10 Ways To Reduce Hot Tub Running Costs

There are many easy ways you can reduce your hot tub running costs. From choosing the right place to position your hot tub, to keeping on top of chemicals to cleaning your hot tub’s filters regularly, we’ve put together 10 simple ways to manage and improve your hot tub running costs.

If you're thinking about energy costs, Lay-Z-Spa is the best choice having been proven to be the most energy-efficient inflatable hot tub brand. An independent study of comparable products by comparable brands found that Lay-Z-Spa hot tubs heat faster, use less energy to maintain a certain temperature, and are better at keeping the heat in. Overall, this could save you up to £620 a year. Find out more.

1. Leave Your Lay-Z-Spa Heater Activated Between Uses

If you use your Lay-Z-Spa often, say 3 or more times a week on different days, it is more cost-effective to keep the heater set to one temperature. Dropping the temperature and turning it up again will consume more energy than keeping it steady at a steady temperature.

If you use your Lay-Z-Spa quite irregularly say 2 or less times and on sporadic days of the week, you might want to consider dropping the temperature to somewhere between 25°C and 30°C between uses.

If you only use your Lay-Z-Spa at the weekend or for 2 consecutive days, the best way to reduce your hot tub running costs is to heat up for your first day of use, keep the temperature set for the next 2 days and then turn off after your final hot tub session. For example: Start the heater and set youir temperature on the Friday evening, keep it set at your desired temperature throughout Saturday and Sunday then turn off the heat when finished using it on the Sunday.

Lay-Z-Spa heaters are thermostatically regulated, so they will only switch on to top up the temperature of the water to whatever temperature that you set. This is better than letting the temperature rise and fall a great amount, which could result in more energy usage. Please be aware of the ambient air temperature, as at colder times of year more energy will be required to keep the water warm.

Note: A Lay-Z-Spa heater uses 2050W per hour whilst on the heat setting and 600W whilst running the inflation / massage function. We therefore recommend contacting your energy supplier to determine your running costs and tariff to help ensure you are using your hot tub economically.

2. Use Your Lid And Top Cover To Keep The Heat In

Heat rises and one of the biggest causes of heat loss in hot tubs is straight from the water's surface where it means the outside air.

We strongly recommend making sure the protective top cover and the insulating inflatable lid is firmly fastened in place when you are not using your hot tub and when heating up the water. The lid creates a thermal barrier that helps prevent hot tub heat loss.

Lay-Z-Spa hot tubs all come with a cover and inflatable lid as standard to help with heat retention and to stop debris from falling in.

If your inflatable lid or top cover is damaged or lost please visit Lay-Z-Spa Spare Parts for a replacement.

3. Save Money With A Chemical And Filter Bundle

To keep your hot tub in great condition, chemicals and regular filter changes are an absolute must. Chemical maintenance of a Lay-Z-Spa is actually really easy once you get the hang of it and it's best to always have the chemicals you need. Thanks to our bundles, getting chemicals and multipacks of filters is cheaper than you might think!

If you are unsure what hot tub chemicals you need or what they do, visit our Chemicals Guide.

4. Position Your Hot Tub Near Windbreak Or In A Shelter

Setting up your Lay-Z-Spa in an area with a windbreak or in a sheltered area helps to prevent wind chill. Wind exposure can rapidly reduce water temperature and something as simple as placing your hot tub next to a fence can form an effective shield.

If you don't have a natural windbreak or don't want to make a permanent shelter, we recommend the Lay-Z-Spa dome. It offers privacy, protection against the elements and you can pack it away when it is not needed.

Shelters, gazebos and pergolas help with preventing heat loss and provide privacy, why not explore some of our favourite hot tub gazebos and shelters hot tub for some inspiration.

5. Insulate Your Lay-Z-Spa

We see many Lay-Z-Spa owners creating their own insulating covers, bases and even completely insulated surrounds. These are great for keeping your Lay-Z-Spa warm and saving energy. There are many different ways of doing this and a variety of materials available. Join our Lay-Z-Spa group for tips, inspiration and to see what others have done.

There is also a range of off-the-shelf inflatable hot tub thermal covers on the market to help insulate your Lay-Z-Spa. Although we don't have a Lay-Z-Spa winter cover just yet, we have received great feedback on insulating covers from CWTCHY covers.

Top tip: the Lay-Z-Spa Floor Protector is great to insulate the base of your hot tub and protects against abrasions and damage caused by rougher surfaces.

6. Clean Your Hot Tub Filters

Keeping your hot tub's filters clean will not only prolong their life but also make your pump more efficient. With regular cleaning, you can keep using your Lay-Z-Spa filters time and time again.

Not cleaning your filters can result in a build-up of debris which can result in poor water flow. The pump will therefore have to work twice as hard to filtrate the water, which may cause increased energy usage. Find out more about hot tub filter care.

Make your hot tub more energy efficient and save money.

7. Make Use Of Your Power Saving Timer

If you don’t use your hot tub regularly, the Power Saving Timer is great for keeping your Lay-Z-Spa running costs to a minimum.

The Power Saving Timer prevents any unnecessary use of power. It allows you to set the time and duration of the heating cycle so that you can enjoy your hot tub at a time of your choosing without having to leave your Lay-Z-Spa heater on at all times.

Top tip: Pumps with Wifi can be scheduled using the Lay-Z-Spa App. This gives you the freedom of being able to set your temperature even if you're not home. Again, this means you don't have to leave your heater on all the time.

8. Fill Your Lay-Z-Spa With Water From The Hot Tap

A simple but effective way to save money when filing your hot tub is to use water from the hot tap mixed, with a little cold at the start. It is far more energy-efficient to start your hot tub with warm water (ensure the water is no hotter than 40°C and that you have added a thin layer of cold water to the spa first) rather than filling the hot tub with cold water and waiting for the pump's heater to do all the work.

Additionally, if you don’t require your spa to be as full as possible then consider filling it up to the minimum line. This will save on both the initial water cost as well as the continuous cost of heating the spa water.

Use your Lay-Z-Spa power-saving timer to reduce hot tub running costs.

9. Monitor Your Energy Provider Rates

If you find you have taken appropriate measures to place your Lay-Z-Spa in a sheltered location, are on top care and maintenance and followed other steps to keep energy consumption low but your energy bills are still high - You can find advice on the OfGem website.

10. Get a Lay-Z-Spa with an EnergySense™ Liner

Currently only available on the Zurich AirJet™ and Barbados AirJet™, the EnergySense™ liner is an in-built thermal cover. It has a double layer of aluminium foil and foam wrapped between our tough and durable DuraPlus™ outer making it 40% more energy efficient when compared to similar hot tubs. The insulating layer means that it heats up quicker and it holds the heat in better and therefore saves on energy costs.
