Steam & Hot Water Systems

Industrial Boilers for Reliable Process & Building Heat

A boiler is a closed vessel used to heat water and generate steam or hot water for industrial and commercial applications—from space heating and process steam to power generation and sterilisation.

iEngineering supports boiler deployments for food processing, chemical plants, sugar mills, textile facilities, healthcare, paper mills and FMCG industries across Australia, Fiji, India and the Pacific.

Typical steam boiler installation

Flexible Integration

Support for low, medium and high-pressure boiler systems, burners, pumps, controls and safety devices tailored to your process.

Boiler classification

Boiler Types & Operating Characteristics

Boilers are classified by gas and water flow paths, circulation method, operating pressure, orientation and application. We align these technical characteristics to your thermal demand and process.

Flow path

Water-Tube Boilers

Water flows inside tubes while hot gases pass over them. Suitable for higher pressures and larger steam capacities—used in power plants, refineries and major process industries.

High pressure Large capacity

Flow path

Fire-Tube Boilers

Hot gases flow through tubes immersed in water. Compact and robust, they are ideal for low and medium-pressure steam and hot water in food, textile, healthcare and commercial buildings.

Compact Low/medium pressure

Energy source

Electric Boilers

Use electrical energy to generate steam or hot water. A clean option where flue emissions are restricted, or where electricity tariffs favour electric heating for smaller loads.

Zero on-site emissions Quiet operation

Pressure

Low, Medium & High-Pressure

Solutions for low-pressure heating systems, medium-pressure process steam and high-pressure or supercritical units for power generation and demanding industrial duties.

Heating & process Power generation

Circulation

Natural & Forced Circulation

Both buoyancy-driven (natural) and pump-driven (forced) circulation boilers are deployed based on height, layout, pressure requirements and response time.

Stable operation Process responsive

Application

Stationary, Portable & Marine

Stationary plant boilers, portable units for temporary or remote sites, locomotive and marine boilers, configured with the right mounting, orientation and controls.

Site-specific Flexible deployment

How we work

Boiler Project Workflow

We follow a structured approach—from load assessment and type selection through to supply coordination and commissioning support—so your boiler installation is safe, efficient and compliant.

Our team can work with your consultants, mechanical contractors and facility team to integrate boilers into existing plant rooms, new builds or retrofit projects.

1

Thermal Load & Site Assessment

Review of process or building heating demand, operating pressure and temperature, duty cycles, available utilities, fuel options and installation constraints.
2

Boiler Type & Configuration Selection

Selection of water-tube, fire-tube or electric boiler; flow path, circulation method, pressure class and orientation to match performance and regulatory needs.
3

Engineering & Supply Coordination

Coordination with manufacturers for boiler packages, burners, pumps, feedwater systems, valves and controls—including documentation, QA and logistics.
4

Commissioning Support & Ongoing Optimisation

Support for commissioning, performance checks and safety interlocks, followed by ongoing guidance on efficiency improvements and lifecycle upgrades.
