Is an air source heat pump a noisy addition to the home?
In the past, heat pumps were known for their large size and considerable noise. However, modern advancements have made heat pumps more compact and quieter. They are now comparable in noise level to a standard refrigerator, according to the Energy Saving Trust. The hum you hear is from the fan, which is drawing air into the system. Improper installation might result in more noise, which is why a certified engineer should handle the installation. If your residence is a flat with an outdoor unit, you might notice the noise more.
Can UK homes accommodate air source heat pumps?
Contrary to common misconceptions, heat pumps can be integrated into nearly all property types, from detached houses and high-rise flats to contemporary homes and old farmhouses. There are, however, a few factors to consider. Ideally, you should have some garden space or an external wall where the heat pump can be mounted. Additionally, to maximize the benefits of a heat pump, it's important that your home is well-insulated or has the correct size heat pump to compensate for any heat loss.
Do air source heat pumps work efficiently in cold winters?
Even though heat pumps may be slightly less efficient in cold conditions, they still offer impressive performance. Air source heat pumps typically have an efficiency rate of 350-450%, which means they generate four times the energy they consume. While this efficiency might decrease by around 20% during winter, they still remain three times more efficient than gas boilers.
Are there government grants for heat pumps?
Yes, the Boiler Upgrade Scheme (formerly the Clean Heat Grant), which runs from April 2022 until April 2025, offers homeowners in England and Wales up to £7,500 for a new air source heat pump.
