Hot Tubs, what to know
June 29, 2022 Johnsons


Before dipping your toe in the Hot Tub market there are a few things you might like to know.

Hot tub jets convert the water flow from the hot tub pumps and plumbing system into a massaging action. Hot tub jets have three main connections that are in the water, the air in and an air mixture outlet. Internal valves also play a key role in pushing water through to and out of the jet. The internal valves have varying sizes with corresponding responsibilities linked to the jets.

Smaller jets are called air venturi valves and provide an air passage to supply the jets. Larger valves are responsible for moving the water to provide various therapeutic massage capabilities from the jets. The rear of the jet is the diffuser that holds the jet into the hot tub.

Rotary jets move the water around in a circular motion massage a wider area. Moving massage jets direct water up and down as well as horizontally to provide you with a relaxing moving massage experience. Directional jets are the most common type of hot tub jet providing targeted hydrotherapy massage. Ideally, your hot tub should provide you with a combination of jet types to not only provide you with a choice of functionality, but also various hydrotherapeutic benefits linked to regular hot tub use.

You may come across some Hot Tubs that incorporate air blowers. These are plumbed to many air jets around the hot tub. When these are switched on, the air system produces the typical jacuzzi bubbling water effect.

The pump system installed within the hot tub shell plays an essential role in the effectiveness of hot tub jets. This drives the water through the jets and so, as part of your hot tub jet research, you should also aim to discover how many hydrotherapy pumps are incorporated into your prospective hot tub purchase. This will allow you to assess if they can then facilitate advanced jet hydrotherapy and airflow provision effectively.

Hot tubs in the higher price brackets generally have a significantly larger jet and pump count. Generally, you should expect to pay a much higher price for greater levels of premium hydrotherapy jets and hydrotherapy pumps functionality.

When you buy a cheap hot tub, its resale value drops to zero as soon as it arrives in your garden, its lifespan will tend to be short, and it will typically be expensive to run. As you go up the pricing ladder and start looking at hot tubs from reliable spa manufacturers, the build quality tends to improve, the lifespan will be longer, residual values will be higher, reliability will be better and running costs will be lower.

So, how much does a hot tub cost? You need to look much further than the price tag to answer that. For example, if you buy a poorly manufactured hot tub for £2,500 but it breaks down after 12 months and spare parts aren’t readily available to fix it, the cost of ownership is £2,500 a year plus any costs related to having to pay to have it taken away and repaired. On the other hand, if you pay £10,000 for a quality hot tub from a reputable manufacturer and it lasts 10 years, then you trade it in for £3,000 after 10 years, the cost of ownership is just £700 per year. In these terms, it makes more long-term financial sense to go for the more expensive hot tub despite the higher initial price tag.

Hot tub build quality can vary enormously, so look out for the following signs of good build quality:

  • Shell construction with multiple layers for strength and long-term integrity of the shell surface and structure.
  • Sub-frame manufactured from treated timber or metals that are rust-resistant for long-term strength and durability.
  • Cabinetry should be of either weather-resistant synthetic material or treated hardwood construction. Softwood should be avoided at all costs as it will quickly rot.
  • High-quality insulation materials that will maximize heat retention and keep energy costs down.

Just some of the fundamentals to consider when purchasing your Hot Tub.
