<div dir="ltr">Dear Duncan,<div>One of gigs that I worked years ago was the 'Donny and Marie' show, where they heated a shop-built pool with a very long piece of spiraled Nichrome wire,right off the roll, hooked directly with 4/0 to a company switch fused at 400 amps.<div>/s/ Richard</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Dec 10, 2015 at 11:43 AM, Duncan Mahoney via Stagecraft <span dir="ltr"><<a href="mailto:stagecraft@theatrical.net" target="_blank">stagecraft@theatrical.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Having built more than a few pools onstage in my time, I'll pass on that bromine works just as well to disinfect the water as chlorine, without the chlorine smell. It costs a bit more, but most theatrical pools are not all that big and a little bromine goes a long way. And for small (a few hundred gallons) pools, a lot of submersible aquarium heaters can do the heating for a comparatively small investment compared to a full-on pool system. Remove the heaters from the water when actors/crew are in the pool, if the glass breaks on a heater, the water will be electrified until the GFCI trips<br>
<br>
Oh BTW, have a plan for focusing the lighting that does not involve an electrician standing on an aluminium stepladder placed in the pool full of water. (Yes I did work that gig...)<br>
