Heat pump myths busted!

Heat pumps are making headlines for a reason—they play a crucial role in the Government’s Net Zero strategy by heating homes without relying on gas or oil. Navigating the myriad opinions on their effectiveness and investment value can be confusing.
Don’t worry; we’ve debunked common heat pump myths to simplify the decision-making process. Making the switch might be easier than you think!

False. Dispelling a common myth about heat pumps—it’s false. Even during chilly winter days, there’s ample heat in the air and ground for heat pumps to absorb. Remarkably, the refrigerant can capture warmth in temperatures as low as -15°C, and by compressing it to a higher temperature, your home stays comfortably warm. In the UK, air source heat pumps are usually sufficient, as extremely low temperatures are rare. However, for frigid climates, a ground source heat pump may excel, especially since the ground remains above 10°C even in harsh winters. Surprisingly, Sweden, known for its cold winters, leads Europe in heat pump adoption.

False. They are sometimes criticised for noise, but with proper installation and placement, they generate less sound than expected. Air source heat pumps produce 50-60 decibels, slightly louder than a low library whisper, while ground source heat pumps are even quieter without a fan. Modern models are increasingly quieter with improved features. If a heat pump becomes excessively loud, it often indicates a potential issue.

False. Typically, installing a heat pump doesn’t require planning permission, but checking is crucial. In rare cases where permission is needed, it’s often due to noise concerns for neighbours. Professional installation is key—they ensure optimal placement, minimising the likelihood of requiring planning permission by positioning it away from boundaries.

False. Despite using electricity, heat pumps are environmentally friendly. They’re highly efficient, producing 3.5kWh of heat for every 1kWh of electricity, surpassing traditional boilers. Moreover, they eliminate the need for polluting gas or oil. Enhance your heat pump’s green impact by opting for a 100% renewable energy tariff, ensuring your system runs on eco-friendly wind or solar power for the greenest operation.

False. After installation, heat pumps demand minimal maintenance, often less than traditional heating systems. With a lifespan of at least 20 years, replacement parts are typically unnecessary. A brief annual service ensures its continued efficient operation for many years.And for extra reassurance Boxergy offer Service Plans crafted to your individual needs.

False. While heat pumps come with a higher upfront cost compared to standard boilers, their extended lifespan and reduced repair expenses make them a more cost-effective choice in the long run. Government grants of £7,500 for homeowners further support the transition to sustainable alternatives. Opting for our services also includes an extra support, making the switch more affordable.

False. Air source heat pumps require significantly less outdoor space compared to ground source heat pumps. While a ground source heat pump typically needs a garden area twice the size of your property, an air source heat pump is more compact. If you have enough space for two washing machines side by side, it’s sufficient for an air source heat pump—no need for a vast garden. Generally, planning permission isn’t required for air source heat pumps, except in specific cases like conservation areas. However, it’s essential to be aware of regulations, such as maintaining a one-meter distance from boundaries in England and Scotland, and a three-meter distance in Wales.

False. While a well-insulated home is essential for optimal heat pump performance, these systems can function effectively in the majority of British homes, even those experiencing some heat loss in colder months.

False. While heat pumps are well-suited for underfloor heating systems, they also integrate seamlessly with radiators. Due to their optimal performance at slightly lower temperatures than traditional boilers, you might consider installing additional or slightly larger radiators to maximize the advantages. However, every home and heat pump combination is unique, and our expert engineers can guide you in determining the specific requirements. If your home is already well-insulated, you may find that no adjustments are necessary at all.

False. Heat pumps are just one aspect of the long-term solution. While heat pumps excel in well-insulated houses, not all UK homes are suitable for this technology.
