Heat pumps have gained a lot of attention in recent years, but with that attention comes plenty of myths and misconceptions. In this episode of Homeowners’ Q&A, we bring together a panel of experts to separate fact from fiction when it comes to air source heat pumps.
Our panel – Leah Robson from Your Energy Your Way, Derrick Denton from UK Alternative Energy and Mark Denman from Custom Renewables – tackles some of the most common myths surrounding heat pumps, addressing concerns that often leave homeowners uncertain.
One of the most frequently heard myths is that air source heat pumps are loud and noisy. Leah Robson explains that modern ASHPs are much quieter than people think. “When installed correctly, heat pumps operate quietly in the background and won’t keep you awake at night,” she says, debunking the misconception that heat pumps are disruptive.
Another common myth is that ASHPs are ugly and big. Derrick Denton addresses this, explaining that while older models were bulkier, modern ASHP units are designed to be more compact and discreet, blending into a home’s exterior without taking up too much space.
A particularly persistent myth is the idea that ASHPs aren’t suitable for period properties. Derrick shares insights on how proper sizing and installation make all the difference, noting that heat pumps can work just as effectively in older homes as they do in new builds, provided the insulation is right.
We also discuss the misconception that ASHPs are expensive to run. Mark Denman explains that, while heat pumps can have higher upfront installation costs, they are extremely efficient and can reduce energy bills over time, particularly when paired with renewable energy sources like solar panels.
Other myths we tackled include the belief that ASHPs can’t heat domestic hot water over 45°C, and the concern that ASHPs are constantly in defrost mode during winter. Both are false: ASHPs can reach temperatures well above 45°C with proper setup, and while defrost cycles do occur, they are brief and won’t leave your home cold.
Finally, we addressed the idea that all heat pumps are the same, regardless of brand. Mark explains that there are differences in quality, performance and reliability between manufacturers, so it’s crucial to do research and choose a trusted brand.
