Here’s the thing about keeping your caravan warm—it needs to be quick, it needs to be efficient, and it absolutely can’t feel like you’re hauling around a brick. That’s where these electric caravan heaters come in. They’re built around a compact halogen infrared lamp that throws out serious, focused heat. Think of it as a tiny powerhouse. We’re talking a 400V, 2500W lamp, about 300mm long, wired through a standard R7s base. It’s designed to be small, but absolutely not weak. Power, Voltage, and Size The 2500W rating at 400V is all about packing a punch in a small space. The 300mm length is the sweet spot—it keeps the heater compact enough to squeeze into tight spots without cutting back on the heat. Going with 400V instead of 230V means the current is lower for the same wattage. That keeps the wiring thinner and cuts down on energy loss. But, and this is key, that kind of heat density means your caravan’s wiring and thermal setup need to be up to the task. The Inside Story: Halogen, Quartz, and R7s Inside, the halogen cycle keeps the light output steady and extends the life of the filament. The whole thing is housed in a quartz tube, which can handle the extreme heat and won’t crack when things heat up or cool down fast. The R7s connector is just a simple, two-pin design. It snaps in place and gives you a solid connection, which means fewer headaches down the road. When it’s time for a replacement, it’s a straight swap—no fuss. Why It Works for Caravans When you’re on the road, you want heat, and you want it now. You don’t want to wait for the whole space to warm up, and you certainly don’t want a heavy system taking up room. Halogen infrared does something smart: it heats objects and people directly, instead of wasting energy warming the air. It feels almost instant. And the R7s base? It makes installation a breeze. You can wire it up, swap it out, and get back to being warm without having to rework the whole fixture. It’s just straightforward, reliable comfort.
