Has anybody had their Alde 3020 water boiler venting off in high temperatures.

Went out today and had left water boiler on...Real-time temp in high 30's...car showed outside temp of 44 after being sat in direct sun for 10 minutes.

Boiler is sited on the nearside of the caravan which was also in direct sun.

Ran some hot water to wash pots and as system was replenished with water from barrel (which was attached to mains on a serviced pitch)we heard a venting off noise which I assume was the boiler venting off pressure due to the introduction of cooler water...is that normal? I cannot see mention of such a thing in the manual

Has anyone experienced the same?
