Choosing the right spa
Spa World has been Australia’s leading supplier of spas for many years. With history comes experience and we believe that we know what goes into making a great spa.
We use this experience to ensure that every spa we sell, meets our own stringent standards. By working closely with our suppliers, we can guarantee that they design and produce the best possible product, from our economy range, right through to our flagship models.
Please take some time to learn about what goes into Australia’s best range of spas:
Spa shells are formed by heating a flat sheet of coloured acrylic in an oven and then drawing it into a spa mold. After forming, the acrylic sheet becomes very thin – in some places less than 1mm thick. As a result, the acrylic must be strengthened using fiberglass. Because acrylic has a very smooth surface, the first layer of fiberglass must use a special vinyl ester resin, which actually melts itself into the back of the acrylic. If this resin is not used, your spa can delaminate over time. All Spa World spas incorporate vinyl ester resin.
As an additional quality assurance measure, all Spa World spa shells are cured in a temperature and humidity controlled curing oven. If the step is missed, the spa shell may delaminate, even if vinyl ester resin has been used. Most spa companies do not have this technology in their manufacturing process.
There are many ways to insulate a spa. Insulation is very important as it determines how much a spa will cost to operate. The simplest and most common method is to spray a layer of foam onto the spa shell. This system is cheap and easy for the manufacturer; however, it rarely provides what we believe to be adequate levels of insulation. We insist that one of the following methods is used on our range of premium spas:
Our Vortex, O2 and Arcadia spa ranges use this method. Under this system, the cabinet of the spa is insulated instead of the shell. This ensures that excess heat from the pumps and other equipment is trapped around the spa shell, reducing heating costs. This system has the added advantage of providing noise reduction meaning a quiet nights sleep and happy neighbors.
Full foam insulation
This is optional on our spa range. Using this method, the entire cavity between the spa shell and the cabinet is filled with foam giving additional heat retention properties. This method is often used in climates such as Scandanavia and Canada's, where temperatures can drop to 30 degrees below zero. Our experience has shown however, that the Australian climate does not suit full foam insulation has in our high summer temperatures, full foam insulation can lead to the spa overheating and being unusable. This is why we only offer this form of insulation as an option.
Efficient plumbing, better jets, and flow control are more important than horsepower. A lower horsepower pump in an efficient spa will produce just as much jet power as a higher horsepower pump in an inefficient spa. We work with our suppliers to ensure that all of our spas are plumbed to ensure maximum hydrotherapy benefits, whilst minimizing running costs.
Another consideration with the plumbing of a spa is the type of pipe work that is used. Most manufacturers will use a clear or braided clear tubing. We insist that our premium spa suppliers use flexible PVC pressure tubing. This type of tubing is especially designed for the hot, chemically treated water found in a spa and is guaranteed not to kink.
Water circulation / Filtration
There are basically three different methods of running the filtration in a spa.
The simplest method is to use a one-speed pump, which filters, heats and drives the water to the jets. This system uses the highest amount of power.
The second system employs a two-speed pump, which uses the pump’s lower speed to filter and heat, and the high speed to drive water to the jets. This system uses less power than a single speed pump.
The best system uses a dedicated one-speed pump to drive the jets and a smaller circulation pump to heat and filter. Not only does this method use the lowest amount of power for the highest amount of filtration, but also provides virtually silent running in heating and filtering modes. All spas within the Spa World premium spa range incorporate a circulation pump.
The control system is the brain of your spa. It controls the temperature, filtration cycles, pumps, blower, lights and sleep modes. All of our premium spas the use the most advanced control systems available. This is ensures that controlling your spa is simple and hassle free. All Vortex, O2 and Arcadia spas utilise cutting edge, SpaNet controllers.
There are two aspects to consider when designing the skimming system of a spa pool.
Firstly, it important that the skimmer system provides sufficient surface skimming to effectively remove contaminants from the spa’s water. As most contaminants that can make their way into a spa’s water float, the skimming of the spa’s surface is crucial in maintaining sparkling clear water. All Vortex, O2 and Arcadia spas use wide mouth weir skimmers.
The second consideration is how the skimming system is incorporated into the spa shell. Cutting the shell to install the skimming system will weaken the spa. For this reason, we insist on a molded skimmer system
Owning a spa shouldn’t be a hassle. All Spa World premium spas offer automatic sanitising systems which will reduce your chemical costs and the time spend keeping your spa water sparkling clean and fresh. Two types of automatic sanitising system are used.
Ozone has been used for years to sanitise water in spas, swimming pools and even water bottling plants. Ozone is a safe and effective way of keeping your spa water clean. However, because ozone can deteriorate the spa pillows and cover, it must be coupled to a mixing chamber. Many manufacturers skip this step as it adds cost to the manufacturing process. All Arcadia spas are fitted with ozone systems that include mixing chambers
UV sanitisation has all of the advantages of Ozone, but without any risk of damage to spa equipment. UV systems are now mandatory on public swimming pools in many areas of the United States due to their unsurpassed ability to kill viruses and bacteria. Our Vortex and O2 spas are currently the only spas available in Australia that uses this system.
Heat pumps are a fantastic way of reducing your spa's running costs. In fact, savings of up to 73% are not uncommon. However, there's a catch. Most heat pumps available for spas now days are not actually designed to work with spas. It is vital, that in choosing a heat pump for you spa, you check that it interfaces with the spa's control system. Currently, the only spa control system available that interfaces with heat pumps, are SpaNet's SV series controllers.The SV system allows you to fully control the heat pumps operation via the spa's touch pad. It also allows you to not only heat the spa, but also cool it - great in hot climates. Lastly, the Spa Net heat pumps will go through a proper shut down process before use. This is crucial for trouble free heat pump operation.
