Specifying The Right Bathroom Heater For Every Project
Choosing the right bathroom heater comes down to matching heat output, exhaust capacity and IP rating to the room, then knowing which range in the Domus line-up fits the project's budget and feature requirements. The sections below walk through how to size a heater for the application, then how the Signature, Select and Retrofit ranges compare across a project.
Choosing The Right Heater For The Application
Not every bathroom calls for the same bathroom heater. A compact ensuite with limited extraction needs may be well served by a straightforward heat lamp, while a larger family bathroom with poor natural ventilation benefits from a higher-capacity exhaust fan or combined light unit. When specifying for a project, compare heat output, exhaust capacity and IP rating side by side, since these three figures determine whether a model can heat the room fast enough, clear steam and condensation effectively, and handle the bathroom’s moisture exposure safely.
For projects where budget allows for the full feature set, including digital control, whisper-quiet operation and the fastest heat-up times, the Signature Range is built to deliver premium performance without compromise. It’s the specification of choice where clients want a bathroom warming lamp that performs as well as it looks.
Specifying The Wider Bathroom Heater Range
Every Domus bathroom heater is designed to work as part of a coordinated range, so specifiers and builders can standardise on one system across multiple projects rather than mixing brands and control types. If the Signature Range’s premium features are more than a project calls for, the Select Range delivers the same core heating and ventilation performance in a more cost-effective bathroom heater light, ideal for standard spec builds and multi-unit developments.
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. Across all three ranges, Domus bathroom heaters 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.
