Multi-Residential Hot Water in Woodlands, WA
Future-Proof Hot Water for Luxury Apartments
Location: Woodlands, WA
Sector: Multi-Residential
Products: HF-318 & HF-327 3-Phase Instantaneous Water Heaters (50°C limited)
The Challenge
A new boutique multi-residential development in a northern suburb of Perth required a reliable and energy-efficient hot water system to service seven luxury apartments. Bromic was briefed to deliver a compact system that would ensure reliable hot water performance during peak usage periods across multiple dwellings, while adhering to strict safety and compliance requirements. Meeting the Built Environment Sector Plan (part of the Net Zero plan) meant eliminating reliance on gas infrastructure and reducing whole-of-life maintenance demands – effectively future-proofing the development.
Our Solution
Bromic’s HF-318 and HF-327 3-Phase Instantaneous Electric Water Heaters provided a compact, tankless solution that met the project’s space and efficiency needs. These units heat water only as needed, eliminating standby energy losses and minimising water wastage and dead legs, improving the efficiency of the entire building.
WaterMarked certified to AS/NZS 3498 (WM 40268), the units deliver compliance peace of mind, and safe and consistent hot water delivery. Built-in overcurrent and overload protection safeguards internal components and ensures safe operation.
Instant hot water performance scales with inlet temperature and demand requirements, with electronic temperature control ensuring consistent delivery. Pre-set to 50°C, the units provide resident-safe hot water without the need for a separate tempering valve, reducing installation costs and complexity.
The efficient decentralised design simplified maintenance with no tanks to corrode, no Legionella risk and no complex monitoring requirements. Individual units can be serviced or replaced without impacting supply to the entire building, supporting reliability and lower lifecycle costs.
Products specified:
- 4 × HF-318 (2850318-S50) – 18kW, 3-Phase Instantaneous Electric Water Heater
- 3 × HF-327 (2850327-S50) – 27kW, 3-Phase Instantaneous Electric Water Heater
Outcomes & Benefits
Simplified Installation & Design
The wall mounted fully electric, tankless design has removed the need for gas infrastructure, flues, or bulky storage tanks streamlining installation and freeing up valuable floor space for apartments and amenities.
Energy Efficiency
Heating on demand eliminates standby losses and minimises wasted cold water at outlets. Energy use is now lowered, bringing significant cost savings to the building.
Safe & Compliant
Pre-set 50 °C units with electronic temperature controls are certified to AS/NZS 3498 and installed in accordance with AS/NZS 3500, providing consistent, safe hot water delivery across all apartment fixtures.
Low Maintenance & Reliable
Without having to worry about storage tanks that can corrode or accumulate sediment, any risk of leaks, Legionella growth, or system-wide downtime has been eliminated. The decentralised solution has allowed individual apartments to be serviced or replaced without interrupting hot water across the entire development.
Future Proof
Compact, efficient, and fully electric, the solution is aligned with the industry’s shift away from gas, providing a sustainable and regulation-ready option for multi-residential projects.

Hot Water FAQs
Yes. Electrical diversity is used when multiple 3-phase EHW units are installed on the same project. Since not all hot water units operate at once, this allows for more accurate electrical load calculations and can significantly reduce the size and cost of wiring, cabling and switchboards.
By heating water only when needed, Bromic 3-Phase Instantaneous water heaters eliminate standby losses and reduce wasted cold water. This results in lower energy consumption and reduced running costs for the building.
For example, the units installed in the Woodlands WA project were WaterMarked to AS/NZS 3498 and installed in accordance with AS/NZS 3500. Each unit features electronic temperature control pre-set to 50°C, meeting safety requirements without requiring a separate tempering valve.
Without central storage tanks, there is no risk of Legionella growth, corrosion, or sediment build-up. There is also no need for ongoing monitoring. Individual units can be serviced or replaced without interrupting hot water supply to other parts of the building.
Yes. The HF-318 and HF-327 3-Phase Instantaneous Electric Water units used in this project can be configured to meet a wide range of hot water demands in a variety of developments, including multi-dwelling and commercial buildings, as well as any applications requiring consistent, efficient hot water supply.
