Domestic hot water storage tank

I bought their solar heat pump system last month only and so far it's running good. It's only a month and I will update if there's any issue comes.

I got a lot of reair dones and lot of issues keep happening for my previous solar heater like the water would evaporate constantly until I finally decided to replace it with Sunmax heat pumps and so far no such issues are happening.

I live in a place where the majority of the year the climate is cold. So hot water is essential for us and sunmax is the only system that provides good hot water and the others we used were weak in terms of water temperature.
