HVAC Rentals were quick to help assist with emergency heater hire to London, when a multi-tenant office block required urgent temporary heating. The building comprised open-plan offices, meeting rooms, and a reception area spread across several floors. The facilities management company responsible for the HVAC system within the building acted fast and efficiently to action emergency heating hire as fast as possible after detecting an issue within their central heating system.Â
Rapid response keeps offices warm and compliant after rooftop boiler failure
During scheduled pre-winter maintenance, unfortunately the rooftop boiler plant tripped on safety lockout. As engineers traced the issue to a fault within a primary isolation valve and a leaking seal in the heating circuit, for safety, the boilers had to be isolated until replacement components could be lifted onto the roof.
This meant the entire building lost both space heating and domestic hot water — creating a compliance risk under the Workplace (Health, Safety and Welfare) Regulations, which require employers to provide suitable indoor temperatures and running hot water for hand-washing and hygiene. Hence the FM company contacted HVAC Rentals’ emergency heater hire team for immediate support. Â
Instant relief with Emergency heater hire using portable rental heaters
HVAC Rentals mobilised within hours, dispatching a fleet of portable emergency office heaters to stabilise conditions across occupied floors.
Within hours of the phone call the fleet of rental heaters were delivered via one of HVAC Rentals nominated drivers, enabling the FM team to implement emergency temporary heaters straight away, and before office staff were due to start arriving to their work day. The fleet of emergency temporary rental heaters included:
- Multiple 3 kW electric fan heaters for individual offices and meeting rooms
- Multiple 9 kW space heaters for the reception and open-plan areas
The plug-and-play portable rental heaters were distributed evenly, providing safe, fume-free heat indoors.
Temperatures increased from 16 °C to 21 °C within two hours of installation — immediately restoring staff comfort.
Same-Day Temporary Boiler Hire and Commissioning
Whilst the portable emergency rental fan heaters maintained warmth in the occupied areas, HVAC Rentals simultaneously arranged delivery of a 300 kW packaged boiler from its Henley depot. Logistics of ensuring the correct temporary boiler rental unit was undertaken as the priority pre dispatch/delivery. By coordinating with the client regarding requirements and logistics of installation, it was possible to organise same-day boiler hire, aiming for full restoration of hot water within the building as soon as possible. Â
The dual-fuel emergency boiler hire unit was offloaded into a neighbouring service bay — occupying a single parking space — and connected to the building’s heating circuit using 50 mm flexible flow and return hoses routed through an existing riser opening.
With integrated pumps, expansion vessel, and control panel, the rental boiler required minimal on-site assembly. Fuel and electrical connections were completed rapidly, allowing the system to be filled, purged, and fired for commissioning after hours the same day.

Outcome for the Client Requiring Emergency Heater Hire to London
By the end of the first day, the building’s heating and hot-water services had been fully restored through a combination of portable emergency office heaters and a temporary 300 kW packaged boiler.
The boiler hire was agreed for an initial four-week period, providing the FM company with stability while roof-level repairs and safety testing took place.
This approach allowed staff to remain on site throughout, avoiding productivity loss and ensuring continued compliance with workplace welfare requirements.
The arrangement also gave the client time to assess long-term repair options without the pressure of an immediate permanent replacement.
