			<![CDATA[The British Standards Institute has published a draft standard for domestic solar hot water systems. It appears to assume a pressurised system with heat exchanger inside a domestic hot water tank & to exclude all other approaches. This is a strange approach given the immaturity of the market in the UK & the benefits of alternative approaches. For example, it would seem to exclude drainback systems where a thermal store also acts as the drainback reservoir. <br /><br />Hopefully this draft standard will encourage some informed debate & be re-written in a way that encourages innovation in both component & system design. If it goes ahead unchallenged, it will probably have a negative effect on the development of efficient, low cost, integrated systems for new build or retrofit.<br /><br />If you have any views then you might like to comment on the current draft: <br /><br /><a href="http://drafts.bsigroup.com/" target="_self" rel="nofollow">http://drafts.bsigroup.com/</a><br /><br />Search for BS5918 & you should find "Draft BS 5918 Solar heating systems for domestic hot water â€“ Code of practice".<br /><br />You need to register to leave comments, but registration is free & quick. <br /><br />David]]>

			<![CDATA[You're right. I was driven to comment after only reading the draft scope which is viewable without registering, but you need to register to review the document itself. Its relatively painless & requires the minimum of information.<br /><br />David]]>
