints. Sometimes the right accessory costs more, but the operational headache savings are real.

Common Errors to Sidestep

• Skipping the spec sheet: I've done it. The unit looked right. It wasn't. Read the dimensions, clearances, and gas requirements thoroughly.
• Assuming "one size fits all": A heater for a 1,000 sq ft office is not the same as one for a 3,000 sq ft warehouse. Even same building, different zones.
• Ignoring the venting path: Running a new vent can be expensive if the old one is incompatible. Check before you buy.
• Not confirming the return policy: If the unit doesn't fit or work, can you return it? Some suppliers charge restocking fees of 25% or more.

Here's the thing: most of these mistakes are preventable. The checklist takes an hour to run through. The cost of not doing it? Easily a multiple of the initial savings. I've got the spreadsheet to prove it.
