&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[https://www.leti.london/retrofit LETI Climate emergency retrofit guide, How existing homes can be adapted to meet UK climate targets], published by LETI in October 2021, defines primary pipework: The pipework between the hot water source (e.g. heat pump) and the hot water tank. This pipework will tend to be of a large diameter and will be used whenever the tank needs to be brought back up to temperature.’&lt;br /&gt;
