Industrial Hot Water Calorifiers, Storage Vessels, and Heating Systems
Calorifiers, hot water storage vessels, waste heat recovery equipment, and insulated piping systems designed and fabricated for industrial and commercial hot water applications
Key Highlights
Calorifier Design and Fabrication
britannia:jahco fabricates indirect water heaters (calorifiers) using steam coils, hot water coils, and U-tube copper tube bundles. Calorifier sizing covers the required duty, flow rate, inlet and outlet temperatures, and the conditions of the heating medium
Hot Water Storage Vessels
Storage vessels are sized to the temperature and volume requirements of the application and fabricated in stainless steel, duplex stainless or high nickel alloy construction. Vessels above the AS 1210 PV value threshold are designed and registered as pressure vessels
Waste Heat Recovery
Process waste heat from industrial refrigeration, compressed air systems, or other thermal plant can be recovered to pre-heat or heat water. britannia:jahco designs heat exchangers and calorifiers for waste heat recovery duties.
Insulation and Cladding
Storage vessels and piping are insulated to specification and clad in aluminium or anodised aluminium for indoor and export applications.
Code-Compliant Fabrication
Equipment is fabricated to AS/NZS 3500.4 and AS 1210 (where applicable). Britannia Jahco holds ISO 9001 certification through LRQA. Welding complies with AS 3992 and AS 1554.
Electric Immersion Elements
britannia:jahco fabricates storage vessels with fitted electric immersion elements for applications where steam or hot water heating is not available.
Why Choose Our Industrial Hot Water Services?
Industrial hot water systems require equipment sized to specific duty conditions: temperature, flow rate, heating medium, and legionella management requirements. AS/NZS 3500.4 requires storage temperatures of at least 60 degrees Celsius to prevent legionella growth, which sets a minimum performance threshold for every vessel and calorifier in the system.
britannia:jahco designs and fabricates custom equipment to those duty conditions rather than adapting standard product. Calorifiers are sized to the heating medium available -- steam, hot water, or electric element -- and vessel construction is matched to the water quality and operating environment. We fabricate for hospitals, hotels, food processing facilities, mining camps, and commercial HVAC plant.

Our Approach to Hot Water Services
Our highly experienced team focuses on:
Our Process
Consultation and Requirement Assessment
We review the heating duty, flow rates, temperature requirements, heating medium, and water quality to confirm the right equipment type and materials of construction.
Custom Design and Engineering
Calorifiers and storage vessels are sized to the specific duty conditions. Where AS 1210 registration is required, design documentation is prepared for submission to the relevant state authority.
Material Sourcing
Materials are sourced to ASTM and AS 1548 specifications. Options include carbon steel, stainless steel (304 and 316), and copper tube bundles. All materials carry certified material test reports (CMTRs).
Precision Fabrication and Assembly
Equipment is fabricated to AS/NZS 3500.4 and, where applicable, AS 1210. Insulation and cladding are applied to specification before dispatch
Testing and Quality Control
Hydrostatic pressure testing follows AS 4037. Performance against the design duty is verified before dispatch. Every unit ships with CMTRs and a full quality record.
Installation and Ongoing Support
We offer installation guidance and ongoing maintenance support to ensure long-term reliability.
Partner with britannia:jahco and experience the difference in performance, transparency, and client service.
Why Choose britannia:jahco?
britannia:jahco brings calorifier design, vessel fabrication, and code-compliance documentation together in one workshop at Dandenong South, Victoria. We hold ISO 9001 certification through LRQA and fabricate to AS/NZS 3500.4 and AS 1210.
Safety in Our Hot Water Services
Every hot water vessel is fabricated under a documented quality plan. Materials carry CMTRs with full heat number traceability. Storage vessels are designed to the AS/NZS 3500.4 temperature requirements that prevent legionella growth. Where vessels qualify as pressure vessels under AS 1210, design registration with the relevant state authority is managed as part of the project.
