Denmark is heading into its first real heat of the year. DMI’s forecast points to temperatures climbing toward 30 °C this weekend — potentially the season’s first “tropical day” — with the warm spell holding all the way through to Sankthans on 25 June. So it’s worth thinking, now, about how to stay cool.
Here’s the part most people miss: a fan coil isn’t only a winter heater. The same slim panel that warms a room in January can just as easily cool it in a heatwave. The Zealux fan coil works in both directions, all year round.
One unit, two seasons
A fan coil is simple by design: a quiet fan moving room air across a water-fed heat exchanger. What turns it into a year-round comfort unit is the temperature of the water running through it.
- Winter — heating. The fan coil connects to a standard two-pipe central heating circuit, exactly where a radiator would. So it runs on the system you already have — an oil or gas boiler, district heating, or a heat pump — and distributes gentle, even warmth. Swapping a radiator for one is a simple pipe connection.
- Summer — cooling. The same panel can push out cool air instead. The one requirement: cool air needs cold water, and a boiler can’t make that. Summer cooling calls for a reversible heat pump — one that can both heat and cool — to supply chilled water.
Because cooling produces condensation, each unit has a built-in condensate drain to carry the moisture away — no puddles, no fuss.
The practical takeaway: you can fit a Zealux fan coil to your existing central heating today for quiet winter warmth, and add a reversible heat pump — now or later — to unlock summer cooling from the very same panels. Arne Nielsen A/S can advise on the right setup, including a matching Zealux air-to-water heat pump.
Why it shines when the mercury climbs
A heatwave is exactly the moment a Zealux fan coil earns its place:
- Quiet enough to sleep through — as low as 30 dB(A) on the smaller models. A warm night doesn’t have to be a sleepless one, which is why they’re such a natural fit for bedrooms.
- Barely sips power — the fan is the only moving part, drawing around 10 W in everyday use, roughly 0.24 kWh over a full 24 hours.
- Slim, with a choice of finish — from just 145 mm deep, available in grey, white, or black, and mountable on the wall or as a floor-standing unit.
- Smart, 5-speed control — manage it from your phone through the Tuya app. Start cooling on the commute home and walk into a comfortable room.
Four sizes, three finishes
The Zealux Wall-Mounted Fan Coil Unit now comes in four sizes — so there’s a fit for a small bedroom or a large open-plan room — each available in grey, white, or black.
| 020 | 030 | 045 | 065 | |
|---|---|---|---|---|
| Heating output (45/40 °C water) | 1.95 kW | 2.86 kW | 3.94 kW | 5.5 kW |
| Heating output (55/50 °C water) | 2.86 kW | 4.15 kW | 5.49 kW | 7.24 kW |
| Cooling output (7/12 °C water) | 1.62 kW | 2.64 kW | 3.43 kW | 4.81 kW |
| Sound level at 1 m | 30 dB(A) | 32 dB(A) | 40 dB(A) | 40 dB(A) |
| Dimensions (W × D × H, mm) | 980 × 145 × 573 | 1250 × 145 × 573 | 1130 × 178 × 588 | 1385 × 178 × 588 |
| Net weight | 15.5 kg | 19.5 kg | 32 kg | 43 kg |
All models carry a 3-year warranty. The smaller 020 and 030 are the quietest — and slimmest, at 145 mm deep — making them ideal for bedrooms and offices, while the larger 045 and 065 bring more output for bigger rooms. (Always refer to the product sheet and the unit’s nameplate for full specifications.)
Still heating with oil? Think hybrid
Got an oil boiler? You don’t have to choose between keeping it and starting your green transition — a hybrid setup lets you do both, and it’s a sensible way to future-proof your heating.
The idea: a heat pump handles the heating whenever electricity is cheap, while the oil boiler steps in only when power is expensive or the weather turns very cold and you want extra output. You get a heat pump’s low running costs day to day, with the boiler as dependable backup for the coldest snaps. And because that heat pump is reversible, the same system gives you summer cooling through your fan coils.
You can make the boiler greener, too: running it on HVO — a renewable alternative to fossil heating oil, with a far longer shelf life — lowers the carbon of the hours it does run, so even the backup pulls in the right direction.
It’s a gradual, low-disruption path: keep what works, add a heat pump, and move toward lower bills and lower emissions at your own pace.
Want to stay cool this weekend and warm next winter? Talk to Arne Nielsen A/S about the right Zealux fan coil for your home — and, when you want cooling, the heat pump to match (or a hybrid setup if you’re still heating with oil).
