The drops trickling down the caravan windows when you wake up in the morning, stains appearing in the corners, a stuffy and heavy atmosphere… Whether you're in Northern Europe's cool campsites or the Mediterranean's damp winter coastlines, heating a small living space demands far more attention than heating a large house.
Space is tight, the air volume is small, and the wrong heater can quickly turn comfort into a problem. Caravan, tiny house, bungalow, or prefab home — the same question applies to all of them: is heating possible that doesn't take up floor space, is safe, and improves quality of life?
The Three Challenges of Heating Small Spaces
The first is floor space. In a caravan or tiny house, every appliance placed on the floor means space sacrificed from walking area or storage.
The second is condensation. In small volumes, daily activities like breathing, cooking, and showering rapidly increase the moisture in the air. When warm air hits cold windows and walls, the moisture condenses. Fogged-up windows, dampness, and mold over time are the most familiar problems of small living spaces.
The third is safety. Gas-canister or fuel-fired heaters work through combustion. Combustion consumes oxygen and produces combustion byproducts. In an enclosed, small volume, this requires serious attention.
Just 25 mm: On Your Wall, Not In Your Way
Sunlike Tec SL Series panels are only 25 mm thick. With their flat, smooth surfaces, they sit on a wall or ceiling like a picture frame. As stated in the catalog, they can be mounted flush against a wall or ceiling without fear of overheating.
The panels come with a low-profile, TV-style bracket attached to the back. Installation is completed in a few steps; we recommend that the electrical connection be made by a licensed electrician.
Two models stand out for small spaces:
| Model | Power | Heating area* | Dimensions (mm) | Weight |
|---|---|---|---|---|
| SL 160 | 160 W | 3 m² | 595×295×25 | 1.5 kg |
| SL 450 | 450 W | 8 m² | 595×595×25 | 2.6 kg |
*Heating area depends on insulation, usage pattern, and building structure.
At just 1.5 kg, the SL 160 is suitable for the sleeping area or small corners outside the bathroom. The SL 450, on the other hand, can be preferred for the main living area of the caravan or tiny house.
Doesn't Dry the Air, Doesn't Consume Oxygen
The SL Series operates using far-infrared radiation. Like the sun, it heats not the air but you and the surfaces around you. Because it does not move the air, it does not stir up dust and does not create a feeling of dry air.
Because it is electric and flameless, it consumes no oxygen and produces no combustion byproducts (CO/CO2). There's no gas-canister swapping, fuel hauling, or flue to worry about. It operates silently and odorlessly; it won't disturb your sleep at night.
The Power of Surface Heating in the Fight Against Condensation and Mold
Condensation occurs when moist air meets a cold surface. Because the SL Series directly heats the walls, ceiling, and furnishings, these surfaces stay warmer. Moisture has a harder time condensing on a warm surface.
This helps prevent window fogging and the formation of dampness and mold on walls. Of course, the habit of regular ventilation also remains important in every small living space.
For safe use, pay attention to a few rules from the manual:
- Do not cover the front surface of the panel; do not hang towels or clothing on it.
- Do not mount the panel at points where it could fall into water, such as a sink or shower.
- The SL Series is for indoor use; do not operate it outdoors.
In Tiny Houses, Bungalows, and Prefab Homes
The same advantages apply to fixed small structures as well. In tiny houses, a panel mounted on the ceiling frees up the entire floor. In bungalows and prefab homes, installation can be done without breaking walls or laying pipes.
Most of these structures have lightweight walls. The SL Series' low weight and slim profile offer a practical installation on these kinds of walls too. For manufacturers producing for different markets, the panel is a component that can be integrated into the structure from the very start.
Durability also matters. The SL Series comes with a heavy-duty stainless-steel resistance element, a bimetallic temperature switch, and an IP54 protection rating. It carries UKCA (United Kingdom) and CE (European Economic Area) conformity markings; it is manufactured in Turkey under UK license. It requires no maintenance and comes with a 3-year warranty and a 30-year service life.
Frequently Asked Questions
Q: Do Sunlike Tec panels work with a caravan's electrical system?
Caravans' electrical infrastructure varies by model and country. Before installing Sunlike Tec SL Series panels, we recommend confirming the suitability of your caravan's electrical infrastructure with our experts. It is recommended that the electrical connection be made by a licensed electrician.
Q: Which infrared panel model is suitable for a caravan?
For a caravan's small compartments, the Sunlike Tec SL 160 (160 W, 3 m²) stands out; for the main living area, the SL 450 (450 W, 8 m²). Heating-area values depend on insulation, usage pattern, and structure. The right choice is made according to the size and insulation of the area.
Q: Does an infrared panel prevent condensation in a caravan?
Because the Sunlike Tec SL Series directly heats the walls and surfaces, it helps prevent condensation, window fogging, and mold formation. Moisture has a harder time condensing on a warm surface. It is recommended to use it together with regular ventilation.
Q: Is an infrared panel safe in a caravan?
The Sunlike Tec SL Series is electric and flameless; it consumes no oxygen and produces no combustion byproducts (CO/CO2). It has a bimetallic temperature switch and an IP54 protection rating. For safe use, the panel's front surface must not be covered, and the panel must not be mounted at points where it could fall into water.
Q: How is an infrared panel mounted in a caravan?
Sunlike Tec SL Series panels come with a low-profile, TV-style bracket attached to the back, screws, anchors, and a spirit level. The bracket is used as a template, holes are drilled, and the panel is attached to the bracket and locked in place. At 25 mm thick, the panel can be mounted flush against a wall or ceiling.
Q: What is the warranty and service life of SL Series panels?
Sunlike Tec SL Series panels come with a 3-year warranty and a 30-year service life. They require no maintenance and operate silently and odorlessly.
Q: What conformity markings does the SL Series carry, and can it be used in different countries?
The Sunlike Tec SL Series carries UKCA (United Kingdom) and CE (European Economic Area) conformity markings. For use in a different country, confirm compliance with local regulations and electrical infrastructure with our experts. We are open to project-based discussions with caravan or tiny house manufacturers.
