Just think

If you’re using your hot tub for just 3 or 4 hours each week, why are you keeping it heated every hour, all week?

Want to heat the water already in your tub?

SUPA Heater can simply and easily heat the water in your tub using a self-priming pump and supplied hoses

Did you know?

For every 1°C of temperature lost and replaced by your hot tub heater to keep it warm, you’re paying approx. £0.36 and you’re not even using it - that’s day and night, forever!

How to hot fill your tub

SUPA Heater can fill your tub with hot water direct from your outside tap, even in the depths of winter - imagine that!

Home use

Do I need to leave my hot tub on throughout the week, when it's not really in use?

In short, no you don’t! Your SUPA heater can heat a 1,000L hot tub in approximately 1 hour, so when you’re not using it, switch it off and whip out the SUPA heater an hour or so before you want to jump into the tub.

Can I sit in the hot tub whilst SUPA is heating the water?

NEVER sit in the hot tub when SUPA is operating, as the water going back into the hot tub could be as high as 65°C, which could badly scald skin if left in contact for too long. Please heat the water to 40°C (when the temperature of the water passing out of SUPA shows 65°C, it will automatically switch off and your tub will be at 40°C). Always allow the water to be circulated for 30 seconds or so to ensure the hottest water is evenly dispersed.

When do you recommend I use the shower fitting?

Well really, it’s up to you. We recommend you shower before using your hot tub to keep the water clean and if you want to rinse off after getting out your hot tub to rinse away chlorine. It also comes in handy if you need to wash your dog, or if you fancy a spot of camping.

At what temperature should I set the water?

Great question – the British and Irish Spa and Hot Tub Association (BISHTA) recommends that you set hot tub water temperatures between 36°C and 37°C and never use a hot tub with a water temperature higher than 40°C. Remember to always supervise children when using a hot tub (the medical advice is to prevent children under four years of age from using the hot tub altogether).

Commercial use

How does SUPA heater handle heavy usage in commercial environments?

SUPA is built to last and uses high-quality components throughout. Whether you are heating water through recirculation in Mode 1 or where a direct hot tub fill straight from the mains is being adopted in Mode 2, both the heater and the pump have been designed to offer 90 minutes of continuous use before needing a short 15 minute ‘rest break’ between cycles, allowing the pump motor to cool and to ensure the heater is not left to run indefinitely when unobserved by accident. Typical short operating cycles of around 60 minutes, sufficient to heat a 4-person hot tub (allowing 250 litres per user) from 20-38°C, can be achieved multiple times during a change-over for holiday homes or lets from a single SUPA.

Can SUPA heater be used to heat pools?

SUPA has been designed to heat hot tubs up to 1,700 litres from 20 – 40°C in under 90 minutes, that is a very well-proportioned hot tub for 6-7 users and something previously unheard of from any other heating system. Whilst we do not recommend the use of SUPA for swimming pools, small above ground pools and swim spas of 4,250 litres or less, could be heated from 20 – 28°C by SUPA in 90 minutes. Watch this space and subscribe to hear of the latest news on one of our highly anticipated and market-changing developments, the SUPA XL, which will be able to heat a swim spa or above ground pool of 8,000 litres from 20 – 28°C in under 90 minutes.

Can I use the SUPA heater to clean my hot tubs?

Absolutely, you can use the benefits of hot water cleaning to get your tubs gleaming! In Mode 2, just attach your mains hose pipe into the front of the pump using a ‘Hozelock’ type quick-fit connector and attach our shower head or a pressure washer using the fast fitting on the outlet of the red ‘hot’ hose. Set the temperature you want in Mode 2 (typically below 40°C for pressure washers) and switch on the mains water – hey presto, instant hot water to help melt any grime away ensuring your hot tubs stay squeaky clean and inviting for each new guest.

Also, try using a pressure-washer with hot water to remove slippery moss from wooden decking and paving – it does the job to perfection! Or try melting snow and ice on slippery paths before using rock salt to ensure it doesn’t freeze over again, SUPA can really help in all sorts of previously unheard of ways.

How does SUPA streamline changeover days?

A SUPA heater simplifies your changeover days by swiftly heating your hot tubs in around an hour, something owners and operators know all too well has previously been the luxury of the major park owners with expansive boilers and hot water on tap. SUPA allows you and your team, however small, to efficiently prepare tubs for the next guests, reducing downtime and ensuring a warm and welcoming experience for arriving visitors every time.

After all the effort you put in as owners, getting the accommodation perfect for every arrival, SUPA heater ensures they enjoy a ‘hot’ tub and not just a ‘warm’ tub at check-in, helping you to retain those hard earned 4 and 5-star ratings you and your team have worked long and hard for.

For those of you with wood-fired hot tubs, its even better as you do not have to keep refilling the wood burner every 20 minutes for up to 4 hrs per changeover day, saving you a tremendous amount of time to do something more productive or relaxing!

And finally, SUPA quick changeovers allow you to get more occupancy, renting when you wouldn’t normally be able to due to time constraints and maximising revenue from your assets.
