The Thetford Triplex is an all-in-one LPG cooking solution that combines a three-burner hob, a 36-litre oven, and a dedicated grill into a single compact unit. This versatile appliance is a favourite for narrowboats and caravans, offering the functionality of a full domestic kitchen while effectively managing limited cabin space.
Thetford Triplex: Complete Culinary Versatility
The Triplex is engineered for high performance and safety, featuring a “shut-off lid” that not only protects the burners but also serves as extra workspace when the hob is not in use.
- Multi-Burner Hob: Includes one high-output 2.4 kW burner and two 1.8 kW burners, allowing for diverse cooking tasks simultaneously.
- Integrated Oven & Grill: Features a reliable 1.6 kW oven and a 1.6 kW grill, perfect for everything from roasting to quick toasting.
- Safety Shut-Off Lid: The glass lid automatically cuts the gas supply to the burners when closed, preventing accidental ignition.
- Reliable Ignition: Equipped with a 12V electronic ignition system for easy lighting via the vessel’s battery.
Professional Gas Safe Installation
Due to its high total heat input (9.2 kW), the Thetford Triplex requires expert installation to ensure sufficient gas flow and proper ventilation. At Marine Heating Solutions, our Gas Safe Registered engineers specialise in Thetford Triplex installations. We ensure that the 5/16″ spigot connection is secure and that the installation fully complies with Boat Safety Scheme (BSS) regulations.
Following every installation, we issue a Boat LPG Safety Certificate, essential for insurance and residential mooring requirements. For official technical support, visit the Thetford Europe website or consult the Gas Safe Register.
