No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **

A ribbed radiator typically heats better than a flat panel radiator. The ribbed design increases the surface area of the radiator, allowing for more efficient heat transfer. This means that a ribbed radiator can heat a room more quickly and effectively than a flat panel radiator. Additionally, the ribbed design allows for better circulation of air, further enhancing its heating capabilities. **

In general, the size of a radiator does not necessarily determine its strength. The strength of a radiator is typically determined by factors such as the material it is made of, the design of the fins and tubes, and the quality of the pump. Therefore, a 420mm radiator may not necessarily be stronger than a 480mm radiator. It is important to consider the specific specifications and performance metrics of each radiator to determine which one is stronger for your particular cooling needs. **

To repair a radiator with a radiator sealant, first, ensure the engine is cool and the radiator is not under pressure. Then, locate the radiator cap and pour the sealant directly into the radiator. After adding the sealant, start the engine and let it run for about 15-20 minutes to allow the sealant to circulate and seal any leaks. Finally, check for any remaining leaks and top up the coolant if necessary. **

To remove the radiator from the radiator grille, you will first need to locate and remove any screws or bolts that are holding the radiator in place. Once these are removed, carefully disconnect any hoses or electrical connections attached to the radiator. Then, gently lift the radiator out of the grille, being careful not to damage any surrounding components. It's important to follow the specific instructions for your vehicle, as the process may vary depending on the make and model. If you're unsure, it's best to consult a professional mechanic or refer to the vehicle's manual for guidance. **

The radiator of the storage heater is still hot at 10 degrees because the thermostat is set to maintain a certain temperature, typically higher than 10 degrees. The thermostat controls when the heater turns on and off to keep the room at the desired temperature. If the room temperature drops below the set temperature, the heater will continue to generate heat to bring the room back to the desired level, which is why the radiator remains hot even when the external temperature is lower. **

To replace an old radiator with a towel radiator, you will first need to turn off the central heating system and drain the water from the existing radiator. Next, remove the old radiator from the wall by disconnecting the valves and brackets. Install the towel radiator in its place by fixing the brackets securely to the wall and connecting the valves. Finally, refill the central heating system and bleed the towel radiator to remove any air bubbles. **

Yes, a towel radiator can be installed instead of a regular radiator in a bathroom or kitchen. Towel radiators are designed to not only heat the room but also provide a convenient place to hang towels for drying. They come in various sizes and styles to fit different spaces and decor preferences. However, it is important to ensure that the towel radiator is compatible with the heating system in the home before installation. **
