How Do Hot Tub Air Source Heat Pumps Work?
An air source heat pump extracts heat from the outside air through a series of tubes containing eco-friendly R32 refrigerant. As the outside air flows over the tubes, it warms the refrigerant, converting it from liquid to gas.
This gas is then pushed through a compressor, increasing its pressure and significantly raising its temperature. The heated gas passes through a titanium heat exchanger.
Your hot tub’s water circulation system is connected to the air source heat pump. As the heat from the gas travels through the heat exchanger, it heats the water in the pipes.
The refrigerant cools down, reverts to liquid form, and the process repeats.
Will an Air Source Heat Pump Work on My Hot Tub in Winter?
Absolutely! Due to the way hot tub air source heat pumps operate, they continue to generate heat for your hot tub’s water system even when ambient temperatures drop below zero degrees. This is because the compression of the refrigerant produces heat. Be aware that some cheaper air source heat pumps do not function below zero and may be ineffective in colder winter months. All of our models are designed to work efficiently at temperatures well below zero degrees.
This method is not only cost-effective in the long term but also more environmentally friendly.
From the delivery service & building work to the finished product in action - a truly faultless process.
Sauna looks amazing, heats up quickly & is super easy to use.
So worth it and couldn’t recommend Heracles any more!!
Fantastic garden sauna.
We boutht the sauna end of August and arrived early September as scheduled with us. It was easy to built and took us one day to built the sauna and couple more days to install the door, roof, paint inside/outside and install the benches. We then had the electrician to connect the heater, and Camilla Sauna was ready to use.
As mentioned by other customers, it heats up quickly, smells wanderful, and fits 4-5 people easily.
It is a great experience, we all enjoy it very much, even our kids.
I truly recommend to anyone.
Really enjoying our Camilla sauna. Being smaller than a barrel sauna it heats up quickly, but inside there is still plenty of space for 4 people.
Very easy to use and gives a great sauna experience!
I bought this a couple of months ago, and my only regret is that I didn’t get one years ago.
I honestly cannot recommend this enough. It heats up quickly and is incredibly relaxing and peaceful once you’re inside.
It has two different levels and you can configure the internal seating a number of ways. Either way, it’s easily enough to fit two adults long down (if one person has their knees bent). Or you could happily fit four people sitting (five at a push).
The sauna smells wonderful and is incredibly well insulated, meaning it is HOT in about 20 minutes - and you can turn the heater off once you’re about half way through and it will still stay super hot for another 20-30 minutes (saving on energy costs).
I have a smart meter, and testing it - the sauna costs less for an hour on a hot setting than it costs to dry a load of washing in the tumble dryer.
The sauna took two builders two days to construct, plus a day for the electrician. In the end we put the lights on a separate circuit from the heater but you can run both off the same one if you wanted to.
The only downside were the instructions which were frustratingly vague, and the fact that you have to oil the sauna inside and out before using it. It would have been useful to know this before we had put the seats in. From speaking to Keith - the instructions are in the process of being redrafted which would help.
One more thing to mention - every single part is individually labelled which really helped with the build, so even though the instructions were a bit convoluted we got there in the end :)
Throughout the process Keith was incredibly helpful, patient and remained charming even when I was firing off questions three times a day (thank you Keith!!)
All in all I cannot recommend this enough. It is also amazing for my mental wellbeing, for helping with lots of deep restful sleep and just overall wellness.
Top tip - I also installed a dip tank next to the sauna for the full hot / cold experience, I’d also recommend this if you can run water to wherever the sauna is, it really does add to the experience.
If you have read this far, the only thing left to say is BUY ONE. You won’t regret it.

I wasn't totally sold on the hot tub idea, but I really enjoy spending time in it. Keith and team did a great job in sorting out the one that best suited our needs and aftercare has been great as well. Would definitely use them again for my next one :).
We recently purchased the hot tub and weren't 100% sure who to buy from. Keith reassured me on what they offer as a company and we decided to buy. What a great hot tub, great value, great service and the installation is a must in my eyes. The delivery team we perfect gents and nothing was too much for them. All round we're very, very happy and highly recommend this company. Thank you. Lee
Delighted with this hot tub, mainly for the two of us but very popular when the family visit. Got some nice features. Perfect for us.
Incredibly happy with my sauna. I’ve owned home saunas before and the quality of this product is far superior to others and at a very competitive price point. The team and Heracles Welness were incredibly helpful, supportive and easy to reach from point of order onwards. Always available on the phone to assist with the build. Very professional and easy to deal with. Five start service.
Would thoroughly recommend Keith and his team for any future sauna needs! Couldn’t have been more helpful and answered every question raised. Too advice from start to finish!
I bought this for my friend and they are happy. Amazing product, they didn't expect. Super easy to use, i think that's the main point these days when people having too many things to control and keep in their heads. So very pleased with this model, correct choice!
Many thanks for you support!
Kind regards, Olga.
I bought this hot tub a month ago, and have had no issues. Really lovely colour, and seating arrangement.
Would recommend.
