Heat Dissipator

rajiv123 · 05-15-2009, 05:20 AM

Can anyone answer this question for me, it is probably a simple one but I'm curious to know if it is a problem. I am installing a 30 evacuated tube system in a house in NY with a 120 gallon tank and I was thinking about what happens when the homeowner goes on vacation for a week or two during the summer. Obviously the hot water being generated won't be used so is there a risk of the glycol overheating and boiling? Is there the need for some type of heat dissipation circuit? Or is this not really a concern in this area of the country, with a small system and such a large holding tank?

Thanks in advance.

I don't know about that type of system but usual water heater tanks have a pop off valve in case there is too much heat in the tank which increases the pressure. I would ask the manufacturer.
