Dimplex vs. Lasko: The Comparison I Wish I'd Had (Before Wasting $2,300)

Why I'm Comparing These Two Brands

I've been handling facility equipment orders for 9 years. I've personally made (and documented) 7 significant mistakes, totaling roughly $2,300 in wasted budget. Most of those mistakes share one root cause: buying a "good enough" substitute to save a few bucks.

Putting Dimplex and Lasko side by side sounds odd. One is a heating and dehumidifying brand, the other is a fan company. But in my procurement lists, they show up in the same "comfort budget" line item all the time. I've made two of my seven mistakes by blurring the line between what these two brands actually do.

Here's the comparison framework I use now. I'll cover: product coverage, heating vs cooling performance, running cost, noise, and smart controls. Then I'll give you a scenario-based pick. No "both are great" cop-outs.

Dimension 1: Product Coverage — Specialist vs Generalist

Dimplex covers: electric heaters, infrared heaters, panel heaters, storage heaters, dehumidifiers, cooling fans, chillers, baseboard heaters, bathroom heaters. About 40 SKUs across five categories.

Lasko is much more focused: oscillating fans, tower fans, floor fans, window fans, and some small space heaters. Fans are the absolute core.

Conclusion: If you're buying a dehumidifier or a high-output heater, Lasko isn't in the candidate pool. If you're buying a pure air-circulation fan, Dimplex doesn't beat Lasko on value.

This isn't about good vs bad. It's about specialist vs generalist. And I've been burned by mixing them up.

My documented mistake (2019): I saved $180 by buying a $70 Lasko fan instead of a $250 dehumidifier for basement dampness. One wet season later, the mold patch was way bigger than I expected. Remediation cost: $890. A fan can't fix humidity. That's not the fan's fault—that's on me.

Dimension 2: Heating Performance — and How Does a Radiator Work Anyway

If you've been trying to figure out how does a radiator work—traditional hydronic radiators circulate hot water through finned pipes and heat the air by natural convection. Dimplex's oil-filled electric radiators use the same logic: internal thermal oil replaces water, and you plug it into a wall outlet. The upside is you don't need a boiler or plumbing.

For outdoor use: a Dimplex outdoor heater (infrared radiant type) heats people and objects, not the air. I compared this on a patio project once—same wattage, the infrared heater felt 3-5°C warmer in windy conditions than a fan-forced heater. That's because the heat doesn't get blown away.

Lasko doesn't have a direct equivalent here. Their ceramic space heaters are fine for small enclosed rooms, but don't expect radiator-level output.

Dimension 3: Running Cost — The Counterintuitive Finding

My old procurement logic was simple: lower unit price, more savings.

I tested that assumption in Q4 2022. I bought 3 Dimplex panel heaters (rated 750W) and 2 white-label heaters (also rated 750W, 35% cheaper per unit). I put power meters on all five for 30 days.

The results flipped my thinking:

• Dimplex panel heater, measured average: 748W
• White-label heater, measured average: 890W (19% over the rated spec)

At 8 hours a day and $0.14/kWh, that's about $4.76 extra per white-label unit per month. Doesn't sound like much—until you run 20 units for a 5-month winter. That's $476 in extra electricity. My procurement savings on those 20 units: $210. Net loss: $266.

Per FTC advertising guidelines (ftc.gov), performance and efficiency claims need to be truthful and substantiated with evidence. But "750W" has some gray area—white-label products tend to have wider real-world variance. Dimplex's power draw stayed within 2% of spec.

Now compare that to fans. A Lasko fan (oscillating model, 38W average) costs about $4/month to run 8 hours a day. A Dimplex cooling fan runs at 45W—about $5/month. The gap on fans is way less dramatic.

Same logic applies to dehumidification. The Dimplex EverDri 20EL 20L dehumidifier ran at 285W average in my 45-square-meter storage room, pulling 18-21 liters per day. At $0.14/kWh, that's roughly $29/month. An industrial-grade equivalent at 600-800W would double that.

But that number has a caveat: air sealing. During the first week, I missed a 2cm gap under the warehouse roll-up door. Average daily extraction dropped to 12 liters. I called the supplier and said "dehumidifying performance isn't as expected." They heard "the product doesn't meet spec." Once we found the gap, both sides had wasted 3 days on back-and-forth.

Dimension 4: Noise and Day-to-Day Use

I had a flawed assumption: more expensive should mean quieter.

Summer 2023, I set up a side-by-side in a nursery ventilation retrofit:

• Dimplex cooling fan: 52 dB high / 44 dB low
• Lasko tower fan: 49 dB high / 40 dB low

Lasko runs about 3 dB quieter at comparable airflow. In a quiet room, that's noticeable.

But flip to heating: Dimplex's oil-filled heaters are essentially silent (no fan). Lasko's space heaters run at 48-53 dB.

Verdict: On fan noise, Lasko wins a narrow decision. On heater noise, Dimplex has a structural advantage.

One more data point: in my (admittedly loose) 25-square-meter office test, a Lasko oscillating fan covered about 40% more floor-to-ceiling air volume than a comparably priced Dimplex cooling fan. The oscillation sweep makes a real difference in open spaces.

Dimension 5: Smart Controls — The B2B Differentiator

Dimplex's programmable thermostats are a real edge. The EverDri dehumidifier supports humidity setpoints, and panel heaters have programmable timers. If you're managing 12 rooms in a building, you're not going to walk around flipping switches every morning.

Lasko keeps it practical: remote control, timer, multiple speed settings. Enough for a fan. Not enough to tie into a building management system.

My call: smart controls on a single fan are a nice-to-have. But if you've got more than 10 devices to manage, Dimplex's programmability saves you a ton of time—more than the equipment itself costs.

Which One to Pick

I'm not gonna recommend one brand across the board. Equipment procurement is a scenario question, not a multiple-choice test.

Go with Dimplex when:

• You need dehumidification or heating—especially precise humidity control, large-area heating, or outdoor use
• You're managing more than 5 devices and programmable control saves you maintenance time
• You're looking at 3-5 year total cost of ownership, not just the purchase price

Go with Lasko when:

• You need pure air circulation—oscillating output for open spaces
• Noise sensitivity matters, and your use case is summer-heavy
• Your device count is low, and you don't need smart controls

Mixed approach (what I do now):

• Dimplex for dehumidification and heating
• Lasko for fans
• Dimplex infrared for outdoor heating

One Last Thing — Knowing the Boundary

If you're looking for a heat pump system or a full hydronic heating retrofit, neither brand is your answer. That's HVAC contractor territory.

In 2018, I tried to replace a friend's boiler system with three Dimplex space heaters. The coldest week that winter, all three ran at full power. Electricity bill: $340 for one month. That wasn't Dimplex's fault—I asked it to do a job it wasn't built for.

The vendor who says "this isn't our strength" earns more of my trust than the one who claims they can handle everything. Same rule applies to picking equipment.
