TemperLok™, Heat Isn’t All You’re Saving.

PDC Spas® has engineered a unique system that maximizes energy efficiency and minimizes heat loss rivaling our foam-filled competitors. Unlike foam-filled units which hide manufacturing defects and make servicing expensive, the sophisticated engineering of our TemperLok™ system keeps the spa lightweight, economical to own and operate. The PDC Spas® design assures your insulation is intact from the day you purchase through the decades of enjoyment. TemperLok™ ingenuity was developed considering low monthly costs, service and installation for your long-term satisfaction.

Waste heat from pump operation warms the air cavity behind the cabinet and is radiated and absorbed back into the spa plumbing. Warmed air is trapped between our TemperBase™ insulated floor panel and cabinet top gasket creating efficient thermos air-tight insulation.

Efficient Design for Economical Servicing

From the bottom up, PDC Spas® assures your unit is protected from cold temperatures and unwanted outside elements. A three-layered floor construction includes a tough ABS plastic which seamlessly covers the entire bottom, wrapping upward onto the cabinet sidewalls. A thick layer of foam insulates for temperature control while the wooden layer provides strength and rigidity for a unit that is both energy-saving and durable. An inside reflective thermal barrier ensures outstanding thermal efficiency. PDC Spas® TemperLOK™ insulation system provides maximum energy savings while maintaining a lightweight unit for easier installations. The use of a strong fiberglass, non-filled resin backing with an insulating foam coating provides maximum strength and efficiency. Using this process, a PDC Spa is more costly to manufacture, however each and every PDC spa unit is made with quality and efficiency in mind.

Heat Trapping, Safety Thermal Covers

Energy Savings at PDC Spas® is completed with our locking, thermally efficient cover. This is an important feature of energy conservation as most heat escapes from the water surface; compare this to steam escaping from a styrofoam cup of hot coffee. Only the highest quality hot tub covers are offered standard at PDC Spas®. As seen here, our efficient covers trap heat even preventing snow melt on the cover surface. Consider the PDC Spas® AccuLok™ Hot Tub Cover with heat trapping design and water-resistant barrier for added performance. 7 Year Warranty. AccuLok Flyer

What Will Operation Cost?

That is a difficult question to answer honestly and one should be aware of the many variables that play into providing an estimate of energy use. In comparison, asking this question is similar to asking an auto salesman should you purchase a new car, how much fuel will I use. Your desired water temperature, outside temperature, how often you use the spa, the type of cover you have and how often it is covered plus the kilowatt charge in your location are all variables that are to be considered. 

With thousands of PDC Spa owners, who have enjoyed their spas for several decades, it is reported about $1-$1.50 per day in energy cost.
