Air-source heat pumps could be about to retrofit Europe

October 23, 2023
In many homes across Europe, nestled amidst kitchen essentials or hidden away in utility rooms and cupboards, gas and oil boilers have been long-time sentinels of comfort.

At their naissance, they heralded a new era—ushering central heating and instantaneous hot baths into homes, obviating the laborious coal shovelling of the past.

As we inch toward a decarbonised future however, their time could soon be up as a dozen European nations are gearing up to say farewell to fossil fuels in domestic heating.

Stepping up to the plate as the frontrunner to replace them is the air-source heat pump which uses clever technology to draw latent heat from the ambient air—even in the heart of winter—and magnify it to dispense warmth indoors.

Their energy efficiency is impressive too, notably surpassing that of traditional boilers. However, they’re implementation has not come without challenges, emblematic of the teething problems that arise as nations ambitiously push for decarbonisation.

While green transitions in the past typically sidestepped causing major disturbances in citizens’ lives, this era seems different, and the transition, somewhat predictably, hasn’t been universally embraced.

For starters, it’s still not as simple as exchanging your old gas boiler for a sleek new heat pump—at least not just yet. The latter’s bulkier design demands outdoor real estate, and in Europe, where a significant portion of homes bear the weight of years and are not energy-efficient, the installation of such pumps necessitates bolstered insulation.

In places like Britain, discerning a reliable authority on sustainable heating alternatives can further deter all but the affluent and passionate green advocates.

Heritage homeowners grapple with decisions—whether to upheave their floorings for interior insulation or opt for a thicker external insulating coat, often stymied by local regulations. Such endeavours are not just arduous but can also strain wallets and political capital. Germany recently attempted to outlaw gas and oil boiler installations, however promptly shelved it following public dissent.

The solution also isn’t singular. Easier-to-install heat pumps are on the horizon, but even they cannot promise a disruption-free transition.

At the bare minimum, governments must facilitate a smoother switch. Financial incentives are present in certain regions, though often mired in bureaucratic lassitude—demanding acceleration.

Ambitious decarbonisation targets flounder without an adept workforce; training initiatives must surge. The tug-of-war between green mandates and local planning laws, which currently leaves homeowners in a lurch, mandates a resolution.

Germany’s forthcoming regulations, set for parliamentary deliberation, proffer a more patient timeline, inviting local bodies to the strategic table. These provisions allocate varying transition timelines to municipalities based on their size, allowing for a broader spectrum of eco-friendly heating alternatives.

With a more intimate understanding of local architectural legacies and a say in planning, municipalities are for once better positioned to navigate retrofitting roadblocks. But their allegiance must tilt decidedly toward planetary welfare.

Achieving requisite decarbonisation, pivotal to staving off ecological disasters, has proven not to be simple. Electoral tides may turn against eco-advocates, and so it is imperative to architect policies that adeptly trim emissions, favouring persuasion over compulsion.

Yet, even with visionary planning, resistance is inevitable.

Governments, brace yourselves.
