So I’ve had a lot of experience helping people build float tanks… and I’ve come to the conclusion that radiant heating is the best way to heat your water, when possible. This isn’t some novel idea for people that know tanks, but for those who may be new to floating, here’s why:
1. Radiant can always be on to maintain the perfect temperature for LONG floats. (Over 1 hour) Whereas a non-radiant system will lose temp slightly over time, and will need to be turned on between floats to get back to temp.
2. No plumbing required! Less plumbing stuff… less chance for leaks.
3. It makes the water more consistent. Sometimes with heating systems that pump the water in, the water can have a cooler spot on the other end of the tank.
Simple, but great benefits. NOW, here’s the catch with radiant heating and what we had to do to get around it with our new tank. Radiant Heaters are known to have slight electrical noises when they turn on and off. We had to make a custom designed heat pad that was bigger and silent. This adds some cost, but it makes the floating experience right, and that is mandatory.
In developing these new custom heat pads we were able to add a lot more benefit than planned. The foam made the tank softer on the feet, and because it compresses it made it safer and less slippery to step into. The foam also insulates the water from the ground which helps maintain temperature. This is very important because we went with a thin wall design. Thin walls make the tank more affordable, and lighter to ship.
I’d love to hear your questions or comments on our radiant heating design. Please leave a comment below.
