As industries seek more efficient, scalable, and space-saving heating solutions, businesses are increasingly turning to decentralised gas-fired heating modules. Leading the way is the RHC+ Gas Fired Heat Module—a cutting-edge, ultra-low NOx heating solution engineered to replace aging steam and hot water systems and eliminate the need for central boiler plants.
From manufacturing plants and drying processes to air handling units in large commercial buildings, RHC+ delivers high-efficiency heating with the flexibility, ease of installation, and sustainability that modern businesses demand.
Let’s dive into why more companies are choosing RHC+ for their heating needs.
What is the RHC+ Gas Fired Heat Module?
The RHC+ is a fully packaged, gas-fired heating module designed for direct integration into air handling units (AHUs) or ductwork systems. Unlike traditional systems that rely on a central boiler plant, the RHC+ delivers heat exactly where it's needed, offering up to 109% net efficiency with ultra-low NOx emissions.
It features:
- A fully condensing 4-pass heat exchanger for compact, efficient heat transfer
- A pre-mixed blown gas burner with modulating capability for superior control
- A microprocessor controller for full operational and safety management
- Factory-assembled monobloc units up to 1000 kW, with stacking and cascade options for high-output needs
Whether you're replacing aging LPHW or electric coils or upgrading ductwork heating in an industrial process, the RHC+ delivers powerful, controlled, and eco-conscious performance.
1. Energy Efficiency & Cost Savings
At the heart of the RHC+ is an ultra-efficient burner and heat exchanger system that provides exceptional energy savings:
- Up to 109% nett efficiency, thanks to full condensation of flue gases
- 6:1 turndown ratio (up to 18:1 in monobloc units) for precise temperature control
- Reduced need for central boiler infrastructure, saving on installation, maintenance, and plant room space
- Integrated condensate drain to avoid performance loss due to moisture buildup
For businesses, this means lower operating costs, fewer energy losses, and consistent indoor climate control—all with minimal disruption.
2. Sustainable & Future-Ready Heating
With governments tightening environmental regulations and businesses prioritizing green initiatives, the RHC+ answers the call for more sustainable heating:
- Ultra-Low NOx burner to meet current and future emissions standards
- No central plant = lower energy distribution losses
- Compatible with decentralised energy strategies
- Ideal for replacing inefficient, high-emission systems like steam coils and electric heaters
By decentralising heating with RHC+, companies can make substantial progress toward their sustainability goals while ensuring regulatory compliance.
3. Flexibility for Industrial & Commercial Applications
RHC+ is engineered with industrial flexibility in mind. Its modular design fits a wide variety of applications:
- Air Handling Units – replaces steam or LPHW coils in both new and retrofit systems
- Ductwork Systems – integrates seamlessly, even in large-scale industrial buildings
- Process Applications – perfect for drying, curing, or other high-temp processes
With vertical, horizontal, and stacked configurations, plus a range of models from 30kW to 1000kW, RHC+ can be tailored to suit virtually any space or performance requirement.
4. Easy Installation & Minimal Maintenance
One of the biggest advantages of RHC+ is its plug-and-play design that simplifies both installation and long-term maintenance:
- Fully assembled on a slide-mount frame for AHU installation
- No pipework or frost protection required, minimising risk and cost
- Single-side access to burner and controls for streamlined servicing
- Optional weatherproof control vestibules for outdoor use
- UKCA and CE certified with on-site commissioning and national support
This means faster install times, reduced labour costs, and fewer disruptions—key benefits for high-output commercial environments.
5. Intelligent Controls & Integration
Control is critical in modern HVAC systems, and the RHC+ doesn’t disappoint. Businesses can manage their heating with:
- BMS compatibility via 0–10V DC signal for centralised control
- Microprocessor-based safety and operational management
- Optional control vestibules with custom finishes for outdoor or indoor applications
Whether you're integrating with an existing building management system or starting fresh, RHC+ provides reliable, responsive control tailored to your facility.
