Can I run my spa on an extension lead?

No, your spa must have a dedicated power supply provided by a licensed electrician in line with local and national regulations.

Do I need a hardcover for my spa?

Your spa needs to be covered when not in use, the cover that Spa World™ supplies is lockable and provides a high level of insulation. This has a great impact in reducing running costs of the spa. Leaving an empty spa uncovered and exposed to the sun will damage the acrylic and this is not covered under warranty.

I am allergic to chlorine or don’t like the smell of chlorine – Can I use salt in my spa pool?

Yes, we are able to offer salt systems for swim spas, however there are also other solutions such as peroxide based chemicals that may be better suited for you. Visit our learning centre for more information.

Can I choose the design or layout of jets in my spa?

No, this is not a possibility because the spas are designed and engineered to function for optimum performance and meet the relevant regulations.

Can I leave a spa pool empty?

Yes, you can leave however you must follow a shut down procedure in your manual and ensure that the hardover is in place to reduce the effects of direct sunlight or too much heat on the spa shell whilst empty. As mentioned earlier, leaving an empty spa uncovered and exposed to the sun will damage the acrylic and this is not covered under warranty.

Can I have a cold spa in summer?

Yes, the only issue you may face is if the temperature is 40c outside, the temperature of the spa water will still be high due to ambient temperature. If you truly want a cool spa in summer, you may need to purchase an optional heat pump which can both heat and cool the spa water. Heat pumps can also save up to 70% on spa heating costs compared to electric heaters.

Can I install a spa pool inside my house?

Yes it is possible to install a spa pool inside a house if the spa’s destination point is accessible. We recommend that you ensure you have a good ventilation system and drainage system in case the spa pool was to ever develop a leak.

Can I turn my spa off when not in use?

The short answer is yes, however we strongly advise against doing this. That’s because the spas are designed to filter and heat when not in use, but turning them off you will not have filtration and your water will need to be replaced or treated excessively in order to be safe.
