In early November 2023, I opened the electric bill for our main warehouse and said something I don't usually say: "That can't be right."

It was right. Heating costs were up 32% compared to the same month the year before. And I had to explain that to the CFO.

I've been managing procurement for a mid-sized facilities company for about six years. Not a huge operation—about 200 employees across three buildings. But our annual facilities budget sits around $180,000, and I've documented every invoice in our cost tracking system since 2018. It's not an ERP. It's a spreadsheet. But it's the first thing I open when something feels off.

The heat pump rabbit hole

The spreadsheet made it clear: our old electric heaters were running too much, in rooms that didn't need it, at temperatures we didn't need. So I started researching alternatives. The CFO asked directly: "Should we switch to heat pumps?"

If you've ever Googled "what are the disadvantages of a heat pump," here's what you'll find:

  • Upfront cost is real. We got three quotes for a single-zone system: $14,000, $12,500, and $17,500. The cheapest quote didn't include the electrical panel upgrade—that was another $1,800.
  • Cold-climate performance drops. Not a dealbreaker in our region, but it matters when the thermometer says 15°F.
  • Installation isn't plug-and-play. Ductwork, permits, line sets, refrigerant charge. It's a project, not a purchase.
  • Maintenance commitments. Filters, coils, annual service calls. You don't just set it and forget it.

To be fair, heat pumps are genuinely efficient in the right conditions. If you have a well-insulated building and moderate winters, they can beat resistance heating on operating cost. I'm not anti-heat-pump. But the more I looked, the more complicated the math became.

The most frustrating part of the whole process was the "energy efficient" claims. Every equipment vendor used the phrase. None of them pointed me to actual test data. Per FTC guidelines (ftc.gov), efficiency and environmental claims need to be substantiated. "Energy efficient" shouldn't be a sticker you slap on a box—it should come with numbers. If you're making a buying decision, ask for the data, not the tagline.

I don't have hard data on how much a heat pump would have saved us in our specific building. We never installed one. What I can say anecdotally is that the payback on that $14,000 quote looked like 11 years. That's a long time to wait for a return.

Where Dimplex electric heaters actually made sense

Instead of making one big purchase, we broke the problem into zones. It sounds obvious, but it changed everything.

We had:

  • Two small offices that only needed heat during business hours
  • A storage corridor with water lines that needed to stay above freezing
  • A break room with a failed hot water heater
  • A damp basement area near the server room

For the offices, we went with Dimplex electric heaters. I'd searched for "dimplex heaters electric" and kept coming back to their panel heaters with programmable thermostats. "Low wattage" sounded like a downside at first. But for rooms occupied maybe 40 hours a week, a 500W panel heater on a smart schedule blows a 2,000W unit running all day out of the water. Not ideal for every situation, but exactly what we needed.

What sold me was the programmability. We set different schedules for different zones. The warehouse gets heat from 6 AM to 6 PM. The offices follow the workday. The corridor stays at a minimum temperature. That's the smart control piece. In my opinion, the thermostat is worth more than the heater itself.

Then came the surprise: the Dimplex tube heater.

We had a water line running through an unheated section of the warehouse. In previous years, we wrapped it in insulation and hoped for the best. A building engineer friend told us about Dimplex tube heaters—long, low-wattage heaters designed to sit inside pipe insulation and keep the temperature above freezing. It cost about $80 and took 20 minutes to install. That's the kind of boring fix you don't appreciate until you're filing a claim for a burst pipe.

A lesson learned the hard way by many facility managers: the cheapest fix is usually the one that keeps the building from breaking.

The dehumidifier plot twist

Then we found the mold smell.

The basement area near the server room had a persistent dampness problem. Air conditioning helped in summer, but in winter it just felt cold and musty. At first, I considered a heat pump with a dehumidification mode. That felt like the "nice" system solution—until I saw the price.

Someone on the maintenance team suggested a Midea dehumidifier. You know, the white box from every home goods store. I almost laughed when it showed up on the budget request. A portable dehumidifier for a commercial building? But it worked. The basement air was noticeably drier within a week. The musty smell dropped to a level you'd only notice if you were looking for it.

I wish I had tracked the humidity numbers more carefully before installing it. What I can say anecdotally is that we stopped getting complaints about the storage room almost immediately. That's a win.

This was the moment the project shifted. We stopped looking for one perfect system that does everything. We started looking for the right tool for each problem.

The hot water heater moment

The break room hot water heater had been dead for a week. Employees wanted hot water for coffee. I figured I'd keep things consistent maybe Dimplex made one.

They don't, as far as I could find. When I asked the distributor, he said something that stuck with me:

"This isn't our strength. Here's a local plumbing supplier who does it well."

That's rare for a vendor to say out loud. It also earned my trust for everything else. If you ask me, a vendor that knows its boundaries is more reliable than one that claims to do everything. "One-stop shop" sounds great in a brochure. In practice, it often means "we'll figure it out when you order."

We bought a standard 40-gallon hot water heater from the local supplier, paid $2,200 with installation, and closed the ticket. No drama. No heroic efforts. Just a vendor who was honest about what they did and didn't do.

A vendor who says "this isn't my expertise—here's who does it better" becomes the vendor you call first for everything else. That's not a contradiction. It's credibility.

What it all cost

Let me share the numbers as best I can:

  • Dimplex panel heaters: about $1,400 total
  • Dimplex tube heaters: $160
  • Midea dehumidifier: $429
  • Hot water heater, installed: $2,200
  • Minor electrical work: $850

Total: about $5,000. Compare that to the $14,000 heat pump quote. And before you say it—yes, the heat pump would have cooled the building in summer too. But for the spaces that actually needed heating, and the one that needed dehumidification, the mixed approach covered every problem without a $14,000 installation project.

Are the Dimplex heaters as efficient as a modern heat pump? Probably not, in a technical sense. But when you factor in installation, maintenance, and the fact that we only condition spaces when they're occupied, the total cost of ownership makes sense.

The final number that matters: our utility bill this past December was about 18% lower than the year before. That's one winter's worth of data, not a scientific study. Jury's still out on the full heating season. But the direction feels right.

What I'd tell someone in the same position

First, don't let one big quote scare you into the opposite extreme. Heating is a portfolio decision. You might need a heat pump for the main office and an electric heater for the workshop. That's not a contradiction. That's good judgment.

Second, calculate total cost, not just the sticker price. "Low wattage" isn't a negative if it runs shorter and smarter. Ask about installation, maintenance, hidden fees, and the cost of doing nothing.

Third, trust the vendor who says "this isn't my strength." It's a green flag. We ended up with a mix of Dimplex heaters, a Midea dehumidifier, a local plumber's hot water heater, and no regrets about any of it. Every piece does one job, and does it well.

Someone in the industry described it to me like this: using an online printer for standard business cards is fine, but when you need custom die-cut pieces, you call a local shop. Same logic here. Standard spaces, standard tools. Special situations, specialists.

Not the sexiest heating strategy. But it's honest. And it fits the budget.
