The Propex Heatsource HS2800 is the high-output sibling of the HS2000, offering superior heating power for larger vessels, narrowboats, and motorhomes. It maintains the same compact and efficient philosophy of the Heatsource range but is engineered to handle higher heating demands in more challenging environments.
Propex HS2800: High-Capacity LPG Heating
The HS2800 provides a robust heat output of 2.8kW, powered by Propane or Butane. With a significant air throughput of 85 C.F.M., it is designed to warm larger internal volumes quickly and maintain a comfortable ambient temperature through even distribution. Like all Propex units, it is fully room-sealed, ensuring that no combustion gases enter the living area—a critical safety standard for marine and RV use.
One of the key advantages of the HS2800 is its quiet operation. Despite its increased power, the unit is constructed with high-quality materials to minimize noise, making it suitable for overnight use without disruption. It features an intelligent electronic control system with automatic shut-off and precise temperature regulation via a digital thermostat.
Professional Installation and Technical Compliance
For a high-capacity LPG system like the HS2800, professional fitting is essential to ensure both performance and long-term safety. Our Gas Safe Registered engineers specialise in Propex HS2800 marine installations, ensuring full compliance with Boat Safety Scheme (BSS) regulations.
Upon completion of the installation, Marine Heating Solutions issues a Boat LPG Safety Certificate. For technical support, installation manuals, and diagnostic guides, users can access the official Propex Support Portal or review the Gas Safe Register’s marine safety advice.
