But what many do not consider: these systems have an Achilles&#8217; heel. <strong>Sludge.<\/strong><\/p>\n<p>More precisely: magnetite, <a href=\"https:\/\/uws-technologie.de\/en\/what-influences-corrosion-in-heating-circuits\/\">corrosion particles<\/a>, and deposits that accumulate unnoticed in the system over the years.

The heat generator keeps ramping up without the output arriving \u2013 <strong>a prime example of inefficient operation<\/strong>.<\/p>\n<p>The reason: Over the years, a sometimes tough layer of magnetite, rust, and lime builds up in the narrow pipe cross-sections.
