章節 1340: Famous Bathhouse (Part-5)

Alexander listened to Claude explain how the bathwater was heated with great fascination.

When he first saw the huge furnaces and heard of the huge quantities of water stored in the reservoirs, he had assumed the fire was used to directly heat up the bathwater stored underneath. 

That was the most logical conclusion. 

But his eyes soon felt open upon hearing how it was actually done- by using pumped hot air to heat up the bathhouse's floor which then transferred their heat to the water above.

And the reason why this was such a genius move was said by Claude himself, 

"If we directly heated the bathwater… then we would lose the heat as soon as we drained the dirty water. It would be impossible for us to reach even half of the temperatures we can reach now. Not to mention we would have long gone bankrupt from just the firewood bills."
