PTC vs IXL “Bug Eye” Bathroom Heaters: Why Modern Bathroom Heating Has Moved On

For years, traditional IXL-style “bug eye” bathroom heaters were common in Australian homes. The familiar glowing infrared heat lamps provided quick warmth, but bathroom heating technology has moved forward. Modern PTC bathroom heaters now offer safer, more comfortable and more practical heating, often combining heating, lighting and exhaust into one sleek unit.

More Comfortable Heat Distribution

Traditional infrared heat lamps create intense radiant heat directly beneath the fitting. Stand underneath and you feel warm, but step away and the heat drops off quickly.

PTC, or Positive Temperature Coefficient, heaters use ceramic heating technology and a fan to circulate warm air around the room. Rather than creating one hot spot beneath the unit, they help warm the bathroom more evenly.

Whole Room Warmth Instead of Standing Under a Lamp

Old infrared systems heat people and surfaces directly. PTC systems actively move heated air through the room, helping reduce cold areas and making winter mornings more comfortable.

No Fragile Heat Globes to Replace

Older bug-eye systems rely on infrared heat globes, which eventually burn out and need replacing. PTC heaters remove this issue entirely. No heat globes means fewer consumable parts and less maintenance over time.

Improved Safety Features

Modern bathroom heaters often include safety improvements that older systems may not have. Many PTC models include automatic shut-off timers to help prevent the heater being left on for too long.

For example, the Domus ORBIS 4-In-1 Retrofit PTC Bathroom Heater includes a 2-hour safety cut-off, switching off the heating function if left running and requiring the user to turn it back on manually.

Designed for Easy IXL Replacement

One of the biggest concerns when upgrading an older bathroom heater is installation. Many modern retrofit PTC heaters are designed to replace common IXL-style units without major ceiling changes.

The Domus retrofit range includes the Domus ORBIS and Domus HEATCORE range, both designed as modern upgrade options for older bathroom heater installations.

More Than Just Heating

Modern PTC bathroom systems commonly combine multiple bathroom functions in one fitting, including:

• Heating
• LED lighting
• Exhaust extraction
• Tri-colour light switching
• Air circulation modes
• Digital wall controllers

The Domus ORBIS, for example, combines heating, extraction, air circulation and LED lighting into one retrofit unit.

A Smarter Bathroom Upgrade

The old infrared bug-eye heater served Australian homes well, but bathroom technology has moved on. Modern PTC systems provide more even heating, improved safety, lower maintenance and cleaner designs.

For homeowners replacing an ageing IXL unit, products such as the Domus ORBIS and Domus HEATCORE range show how bathroom heating has evolved from “stand under the heat lamp” to a more comfortable whole-room experience.
