If electric you'd need shore power to it properly, but if on shore power you'd have other easier and cheaper options.

There is a UK company that manufactures electrical underfloor heating pads which can be laid under laminate floors or fixed carpeting. But look at it: we do not even know who YOU are, we just see that SOMEONE looks at our pages, how he/she does that, how long this SOMEONE lingers on the respective pages, etc. Again, you need to be careful about ventilation, but they heat up the space quickly and stay warm for a while. Ideally, consult a HETAS-qualified installer before you think about installing a wood burner yourself. To ventilate the space, otherwise you’ll get condensation in your van but you also run the risk of carbon monoxide poisoning!In addition, the heating film underlay protects the existing floor covering from possible uneven fading and, depending on the design, can partially or even completely accommodate the connection cables / connection points of the heating film. Yes, it’s perfectly safe to leave certain types of motorhome heaters on overnight, if they are in good working condition, and you follow the manufacturer’s instructions.

Different versions are available for 12V (30cm / 50cm wide) or 24V (30cm / 50cm wide) mains voltage, as well as for the normal mains voltage 230V* (30cm / 50cm / 80cm wide). Table: As a rule, heating films can be laid over the entire surface under a table with an H-frame, as is often found in caravans. So if the walls, floors and objects in a room are warm, we feel comfortable even at lower air temperatures. Heaters with no safety features: Motorhome heaters with no safety features can be risky because they can cause fires, explosions, and carbon monoxide poisoning. If a thick heating film underlay were to be installed underneath, the whole structure would give way too much under load.Both systems are reliable, but not cheap to install, so make sure you plan to use your van a LOT before you invest in this type of motorhome heating. If you have any questions, please do not hesitate to contact us and we will work out the perfect solution for your project together with you. there was a system of painting an area ( wall/floor) with conductive paint and applying a low voltage with a high current transformer thereby heating the whole room, never realy caught on.
