How to Choose the Right Brand
- Max efficiency: Nibe, Viessmann, or Kensa (ground source)
- Best budget: Grant, LG, or Samsung
- Installer availability: Worcester Bosch, Vaillant, or Mitsubishi
- Quietest: Stiebel Eltron (32dB), Samsung/LG (35dB)
- Smart controls: Nibe (myUplink) or Viessmann (ViCare)
- Future-proof refrigerant: Any R290 brand (Nibe, Viessmann, Bosch, Stiebel Eltron, Worcester Bosch, Panasonic L-Gen, LG)
Remember: the installer matters more than the brand. A good installer with a mid-range brand will outperform a poor installer with a premium brand. If you are also considering solar panels, brands like Viessmann and Nibe offer the best integration.
Refrigerant Comparison
R290 models are the safest long-term choice. R32 remains legal and performs well but may face restrictions as F-Gas regulations tighten.
