Introduction: What is an air source heat pump?
People and businesses are becoming increasingly conscious of the environment and the impact their actions and behaviours have on the planet. Many of us are looking for ways to embrace a more eco-friendly way of living. Installing an air source heat pump offers an opportunity to reduce emissions, but what is an air source heat pump and what are the benefits for house builders and homeowners?
An air source heat pump is also known as an air-to-water source heat pump. Rather than producing energy by burning fossil fuels, an air source heat pump uses air. The pump transfers heat from the air outside to provide warmth in internal spaces via heating systems and radiators.
Using air source heat pumps is popular in many countries, but in the UK, we are still heavily reliant on gas heating. Over 84% of UK homes utilise gas central heating systems. Heat pumps account for just 1% of domestic heating systems (source).
How do air source heat pumps work?
Air source heat pumps transfer heat from the air outside a property to water. The system absorbs air to create a liquid, which travels through the heat exchanger to the heat pump. The heat pump increases the temperature of the fluid, turning the heat from the air into water. Through your central heating system, you can access hot water and power radiators and underfloor heating.
What are the eco benefits of air source heat pumps?
Environmental impact is a key consideration for housebuilders, developers, housing companies and buyers looking to purchase a new home. Green benefits are the most important reason to consider an air source heat pump for most people. Here are some key credentials:
- Reducing carbon footprint
Air source heat pumps are more eco-friendly than gas boilers. Statistics suggest that they can reduce carbon emissions by almost 25 tons within a decade (source). To illustrate the magnitude of potential savings, this equates to 30 return plane journeys between London and Madrid.
- Heating and cooling
Homeowners who want to enjoy warm winters and cool summers may assume that they need to install heating and cooling systems. To avoid this, you may wish to consider an air source heat pump, which can warm up and cool down your home using one system. By switching to a heat pump, you can regulate the temperature all year round while reducing your carbon footprint significantly.
- Boosting efficiency
One of the most advantageous aspects of an air source heat pump is boosting energy efficiency. The more efficient your system, the less energy you need to use. An air source heat pump makes it easier to heat or cool your home and lowers energy consumption.
In addition to the environmental benefits of reducing energy consumption, homeowners can also save money on their energy bills. Research shows that annual bills are up to £900 lower when comparing an air source heat pump with a G-rated gas boiler for a 4-bedroom house (source).
Air source heat pumps have become increasingly popular in recent years. One of the main reasons is their eco credentials. Heat pumps offer an alternative to burning fossil fuels. They reduce carbon emissions, lower energy consumption and provide versatile, efficient systems to keep houses warm or cool.
