I came across this link by accident and would like if I may ask what experience either of you "solar experts" have had with pressurized systems ? 

Are you using scare tactics to try and put people off a product that you do not sell or is it you do not understand how they work ?

We have sold/installed over 300 of these what you make sound like "time bombs" over the last seven years and we have never had one leave a roof to go orbiting the earth under its own propulsion. YET!

There have been over 3 million pressurized units installed in the  med area over the last 10 years, over 100,000 in Israel alone. Exactly how many tanks do you know have "exploded" or indeed "imploded" due to a faulty valve ?

I know of over 15 people who now have one of our fully pressurized units as a direct replacement to these cheap gravity feed or pre heat coil in tank systems you talk of.They are fine for the poor under developed third world countries that they were designed for. Please be honest with your audience you are pushing them not from some great safety concern or for your clients best interest. But purely as they are very very cheap to buy and you make great profit margins when you sell them.

I look forward to your responses.

Kind regards.

Keith.
