If the radiator is hot but still not warm indoors, it could be due to the following reasons:
1.Poor room insulation: If the room is poorly insulated, heat can be quickly dissipated, resulting in an indoor temperature that cannot be kept as warm as it needs to be. You can consider taking insulation measures, such as adding window seals and adding soundproofing materials, to improve the insulation performance of your room.
2.Poor heating layout: If the radiators in the room are unevenly distributed or not properly arranged, the heat may not adequately cover the entire room, resulting in low temperatures in some areas. This may require repositioning the radiators or adding additional heating equipment to improve the heating results.
3.High ceilings or large spaces: If the room has a high ceiling or a large space, the heat will rise and disperse to a higher location, causing the lower areas of the room to be less warm than warm. In this case, consider installing a fan or auxiliary heating device to improve air circulation and even heat dissipation.
4.Insufficient radiator power: If the radiator power in the room is insufficient to meet the heating needs of the room, the indoor temperature cannot reach the required level of warmth. You may want to consider replacing a higher power radiator or adding other supplemental heating equipment.
5.Other heating system problems: In addition to the above reasons, there may be other heating system problems, such as abnormal pump operation, pipe leakage, incomplete valve closing, etc. These problems may affect the normal operation of the heating system and the heating effect, it is recommended to consult a professional heating engineer for a comprehensive inspection and repair.
If you have tried the above solutions and still cannot solve the problem, it is recommended to consult a professional for evaluation and investigation to find out the specific cause and provide a solution. They can provide more accurate advice and assistance based on the situation on site and your needs.
