What is the maximum square footage of heating surface permitted in a miniature boiler?

1. 10 sq ft

2. 15 sq ft

3. 20 sq ft

4. 25 sq ft

The correct answer is: 20 sq ft

The maximum square footage of heating surface permitted in a miniature boiler is 20 square feet. This limitation is established to ensure safety and efficiency in the operation of such boilers. Miniature boilers are designed to generate a specific amount of steam or hot water for heating applications, and limiting the heating surface helps to control the pressure and temperature within safe operating limits. Adhering to this maximum square footage aids in preventing potential hazards associated with overheating or over pressurization, which can lead to system failures or safety incidents. The regulations surrounding miniature boilers are tailored to maintain these safety standards while still allowing for effective heating performance.
