Probably be almost cost-prohibitive, and very inefficient.The owner of the orginal Skagit Drive-in Theatre, who was a MIT graduate, came up with the idea of using underground pipes to pipe warm air into the cars during winter operations. Although the idea was good, it didn't work very well. By time the hot air got to the extreme ends of the field, the air was cold. Water heated floor? Well, if the idea didn't work very well with air in the drive-in attempt, I would presume the same basic idea would not work very well with a water heated floor, either. Our new theatre has a problem similar in the restroom. The hot water tank is so far from the bathroom, the hot water is luke-warm before it gets there.

Radiant Heat. It does work well in certain applications. The Hot Air idea that Paul Mentioned... I could see how that wouldn't have worked, but a circulating loop of hot water integrally poured in the concrete slab does work well (in some situations). Some of the more expensive homes in the affluent neighborhoods in Nashville ($600k & up) have a radiating loop installed under the tile floors in the bathrooms. Ir really keeps you from freezing your toes off during those mid-winter trips to the bathroom in the middle of the night. The house I grew up in had radiant heat in the ceilings. It was a series of electrial wires above the ceiling, and was susposed to radiate the heat down into the rooms. As we all know, HEAT RISES!! The result was a warm ceiling and a frigid floor. If I were intalling a new air handling system in a theatre setting, I personally would opt for gas heat in the winter and electric A/C in the warmer months. Nothing heats like gas, and it's more economical than electricity when used for heating.Paul, Your hot water problem can be easily solved by putting a recirculating pump on your hot water system. All of the medical facilities our firm designs have a "hot water recirculating loop". In essence, the hot water line from the water heater makes it's way from the tank to all of the fixtures in the building. At the further-most fixture from the tank, the line is then extended all the way back to the "cold water" supply side of the water heater. The "return line" is tee'd into the cold water supply feeding the tank, and a one-way check valve is installed on the cold water supply to the tank (that way no hot water can travel back into the cold water supply to the rest of the building). On the main hot water line coming out of the hot water heater, install an "in-line pump", which can either be controled by a timer or a switch. Once the pump is turned on, it will circulate the hot water throughout the building, delivering instantaneous hot water to each fixture. ------------------ Barry Floyd Floyd Entertainment Group Lebanon, Tennessee Stardust Drive-In Theatre Watertown, Tennessee

There's lots of coal left in the world, and in the USA. ![](http://www.film-tech.com/ubb/smile.gif) IMHO, oil, gas, and nuke have their disadvantages too. ![](http://www.film-tech.com/ubb/wink.gif) Solar Power? : The sun doesn't shine much in Rochester. ![](http://www.film-tech.com/ubb/wink.gif) http://www.kodak.com/US/en/corp/environment/index.shtml http://www.kodak.com/US/en/corp/environment/01CorpEnviroRpt/goals.jhtml ------------------ John P.
