Firstly, we need to look at the specific costs of running a spa.....
A good place to start considering hot tubs wouldn't exist without its presence. With most houses in the UK expected to have water meters fitted within the near future, the days of relaxed water usage are over. With hot tubs averaging a water capacity of 1000 litres, the filling and re-filling of spas can be expensive, especially as draining is recommended every 3 months. However, water costs, in comparison to chemical and electricity costs are relatively low.
With an average hot tub running two pumps and a 3kw heater, clearly electricity is the main cost in the running of a spa. Most hot tubs have two, two hour filter cycles every day and this is separate to the running of the pump when the spa is heating. The main electrical requirement is the 3kw heater, however once the hot tub has reached temperature, this cuts out, therefore, the most expensive time on a hot tub, is the re-fill period, where the temperature rises for a period between 15 & 20 hours. The most effective way to save on this cost is to ensure your spa cover is in top condition and not waterlogged, as this can lead to heat loss, which requires the heater to kick in.
This cost has significantly decreased in the last 10 years, as chemical prices have dipped. However, it is still key to consider the costs of maintenance products. This cost really depends on what the hot tub is maintained with, is it chlorine, bromine or a chemical-free system such as Aquagarde. Chlorine is the cheapest sanitiser to run your spa on, and a 5kg tub of granules can last 2 years if used correctly, this is the main chemical needed to ensure water safety. Bromine is the second cheapest, but significantly more than chlorine due to less popularity and its softer touch on the skin. Chlorine-free systems such as Aquagarde & Aquafinesse are significantly more expensive compared to the standard sanitisers of bromine and chlorine, simply because the technology contained in them is unique. Other water chemicals, which assist the standard sanitisers are not strictly required but products such as No Foam can make maintenance easier. Generally, chemical costs are less when you shop around and do not get fooled into the "unofficial chemicals will invalidate warranty" scam. This scam is so easy to be fooled into as a new hot tub owner, but it has no ground to be based on, most chemicals come from the same factory in South Africa, this factory simply re-labels the products to the appropriate brand.
