Rated heat output refers to the maximum amount of heat that a heating system or appliance is designed to produce under normal operating conditions. This is the level of heat output that the system is expected to consistently deliver. On the other hand, heat output range refers to the range of heat output that a heating system or appliance is capable of producing, which may vary based on factors such as the temperature setting and the specific conditions of use. The heat output range provides a more flexible and adjustable level of heat output compared to the fixed rated heat output. **
