SUPA Heater – World’s Fastest Portable Heater for Hot Tub & Above Ground Pool Heater. for Domestic and Commercial Use. Digital Heating Control, Propane Fuelled to Deliver SUPA Fast Heat Up Times
SUPA
Why we love it
Multifunctional and instant heating solution.
Drastically cuts hot tub warming time.
Significant energy and money saver.
Main Highlights
SUPA HEATER: SUPA isn’t just for hot tubs where it recirculates the water already in your tub up to 15 x faster than your built-in heater — it can also instantly heat mains cold water straight from your outdoor tap to refill your tub at your required temperature. It can also be used to take an outdoor shower, clean the car, rinse the patio, or even wash your dog. It also converts your standard jet washer into a high-temperature, dirt and grime busting SUPA hero.
SAVES YOU TIME: Perfect for glamping sites, Airbnb’s, and holiday parks enabling 3-4 hot tubs to be fully heated from fresh, cold water to 400C during change-over.
SUPA PERFORMANCE: Ready for a soak in under an hour? SUPA can raise a 1,000-litre hot tub water by 1°C every 2 ¾ minutes, not every 60-90 minutes! That kind of heating power means you can reheat a cooling tub from 37 to 40°C in less than 10 minutes, even in the depths of winter, so you can enjoy your tub hot, not a warm tub, for as long as you want.
SAVES YOU MONEY: Heat only when you need to. Traditional systems waste £££’s keeping tubs warm 24/7. SUPA heats on demand, meaning you only pay for heat when you use your tub – think of it as ‘pay as you go’! Why pay to keep your tub heated 168 hrs a week if your only in it for 3 of them? A recent survey of SUPA Heater owners said they saved an average of £573 a year and over 33% are saving over £660! That’s not just smart… that’s SUPA!
BETTER FOR THE PLANET: SUPA eliminates the constant energy drain and CO₂ output of traditional hot-tub heating. You wouldn’t keep the bath full and hot all week just in case — so why do it with your tub? By heating only when needed, you cut waste and carbon emissions while still enjoying perfect comfort on demand.
INCLUDES: Heater, self-priming pump, hoses, gas connection kit and shower head, in fact everything you need except for the gas.
