I have a friend who has unseated pool, thinking of several big bits of black poly floating on broom poles weighted down to float vertically and cover pool at night with bubble wrap]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281769#Comment_281769 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281769#Comment_281769 Sun, 28 Jun 2020 11:10:42 +0100 Ed Davies
The question then is would that be true of the diversion to the pool - e.g., what happens if the three-way valve or thermostats become stuck in any plausible state and if the safety relies on redundancy will it be obvious if that redundancy is lost (e.g., if there are two thermostats and one sticks will there be an indication of that).

How do you transfer the heat to the pool water? If it is, as I assume from the size, a swimming pool then presumably it has chlorine or salt or something in it so I'd guess there's a heat exchanger somewhere as that's not the sort of water you want going through most solar thermal panels. Is there a pump on the pool water circuit for that? What if it fails?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281771#Comment_281771 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281771#Comment_281771 Sun, 28 Jun 2020 11:57:23 +0100 CWatters http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281772#Comment_281772 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281772#Comment_281772 Sun, 28 Jun 2020 12:31:23 +0100 Ed Davies http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281774#Comment_281774 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281774#Comment_281774 Sun, 28 Jun 2020 16:33:36 +0100 WillInAberdeen
Alternatives are allowed if they give equivalent protection, for example a solid fuel burner can't have a thermal cutout so it needs to have gravity dump radiator/s instead.

Unvented systems are supposed to be installed by people who can demonstrate competence, such as with a registration scheme, they can then self-certify the installation without it needing to be inspected.

This is all technically a requirement for hot water storage systems, but seems to be widely applied, eg to central heating systems.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281775#Comment_281775 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16625&Focus=281775#Comment_281775 Sun, 28 Jun 2020 16:39:53 +0100 owlman You may have a combined pressure/temperature relief valve which should be attached to a tundish, with visible discharge as your safety, if your system is pressurised.]]>
