How many jets is it best for a spa to have? 

The quantity of jets in a spa is not the most important factor for the best performance. The hydro massage will not necessarily be more efficient, nor the bubbles more pleasurable, although many customers believe that it is better to have more jets. What really matters is the type of jet installed, the quality of the materials, with which it has been constructed and its orientation and power. There are spas by other brands on the market that have dozens of cheap, small jets, that serve only to impress uninformed clients through their sheer number. For so many small jets to operate minimally, a spa requires more powerful filters, which consume more energy due to the loss of friction, and result in large electrical bills. As well as being inefficient, these spas have so many protuberances in the surface area of the spa that they can be very uncomfortable. The importance of the water stream compared to the jet. When a spa is designed, the water stream is the starting point as a force that exerts pressure and is directed towards a point in space, generally the body, in which it produces a beneficial effect. The flowrate, pressure and possibility of directing or regulating the stream are elements controlled by the jets. For this reason, a spa should not have more jets than necessary for its hydrotherapeutic function. These should be installed so as not to cause discomfort to the back and the rest of the body when the user wishes to enjoy a relaxing bath of bubbles, and they should be designed for optimal energy efficiency. How should the number of water streams be compared? Before investing in a spa, the number of jets can be compared to find out whether it is adequate or artificially inflated to impress unsuspecting customers. Examining technical sheets about the spas to see whether they meet the needs in terms of the number of seats or space, the electrical consumption can be divided by the number of jets. The strength of the massage filter can then be divided by the number of jets. The lowest figure in the first calculation will be the most efficient and the highest in the second calculation, the most powerful. The most balanced model will be the one with only the necessary number of jets. All Aquavia Spa models excel in this respect. Also, thanks to their excellent design, they offer a vigorous yet soft massage, without additional or non-useful jets, and with more tranquil massage areas for people who simply wish to enjoy the bath, resting and relaxing in the water.

How powerful should a good spa be?

Spas have different electrical filters for different uses. The power that should be compared before choosing a good spa relates to the massage filters and the blower filters, which emit pressurised water through the available jets and air nozzles.

The use of more power than that strictly necessary only involves a waste of energy.
The best way to compare the strength of spas, before deciding on investment, is to take the tables of specifications of each one and divide the power of the massage filter and air nozzle by the quantity of jets and air nozzles available. Immediately afterwards, the electrical consumption of each filter should be divided by the number of jets and air nozzles. The best spa will be the one that is most balanced in terms of both calculations. This means that the best spa will have an average consumption of electricity per jet and air nozzle and an average power output per jet and air nozzle that is not towards the extreme end in either comparison and will, therefore, offer the necessary power to provide a vigorous, pleasurable massage without excessive energy consumption levels.
Conversion of units
Prior to the comparative test, it is necessary to convert the units of power of the potential spas. The presentation of technical information on filters is not standardised, so classifications of power could be in different units (kW, hp?). Some manufacturers look for units that transmit the idea of great power, but later turn out to be wasteful.

How do you choose the best location for a spa?

Although all Aquavia Spa models can be installed both indoors and outdoors, as a general rule, owners choose an outdoor location for their spa: a garden or terrace. The size of the chosen spa is determined by the space available and the number of people who will use it simultaneously.

Choosing an external space may sound easy in principle. In a large garden, a spa could be placed anywhere. However, other factors have to be taken into account: privacy, ease of access for spa users, distance from electrical outlets?

A tip: draw the space on the ground.
Before choosing the spa model that is appropriate for your needs and chosen location, the best option is to gain an idea of how it will look in the chosen area. This can be achieved using rope or a garden hose and drawing the base and dimensions of the spa on the ground. Once within the space that the spa would occupy hypothetically, it is possible to observe whether users would be visible from outside the garden, from neighbours’ houses, from neighbouring buildings, even from the house itself, in order to determine the level of privacy.

It is also important to observe whether users can get in and out easily, without detours, and whether electrical connections and plumbing are nearby. If the result is not to your liking, you can draw the outline of the spa elsewhere in your garden or terrace.

How deep should a good spa be?

The width and length dimensions or diameter of a spa depend on the available space and the number of seats. Once the size of the spa and the number of seats have been decided, it is important to ensure that the model is deep enough before purchasing the spa.

It is necessary to compare potential spas and look closely at the height dimensions. The majority of Aquavia Spa models measure 90 centimetres in height, as in the image, compared to other brands that range between 70 and 85 centimetres.

Significant depth, such as in Aquavia Spa models, ensure that the user’s torso remains submerged when reclining on the loungers, optimising the body’s centre of gravity with the feet slightly raised. This prevents the user floating away from the lounger and losing the hydro massage effect and personal comfort.

The same effect occurs when seated. With no loss of comfort, Aquavia Spa ensures greater immersion of the user, even when people are very tall.

Production costs
A spa of 90 centimetres in height is recommended, as it ensures adequate depth and complete satisfaction in terms of the investment. It is important to remember that spas lower in height require fewer production materials and have fewer costs. In comparison, a spa that has been economical with material is much more expensive than one that is adapted to the real proportions of the owners.

Comparing technical files is helpful in choosing a spa, with the exterior dimensions and maximum depth. It can also be useful to obtain images and videos of spas installed and in use.

If the torso is naturally covered by water, the spa dimensions will be adequate.
