It being the first time I&amp;#x27;d ever done such a thing (and indeed, the first time I&amp;#x27;d ever really been exposed to hydronic heating at all) I learned everything through reading (mostly the excellent idonrics series at &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.caleffi.com&amp;#x2F;usa&amp;#x2F;en-us&amp;#x2F;technical-magazine&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.caleffi.com&amp;#x2F;usa&amp;#x2F;en-us&amp;#x2F;technical-magazine&lt;/a&gt;). I went &lt;i&gt;really&lt;/i&gt; deep on the reading so while I had&amp;#x2F;have a pretty solid theoretical understanding I was&amp;#x2F;am a complete novice on the craft side of the field.&lt;p&gt;Overall, the practice seems to be very heuristic based, with every installation being a bit different and rules of thumb being the norm. Our system seems to work fairly well in practice, but I&amp;#x27;ve been curious to get a professional&amp;#x27;s opinion on it (the only pro that&amp;#x27;s seen it was the gas guy who did the final hookup, who seemed impressed but didn&amp;#x27;t really offer any specific criticisms).&lt;p&gt;Repo at &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;mtrudel&amp;#x2F;boiler&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;mtrudel&amp;#x2F;boiler&lt;/a&gt;&lt;p&gt;I&amp;#x27;ve since added an elixir based graphing system to it, at&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;mat.geeky.net&amp;#x2F;boiler&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;mat.geeky.net&amp;#x2F;boiler&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Have we forgotten to make heat traps?

I have no idea if it&amp;#x27;s regular practice or not. The only downside I can see is if there was recent hot water, it might take slightly longer to reach the faucet.</text><parent_chain></parent_chain></comment><story><title>Have we forgotten to make heat traps?
