Debunking 5 Common Myths About Air Source Heat Pumps
Air Source Heat Pumps (ASHPs) have become a popular alternative to traditional heating systems, especially for those looking to reduce their carbon footprint and energy bills. But despite their growing popularity, plenty of myths and misunderstandings still circulate – often making homeowners hesitant to take the next step.
At Warmaway, we believe in clear, honest information. So let’s tackle five of the most common myths about ASHPs – and separate fact from fiction.
Myth 1: “Air source heat pumps don’t work in cold weather.”
Reality:
Modern air source heat pumps are designed to work efficiently even in sub-zero temperatures. In fact, the latest models can operate effectively in temperatures as low as -15°C – perfectly suitable for the UK climate.
While efficiency may dip slightly in very cold conditions, a correctly sized and installed ASHP will still keep your home warm and comfortable all year round.
Myth 2: “They’re more expensive to run than gas boilers.”
Reality:
ASHPs can be cheaper to run, especially when paired with good insulation and used correctly.
They operate by transferring heat rather than generating it through combustion, making them up to 300% more efficient than gas boilers. That means for every unit of electricity used, you could get up to three units of heat in return.
And with the rising cost of gas, the long-term savings on energy bills are becoming increasingly attractive – especially if you’re eligible for government incentives like the Boiler Upgrade Scheme.
Myth 3: “You need to replace all your radiators.”
Reality:
Not always. It’s true that ASHPs operate at lower flow temperatures, which means they work best with radiators that are properly sized for those conditions. But many homes already have compatible radiators – or may only need a few upgrades.

Myth 4: “They’re noisy and bulky.”
Reality:
Modern air source heat pumps are much quieter than people think – comparable to a modern fridge or dishwasher when in use. They’re designed to meet strict UK noise regulations, and when properly installed, you’ll hardly notice them.
As for size, most ASHP units are compact and can be discreetly installed outside your home, typically requiring less space than traditional oil tanks or biomass boilers.
Myth 5: “They require constant maintenance.”
Reality:
ASHPs are low-maintenance. A simple annual service – much like with a gas boiler – keeps them running efficiently and prolongs the life of the system.
We offer flexible maintenance packages for peace of mind, and our customers often find ASHPs more reliable over time due to fewer moving parts.
The Bottom Line
Air source heat pumps aren’t a futuristic fad – they’re a proven, practical solution for heating homes more sustainably and cost-effectively. But as with any technology, understanding how they work (and what to expect) is key to getting the most out of your investment.
