Top 6 myths about heat pumps (and why they’re wrong)

The challenge of changing over to greener heating isn’t something we can ignore anymore. By the end of 2024, there were around 275,000 certified heat pump installations in the UK (up from around 190,000 in 2023.) We’re seeing progress, but that still only covers only a small slice of UK homes. To hit net zero by 2050, we’ll need to switch out gas boilers in millions of homes for something cleaner. 

Rising energy prices and talk of the government’s Future Homes Standard have encouraged homeowners to look into low carbon alternatives for heating and power. However, a lot of misinformation still surrounds heat pumps and other renewable energy devices, making the thought of switching over quite daunting.

We’ve debunked the most common myths we hear amongst our customers, so you can be fully clued up before you make the switch. 

Let’s separate the fact from the fiction.

Myth 1: “Heat pumps are too expensive.”

Yes, the upfront cost of a heat pump will cost more than your average boiler. But, the government’s Boiler Upgrade Scheme now offers £7,500 towards installation, giving you a strong kickstart. 

While electricity is often pricier than gas, heat pumps are three to four times more efficient than your average gas boiler, meaning they’ll use much less energy to heat your home. This will save you money in the long term, depending on your home’s insulation and setup. 

Don’t forget the value that a heat pump will add to your property in the long run too!

Myth 2: “Air source heat pumps are noisy.”

Think again… modern units tend to run from around 40-60 decibels – about the same as a fridge or a quiet office. UK planning rules also take this into account too, ensuring that noise does not exceed a certain volume in between you and your neighbour’s boundary.

Don’t stress about this one. Our team will always make sure your heat pump meets regulations and runs so quietly that you’ll barely notice it’s there.

Myth 3: “Heat pumps are not powerful enough to heat my home in winter.”

They can – and they do, even when it’s really chilly. Heat pumps are proven to work in temperatures as low as -16°C. If you don’t believe us, look at Norway, where over 60% of homeowners keep warm with heat pumps in weather conditions that are far more extreme than ours. 

Ground source heat pumps are particularly capable of maintaining their performance year round, regardless of weather conditions. If you’re concerned about reliability, speak to one of our team for advice about positioning your heat pump for optimum performance. We’ll use our expertise to ensure you’re getting the best out of your investment. 

Myth 4: “You can’t install a heat pump in old houses.”

Wrong. The age of your home doesn’t matter – what’s important is how much heat it loses. A professionally installed heat pump will be sized and designed to tackle a building’s heat loss, whether you’re in a new build or a period property.

That being said, insulation is always helpful. Much like a traditional boiler, adding double glazing, cavity or loft insulation can reduce energy demand, stop heat escaping, and lower your running costs while keeping your home warm. 

If you have an older or draughtier property, it’s worth reviewing your insulation first, but it certainly doesn’t rule out getting a heat pump. And just so you know, we’re always happy to advise on the most cost-effective setup for your home.

Myth 5: “Heat pumps are only useful in the winter.”

Did you know that heat pumps don’t generate heat, they move it? In winter, they pull warmth from the outside air or ground and circulate it around your home.

In summer, many modern heat pumps are built to reverse this process. Similar to an air conditioner, they can draw heat from your home and release it outside. And the best part? All of this happens without burning fossil fuels at all.

Myth 6: “You have to replace your whole heating system.”

Absolutely not. You won’t need to rip everything out. In many homes, your existing pipework and layout can stay the same. You might need to upgrade a few radiators, but most of the system stays put.

A professional installer will work with what you’ve got and adapt a heat pump to the system you already have in place.
