Important
A well-designed system will outperform a poorly designed one — regardless of brand. Scores assume correct heat loss, appropriate emitters, and proper commissioning.
How to choose the right heat pump
Start with your home, not the brand. Heat loss, emitters and commissioning decide comfort and bills more than the logo.
Non-negotiables
- Room-by-room heat loss
- Emitters sized for low flow temps
- Weather compensation set correctly
- Commissioning and homeowner handover
Common red flags
- “We’ll fit an 8/10kW and see”
- No discussion of flow temperature targets
- No plan for hot water strategy
- No noise/placement assessment
FAQs
Is the “best heat pump” the same for every home?
No — home heat loss, emitters, insulation and installation constraints change what’s best.
Should I choose the model first or the installer first?
Installer first. The installer’s design and commissioning has the biggest impact on comfort and running costs.
Why do some models have the same overall score?
They can be very close overall but win in different scenarios (retrofit friendliness, refinement, support, etc.).
