VOKÈRA BY RIELLO LAUNCHES ALL NEW VISION PLUS RANGE
Vokèra by Riello has launched the all new Vision Plus condensing boiler range. Vision Plus adds to the features and benefits of its predecessor – including new stainless steel heat exchanger technology on selected models – to offer high flexibility in performance and installation for a wide variety of domestic applications. Vokèra, through its parent company Riello Group, is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.
The new range includes a choice of seven boilers: four combination boilers with outputs of 25 – 40kW and three system boilers with outputs of 20 – 30kW, all with a standard seven-year warranty. Featuring a click-fit flue system for easy installation across the range, and combination models with a universal pipe connection layout, the new Vision Plus is a great choice for installers and homeowners alike.
Vision Plus combines Vokèra’s extensive knowledge of boiler design and performance in an innovative, installer-friendly range that offers Class A energy efficiency in accordance with the Energy Related Product (ErP) Directive. All models are feature-packed to deliver energy-saving comfort and long-term reliability and have the OpenTherm controls protocol embedded.
As a further innovation, the 35kW and 40kW combination boilers and all three system boilers in the Vision Plus range feature a new, optimised radial stainless steel heat exchanger, which enables a wide modulation ratio of 1:8 for optimum operating efficiency and flexibility. This means that the Vision Plus 40C combi, for example, can modulate down to 4.9kW and the 35C down to just 4.4kW. This ensures that boiler cycling is reduced even when the central heating load is minimal. Ideal for larger homes, the 40C delivers an excellent domestic hot water rate (DHW) of 16.4 litres per minute at ΔT 35 C, while the 35C has an equally impressive DHW rate of 14.2 litres per minute at ΔT 35 C.
The 25C and 30C combination models use a proven aluminium heat exchanger, offering high thermal conductivity and combining the benefits of a lightweight, compact design. These models have small installation footprints and the rear flue option makes it easy to fit these compact appliances into small spaces, such as kitchen cupboards. They are also lightweight for easy handling and transportation.
All Vision Plus combination boilers have a built-in filling loop and include an embedded seven-day time clock with three modes of operation and back-lit LCD display for energy-saving comfort and control of heating times throughout the week. The universal pipe connection layout on all combination models also makes it easier when replacing another boiler with Vision Plus.
The system heat-only Vision Plus boilers can provide central heating, be matched with Vokèra AquaFlow unvented cylinders to provide domestic hot water storage, and be connected to any existing S-Plan or Y-Plan system. A wide modulation ratio ensures flexibility and efficiency and, thanks to the Modbus protocol, the entire Vision Plus range is designed to be ‘hybrid ready’ for integration into low carbon heating system designs. For further flexibility, all system models boast a built-in relay, which allows for easy integration with zone valves.
