The Propex Heatsource HS2000 is a highly popular, compact LPG air heater designed for marine and RV use. It offers a balance of efficient performance and versatile power options, making it a reliable heating solution for smaller boats, narrowboats, and campervans.
Propex HS2000: Efficient LPG and Electric Heating
The HS2000 is engineered to provide a consistent heat output of 1.9kW using either Propane or Butane gas. One of its standout features is the optional Heatsource-E module, which allows the unit to run on 230V mains electricity with adjustable settings of 500W, 1kW, or 2kW. This dual-fuel capability is invaluable for vessels with shore power access or those wishing to utilise excess solar energy, providing a backup heating source should you run out of gas.
Designed for quiet operation and low maintenance, the HS2000 has a minimal electrical draw of just 1.4A during continuous running (12V/24V versions). The unit is fully room-sealed and comes as a comprehensive kit including a digital thermostat, stainless steel exhaust, and necessary wiring harnesses. Its air throughput of 60 C.F.M. ensures rapid warming and effective air circulation throughout the cabin.
