According to Arctic Hayes, this is driving renewed demand for reliable portable heaters that allow installers to work safely, keep properties warm and avoid project delays - but the emphasis is increasingly on choosing the right type of temporary heat for the job, customer and environment.

Temporary heating has quietly become one of the simplest ways for heating professionals to protect themselves and their customers during busy periods. When a boiler fails and parts are days away, when pipework needs to be isolated, or when a retrofit means the system is off longer than expected, the right heater can make the difference between a manageable job and a distressed customer. It also reduces the risk of frozen pipes and creates safer working conditions in cold properties.

Different callouts now demand different solutions. Oil-filled radiators, with their enclosed heating element and steady output, are often preferred in settings where a heater may be left unattended or used by vulnerable occupants - such as landlord properties, managed housing or healthcare environments.

Fan and convector heaters, meanwhile, remain a go-to for installers who need fast warm-up in voids, workshops and during short maintenance windows. For many, having both options available ensures they can match the heat source to the situation rather than rely on a one-size-fits-all approach.

Arctic Hayes’ portable electric heaters are built around this everyday trade reality: quick to deploy, easy to move between jobs and equipped with the safety features installers rely on when working in occupied homes or draughty site conditions. 

Lee Parsons, managing director at Arctic Hayes, says installer feedback has been consistent: “Installers tell us the same thing every year - when the weather turns, they need something they can plug in and trust. Portable heaters won’t fix the underlying issue, but they keep people warm, keep properties safe and keep the job on track. Choosing the right unit for the right situation is what really makes the difference.”

Interest is also growing from heating businesses looking to reduce call-backs and improve customer experience. Providing appropriate temporary heat while a system is offline helps manage expectations and reduces the urgency that often leads to rushed decisions or unnecessary replacements.

Arctic Hayes expects more installers to build temporary heat into their standard workflow – not as an upsell, but as a practical tool that supports safer working, smoother scheduling and better outcomes for customers.
