Combining energy effi ciency with aesthetic appeal


The new Zeno R290 air source heat pump from Warmflow is said to combine advanced technology with user-friendly features and aesthetic appeal. The unit delivers up to 5kW of heat for


every 1kW of electricity consumed, thereby reducing energy costs for homeowners and aligning with global initiatives for carbon reduction. It uses eco-friendly R290 refrigerant and


features a compact design, which means it can fit seamlessly into a variety of spaces, making it an ideal choice for both new builds and retrofitting existing systems. A stylish anthracite grey finish has been designed to match modern windows and doors and should ensure that the heat pump will integrate with any property’s aesthetic. The Zeno R290 also uses Warmflow’s


Warmlink Wireless Control Technology, which enables heating engineers to manage installations wirelessly through their smartphone or tablet. This not only enhances the commissioning process but also provides remote diagnostics capabilities to assist with maintenance and troubleshooting without having to attend on site. For ease of installation, the heat pump


is equipped with a full-colour touchscreen which allows for easy on-site adjustments


Building on the success of its award winning S735 exhaust air heat pump, NIBE has launched the S735C unit – an intelligent inverter-controlled exhaust air heat pump with an integrated water heater, providing heating, cooling, hot water and ventilation effi ciently and economically. With active cooling built in, the S735C is capable


of keeping the indoor temperature down during the hot summer period, and will also assist with Part O compliance. The heat pump uses R290 refrigerant and is able to deliver further energy savings by automatically adapting to a dwelling’s heating demands. NIBE says that a low noise level, a stylish design with a


and settings management. The intuitive controls allow for two levels of access: one for the homeowner and the other for the heating engineer.


Free back-up support For installers working on their first installation, Warmflow offers a free assisted setup service, providing access to expert guidance during the installation process and helping to ensure a successful result. The company is also happy to provide a free design service: Warmflow offers a complimentary design service for specifying the Zeno R290 and its Nero heat pump cylinders. Free product training for installers and


MCS assisted sign-off is also available. For end-users looking to take advantage of the government’s grant funding, Warmflow will help to coordinate the required paperwork and approval. ◼ phamnews.co.uk/325/39


touchscreen controller, and compact size make it perfect for smaller modern properties, while the addition of the NIBE SAM S42 supply air module gives an option for when balanced exhaust and supply air ventilation is required. ◼ phamnews.co.uk/325/40


Controls for a quicker installation


Designed to make heat pump installations quicker and easier, the Adia Thermal is a smart controls system that promises to improve the performance of existing radiators and pipework. The system operates with fl ow regulators which help to monitor the operation of radiators and measure room by room heat loss, thereby providing valuable insights into system effi ciency. The company claims that the patent-pending solution will enable installers to complete a heat pump installation in just three days. ◼ phamnews.co.uk/325/41
