Experience some relaxation while applying some green awareness as well with these new portable hot tubs from Bullfrog Spas. These new tubs are constructed without the wood and other non-renewable natural materials still used by other spa manufacturers and Bullfrog does not use potentially harmful fiberglass. These new products promise to offer more health benefits and bringing down the use of power, a key factor on how tubs like these can retain heat.
90% of the spa plumbing is contained on the back of each JetPak, which is actually submerged inside the hot water of the hot tub. With the plumbing submersed, any heat escaping through pipes is transferred into the spa water instead of being lost to the environment, heating the spa and recycling energy.
