NIBE heat pumps: models, specifications and conditions

Checked

Separate the NIBE S2125 outdoor unit from a complete system with an indoor module and cylinder. Model, phase, indoor unit and measurement source must match.

An independent overview of conditions and documented examples. We do not assign an overall brand score or confirm current stock.

S2125: exact models and combinations

The Slovak catalogue documents single- and three-phase S2125-8 variants with VVM S320 Nerez. A documented pairing does not establish current stock or assign every technical figure to that system.

Prices in the July catalogue were valid only until 30 September 2026, so we do not show them as current offers.

Winter output and seasonal efficiency

The seasonal declarations are Slovak S2125-8 values for W35/W55 and average climate; those rows do not identify an indoor pairing. Polish nominal part-load and maximum-output-without-defrost measurements are separate. We do not automatically assign them to a Slovak system. The S2125-20 conflict between Slovak and Polish declarations is excluded.

Missing standards, pairings or loads are not treated as zero. Figures with incomplete conditions are labelled technical examples. Request the complete data sheet for the exact combination before design.

Noise, refrigerant and installation

Quiet marketing does not replace model- and mode-specific sound power. Our Slovak seasonal example has no comparable acoustic row; request it for the actual phase, installation and output.

The exact manual must define placement, service clearances, any protective area, condensate and frost strategy. Nominal thermal output does not specify the electrical breaker or cable size.

Unit price or a complete system?

We do not have a documented current complete Slovak price for this exact system with comparable scope. A missing price is not treated as zero. Request equipment, indoor module, cylinder, accessories, labour, electricity, foundation, commissioning, VAT and all exclusions.

What the warranty evidence establishes

Dated conditions for sales from 10 October 2025 distinguish two years of full cover, ordinary parts through year five and the compressor through year ten, including its replacement, labour and travel. This is not ten years of full-system cover. Check paid extensions, registration and maintenance against the issued warranty; a general extension page may describe another programme.

Confirm in writing

  • Generation, full model codes, electrical variant and manual.
  • Output and COP at the same winter and water temperatures; SCOP with climate.
  • Which parts, compressor, labour and travel costs are covered.
  • Registration, paid inspections, exclusions and responsible service provider.
  • Installation scope, total including VAT and exact supported-equipment registration.

Common questions

Which S2125 figures can be directly compared?

Only the same quantity at the same temperatures, load, climate and measurement boundary. Another generation or indoor pairing does not automatically share the result.

What does the NIBE warranty include?

The written scope and its conditions determine cover. Compressor or materials cover is not automatically a complete system warranty including labour.

Is the unit price the whole budget?

Only if the scope says so. Connections, cylinder, electrical work, foundation and other work may be separate.
