Origo 5100 Heat Pal heater/stove. No pump that can break and no risk of explosion because the fuel is not pressurised. The top cover mainly serves as a safety measure to protect you from getting in direct contact with the flame. To use it as a heater, light the alcohol fuel and leave the cover on, or remove the cover to use as a single-burner stove. As for the fuel container, it contains a non-flammable material that absorbs the alcohol and helps give an even burn. Fueled by denatured alcohol, it is safe, efficient and easy to use. Please note: The sloped portion of the fuel canister is used as a filling reservoir to avoid spills. This is not a defect. Output: 5,200 BTU (1500 Watt) High quality stainless steel and aluminum construction. Offers a foolproof backup cooking/heating option in case of power outages. Asking $150
