[Equest-users] Wish list - for retrofit analysis

If there was a way to model all the inefficiencies, I would love it.
Another one is leaking steam/hot water valves in summer - maybe the
development team can allow for min flows/settings on the valves for this.

Btw, I think the following is already happening if you have economizer and
the supply temp reset. I always end up with heating increase with
economizer. Have to check if it happens with all modes of control on supply
temp.
