The Domus Signature Range is built for projects where budget allows for the full feature set: digital control, whisper-quiet operation and the fastest heat-up times in the Domus bathroom heater line-up. Specifiers and builders can rely on it wherever a client wants a bathroom heater that performs as well as it looks.
Specifying The Signature Range For Your Project
Choosing the right Signature Range model comes down to matching heat output and exhaust capacity to the room first, since digital control and whisper-quiet operation are already consistent across every model in the line-up. The sections below walk through sizing a unit for the application, then how the Signature Range compares against the rest of the Domus bathroom heater line-up.
Heat Output, Exhaust Capacity And IP Rating
Specifying a Signature Range model starts with matching heat output to the room. A larger family bathroom with poor natural ventilation needs a higher heat output and exhaust capacity than a compact ensuite, so compare both figures against the room’s volume rather than choosing on finish alone. Exhaust capacity also determines how quickly the unit clears steam and condensation after a shower, which matters more in bathrooms with limited windows or extraction. IP rating protects the electronics from the bathroom’s moisture exposure, and the Signature Range is built to handle that environment across every model in the line-up. Digital control and whisper-quiet operation are consistent across the range, so the main decision for a specifier is sizing the heat output and exhaust capacity correctly for the room, not choosing between feature levels. Where a project’s budget calls for a more cost-effective option instead, the Select Range delivers the same core heating and ventilation performance.
Comparing The Full Domus Heater Range
The Signature Range sits at the top of the Domus bathroom heater line-up, but not every project or budget calls for its full feature set. For standard spec builds and multi-unit developments where cost-effectiveness matters more than premium features, the Select Range delivers the same core heating and ventilation performance in a more affordable bathroom heater light. For renovation work, the Retrofit Range is purpose-built to replace ageing 3-in-1 infrared units without cutting a new ceiling opening, keeping install time and cost down. Comparing all three ranges against the project brief, rather than defaulting to one range across every job, helps match the right level of feature and cost to each bathroom. All three ranges are backed by a 5-year in-home warranty and stocked through the Domus Partner trade network, so pricing and availability are a call away for trade and project accounts.
Frequently asked questions
Yes! The digital wall controller emits an audible beep by default whenever a button is pressed to confirm mode selection. If you prefer silent operation, simply press and hold the Standby button for 3 seconds. This will toggle the button-press beep sound on or off.
For maximum comfort and steam control, follow our recommended 3-Step Operation Process: Pre-heat the Room (5 Minutes): Turn on the HEAT function for up to 5 minutes before stepping into the shower. Pre-warming the air and cold wall surfaces significantly reduces condensation formation before steam even starts. Run the Exhaust After Showering: Keep the exhaust running for a few minutes after you finish showering to completely clear lingering humidity. Maintain Cross-Ventilation Placement: Ensure your unit is installed away from corners and positioned between the door (fresh air inlet) and the shower (steam source).
Keep your windows closed for optimal extraction. Counterintuitively, keeping the bathroom window closed produces the best steam removal. Controlled Airflow: Closing the window forces the fan to pull drier air from the rest of the home (usually through the clearance gap under the bathroom door). This sweeps across the whole room, drawing steam away from the shower and straight out the exhaust. Prevents Short-Cycling: If a window right next to the fan is open, the fan will simply pull outside air straight from the window and push it back out, leaving the rest of the room humid and foggy. The Exception: If your bathroom door is completely airtight with zero gap at the bottom, crack the window open slightly so the fan has an air intake source.
No. A single digital wall controller can only be paired with one individual ceiling unit. Because these high-performance units pull up to 2250W each, attempting to bridge multiple heaters onto a single digital control system will severely overload the wall plate circuitry and create an immediate electrical hazard.
Your licensed electrician will follow the detailed schematics supplied inside the unit packaging. Incoming 240V AC mains power connects directly to the main terminal block on the ceiling chassis. The digital wall controller connects to the main unit via dedicated communication wiring. If you choose to utilise the AUX feature for additional lights or a standalone secondary exhaust fan, your electrician will terminate those secondary connections into the available auxiliary terminal inside the main terminal enclosure.
No. The unit's electronic control module is engineered to receive input data from a single master digital controller. Attempting to wire two digital plates together in a 2-way configuration will cause communication bus errors, preventing the unit from turning on.
