I've managed procurement for a 90-person commercial facility for six years now—enough time to have audited $180,000 in HVAC spending, negotiated with more vendors than I can count, and built a cost-tracking spreadsheet that the finance team both loves and fears. When people ask me about Dimplex, they get the same response I'd give my own team: here's what I'd ask before spending the money.

Is Dimplex worth the higher upfront cost?

I went back and forth on this one for two weeks before our first big heater replacement. The cheaper units on the market cost roughly half the price per linear foot. On paper, the math was easy. But I knew from past orders that the cheap stuff usually fails faster—and every forced replacement eats whatever you saved on the initial purchase. (I have a two-inch binder of invoices that proves this point.)

Dimplex isn't the cheapest option, but in my experience it's rarely the most expensive when you measure over five years. That's the whole game: total cost of ownership, not the invoice on day one. Plus, the range is a practical advantage. When one manufacturer makes the heaters, the dehumidifiers, and the cooling fans, you spend less time coordinating different vendors and warranties.

Are Dimplex infrared heaters actually efficient?

Let me rephrase that, because "efficient" gets thrown around a lot in marketing copy. What most people mean is: will a lower-wattage infrared unit keep a space comfortable without spiking the electric bill? In my experience, yes—provided it's sized right.

Infrared heaters warm people and objects directly instead of heating the air first. We replaced a 3000W fan heater in our loading dock with a 1500W Dimplex infrared panel, and the dock felt noticeably warmer because the heat wasn't blown away by drafts. The catch: if you install an infrared unit in a room where you actually need to warm the air, you'll be underwhelmed. That's physics, not a brand flaw.

I'll also say this: I trust efficiency claims more when they're verifiable. Per FTC Green Guides (ftc.gov), environmental and energy-efficiency claims have to be substantiated—which is why I keep the published spec sheet for every unit we buy. If a claim can't survive a spec sheet check, it's not a claim, it's a hope.

How do I use the Dimplex fan remote control?

For reasons I'll never understand, this question reaches my desk more than the heaters themselves. With most Dimplex tower fans we've used, the remote is paired at the factory. So when a staff member says the remote doesn't work, I check two things first: the batteries, and whether they're actually pointing it at the unit. More often than not, that's the whole problem.

If the remote still won't respond, I'd check the manual's pairing section. With most of the Dimplex fan remotes I've handled, it's a variation of: press the power button on the unit for a few seconds until the display flashes, then press a button on the remote. But model differences exist, so don't throw the manual away.

How to program a Honeywell thermostat for our heating schedule

If you're asking this, there's a good chance the thermostat is currently winning an argument with the person holding the ladder. Honeywell makes a lot of models, so the exact button labels vary. But the general flow is: choose Menu, then Schedule, then Edit. From there, set the time and target temperature for weekday and weekend periods.

My advice from years of facility thermostats: keep it simple. We run 68°F at 6 a.m. on weekdays, drop to 62°F at 10 p.m., and set the weekend schedule to 58°F. Those settings, paired with Dimplex heaters that have their own programmable thermostats, cut overnight heating costs by about 20% in Q1 2024. The exact result depends on your building, but the principle is the same: a schedule your team can understand is a schedule they'll actually use.

What size Dimplex panel or storage heater do I need?

The quick rule I use for standard 8-foot ceilings is 10 watts per square foot. A 10x12 room, for example, needs at least 1,200 watts. I bump that up when there are big windows, drafty walls, or tall ceilings.

Don't automatically buy the lowest-wattage model the spec sheet lists. There's a trap in that: an undersized heater stays on longer, and a longer-running unit at full output is less efficient than a properly sized one cycling on a thermostat. In 2023 I almost under-specified a small conference room—I had the wattage calculator up, but I'd forgotten to account for a sliding glass door. A colleague caught it before the order went in. That's the closest I've come to losing about $400 in wasted energy over two winters.

Are radiator covers worth the money?

I was skeptical about this one, honestly. Covering a radiator seems like it would block heat. But a cover with proper venting can actually improve airflow and create convection, so the room ends up warm without turning the space into a toaster.

When we added powder-coated aluminum radiator covers in our lobby in late 2023, the goal wasn't energy savings—it was appearance. Client-facing spaces communicate something before anyone speaks. A polished lobby makes the whole service team look more competent. That's not a fuzzy marketing point; it's a procurement perspective on brand perception. The covers also happen to protect visitors from hot surfaces, which made our safety walkthrough happier.

If you're buying radiator covers to save energy, you're probably looking at the wrong solution. If you're buying them to finish a space and make it safer, they're worth considering.

Why is our break-room Frigidaire ice maker not making ice?

Not a heating question, but it's probably in every facility manager's inbox at some point. Our break-room Frigidaire unit stopped producing ice twice in 2024. The first cause: a frozen water line. The second: a clogged filter. In both cases the fix was cheap—a $6 water line and a filter replacement.

Before calling a repair service, I'd check the basics: Is the door fully closed? Is the clean filter light on? Is the condenser dusty? More often than not, one of those is the culprit. A service call for a machine like this can cost more than the replacement part—and knowing the difference is exactly what a cost controller gets paid for.

What should you ask before buying Dimplex products?

What's the five-year total cost, not the price tag. That's the question I wish more people would ask, whether they're buying a $150 panel heater or a multi-thousand-dollar chiller.

In 2024, I compared two quotes for a renovation: one from a vendor at $4,200 that included everything, and one from a vendor at $3,400 that didn't include delivery, mounting hardware, or a control upgrade we needed. The $4,200 quote saved us time and avoided two surprise invoices. That's not a discount you can see in the initial comparison, but it shows up in the budget review.

Dimplex products aren't always the cheapest line item on the quote. But the reason I keep coming back is that the unpleasant surprises are rarer: the heater works, the remote pairs, the thermostat does what the manual says. That's worth something when you're managing a budget.
