Our claims explained
- Cheaper bills / Cost-saving smart tariff / Cheaper to run
Average savings for a medium-use home running a Cosy Eco heat pump on our Cosy Octopus smart tariff (no gas supply) are around £369/year compared to a gas boiler on a standard tariff. Full calculations and assumptions can be found in our [heat pump savings blog]. - Cleaner air / Low-carbon living
Using a heat pump emits less harmful nitrous oxide than a gas boiler, reducing pollutants linked to respiratory illnesses. See the Sustainable Markets Initiative Cleantech Homes report for more details. - Built to last
While gas boilers typically last 10–15 years, Cosy heat pumps are designed for 15–20 years of reliable operation. - Efficient
Heat pumps can deliver multiple units of heat per unit of electricity-typically 3.3 kWh heat per 1 kWh electricity (≈330% efficiency). In contrast, gas boilers in UK homes operate at about 85% efficiency, meaning heat pumps provide nearly 4× more heat for the same energy input. - Quiet / Efficient / Steady flow of warmth
Users report high satisfaction with heat pumps, noting that they are safe, reliable, quiet, and effective at heating homes and producing hot water (Nesta Heat Pump User Survey, May 2023). Our Cosy 6 heat pump has independently verified low sound power levels, ensuring quiet operation while maintaining a consistent, cosy indoor temperature.
