Hot tub in pool

[Patriot]

How do submerged hot tubs work?

I don't think anyone here knows. I've seem them advertised, but that's about it.

Do you mean units like the "snorkel" and "scuba" heaters? There's a good chance they're included in the recent EPA ban on wood burning stoves (http://www.epa.gov/burnwise/ordinances.html#nsps).
