To ensure we're always innovating we use our knowledge of the harsh Nordic climate to test all our new ideas until we have developed the most optimal solution to the problem we're trying to solve.
NIBE S2125 is an intelligent inverter controlled air / water heat pump. With NIBE indoor modules, it forms a highly efficient climate system for your home. The heat pumpoperates with a natural refrigerant for a sustainable impacton the climate and the environment. It provides optimizedsavings because it automatically adapts to thehome's power needs.
NIBE S2125 has an optimised annual heating factor, which provides a low operating cost and hot water with high performance. The working area provides a single-flow temperature of up to 75°C. At an outdoor temperature of down to -25°C, up to 65°C is still delivered, while the sound level is low.
Together with the NIBE S-series indoor module with built-in wifi connection and the possibility of wireless accessories, it becomes a natural part of your connected home. The smart technology automatically adjusts the indoor climate and gives you complete control of the system from your smartphone or tablet. High comfort and low energy consumption - at the same time as you do nature a favour.
Natural Refrigerant
Operating range up to 75°C supply temperature and 65°C at –25 °C outdoor temperature.
Low operating costs
Optimized seasonal performance factor, low operating cost and high-performance hot water, using a natural refrigerant for a low environmental impact.
Low noise level
New design for low noise level.
Protector F1 is a market-leading inhibitor which prevents corrosion and limescale formation in central heating systems. This high-performance product offers superior protection by uniquely combining three inhibitors of organic particles, which bind to the metal within the heating system to protect from debris alongside anodic inhibitors which react with the system’s metal surface to create a protective layer, and cathodic inhibitors that combine with hard water salts to form an insoluble layer.
Cleaner F3 is an effective, universal pH neutral, non-foaming liquid cleaner, which removes sludge, scale and debris from existing central heating systems to restore heating efficiency and eliminate boiler noise. When commissioning new systems in accordance with BS 7593:2019 regulations and best practice, Cleaner F3 is ideal to remove flux residues and other installation debris to help extend the life of the boiler and the efficiency of the system.
It is suitable for use when powerflushing to accelerate the cleaning process in existing and contaminated systems. Cleaner F3 is a non-hazardous product which is compatible with all metals commonly used in heating systems, including aluminium.
