OK-Living Solar heating Black 70 x 600 cm,

Good purchase decision, we would buy again and again!

We have installed the pool heater on a garden shed roof. The normal filter pump could not manage the height of 2.50 m. We therefore connected a submersible pump. Therefore, we connected a submersible pump. The installation was very easy. A warming was noticed. Therefore, there is a purchase recommendation and also the full stars.

I have connected the two mats in parallel, not in series as specified by the manufacturer. This creates less pressure and the water can flow through better.

Super solar collector. What I have not found in the reviews so far is that you absolutely need a third hose or, if necessary, a bypass solution. And ... I didn't have to seal any of the connections! I have connected the system, secured it with clamps, and nothing is dripping! Heating capacity at full radiation so far 5 degrees in 4 hours with a pool volume of 2300 litres and a pump capacity of 1300l/hour. A super cheap alternative if you can live with the logical, weather-related adjustments. I can only recommend it

The pool heater is intended to take some of the load off the electric heater in my whirlpool (~800L). I installed the pool heater on a concrete flat roof. I last measured the temperature on the surface of the roof when the sun was shining and it was 51 degrees. The air temperature was about 28 degrees at that time. During the installation of the pump, the pool heater was already filled with water. After a few minutes, I switched the pump on again and hot water arrived at the other end. During normal flow, the water was heated (subjective estimate given my circumstances) 2-3 degrees as it passed through. +: Product is easy to install. Connections are plugged into the heater and secured by twisting on a locking lug. Sealing rings are also included. I was particularly thrilled that hose clamps were included. -: The workmanship of the product looks cheap in some places (see pictures). Doesn't limit the function, but still not nice. It is also a pity that the package does not include any brackets to fix the heater to the ground, so you have to buy them separately. During the last storm, I was able to pick up the pool heater from the front garden. The endurance test will show how well the plastic copes with the sun on the roof.

if there is enough space, it is a great solution.

Apart from the fact that the instructions are only in English, this is a great article. Heats up my pool (13 m³) super. Installation takes about 1 hour and is super easy. I wanted to get 2 mats at first, but even with one I reach 31°C.

So the product fits 100% anyway I lost the installation plan and immediately received a PDF after contacting them on Sunday! When customers complain about leaks in the connections, you have to say that the connection point fits, but pool hoses have tolerances and it's not the manufacturer's fault. Teflon tape and you can fix it

Works great. It is mounted on the garage roof and provides a lot of heat when the sun is shining.
