What to Look for When Choosing a Heat Pump
Efficiency
Look beyond headline efficiency figures. Real-world performance depends on system design, radiator sizing, and flow temperatures. If you’re comparing long-term bills, read our Heat Pump Running Costs guide.
Noise Levels
If the outdoor unit is close to neighbours or living spaces, low-noise models should be prioritised. This is one reason quieter systems like Samsung EHS Mono R290 can be attractive for urban homes.
Controls
Smart controls can improve comfort and efficiency. The right thermostat setup can make a noticeable difference, so it’s worth comparing the best smart thermostats for heat pumps.
Installer Quality
The installer matters just as much as the brand. A well-installed system will always outperform a poorly installed one, especially in homes where radiator sizing needs attention.
Best Smart Controls to Pair with a Heat Pump
The heat pump itself is only part of the system. Controls, thermostats, and accessories can significantly improve comfort and efficiency.
