PHAM NEWS | MARCH 2025 Ventilation & Heat Recovery 33


MVHR saves on energy and freshens air


VRC is the name of Stiebel Eltron’s new range of ventilation systems, which focus on improving heat recovery and ensuring clean air circulation within buildings. The VRC can achieve up to 92% heat recovery, significantly enhancing a home’s ability to retain heat. The VRC range marks Stiebel


Eltron’s re-entry into the centralised mechanical ventilation with heat recovery (MVHR) market, complementing its existing decentralised systems. Designed for both residential and light commercial applications, the units can service spaces up to 425m2


. They feature a


detachable control panel that can be positioned up to 20m away from the main unit, allowing for versatile installation in various settings, including challenging spaces like roof areas or cupboards. Beyond winter heat retention,


the VRC systems are equipped with a heat exchanger bypass mode, which helps maintain comfortable indoor temperatures during warmer weather. The Enthalpy models include active


Quiet operation in the home


The Unity Range from Zehnder has been enhanced with the addition of two new decentralised Mechanical Extract Ventilation (dMEV) fans: the Unity CV2.1HT and the Unity CV2.A1PP. The new extract fans have been designed to meet the evolving needs of households for enhanced air quality and energy efficiency, providing sustainable, user- friendly ventilation solutions that are more in line with changing habits and lifestyles in residential properties. The Unity CV2.1HT operates


moisture control features to regulate humidity levels, thereby mitigating issues related to dampness and mould. The VRC units are user-friendly


and Wi-Fi enabled, enabling control through a dedicated smartphone app. This app also integrates seamlessly with existing Stiebel Eltron heat pump systems, allowing users to manage both devices from a single platform. In conjunction with the launch, the company is offering a complimentary service to size ventilation units and design integrated heat pump systems, aimed at simplifying the


installation process. “As consumers look to make


their homes as sustainable as possible, the new range will play an important role in delivering energy efficient buildings across the UK,” says Mark McManus, Stiebel Eltron MD. “For our installer partners we are offering great package deals when buying ventilation with heat pumps, including extending our generous heat pump warranty package to the ventilation units. Plus of course, there are benefits to having one point of contact for service and maintenance.” ◼ phamnews.co.uk/325/53


continuously at a low trickle rate and features an intelligent humidity sensor that adjusts based on real-time conditions. It is suitable for bathrooms and wet rooms and can be mounted in various locations. It also has an enhanced range of accessories, including a picture frame adaptor for when replacing larger fans, a window fixing kit for secure window installations and a fire collar for added safety in the event of a fire. The Unity CV2.1APP is tailored for rented or social housing,


offering an app that allows landlords to monitor fan performance and usage, facilitating better communication with tenants about mould prevention. Boasting all the functionality of the Unity CV2.1HT, including timer, humidity boost, precise airflow and tamper-proof settings, this fan also incorporates a ‘Do Not Disturb’ setting via the app, helping to not only reduce heat loss and energy wastage, but also tackling nuisance running at night. Both models include functions such as humidity boosts and memory


settings to retain configurations during power outages. ◼ phamnews.co.uk/325/54
