Air Source Heat Pumps (ASHPs) are increasingly becoming the go-to solution for efficient home heating and cooling. Also, they are the primary measure that we install under the ECO4 initiative. But misinformation surrounding this technology can make homeowners hesitant to make the switch. In this post, we’ll tackle the common myths about heat pumps and set the record straight based on expert insights.
Before we dive into the myths, let’s quickly define what an Air Source Heat Pump is. An Air Source Heat Pump (ASHP) is an energy efficient heating system that can replace your home’s boiler or other heat sources. It works by extracting heat from the outside air and bringing it inside to heat your home and provide hot water. The process involves capturing renewable heat from the air, using a compressor to increase the temperature, and then transferring this heat back into your home. As they only need a small amount of electricity to operate, they are a very energy efficient system making them an eco-friendly and cost-effective solution.

Myth 1: Air Source Heat Pumps Don’t Work in Cold Climates
Fact: Modern heat pumps are designed to work efficiently in temperatures as low as -15°C. Technological advancements, have made them viable in regions with harsh winters. According to experts, heat pumps work well even in areas that experience freezing temperatures.
Myth 2: Air Source Heat Pumps Are Expensive to Install
Fact: While the upfront installation cost of a heat pump can be higher than traditional heating systems, the long-term savings on energy bills make them cost-effective over time. Heat pumps are highly efficient, often providing 3-4 units of heat for every unit of electricity used.

Myth 3: Air Source Heat Pumps Don’t Save Enough Energy
Fact: Heat pumps can save up to 50% on energy bills compared to traditional heating systems. They are more efficient than gas or electric heating, providing significant reductions in energy use.
Myth 4: Air Source Heat Pumps Can’t Heat a Home Properly
Fact: Heat pumps can heat a home effectively even in cold weather. Cold-climate models are specifically designed for efficiency in colder regions, ensuring reliable warmth throughout the winter.
Myth 5: Air Source Heat Pumps Only Work for Heating
Fact: Heat pumps can both heat and cool your home. They are reversible, meaning you can use them for air conditioning during the warmer months as well.
Myth 6: Air Source Heat Pumps Are Noisy
Fact: Modern heat pumps are designed to operate quietly. The noise level compares to that of a traditional air conditioning unit or fridge, many newer models are specifically engineered to minimise sound.
Myth 7: Air Source Heat Pumps Are Only for New Homes
Fact: Heat pumps can be installed in both new builds and existing homes. With the right modifications, they can be retrofitted into older properties as well.
Myth 8: Air Source Heat Pumps Are Complicated to Maintain
Fact: Heat pumps are low-maintenance systems. They don’t require the frequent servicing that traditional gas boilers or furnaces do. Regular cleaning and annual servicing are usually enough to keep them running smoothly.
Myth 9: Air Source Heat Pumps Are Too Expensive to Run
Fact: Heat pumps are incredibly efficient. Their running costs are often lower than conventional gas or electric heating systems. In fact, they can provide up to four times more heat than the energy they consume.
Myth 10: Air Source Heat Pumps Don’t Work with Radiators
Fact: Heat pumps can work with existing radiators. However, it is recommended that they are paired with new modern radiators to maximise efficiency. As a result of this, under the ECO4 scheme we will install all new radiators along with your ASHP for FREE!
Myth 11: Air Source Heat Pumps Aren’t Reliable
Fact: Heat pumps are highly reliable and built to last, with many systems offering warranties of up to 10 years. With proper maintenance they can function effectively for 15 years or more.
Myth 12: Air Source Heat Pumps Can’t Work Without a Backup Heating System
Fact: In most cases, heat pumps can provide sufficient heat on their own, even in colder climates. In extreme cold weather, some systems may use a backup heater, but it’s not necessary for most homes.
Myth 13: Air Source Heat Pumps Are Bad for the Environment
Fact: Heat pumps are environmentally friendly. Unlike fossil-fuel-based heating systems, they produce fewer carbon emissions. By using renewable energy sources like the ambient heat in the air, they can help reduce your home’s carbon footprint.
Myth 14: Air Source Heat Pumps Don’t Last Long
Fact: Heat pumps are built to last and can typically function for 15 years or more. With the right care, they can have a long lifespan, making them a reliable investment.
Myth 15: Air Source Heat Pumps Are Only for Large Homes
Fact: Heat pumps come in a variety of sizes and are suitable for both large and small homes. They can be sized to meet the heating and cooling needs of any property, making them a versatile option.
Myth 16: Air Source Heat Pumps Are Only for Rural Areas
Fact: Heat pumps can be installed in both urban and rural locations. They don’t require a gas supply, which makes them particularly suited for rural areas, but they can also work well in city homes.
Myth 17: Air Source Heat Pumps Aren’t as Efficient as Gas Boilers
Fact: Heat pumps can be more efficient than gas boilers, especially when you factor in their lower running costs and lower carbon emissions. Heat pumps have a Coefficient of Performance (COP) of 3-4, meaning they produce 3-4 times more heat than the energy they consume.
Myth 18: Air Source Heat Pumps Are a Passing Trend
Fact: Heat pumps are not a trend; they are the future of energy-efficient heating and cooling. With governments incentivising their use (ECO4) and growing awareness of environmental issues, heat pumps are becoming a mainstay in the world of home energy systems.
Heat pumps are a game-changer for reducing energy consumption, lowering heating costs, and minimising environmental impact. Despite the myths and misconceptions surrounding them, they are a proven, reliable, and efficient option for heating and cooling your home. If you’re considering making the switch to a heat pump, don’t let misinformation hold you back.
