Description
NIBE S1256 is an intelligent and powerful inverter controlled ground source heat pump in two sizes. It provides optimum savings as the heat pump performs efficiently and automatically adapts to the property’s output requirements all year round.
It has a high seasonal coefficient of performance and an operating range of 1.5-13kW. With just over 0.5 tonnes CO2 equivalent refrigerant volume. The modulating compressor provides efficient output regulation and high reliability, making the heat pump suitable for most properties even with larger heating requirements.
A 173 litre Dhw tank is integral to the heat pump and is capable of producing up to 275l of hot water @40 degrees as per EN 16147. This positions the heat pump perfectly for installing in properties with up to 4 bedrooms.
Thanks to smart technology and an intuitive touch screen controller, the heat pump gives the user full control over energy consumption and the Intelligent controller automatically adjusts the indoor climate for maximum comfort & efficiency.
The S1256-8 PC variant of this product comes with all passive cooling accessories pre-built into the heat pump unit.
Features and benefits:
- Output sizes: 8 and 13 kW.
- Compact footprint with Integrated 173l hot water cylinder
- Highly efficient inverter controlled ground source heat pump in two sizes.
- Efficient output regulation and high reliability for lower running costs.
- Smart technology with user-friendly control for easy remote control.
- myUplink Smart app control capability
- Integrated underfloor drying function.
- Clear and easy to use touch screen controller.
- A wide range of system solutions and accessories.
- 1950 mm required ceiling height.
- Constructed on a robust frame with durable panels and high quality soundproofing for the best possible comfort. All panels are easy to remove to facilitate installation and for any servicing.
