Advanced, energy-efficient spa heating built for performance, durability, and year-round savings.
Keeping your hot tub at the perfect temperature shouldn’t cost the earth — literally or financially. The spanet Eco Cube is a high-performance inverter heat pump that offers a smarter, more sustainable way to heat your spa, with industry-leading efficiency and whisper-quiet operation.
Whether you’re using your spa daily or occasionally, this technology ensures you always have warm, inviting water with minimal energy use.
Unlike traditional electric heaters, the EcoCube draws heat from the surrounding air, working more efficiently even in lower UK temperatures.
Here’s what makes it stand out:
Up to 75% energy savings compared to standard spa heaters
Frost protection & winter-ready for year-round performance
Eco-friendly R32 refrigerant for reduced environmental impact
The UK climate demands heating systems that can cope with cold spells, dampness, and fluctuating outdoor conditions. The EcoCube is engineered specifically for this — offering reliable warmth, even in winter.
What UK users appreciate:
Rain or shine, the EcoCube delivers heat you can count on.
What sets EcoCube apart is how quietly it works. Thanks to its variable-speed fan and brushless DC motor, you’ll barely hear it running — even while it’s saving you money.
Ideal for homes where noise is a concern
Doesn’t interrupt peaceful spa sessions
Uses far less electricity than electric-only systems
Read how UK spa owners are enjoying warmer water, lower bills, and quieter nights with SpaNET EcoCube technology.
EXCELLENT Based on 114 reviews Posted on Rodney MainTrustindex verifies that the original source of the review is Google. Bought a Hottub from Heavenly hottubs… Bought a Hottub from Heavenly hottubs last September( 2024), I found the company could not do enough for us appointments were kept and after several months of use we decided to get a heatpump installed, again everything was explained to me by Jon the owner, he was very prompt and efficient. Today was the yearly service that we opted in for, Eillie ( apologies if I've spelt it wrong ) carried out the service, she was very thorough and cleaned and maintained the hottub filters, pipes, internals, and all external fittings. This company is a family run business and are very customer focused, from my experience in any dealings with them I only have praise for their service and their determination to customer satisfactionPosted on William LyonTrustindex verifies that the original source of the review is Google. Bought a hot tub for our holiday let from Heavenly Hot Tubs. From start to finish it was simple and easy. Many thanks to Jon and the team for a seamless install even if they did have to travel all the way to Aberdeenshire to install it. Made sure we had all the right advice on set up and maintenance. 100% will be using these guys in the future.Posted on Liz HolmesTrustindex verifies that the original source of the review is Google.

Great service from a family run company . From initial contact to install I could not fault heavenly hot tubs . No hard sell and asked exactly what we wanted and recommended a few things to make our hot tub amazing. On delivery day we were there to help move it around and get into place and gave us pointers etc on how to use and get the best from our tub! Thanks for such an amazing experience and made us feel valued. More than 5 star company! Can’t recommend enough.Posted on Sharon WrightTrustindex verifies that the original source of the review is Google. Fantastic service ,would highly recommendPosted on Fiona MorrisonTrustindex verifies that the original source of the review is Google. We had excellent service from beginning to end with Heavenly Hot Tubs and Swim Spas. We had to change our delivery date due to the garden renovation not finishing on time and then had to dash away during handover so another time was arranged for Jon to come over and show us the ropes. We got an air source heat pump fitted which has reduced running costs significantly and we could not be happier with our Vortex Cobalt swim spa. Service was excellent and we love relaxing in our new hot tub.Posted on Matthew Mc MullenTrustindex verifies that the original source of the review is Google. My wife and I found heavenly hot tubs on a Saturday morning after a quick Google search for hottubs showroom near us. We where surprised at the amount of hottub on show when we arrived l. After travelling around Dundee, Edinburgh and other cities we found the hottub that we where looking forward 10 minutes away from our house. A family ran business without any nonsense when we where looking around. Straight forward knowledge answers to any questions we had from Heather and Jon. We picked our hottub within 10 minutes and luckily it was already in stock and was delivered and set up by Jon within a week. Came with everything we needed to get started a d some recommendations to make it easier to manage.. couldn't fault anything from this company.. was a pleasure to deal with from Start to finish.Posted on C EastonTrustindex verifies that the original source of the review is Google. Very professional, family run company. We had a great experience from start to finish. Heather was so helpful and knowledgeable and helped us choose the right hot tub for our needs. Delivery and installation went really smoothly. We now have a lovely place to unwind after a hard day at work. I would highly recommend buying from this company.
