Replacing an Old Bathroom Tastic? Meet the Domus ORBIS 4-in-1 Retrofit Bathroom Heater

Written By Scott Spragge

If your bathroom heater is outdated, noisy, or no longer keeping the room warm, replacing it can make a big difference to your comfort — especially during Melbourne’s cooler months. The Domus ORBIS 4-in-1 Retrofit Bathroom Heater is designed to replace many older 2-heat and 4-heat infrared bathroom heaters with minimal ceiling modification.

At Vibrant Electrical, we install modern bathroom heating and ventilation solutions for homes across Pakenham and Melbourne’s south-east. The ORBIS is a great option for homeowners who want to upgrade their bathroom without a major renovation.

What Is the Domus ORBIS?

The Domus ORBIS is a 4-in-1 bathroom heater that combines heating, lighting, and ventilation in one ceiling unit. It uses modern PTC heating technology and is specifically designed as a retrofit solution for older bathroom heater units.

Rather than needing a large new ceiling opening, the ORBIS is compatible with many existing 2-heat and 4-heat infrared models, making it a practical upgrade for bathrooms with an older Tastic-style unit.

Key Features of the ORBIS Bathroom Heater

The ORBIS includes several features that make it a strong choice for a bathroom upgrade:

  • 2250W PTC heating element for fast, efficient bathroom warmth

  • Tri-colour switchable LED light — choose 3000K warm, 4000K neutral, or 5000K cool lighting

  • Integrated exhaust fan with 300m³/h air extraction to help remove steam and moisture

  • Digital wall controller for simple, one-touch operation

  • Automatic two-hour shut-off for added safety and peace of mind

  • Retrofit design that suits many existing 2-heat and 4-heat infrared bathroom heaters

  • 330 x 350mm cutout size, which can reduce the need for major ceiling changes

Why Replace an Old Bathroom Tastic?

Older bathroom heaters can become less effective over time. Common signs that it may be time for an upgrade include:

  • The bathroom takes a long time to warm up

  • The heat lamps no longer provide enough warmth

  • The fan is noisy or no longer clears steam effectively

  • The light is dim, flickering, or outdated

  • The unit looks tired or no longer suits your bathroom

  • You want a safer, more modern solution with better controls

A modern 4-in-1 unit can improve comfort, lighting, and ventilation in one installation — instead of relying on separate heaters, fans, and lights.

PTC Heating: A Modern Alternative to Heat Lamps

Many older bathroom heaters use infrared heat lamps. The ORBIS instead uses a PTC heating element, a modern heating technology designed to provide consistent warmth.

PTC stands for Positive Temperature Coefficient. In simple terms, the heating element is designed to regulate its temperature as it heats up, which supports safer and more controlled operation compared with older-style heat lamps.

For homeowners, this means a bathroom heater that is designed for modern, everyday use — with the added reassurance of an automatic two-hour shut-off.

Better Lighting and Ventilation in One Unit

One of the biggest benefits of the ORBIS is that it does more than heat the room.

The built-in 12W tri-colour LED light lets you select the lighting tone that suits the moment:

  • 3000K warm white for a relaxed, comfortable feel

  • 4000K neutral white for everyday bathroom use

  • 5000K cool white for brighter, clearer task lighting

The integrated exhaust fan also helps remove steam and moisture after showers, which can help reduce foggy mirrors and support a fresher, drier bathroom environment.

Is the ORBIS Suitable for Your Bathroom?

The ORBIS is designed as a retrofit replacement for many existing 2-heat and 4-heat infrared bathroom heaters. Its cutout size is 330 x 350mm, so suitability will depend on the size and condition of your existing ceiling opening, the available space above the ceiling, and your bathroom’s electrical setup.

That’s why professional assessment and installation are important. At Vibrant Electrical, we can inspect your existing bathroom heater, confirm whether the ORBIS is compatible, and install it safely and neatly.

Professional Bathroom Heater Installation in Pakenham

Replacing a bathroom heater involves more than swapping a ceiling unit. It may require safe disconnection of the old unit, checking wiring and ventilation, installing the new heater, setting up the wall controller, and testing every function.
