Adding a heat pump

Heat pumps are added to a design within the Plan task.

While on a design option, drag and drop a Pump from the left-hand sidebar to place a heat pump in the plan. After placing the heat pump, you can select the model. Choose from the recommendations or scroll through the sections on the left, sorted by brand and type (monoblock and split).

When a heat pump is selected, on the right you will see specs, and Midsummer stock levels and pricing. If your account is connected to Midsummer, you will also see your specific pricing.
