will be available in an update to the TESS HVAC library that
we're hoping to release at the beginning of october. If you need
the models right away then they are available as individual

<p class="MsoNormal"><span lang="EN-GB">as part of my research I
would like to model a building with domestic hot water and

<p class="MsoNormal"><span lang="EN-GB">As I would like to model
the state of the art I would like to use a heat pump with
variable speed compressor. Is there a variable speed heat
pump model or any known workaround with the current existing
models?

I have the HVAC Tess-Library, but can only find 1- or
2-stage heat pump models.<o:p></o:p></span></p>
