Making a heater from an oil filter
The oil filter has a rolled edge that is ground off.
After this, the bottom is disconnected from the body. The filter is disassembled and cleaned. In particular, you need to burn the filter element to free the mesh from the paper. The design will use a body, a cover, a check valve and a mesh.
Holes are drilled along the upper edge of the filter housing to allow hot air to escape. We need to make more of them.
Holes are drilled in the filter cover for bolting 4 legs, which are used as furniture corners. Instead, bent drywall hangers can be used, but they are flimsy, so the structure will be less reliable during transportation.
You need to cut and bend a lid for the mesh from tin. It will allow for better heat dissipation in the future so that the top of the case heats up less, since open flames will not reach it.
You need to drill holes in the check valve for air flow. They are made along the edge.
The heater assembly looks like this:
A filter cover with legs is installed, and a check valve is placed on top of it. A lit candle is placed on it, then a mesh with a tin lid and a body.
If there is a lid on the mesh, the paraffin in the candle melts, causing it to go out faster. With this assembly, the heater can be used during winter fishing to warm your hands by placing them directly on the filter housing.
If you use a heater to warm up the tent, the lid is removed from the mesh. In this case, the candle in the sleeve burns as usual for 3-4 hours. However, during such an assembly, the body of the heater becomes hot, and it is better not to touch it.
A filter heater powered by candles, although it has a low thermal power, is enough to warm your hands in cold weather or maintain comfortable warmth in a tent when the temperature outside is positive. Such a device does not smoke, installs and ignites in a minute, weighs little and takes up almost no space.
