The water in a Fonteyn Sunbelt portable Spa stays warmer longer with lower
energy costs thanks to the ingenious Heat Save System™ insulation system built
into the enclosure.

Rather than simply filling the interior of the enclosure with foam insulation, as many
spas do, the Heat Save System™ insulation system uses foam insulation on the
bottom of the shell, the floor of the enclosure, and all four interior walls, creating a
“dead air” space completely surrounded by insulation. This is the same principle as
the double-glazed glass in your patio door, and it works for the very same reason in
the portable Spa: dead air, surrounded by an insulator, traps heat more efficiently
than solid insulation itself.

Advantages of Heat Save System™ insulation system in a Fonteyn Sunbelt
portable Spa:

Portable Spa water stays warmer, longer, with lower energy costs

		Incidental heat generated by the portable spa pumps is effectively recycled
		back into the Spa (this not only lowers your spa’s heating costs, but also protects the pumps from overheating by providing a useful method of dissipating the heat they generate)

Interior pipes and plumbing are fully insulated against freezing

		Access to internal plumbing and the spa’s heater/pump systems is easy; the
		side insulation is actually attached to each removable side panel; when the panels are removed for service, the insulation is removed with the panel, allowing for unobstructed access.

The Heat Save System really is an added bonus with these quality portable Spas.
