Hello everybody, I would like ta add a heat pump on hvac exhaust air to heat hot water or water heating loop. I didn't find a way of doing so. The zonal air to water heat pump could be a solution, but the air flow rate seems hard linked to the HP operation, while I need a scheduled air flow rate. Any help would be much appreciated. Thanx for all the other useful replies too. Michael

To my understanding, the zonal air-to-water heat pump is the only solution in OpenStudio. You need one for each zone, which does not take into account the real limitations of a single heat pump for a building. The other thing is I have to guarantee a minimal outside air flow rate. As the HP fan is linked to demand side, it would be necessary to add an additional zone ventilation to fill-in. Maybe a sizing object "outside air" or something could manage the total amount of ventilated air through the zone ... This is where I'm stuck. A solution in E+ is also welcome.
