Understanding the DVS EC Reclaim Connect Heat Recovery Ventilation System

Understanding the DVS EC Reclaim Connect Heat Recovery Ventilation System

1. What is the DVS EC Reclaim Connect?

The DVS EC Reclaim Connect represents a practical and versatile option in the realm of balanced pressure heat recovery ventilation (HRV) technology, offering a solid solution for residential air quality management. Differing from traditional HRV systems that are usually integrated within a home's thermal envelope, this system is uniquely designed for installation outside the thermal envelope, either in a roof cavity or an underfloor subfloor space. This alternative approach to installation makes it a more suitable choice for the everyday homeowner, particularly when considering budget and ease of retrofitting in a variety of home types.

An HRV system, at its core, is designed to foster a healthier living environment. It operates by exchanging the stale, indoor air with fresh, outdoor air, while conservatively retaining the energy used in heating or cooling the home. This balance of fresh air intake and energy efficiency is crucial in maintaining a comfortable, healthy indoor environment, particularly in diverse Australian climates.

2. Advantages of the DVS EC Reclaim Connect


The DVS EC Reclaim Connect is a cost-efficient solution compared to its counterparts. When installed, it's about half the price of an equivalent STIEBEL ELTRON system and considerably more affordable than Zehnder models. This price advantage makes it an accessible option for a wider range of homeowners.

Superior Airflow

Boasting an airflow capacity of up to 475 cubic metres per hour, the DVS EC Reclaim Connect stands out for its ability to efficiently cater to homes that may not be as well sealed as newly built homes that allowed for ventilation inside the thermal envelope at the time of building. This high airflow capacity is particularly advantageous in such environments, as it ensures a more effective exchange of air, critical in maintaining healthy indoor air quality. For larger homes or those with areas that have higher air quality demands, the system's superior airflow can effectively counterbalance the challenges posed by less airtight structures. This makes the DVS EC Reclaim Connect an ideal solution for a wide range of homes, ensuring that even those with less optimal sealing can enjoy the benefits of clean, fresh air circulated throughout their living spaces.

Ease of Installation and Retrofit

The system's design for installation outside the thermal envelope significantly reduces the complexity and time involved in the installation process, typically allowing for completion within a single day. This aspect is particularly beneficial for retrofitting in existing homes, which is a challenge for systems designed for integration during the building process.

DVS EC Reclaim Connect

Advanced Filtration

It offers comprehensive whole-home MERV15 filtration using natural wool and charcoal. This level of filtration is adept at removing airborne particles, allergens, and odours (such as bushfire smoke), thus significantly improving indoor air quality.

Versatility and Smart Features

This system is suitable for almost any Australian home that has a roof cavity or subfloor space. Its smart features, including a WiFi-connected controller and custom programming, offer user-friendly operation and adaptability to individual preferences and needs.

Energy Efficient EC Motors by ebm-papst

One of the standout features of the DVS EC Reclaim Connect is the inclusion of energy-efficient EC motors by ebm-papst. These motors are renowned for their superior efficiency and performance, significantly contributing to the overall energy efficiency of the system. Electronically Commutated (EC) motors are designed to use electricity more effectively, reducing power consumption while maintaining even higher airflow than their AC counterparts. This is particularly beneficial for homeowners looking to minimise their energy usage and environmental footprint, without compromising on ventilation quality. The integration of ebm-papst EC motors into the DVS EC Reclaim Connect system exemplifies a commitment to combining advanced technology with environmental responsibility, making it an excellent choice for those seeking an energy-efficient ventilation solution.

3. Disadvantages of the DVS EC Reclaim Connect

Slightly Reduced Efficiency

Its external installation can impact its efficiency in heat recovery. Nonetheless, this can be effectively countered with the use of quality Australian made insulated ducting, designed to preserve the temperature of air being transported.

Balancing Challenges

The single duct network per side (supply and exhaust) may present some balancing challenges compared to systems with separate pipes for each diffuser. However, with skilled installation and the strategic use of dampers, these issues can be effectively managed.

Suitability Concerns

For modern homes that lack the necessary space for the installation of a centralised system like the DVS EC Reclaim Connect, it might not be the most suitable option. This is particularly relevant for contemporary homes designed without provisions for centralised ventilation systems at the time of building. In such cases, homeowners need not compromise on the quality of their indoor air. We offer a range of decentralised ventilation options that are specifically tailored for these scenarios. Decentralised systems provide flexibility and can be adapted to the unique structural and spatial constraints of modern homes. If you find yourself in this situation, we encourage you to reach out to us. Our team can help you explore these decentralised ventilation solutions, ensuring that you can still achieve optimal air quality and ventilation efficiency, even in a modern home that wasn't initially designed with centralised ventilation in mind.

4. Why Install a DVS EC Reclaim Connect?

Comprehensive Indoor Air Quality Improvement

Installing the DVS EC Reclaim Connect brings a multitude of benefits, foremost being the enhancement of indoor air quality. With its high-efficiency filtration system, it significantly reduces indoor pollutants, allergens, and odours, contributing to a healthier living environment.

Effective Humidity Management and Condensation Control

Another key advantage is its capability in managing home humidity levels and controlling condensation. This is particularly crucial in areas with high humidity or during colder months when indoor condensation is a common issue. By maintaining optimal humidity levels, it helps prevent mould growth and structural dampness, thereby safeguarding the home’s integrity and the occupants’ health.

Energy Efficiency and Cost Savings

Despite its slightly lower heat recovery efficiency, the system remains energy-efficient. By conserving the energy used in heating or cooling the home, it can lead to significant cost savings in the long term, especially in regions with extreme weather conditions.

Flexibility and Customisation

Its adaptability to various home structures, coupled with its smart technology features, allows for a customised approach to home ventilation. Homeowners can tailor the system's operation to their specific needs, enhancing comfort and convenience.


The DVS EC Reclaim Connect emerges as a robust and versatile solution in the realm of balanced pressure heat recovery ventilation systems. Its combination of affordability, high airflow capacity, advanced filtration, and ease of installation makes it an attractive option for many Australian homeowners. While it has its drawbacks, such as slightly reduced heat recovery efficiency, its overall benefits in improving indoor air quality, managing humidity, and offering customisable features far outweigh these limitations. For those seeking a comprehensive ventilation solution that balances cost, efficiency, and adaptability, the DVS EC Reclaim Connect is undoubtedly a worthy consideration.
