I was sitting in my Hot Tub the other day relaxing and wondering how this whole Hydro massage, Hydrotherapy and Hot Tub thing must have started all those years ago.
I know that the original Hot Tubs as we know them were made of wood and were very popular in Japan two to three hundred years ago.
Then of course there were the Greeks, Phoenicians and last but not least the Romans, all of whom thought it was a cracking idea to have warm bathing coupled with massage. Moving quickly into more modern day times I have absolutely no doubt that back in time just over half a century ago (1954) when the Jacuzzi brothers Invented a portable whirlpool pump (simply as I understand it because one of their relatives had arthritis) that they would not have had an inkling that this would go on to form such a large and developing industry.
Hot Tubs and Jacuzzi style spas are now being made in most western countries to the highest standards and the development of the product continues at a pace. Apart from the original idea of being able to combine warm water and air to create the Spa effect there is no part of a Hot Tub that has not had improvements and amendments made to technology and indeed the construction and manufacturing processes used in making a Hot Tub have gone through considerable changes.
Whole industries have been spawned producing the components and raw materials that Hot Tub manufactures require. The Acrylic Sheets that form the Shell the electronic controls the pumps and motors. Each and every Hot tub manufacturer has tried to be at the cutting edge when introducing new ideas. Some of the many other items that spring to mind where inventors and design engineers together with entrepreneurs have made considerable changes would be:- Massage jets Controllers Heaters & Insulation Lighting Systems Ideas of re-using the heat generated by the pump and motors within the Spa its self. Equipment and accessory items - even the product's description would have undergone several permutations.
The original Jacuzzi pump, when coupled with jets using an air-injection system, a mixture not unlike a kind of bubbly water-and-air was created. With the natural efluxion of time, a variety of manufacturers experimented with methods to propel the air/water stream into the spa with ever increasing digress of pressure and control. Originally Spas used a simple idea that involved something like a vacuum cleaner motor but operating as a blower in some ways not unlike to blowing air into the hot tub in exactly the same way that we as children would have used a straw to blow bubbles in to a glass of pop. Again as time passed the designers soon began thinking of things like the venturi principle, in which water is pumped through a funnel-like device to create a vacuum that pulls in air. As the water flow and pressure increases, the jet automatically draws in more air, which results in more water flow and movement not unlike the idea of an exhaust driven turbo charger in a car.
Many modern Hot Tubs have the ability to bleed air into so that one is able to inject air into the Jets thereby increasing the pressure and movement of water to create a beneficial hydro massage effect.
The race goes on as every Hot Tub manufacturer continues to add more and more features to their products.
