EV PREMIUM OR EV PREMIUM+ (PLUS)?
When it comes to home ventilation, RenewAire has long been a leader in Energy Recovery Ventilators (ERVs). Their latest evolution, the RenewAire EV Premium Series and the EV Premium+ (Plus), sets a new standard for indoor air quality (IAQ) and energy efficiency.
But which one is right for your project? Below, we break down the key differences to help you choose between these two high-performance systems.
At a Glance: RenewAire EV Premium vs. EV Premium+
While both series share the same legendary G5 static-plate core and high-efficiency EC motors, the "Plus" series is designed specifically to meet the most stringent new energy codes (like California’s Title 24 2025) and offers "smart" commissioning features.
| Feature | EV Premium Series | EV Premium+ (Plus) Series |
| Core Technology | 5th Gen (G5) Cellulosic Core | 5th Gen (G5) Cellulosic Core |
| Airflow Control | Manual Dial-A-Flow | Constant Volume (Logic-controlled) |
| Setup Tool | Onboard Dials | Touchscreen Control+ (TC1+) |
| Code Compliance | IECC, HVI, ETL | CEC Title 24 (FID Compliant) |
| Smart Monitoring | Standard LED Status | Filter & Fault Indicator Display (FID) |
| Application | Residential / Light Commercial | Residential / Multi-Family / Strict Code |
1. Precision Control: Dial-A-Flow vs. Constant Volume
The most significant technical difference lies in how the units manage airflow.
- RenewAire EV Premium: Uses the intuitive Dial-A-Flow system. This allows installers to manually adjust the fan speeds to balance the home’s ventilation during the initial setup. It is simple, reliable, and perfect for standard residential installs.
- RenewAire EV Premium+: Features Constant Volume logic. Once you set your desired CFM (in 5 CFM increments), the unit’s smart sensors automatically adjust the fan speed to maintain that exact airflow, even if filters get dirty or external static pressure changes.
2. The Touchscreen Advantage
If you love tech-forward solutions, the EV Premium+ is the clear winner.
- Touchscreen Control+ (TC1+): While the standard Premium series relies on manual dials, the Plus series utilizes the TC1+ accessory. This 4-inch color touchscreen provides a step-by-step installation guide, displays real-time CFM and power usage, and acts as a central hub for system diagnostics.
- Contractor Tip: For professionals, the TC1+ is a "reusable" tool—you can use one controller to set up multiple ERVs, saving money on equipment costs for multi-unit projects.
3. Code Compliance and "The Plus"
The "Plus" in the name refers largely to its readiness for the future of building codes.
- California Title 24: The EV Premium+ is fully compliant with 2025 Fault Indicator Display (FID) requirements. It can alert homeowners to low airflow or sensor errors directly on the wall-mounted screen.
- IECC 2024: The Plus series is engineered to meet the latest International Energy Conservation Code mandates for latent recovery and power consumption, often reaching an incredible 10 CFM per watt.
4. Shared Excellence
Regardless of which model you choose, you are getting RenewAire’s best-in-class features:
- No Condensate Drain Needed: Unlike HRVs, these ERVs don't require a drain line, making them much easier to install in any orientation (attics, closets, or basements).
- MERV 13 Capability: Both series can be upgraded with MERV 13 filtration to capture allergens, smoke, and fine particulate matter.
- Static-Plate Core: The G5 core keeps airstreams separate, ensuring fresh air enters your home while stale air and pollutants are exhausted.
Which Should You Buy?
- Choose the RenewAire EV Premium if: You want a cost-effective, high-efficiency ERV that is easy to install and maintain without the need for advanced digital interfaces. It’s the "Gold Standard" for most single-family homes.
- Choose the RenewAire EV Premium+ if: You are building in a state with strict energy codes (like California), you want the "set it and forget it" peace of mind of constant volume airflow, or you prefer a digital touchscreen interface to monitor your home's air quality.
