the tank was solar/electric combo.
I don't like the thought about relief inside my bedroom. prefer it on the roof.
Isn't an open vent the best pressure relief?

Thoughts..

The tank.
In the midel an electric heater with thermostat 50-90 cellsius.

A sketch of the collector.
It is only metal pipes

Hi!
Thank you very very much!!!
Yes I'm in palstine. (33-34 parallel)
I'm deside to make it drain back
Am I realy need a controler or anything? I planed to just operate it manualy. 10 dolars are not a problem but I want to keep it simple and I don't want the controller will cancel my plans to oprate the system at sumer nights too.
If it is draiback, do I need the over pressure/temprature/vacum stuff?
The pipes conectors are seeled with natural flux. It's better then teflon because it get bigger when it get wet.
the bottom of the collector is 2.8M above the bottom of the tank.

Im dont asking abaut electric solar panel at all

" good heat flow/rise to the upstairs."
Its not sound good at all

And the pumps' papers

Here is the pump I bout

Here is my tank in the corner of my room
