With some evacuated-tube collectors the heat pipe passes through the end of the glass tube so that the heat transfer medium of the solar cycle can flow directly through it. A heat exchanger is not needed with this type of collector and the collector does not have to be mounted at the minimum angle of inclination.

Flat plate collectors can only heat water up to 170-180°F which means there is very small risk of overheating. Evacuated tubes on the other hand can heat water to well over 250°F. For this reason they are much more likely to overheat than flat plates so you'll need to be very concise with your design.
