Nibe Ground Source Heat Pump S1256 (1.5–8 kW, 3–13 kW, 4–18 kW) – Copper, Stainless, Enamel

Product Description

Experience Nibe’s most energy-efficient ground source heat pump ever—the Nibe S1256. This intelligent, inverter-controlled ground source heat pump features an integrated hot water heater and operates with a new, more climate-friendly refrigerant. Designed for homes up to approximately 400 m², the Nibe S1256 boasts an energy class rating of A+++ and an outstanding Seasonal Coefficient of Performance (SCOP) of up to 6.22, delivering exceptionally low operating costs and high hot water performance.

The heat pump automatically adapts to your current heating demands and operates quietly within a sleek, Scandinavian design. It is the ideal choice for both new builds and replacing existing heating sources.

Choose the Right Capacity and Corrosion Protection To accommodate all types of properties, the Nibe S1256 is available in three adjustable output sizes:

• S1256-8: Output range 1.5–8 kW
• S1256-13: Output range 3–13 kW
• S1256-18: Output range 4–18 kW (SCOP 6.22)

The integrated water heater is insulated with environmentally friendly cellular plastic for minimal heat loss. Select the corrosion protection coating that best matches the water quality in your area:

• Copper (Cu): The standard choice for most municipal water supplies.
• Stainless Steel (R): Ideal for water with higher calcium/lime content or lower pH levels.
• Enamel (E): Recommended for hard water or well water containing higher chloride levels.

Smart Features for Lower Energy Bills and High Comfort The Nibe S-Series brings smart home technology to the next level. Featuring built-in Wi-Fi connectivity, a full-color touchscreen, and the myUplink app, you get complete control from your smartphone or via voice control with Google Home.

• Smart Price Adaption (SPA): Tracks spot market electricity prices (e.g. Nordpool) and shifts operation to the cheapest hours of the day to reduce energy costs.
• Weather Forecast Control: Pre-fetches weather forecast data to adjust heat production prior to sudden temperature changes, ensuring a more consistent indoor climate.
• Wireless Accessories: Connect wireless sensors to monitor indoor temperature, humidity, and CO2 levels automatically.

Cooling Capabilities and Expanded Functionality The Nibe S1256 can be complemented with Nibe's range of accessories to create a complete climate control system:

• Passive Cooling (Free Cooling): Extract near-free cooling energy from the ground during hot summer days via a fan coil unit.
• Active Cooling: Switch to active cooling mode when precise temperature settings are required (e.g. bedrooms or wine cellars).
• System Integration: Easily combines with ventilation systems, solar PV production, and external heat sources.

Product Benefits:

• Top Energy Rating A+++: Outstanding SCOP of up to 6.22 provides maximum heat output per kilowatt-hour consumed.
