What My ‘Heat the Office for Less’ Experiment Taught Me About Buying Heaters

The Meeting That Changed My Purchasing List

It started, like most of my bad ideas, with a complaint from finance. My boss came back from a budget review and asked why our facility heating costs had jumped 18% compared to the previous winter. I didn't have a good answer. I'd just been ordering the same Lasko heater models we'd used for years—they were cheap, available, and quiet enough that nobody complained.

When I first started managing facility purchases in 2020, I assumed the lowest unit price was always the right call. It's tempting to think that way. But two budget cycles later, I realized the simplistic 'cheapest bid wins' approach ignores operating costs, reliability, and—most importantly—whether the product actually fits the space.

The Year of Trying Everything

In Q3 2024, I decided to run my own little experiment. We have 15 rooms in our office that need supplemental heating: 4 conference rooms, 8 cubicle clusters, and 3 private offices. I bought a mix of units across different tech and price points. Here's what went into the test:

A couple of standard fan heaters (including a Lasko heater that cost $38)
Two oil-filled radiators
One panel heater
A Dimplex 3kW heater (a storage heater model, which I honestly hadn't used before)
A couple of baseboard units

I put them in different rooms and tracked readings from a plug-in power meter over December and January (peak usage months). I also kept a log of complaints. Honestly, I wasn't expecting much from the storage heaters. They're heavy, they take up floor space, and they look like industrial relics.

The Surprising Result

The Dimplex 3kW storage heater in the corner office—you know, the one nobody wanted because it's huge—performed better than anything else. Its kWh draw was 40% lower than the Lasko fan heater in an identical-sized room, while maintaining a more stable temperature. The room never felt stuffy or drafty. People actually preferred it (finally!).

The cheap fan heaters did what they promised: they blew hot air immediately. But they cycled on and off constantly, and the temperature in those rooms swung by about 5°F throughout the day. They also kicked dust around, which triggered a couple of allergies in one team member (ugh).

The Myth of 'One Size Fits All' Heaters

It's tempting to think you can just buy a water heater element or a space heater and call it a day. But the B2B reality is different. The 'always get three quotes' advice ignores the transaction cost of evaluating different tech types and the value of matching a product to a specific use case.

Here's what I learned to ask before ordering any heater now:

How long is the space occupied? — If it's a conference room used for two-hour meetings, a fast fan heater is fine. If it's a desk someone sits at for eight hours, a storage heater with better heat retention makes more sense.
What's the ceiling height? — Standard ceiling? Any heater works. High ceilings in our lobby? The fan heater barely made a difference; the infrared panel was better.
What's the existing HVAC situation? — We use a heat pump system for baseline heating. The heaters supplement rooms that are colder because of poor insulation or glass walls. Heat pumps provide efficient baseline heat; I don't need supplemental tech fighting against them.

The vendor who helped me select the Dimplex storage heaters told me outright: 'This isn't right for the conference rooms. You'd be overpaying for thermal mass you won't use. Stick with a convection panel there.' That honesty earned my trust for everything else.

The Bottom Line

So what did my experiment cost? I processed a total of about $2,800 in heater purchases that fall. The mix lowered our overall supplemental heating energy consumption by about 15% compared to the previous year (based on plug-load meters). That's roughly $300 in annual savings for a modest investment.

If I had just reordered the same Lasko models, I'd have saved maybe $200 upfront and lost that $300 annually. The real lesson was about matching the tech to the space. Storage heaters Dimplex offers aren't right for every room, but they're excellent for the rooms that need them.

I still use a water heater analogy when explaining this to finance: you wouldn't buy a 5-gallon tank for a high-demand break room. You'd size it based on peak usage. Same logic applies to space heaters.
