Eli5 How can one small flame in a boiler be enough to warm a whole houses central heating system?
In: Engineering
It’s not a small flame, it’s rows of burners that ignite from the pilot light when gas is supplied. The burners create heat that’s 100’s of degrees hot and the air then flows through the ducts and comes out the registers still very warm. That warm air mixes with the existing air to meet the desired temperature.
