Frequently Asked Questions What is the difference between 12V and 24V? 12V suits most caravans, campervans, motorhomes and smaller battery systems. 24V is commonly used in trucks, buses, marine applications and larger battery bank setups. What size space is the H2S best suited to? The H2S 2kW heater is ideal for smaller caravans, campervans, boats, cabins and other well-insulated compact spaces. Does the kit include a fuel tank? Fuel tanks are often selected separately depending on your preferred size, mounting location and installation layout. How much battery power do these heaters use? These diesel heaters have a higher power draw during startup while the glow plug ignites the fuel (approximately 8–10A for a few minutes on 12V models), then settle to a low running draw of around 0.8–2.5A depending on heat setting. They are very efficient and well suited to caravans, RVs, cabins and off-grid battery systems. Can I install this myself? Confident DIY users may be able to install this heater, however professional installation is recommended for fuel, electrical and exhaust safety. Can I add extra vents or ducting? Yes. Additional vents, ducting and accessories can often be added depending on your layout and heating requirements. Do you offer accessories for these diesel heaters?
