Customer declaration:
Since 2014, the ELWA has been in operation, paired with a 2.25 kWp PV system. The installation took place in a 1,000-litre buffer storage with a fresh water station. While we usually do not utilize the optional hot water backup with mains power, this feature proved to be useful during a renovation phase in unfavourable weather conditions.
What initially appealed to me about the ELWA was the simple installation. Now, I appreciate that this solution is not only easy to install but also entirely maintenance-free. I have also acquired the USB interface from my-PV, allowing me to retrieve data and monitor both the PV thermal yield as well as the temperature profile.
On days with fluctuating weather conditions, when I inquire about my neighbour’s thermal solar system and whether it has delivered any results, he often denies it. In the meantime, my ELWA consistently generates 4 kWh of heat, even on overcast weather. It's truly a brilliant solution!
