Poor quality!

The system was initially installed in 2021 and it worked for a few months before breaking down. Eventually a new display box and brain was installed. This new system lasted for 40 days. It now gives an E8 error code and we were told that another component has to be replaced. Everytime we have to carry the cost of the plumber's callout fee. The savings on electricity is less than the payments to the plumber. Thus, the system is costing more than it saves. If it breaks one more time it will be removed. I will not recommend this system to anyone!
