Solar overheating can occur within solar water heating systems for a number of reasons but it's basically because the heated water being produced is far greater than the actual demand for heated water by users (supply is greater than demand).
This can be because:
If your system is oversized or not, you can safely dump any excess heat to a radiator or heat exchanger within the house to provide space heating. Heat can also be dumped into a swimming pool if you have one.
Solar heating with a dran-back system is another way of preventing overheating. A drain-back is a system that drains water from the collectors when the pump is not operating, i.e, when the storage temperature has been achieved the thermostat will shut the pump down. When the pump is switched off, the water will drain down from the collectors into a receiver tank thereby preventing overheating.

Hi, My name is Shannon and I'm one of home-heating-systems-and-solutions.com readers. I'd like to thank you for the excellent information I've found on home-heating-systems-and-solutions.com, it's one of my favorite readings on the net. Warmest Regards Shannon United States
Thanks for the advice for removing an air lock from an indirect system. Had to change an inlet on my cistern. First time I have tried any home plumbing. After draining the cold tank system air locked when I refilled the tank. Garden hose and mains pressure up the tap sorted my problems. Would not have known what to do without the advice on the site. Many thanks Sean United Kingdom.
An excellent site. I have found it very usefull. I am currently in the design phase of a new house and have be pondering which heat system to use. From your site I have been able to choose the right system. Ross New Zealand
