Look at an example file for the solar collector. SolarCollectorFlatPlateWater.idf with .rvi
Then use the template to model the baseboard system.
HVACTemplate:Thermostat and HVACTemplate:Zone:Unitary with a hot water baseboard heater in the zone. This should be expended to a zone loop with a boiler tank. Use the code lines in the expIDF for the HW loop for pasting into the final IDF.
The solar collecter to the storage tank would heat the water in the storage tank. Use this tank as the interface between the two loops.
I.e. cut the solar collector loop at the storage tank and connet the use side of the tank as the supply to your zone baseboar branches.
No template model should be in the final IDF. All the unused branches and schedules for the domestic HW use should be removed.

Subject: [EnergyPlus_Support] Water Heat Exchanger
Hello all,
I'd like to create a system with 2 connected water loops :
- a primary loop with solar collectors
- a secondary loop with hot water baseboard heaters
The water temperature into the baseboard heaters must be between 35°C and 40°C so I cannot integrate directly them into the primary loop (which can reach 95°C).
My idea is to connect the 2 water loops with a heat exchanger and control the temperature varying water mass flow rate.
But I cannot find the correct model of water heat exchanger in EnergyPlus library.
The only one which could match is the "HeatExchangerPlate" but it is dedicated to condenser loops and I cannot use it in my case.
Following issue is how to define the secondary water loop, as there is no direct heat plant into it ? It seems to be required into a water loop.
If someone has worked on similar configuration and can help me, it would be great.
Thanks you in advance.
Regards
Fabien
