Hi bro @zheilwane. Wanted to ask what piping are the best for home? Ppr or Ss? If ss got any particular brand or spec to look out for?

I had purchased aquasolar. Thought there would be some form of temperature control with the system but the aquasolar guy only said there is manual switch turn on n off the electric backup heater only. And recommended not to leave it on at all times.
Also I have a water pump after my water tank for whole house cold water system. Does the hot water coming from solar outlet need to use pump also?

What about the solar inlet where is the best tapping point ? From main or after roof tank pump?
