Inspired Technology
Granville knows the importance of choosing a spa that is made of the highest quality components, designed and manufactured to stand the test of time. We believe in delivering the quality and finish you expect in a superior lifestyle product.
Our exclusive Thermo-Lock© Barrier Insulation system makes your Granville Spa a world leading product in energy conservation. We minimize heat loss and maximize the energy used to maintain the spa temperature even in the coldest climates.
Our advanced design utilizes the existing ambient heat already being generated by the spa massage motors to reduce costs. This process allows the air warmed by the pumps, to circulate within the sealed cavity of our spa support frame. This existing heat is used in the compartment under the seating area of the spa and helps maintain and stabilize the overall water temperature. The net affect is a reduction in operating costs. This process is similar to how hybrid cars utilize gas motors to recharge the battery for economical operation. We seal in the cavity of the spa frame with the most advanced space age barrier insulation technology to lock in heat. Granville Spas operate on pennies a day
Full Flow Plumbing
Inspired design at Granville Spas in our new series of spas and other selected models is our breakthrough FFC Full Flow Plumbing. Granville’s new series of spas (2-3 pumps) use our breakthrough technical hydrostatic design FFC© to provide every therapy seat with the full power of all pumps and a greater variety of therapy intensities.
This breakthrough in plumbing design allows more choices in massage therapy pressure on all seats and jet configurations. Pumps are able to utilize their full massage velocity to deliver the correct pressurized water flow to all the therapy seats. Our unique hydrostatic design eliminates plumbing line resistance, this flaw in most designs saps flow pressure from jets in many manufacturers’ spas. In Granville Spas design, conventional hydro-jet pressure at every seat is maximized. This added flow velocity allows us to offer four distinct massage intensities where our competitors offer only two.
Versatile Seat Therapy controls
Our unique control designs allow bathers total operational control, specialized therapy seats in many models offer conveniently placed underwater tactile controls to activate specialized jets for neck and shoulders. No more getting out of the seat or reaching across others to adjust neck jet controls.
Pattern Jet clustering
Our unique jet configurations offer therapeutic combinations for specific massage types from firm to gentle. Our specialized clustering equalizes water pressure to give each seat perfect massage jetting.
Energy Efficient Pumps
The optimum spa design is one which delivers the optimum massage therapy, using the most energy efficient pump to deliver it. Excessively large pump HP ratings look impressive on paper but do not really perform better. Spa therapy is based on efficient and effective plumbing combined with proper jetting and using correct water flow. Oversized pumps are used to compensate for poor plumbing design and use excessive electrical energy.
At Granville, our spas are equipped with single, dual or triple pumps only where the jetting patterns demand it, therapy is our business. Our certified horsepower ratings provide maximum massage therapy at every seat using the most efficient pumps possible.
Filtration
Most Granville spa series are equipped with dedicated filtration pumps that quietly and efficiently provides constant circufiltration and ozone production, keeping your water crystal clear.
