Running a
hot tub needn't be expensive, or stressful. Having said that, if you're a hot tub owner or considering becoming one, energy consumption is likely to be a concern. but fear not, our 15 energy-saving tips are just what you need to ease your mind.
Efficient Heating Strategies
1. Optimise Temperature Settings:
Lowering your hot tub's temperature by just a few degrees (yes, just a few degrees!) can significantly decrease energy consumption without sacrificing comfort. Say you like your spa at a hot 38 Celsius, try dropping it to 37 for a week or two and see if you notice a difference, because your energy bills just might!
2. Watch Your Jets:
Jets are one of the best parts of hot tub use but for maximum energy efficiency it's important to consider how you use them. There are two types of jets in most hot tubs: air jets and water jets. Air jets are great at providing a gentler massage while water jets are a little stronger. Both are excellent at giving effective and relaxing massage but they also lower the temperature of your tub. Of course there is nothing wrong with enjoying your hot tubs massage jets - that's what they're there for! but being mindful of how you do so will help to keep energy costs low. If you are using the hot tub alone, adjust your settings so only your chairs jets are running. Minimise the run time of waterfalls and fountains too as these can also cool down the water.
3. Keep it Running:
Yes, keep it running! Here at direct hot tubs, we're often asked by our customers whether they need to turn their hot tub off completely to save energy. In theory, this might seem like the most sensible option. After all, it almost seems illogical that keeping something hot when not in use could be the more energy efficient option. Yet, it usually is. While it is equipped to do so, heating water up from scratch is hard work for your hot tubs heater and calls for a lot of energy. However, once the water is up to temperature, it will require far less energy to keep there. You will actually save more energy by keeping your hot tub on 24/7. Having said that, some people like to avoid use of their hot tub over the colder months. In such cases, we recommend performing a proper shut down or 'winterisation' of your hot tub. This involves emptying, cleaning and turning off the power. Though, If you enjoy using your hot tub throughout the colder months (we believe this is one of the best times to do so!) then by all means, keep it running!
Insulation and Covers
4. Use Quality Cover:
This is perhaps one of the most important considerations when it comes to hot tub energy consumption. A well-insulated cover is essential for preventing heat loss when your hot tub is not in use. It keeps the warmth trapped inside, reducing the need for constant heating. At Direct hot tubs, all our models are delivered with a high quality, insulated cover included. The covers have a fold in the centre so that one half can be opened for cleaning and water testing, keeping the water warmer.
5. Consider a Floating Thermal Blanket:
Adding an extra layer of insulation with a floating cover helps retain heat and minimises energy wastage. Floating covers sit on the water's surface to minimise heat loss. They are typically made of a waterproof, textured material similar to bubble wrap.
Energy-Efficient Equipment
6. Look for Modern Pumps and Heaters:
As technology advances and evolves, essential components like heaters and pumps become more energy efficient. If your hot tub is a very old model, it could be sapping energy unnecessarily. Consider upgrading the pump/heater to a more modern and energy efficient model if possible or upgrading your hot tub model altogether, the higher upfront cost could mean long term savings.
7. Use Technology to Your Advantage:
Modern hot tubs are often equipped with remote control technology. This technology is typically controlled by an app on your phone where you can monitor the temperature of the water amongst other various settings. With this technology, you'll be able to check things like temperature, water levels, chemical levels and filter cleanliness all while away from your hot tub. All of which are essential for a well run, energy efficient spa.
Regular Maintenance
8. Keep the Water Clean:
Keeping the water clean and sanitary is not only a health concern but an energy concern too. Regular chemical doses, water testing and cleaning ensure efficient operation and prevent clogs, thus reducing the strain on your hot tub's filtration and heating systems.
9. Address Wear and Damage Promptly:
Broken or ill functioning components, leaks and damage can all be detrimental to the health and energy efficiency of your hot tub. If you do spot any signs of damage, the best thing to do is to turn off and empty your hot tub temporarily until the problem can be checked/repaired. To prevent damage in the first place, yearly servicing is a wise investment.
Water Management
10. Monitor Water Levels:
Maintaining the optimal water level ensures your hot tub's pump operates efficiently, saving energy in the process. Most hot tubs will have a fill-line indicator. This is the level your hot tub should be filled to at all times when running. If the water drops below the required level, you could risk damage to your pump as it may take in air. Low water levels may also affect the filtration and heating system, all of which contribute to the overall performance and energy efficiency of your hot tub. The heavier your hot tub usage, the more you may see this line drop slightly so it's important to keep an eye on it this is another reason why remote apps are great as the software should alert you if the levels are too low.
11. Use Best Hygiene Practices:
achieving clean, clear and hygienic hot tub water needn't be tricky or tiresome. With a few simple practices, you can keep your water as clean as possible, for as long as possible. Doing so will mean that your hot tub's filtration system, pump system and heater all work efficiently. To keep your water clean:
• Avoid cosmetics in the hot tub: a quick shower with plain water before bathing will help eliminate any cosmetics from entering the water, ensuring your filter doesn't have to work as hard.
• Test levels regularly: testing hot tub water is a simple and quick process that takes minutes. Simply dip a test strip in the water to check sanitiser levels, ph and water hardness. All of which can be adjusted easily with the right chemicals. Regular testing will ensure water is balanced quickly and effectively.
12. Look for models with ozonators:
ozonators are advanced pieces of technology you may find in modern hot tub models. Ozonators offer a secondary method of water cleaning in addition to your typical sanitisers. This means cleaner water for longer, a reduction in need for chemical products and a reduction in need for filter changes.
Seasonal Considerations
13. Winterise the Hot Tub:
If you don't plan to use your hot tub during the winter months, consider shutting it down to save on energy costs. winterising is a simple process that requires emptying the hot tub and leaving it in a clean, protected state during the winter months. If you choose to winterise you will not only save on energy costs, but chemical and cleaning costs too.
14. Adjust Heating Settings in Summer:
Hot tubs can be enjoyed year-round and summer is no exception. WHen it's hot out, try turning down your hot tubs thermostat for a more comfortable and energy efficient bathing temperature.
Typical Usage Tips
15. Limit Soaking Time:
Long, leisurely hot tub sessions may sound luxurious but minimising bathing time could be more beneficial for several reasons. Spending too long in your hot tub could pose certain health risks, while shorter hot tub sessions can actually be more beneficial. In addition, limiting hot tub soaking time can help to reduce heat loss and therefore energy consumption.
By implementing these simple yet effective strategies, you can significantly reduce your hot tub's running costs without compromising on comfort. Enjoy the luxury of your home hot tub while saving money and energy!
