  • Common Myths Debunked

    "Heat pumps don't work in cold weather"

    Reality: Modern heat pumps work efficiently down to -20°C. Scandinavia has the highest adoption rates globally.

    "They're too noisy"

    Reality: Modern units are quieter than a fridge (40-60 dB). Planning permission rarely required.

    "You need underfloor heating"

    Reality: 80% of installations work with existing radiators. Some may need upgrading to larger sizes.

    "They're too expensive to run"

    Reality: With current electricity/gas prices, heat pumps are 20-40% cheaper to run than gas boilers.
