Recommend this product (OKU panels) without hesitations, easy to install great, low-pressure system. Quick delivery from the date of purchase. Installed in one weekend, pool temp increased by 3 degrees in the first day—the most efficient high volume solar heating I have come across. I will also add that it's extremely strong and durable.

I recently purchased the OKU Solar Pool Heating System ... If you are handy, this is a great product and I recommend purchasing from EcoOnline. I got quotes from various pool heating products (Gas, Electric, Solar, Tube, etc.) and the price was significantly higher, with more operating costs.

The pool heating was exactly what I wanted and ordered, arriving quicker than expected and working better than expected. They were easy to install and have worked faultlessly ever since.

Bought a 4-panel system in 2012, yes that's 7 years ago... I've sat back and enjoyed a heated spa FREE. It has easily paid for itself. The panels show no sign of deterioration. Very happy ... The only downer is that winter months don't keep water temp at constant high 30's degree C. Recommend EcoOnline ... absolutely.

The quality of the supplied parts was excellent. The kit heats the spa to 40 degrees, which is a bit too warm. Throttling the valve on the return pipe makes the thermal cut out trip a bit earlier. It takes a bit more forward planning to use the system, but I’m more than happy with this compromise when most of the time, the spa is heated for free.

Purchased a solar pool system with 22 panels and it does a great job at keeping my pool warm. I would recommend both the OKU panels and EcoOnline.

Purchased a 4-panel kit for the swim spa. Easy to install. Had a minor issue which was resolved with a phone call. The swim spa usually heats to 27 - 32 degrees C with no running cost due to the solar-powered pump. Added 2 additional panels to keep the pool a bit warmer.

Due to increasing power costs, we chose an EcoOnline system to reduce them. Easy to install with the directions supplied and running as efficiently and effectively as claimed. Enjoying the spa all year round with the sun doing all the heating.

Panel installation was quite logical and went reasonably well. Got our goods quickly with no problems. The panels have helped to heat our spa and reduced our electricity bill, so all good. So glad we found this product.

Very pleased with this purchase of solar pool heating mats. It came with great instructions for DIY install and was all for a really good price. Customer service was excellent and a few missing parts were sent via overnight delivery. Highly recommend buying from EcoOnline.

I have these (OKU panels) for 3 years and would recommend this. I use them to heat my above-ground pool. Pool is nice and warm and has extended the season. I live in Cowes, Victoria.

The Vertex kit was reasonably easy to install for a competent handyman. The plumbing and wiring instructions were clear to follow. We now have a hot spa from October to April without turning the electric heater on (except in very cold or cloudy spells). This is in Melbourne and has had no problems in 4 years.

After having rubberised strip pool heating for many years and the issues that come with that, I decided to install OKU panels as an experiment. They were very simple to install, well-designed, almost bulletproof, and extremely effective even in Canberra. My only regret was that I should have done it years ago.

Product has heated the pool without issue for 8 years. Highly recommend this company, and I would use them again.

We purchased these panels in August 2015. They were easy to install, well-constructed, and very durable. No problems with them over time, and they still look as good as new. All pipework and connections are solid, and I would recommend them to anyone. A fantastic product.

I’ve had my OKU pool heating system for 2 seasons now, and the "bang for buck" with this system is incredible. I’m a fairly handy person and installed the whole system myself over a weekend. The quality of everything in the kit is outstanding. I’d researched the hell out of all available solar heating systems and IMHO the kits that EcoOnline supply would have to be the best on the market.

Easy to install, excellent value. Came with everything you could possibly need to complete the installation. This system is super efficient and is not unsightly on the roof at all. Can't speak highly enough of the product or the company and the service they supply.

Well-written, easy-to-follow manual. Customer support line was an Aussie technician who knew his stuff. Hooked it all up, not one leak, and very happy with the value of the deal! Thanks, guys.

Very good quality product at a good price. Super fast delivery with no problems. All the info we needed was supplied, and if there was a problem, the support was immediate.

I've purchased OKU solar panels from EcoOnline. I've been super impressed with the German quality of the product (very reasonably priced) and the detailed installation guide. Greg has been absolutely amazing in answering many of my emails and guiding me through the process. Highly recommended!

18 OKU panel retrofit, pool went from 20°C to 29°C in three days.

I found the system easy to install, and it worked straight away. We had a hot spa within a couple of days, even though I installed it in Autumn. Even in winter, the spa was around 32+ degrees if we had 2 or 3 days of full sunshine. Most impressed. I have no hesitation in recommending EcoOnline to others. Bonus has been the huge reduction in power bills.

The system that I purchased from EcoOnline is now up and running and has performed well from the beginning. I appreciated the technical advice from EcoOnline at the time I was working out what to purchase. The collector panels are physically strong. I was pleasantly surprised that the installation manual said that I could walk on them during installation.

I purchased a solar system for my spa. During the summer, it has worked very well in keeping my spa hot. Hopefully, it also works as well during the winter months.

The total cost was very reasonable. The staff were good and helpful. Very happy that I dealt with EcoOnline.

Very good communications, very fast delivery. Very efficient heating system. Can’t recommend it enough.

For our pool, all installation documentation was easy to follow and very comprehensive. I compared prices to other suppliers and EcoOnline beat them all with no compromise on quality. Highly recommend, especially for the DIY'er.

We purchased the Pool Master Pro system. Greg answers all my queries and is very helpful.

I have received over the past 8 years! Greg is such a great person at EcoOnline. I would recommend EcoOnline products to everyone that is looking for quality, Greg's honesty, and a level of service that is by far one of the very best in Australia! Thank you!

After-sales support is where so many online stores fail, but EcoOnline has been excellent. Very happy with the system and the instructions too.
