ORBIS 4 IN 1 RETROFIT BATHROOM

The Domus ORBIS is a 4-in-1 retrofit bathroom heater in white — 2,250 W of PTC heat, 300 m³/h extraction and a 30 W switchable LED light, in an ultra-modern circular fascia, designed to replace an old 3-in-1 infrared unit.

ORBIS or HEATCORE? Same guts, different face

They share almost everything — 2,250 W PTC heat, a 60 W AC motor, 300 m³/h extraction, a 330 × 350 mm cutout, a 390 × 390 mm fascia, a 100 mm duct and 158 mm of depth. The differences are two:

• The ORBIS is circular; the HEATCORE is a flush square. On a ceiling with round downlights the circle reads as intentional; against square vents and skylights the HEATCORE lines up better.
• The ORBIS light is brighter — 1,000 / 1,150 / 1,100 lm against the HEATCORE's 850 / 950 / 900.

✅ They drop into the same hole, so this is a look-and-brightness choice, not an engineering one.

What “retrofit” means, and the number that decides it

This range exists to replace the old three-in-one units with the glowing orange bars. The 330 × 350 mm cutout is close to what many of those left behind, and the 390 × 390 mm fascia covers a ragged old opening.

⚠ Check the clearance above the ceiling before you order. The body is 158 mm deep and the retrofit range wants roughly 200 mm of height above — a low-pitch roof or a duct running over the spot will fail it. That is the figure most likely to stop the job and it appears on no page.

Why PTC beats the infrared bars it replaces

• It self-limits. A PTC element's resistance rises as it heats, so it cannot run away. Infrared bars glow at full heat until switched off.
• It warms air, not one patch of floor, and the circulating fan brings it back down.
• Nothing glows at ceiling level, which matters in a bathroom used at night.

The four functions, and the extraction question

• Heater — 2,250 W PTC.
• Exhaust fan — 300 m³/h through a 100 mm duct, vented outside, never into the roof space.
• Circulating fan.
• Light — 30 W LED, 1,000 / 1,150 / 1,100 lm at 3000 K / 4000 K / 5000 K switchable, CRI above 80.

⚠ 300 m³/h is a modest extraction rate — right for a small or medium bathroom, marginal for a large one that holds steam. If condensation rather than cold is your real problem, ask us about the 500 m³/h AIRSWAY or INFINITY.

Where it works

• Replacing an old 3-in-1 infrared heater — the reason the range exists.
• Small and medium bathrooms and ensuites.
• Ceilings with round downlights, where a circular fascia reads as intentional.
• ⛔ Check roughly 200 mm of clearance above the ceiling first.
• ⚠ For a large or steamy bathroom, 300 m³/h may not be enough.
