But replacing between different systems does seem to be a nightmare.&lt;p&gt;It&amp;#x27;s interesting that Americans are retrofitting them into HVAC systems, while in the UK we&amp;#x27;re trying to retrofit into natgas&amp;#x2F;water based systems, and seemingly the Scandinavians have gone for .. I&amp;#x27;m not sure but it seems cheaper?&lt;p&gt;I upgraded to a &amp;quot;hybrid&amp;quot; system because it was the least cost &amp;#x2F; minimal change, so I continue to have natgas hot water which can optionally heat the radiators if the control unit deems it economic (no, it doesn&amp;#x27;t have dynamic pricing). And that was still £15,000 even though it could reuse all the existing radiators. Apparently having 8mm &amp;quot;microbore&amp;quot; copper plumbing is a problem for &amp;quot;low temperature&amp;quot; heat pump systems, because they rely on higher throughput.&lt;p&gt;At the end of winter I&amp;#x27;ll write-up my bills and evaluate the experience.</text></comment>
