HEATCORE 4 IN 1 RETROFIT

The Domus Heatcore is a 4-in-1 retrofit bathroom heater — heat, light, exhaust and colour-switchable LED, 30 W lighting, into a 330–350 mm cutout.

⭐ It is a RETROFIT — and the cutout range is the whole question

• ⭐ The 20 mm cutout tolerance is the point of a retrofit product. ⭐ An existing three-in-one unit will have left a hole somewhere in that band, ⚠ and this covers it without patching the ceiling.
• ⭐ The 390 mm body over a 330–350 mm hole gives a 20–30 mm overlap on each side — ⭐ enough to hide a rough or slightly oversized cut.
• ⚠ The figure that catches people is the DEPTH. ⭐ 200 mm of clear space is needed above the ceiling — ⚠ and in a bathroom with a low roof pitch, ducting, or a second storey above, that is not guaranteed. ⭐ Check it before ordering.
• ⭐ Measure the existing hole and the plenum depth, ⭐ tell us both, and we will confirm the fit.

⭐ Four functions on one ceiling point

• ⭐ Heat, light, exhaust and colour-switchable LED — ⭐ on a single aperture and a single point.
• ⭐ Which is the reason to choose a combination unit: ⚠ a bathroom ceiling has limited space and every separate fitting is another hole, another circuit and another thing to seal.
• ⭐ The lighting is 30 W with a switchable colour temperature (3000 K / 4000 K / 5000 K) and a published output of 850–950 lm.
• ⚠ 850–950 lm is bathroom-adequate rather than generous — ⭐ fine as the main light in a typical bathroom, and worth supplementing with a mirror light where someone shaves or applies makeup.

⭐ A 5-year warranty — longer than most of the catalogue

⭐ Domus publishes 5 years here. ⭐ Across the catalogue, 217 products record one year and 188 record three; ⭐ only 28 reach five. ⚠ The term is asterisked, and the conditions are not published on this product — ⭐ ask us for them in writing.

Where it works

• Retrofitting an existing three-in-one — ⭐ the 330–350 mm range covers most.
• Bathrooms and ensuites with 200 mm of plenum depth.
• Renovations avoiding ceiling patching — ⭐ the 390 mm body overlaps.
• ⚠ Not where plenum depth is under 200 mm — ⭐ check first.
• ⚠ Not as the only light where fine detail work happens — ⭐ add a mirror light.

Specifying it

4-in-1 retrofit bathroom heater — heat, light, exhaust and colour-switchable LED. 30 W lighting, 850–950 lm, 3000 / 4000 / 5000 K. Body 390 × 390 × 158 mm. Cutout 330–350 mm, 200 mm depth required. 240 V. 5-year warranty. ⭐ THE CUTOUT RANGE IS THE WHOLE QUESTION ON A RETROFIT — 330–350mm covers the hole most existing three-in-one units leave, and the 390mm body overlaps it by 20–30mm each side, so the ceiling does not need patching. ⚠ THE FIGURE THAT CATCHES PEOPLE IS THE DEPTH: 200mm of clear space is needed above the ceiling, and a low roof pitch or ducting may not allow it. Measure both and tell us.
