Thorne & Derrick and EXHEAT on The Bulldog
Terry McDonald commented:
“T&D are very excited about the EXHEAT MFH and foresee excellent opportunities to support our clients with their requirements for a long overdue portable heating solution for use in explosive atmospheres.
We believe the hazardous area heater is unrivalled in terms of capability, quality and performance.
Since introducing this ATEX fan heater to our clients, interest has been very high and first orders have now been received. T&D have over 25 years experience selling process heating equipment and this has to be one of the best innovations we have seen in that time.”
Katrina Parrott, General Manager at EXHEAT Industrial, explained the design approach:
“When developing The Bulldog we aimed to combine an efficient product design with simple functionality. The Bulldog is the world’s first truly portable heating solution for use in hazardous environments. It is a lightweight, tough and durable electric fan heater that can provide a stream of warm air up to 5 meters distance”.
She added:
“We listened closely to our customers and extensively researched the market in order to create a product that truly fills a gap in the hazardous area heating market. Initial client feedback has been extremely positive and, working alongside outstanding distributors such as Thorne & Derrick, we know The Bulldog will become an industry leading product.”

Portable heating for challenging environments – the original announcement promoted The Bulldog for onshore and offshore applications, including cold or confined spaces. Check the current product documentation to confirm suitability for your specific hazardous area.
Portable Heating for High-Voltage Electrical Work
Cold weather can make electrical installation and maintenance work more difficult. For cable jointers and utility workers, maintaining a comfortable working environment can help support dexterity and working conditions.
The EXHEAT MFH was promoted as a portable heating option for applications across the high-voltage and extra-high-voltage (HV-EHV) electrical power industry.
Potential application areas described in the original announcement include:
- Underground HV-EHV cable vaults.
- Cable jointing bays.
- Cable termination towers.
- Electrical substations.
- Switchgear environments.
When specifying heating equipment for these locations, assess the hazardous area classification and any gas, vapour or combustible dust risks. Confirm that the complete heater configuration is certified and suitable for the intended installation.

Heating for Cold and Confined Spaces
The Bulldog was promoted as a portable heating solution for cold working environments, including certain confined-space applications.
Before using any portable heater in a confined space or potentially explosive atmosphere, check the relevant risk assessment, ventilation requirements, hazardous area classification and product certification. Never assume that a heater is suitable for every confined space simply because it carries an ATEX marking.
The original HazardEx campaign also featured social media posts highlighting the product for cold-environment work.
