Hot Tub Filter
The
hot tub filter is a vital component within your hot tubs system. Most hot tubs contain one filter, but larger models may be fitted with two filters. The
filters job is to trap large contaminant particles and prevent them from circulating through the hot tub's system. Hot tub filters draw out the dirt you can't see as well as larger particles of dirt and debris. Not only does the
hot tub filter draw out dirt and debris but other harmful contaminants that can interfere with the clarity of the water such as cosmetics and detergents.
Hot Tub Pump
The standard hot tub contains two
hot tub pumps. Each
hot tub pump is responsible for a different role in the hot tub's circulatory system. The first
pump is the main pump and circulates water through the heater and filter to keep the water hot and clean. The second pump supplies water or air to the hot tubs jets. The second pump is only activated when the jets are switched on.
The main
hot tub pump is the most important of the two as water circulation helps to keep the spa clean. Without the circulation pump the water would remain stagnant and become unsanitary. Running the pump regularly also helps to keep the temperature even and constant. Without regular circulation, your hot tub could develop cold spots. Your hot tubs pump works to continue circulating water around twice a day in two to four hour cycles. The hot tub will activate the circulatory pump automatically whether the tub is in use or not. Some hot tubs however may be fitted with an energy efficient pump which runs 24 hours a day.
Heating Element
Every hot tub requires a means of heating the water. In most modern hot tubs this is an electrically powered heating element. The pump runs the water through the heating element and circulates it around the spa.
Not all hot tubs use electrical heating elements. Some hot tubs may use a solar powered, wood powered or gas powered heater.
Hot Tub Jets
Hard shell
hot tubs are fitted with jets. These jets pump water and air into the hot tub which creates the massage experience hot tub users love. Most hot tubs are equipped with two types of jets: high pressure pin jets and low pressure massage jets. The high pressure pin jets are smaller in diameter and push out less water. However, the high pressure still feels good on the skin. Low pressure high flow jets on the other hand are thought to offer a more effective massage, with the theory the higher water flow is able to stimulate below the derma layer. Therefore, when it comes to hot tubs, it is not the amount of jets fitted that will offer the best experience, but rather the quality of each jet.
Jets are what make it a hot tub! Without jets, a hot tub would just be a warm, outdoor bath! Different types of hot tubs are equipped with different types of jets. Inflatable hot tubs may just have air inlet holes which allow air bubbles into the water. Hard shell hot tubs on the other hand are typically fitted with a mixture of water and air jets which can be adjusted to provide streams of different intensity.
The two types of jets used in hard shell hot tubs are low pressure and high pressure jets or 'pin jets'.
High pressure pin jets
high pressure pin jets offer a more controlled flow of water due to their smaller jet hole size. In theory, these jets provide a deeper massage due to their higher pressure which is thought to stimulate below the skins derma layer.
Low Pressure High/Low Flow Jets
Some people find the high pressure pin jets too intense, in which case the low pressure jets can provide a gentler massage. Low pressure jets allow a softer flow of water due to larger nozzle holes. However, low pressure jets with a high water flow can also provide an effective massage.
