When renovating an existing home or commercial space, challenges are often more complex than in new construction. Space constraints, outdated infrastructure, budget limitations, and the presence of current occupants make it difficult to adopt conventional HVAC solutions. In these contexts, modular HVAC systems—those designed for flexible, phased deployment—emerge as the ideal solution.
Traditional HVAC systems usually involve centralized air conditioning or heating systems that require significant structural modifications. This not only increases cost but can also disrupt day-to-day life, especially if the building is occupied. Modular HVAC systems, on the other hand, offer components that can function independently or together, allowing you to modernize your comfort infrastructure step by step.
Why Renovation Projects Need Modular Thinking
In retrofit projects, there is often no “one-size-fits-all” approach. The structural complexity of older buildings makes it hard to fit large air ducts or central units. In these cases, it is not practical—or economical—to tear down walls or ceilings just to install a single comfort system. Moreover, many renovations are carried out while people still live or work in the space, making noise and dust a major concern.
Modular systems solve these issues by being inherently scalable. You can upgrade a single room with electric underfloor heating this year and add fresh air ventilation to another zone next year. With smart controls, even phased systems feel unified. This flexibility makes modular HVAC not only technically suitable but also economically viable.
What Is a Modular HVAC System?
A modular HVAC system is a decentralized approach that breaks down the comfort infrastructure into specialized but interoperable units. These may include:
- Heating Modules: Underfloor heating using electric cables or hydronic PE-Xa pipes
- Ventilation Modules: Fresh air units like the Menred G3 or G4, featuring energy recovery and IAQ sensors
- Control Modules: Smart thermostats (e.g., RT51/RT52) that support zoning and remote access
- Integration Modules: Interfaces for expansion into energy storage, solar systems, or building automation
Each unit can operate independently but is designed to work best in sync with others. This makes it perfect for step-by-step renovation projects.
Menred’s Modular HVAC Solutions
Heating Module: Menred offers both electric underfloor heating cables, which require no trenching, and hydronic systems using PE-Xa pipes. These systems are managed by programmable thermostats (RT51/RT52), allowing homeowners to enjoy zoned, energy-efficient comfort. Ideal for bathroom or kitchen retrofits where space is limited and traditional radiators aren’t suitable.
Ventilation Module: Menred’s G3, G4, and IEC models provide high-efficiency energy recovery (up to 75%) and ultra-quiet operation (as low as 29 dB). These systems are equipped with real-time CO2 and PM2.5 sensors, ensuring healthy indoor air even in sealed environments. Since they function independently from the air conditioning system, they can be installed during any stage of a renovation.
Control Module: Menred smart thermostats and panels unify all systems into a user-friendly interface. Whether accessed via wall-mounted panels or a mobile app, users can monitor and adjust each room’s climate. The system supports Modbus and RS485 protocols, making it future-proof and compatible with smart home or building automation platforms.
Application Scenarios
Modular HVAC is highly adaptable and suitable for a wide range of renovation cases:
- Residential Apartments: Where retrofitting full central air systems is too invasive
- Loft and Attic Conversions: Where ducting and equipment access is limited
- Clinics and Small Offices: Needing targeted comfort upgrades without interrupting operations
- Heritage or Older Buildings: Where regulations restrict structural modifications
- Partial Upgrades: Like only updating bathroom heating or adding a ventilation unit to the living area
Conclusion: Start Small, Think Big
Renovation doesn’t always have to be a massive, disruptive process. With Menred HVAC’s modular solutions, you can gradually transform any space into a smart, efficient, and healthy environment. The flexibility of component-based design empowers homeowners, architects, and builders to tailor systems to actual needs and budgets.
Whether you’re upgrading one room or planning a full-system overhaul, Menred provides the modular tools to make every stage of renovation smarter.
