    When was central heat and air invented?

    It wasn't until the 1830s when hot water heating systems developed rapidly, being adapted into churches and factories across England. The radiator an important piece of modern central heating was invented in the late 1850s by Russian inventor Franz San Galli and adopted by most of Europe and the United States.

    He a Google answer to a question no one asked...yeah.
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    I thought the Roman's were the first.

    What about the American Indian's? The had central heat, that fire in their TeePee.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    Did you really need the " If you were a real tech " ??

    I have it on good faith. A long time ago the Egypt's (rich ones) had "workers" drag huge rock blocks out into the desert in the evenings to get cooled by the deserts cold temps, overnite, then those workers would return with their version of Central Air Cooling. Those blocks were cold.

    George Washington’s Mount Vernon Home supposedly had central cooling. During the Winter they’d cut blocks of ice out of a Potomac River pond, put them in the Cellar, packed in Straw and Sawdust. They would uncover portions of the Ice and open vents, letting the night breezes push the cold air up through the house.
