So, I have a customer who has a house he is trying to sell but is not living in and he would like me to switch off the water main and drain everything down as he is worried about something leaking whilst he's not there, system is standard back boiler and cylinder but also has two solar panels piped into the cylinder. I know nothing about solar.
Questions
Is it best not to drain the cylinder ( solar or not ) as this will increase risk of corrosion ? Just empty the tanks?
If I do drain everything except solar will the solar be alright ?! or will it pop on a sunny day as there's nowhere for it to dump its heat or do the ex vessels account for that?
If I drain solar what do fill it back up with and how?
