Re: [EnergyPlus_Support] Model for Boiler:HotWater

Thank you Julien. I need to simulate the electricity ocnsumption of the Boiler. In the list of output variables the program doesn't show any variables related I just found -Air System Hot Water Energy- that represents the Hot Water Consumption for the system (Joules). It would be this one? I am using E+ V8.1.

Best regards,

Giovani,

There are tons of example files that show you how to set a boiler. Look into the example file folder, there's a spreadsheet that details which example file has what type of system. Typical location is C:\EnergyPlusV8-2-0\ExampleFiles\ExampleFiles.xls

Also, there are HVACTemplate objects to build a boiler plant. HVACTemplate:Plan:Boiler, HVACTemplate:Plant:HotWaterLoop etc... (The Input/Output Reference can help too!)

I suggest you take a look at the example file "HVACTemplate-5ZoneBaseboardHeat.idf" which makes uses of the HVACtemplate objects to build a simple boiler plant.

As far as your other question, I think you may be confused about internal water storage and water flow. Look at your design, or leave it to be autosized for now...

Best,
Julien

Hi everyone, I am performing simulations of an electric boiler. I am using Boiler:HotWater object and my doubt is how to programme the fields Boiler Water Inlet Node Name and Boiler Water Outlet Node Name. Which specific objects should I use in order to operate the boiler (branch, node list, etc)? I didn't find an exemple file correspondent, so maybe an exemple could help me.
Other question is: I have a domestic boiler of 0.3 liters, what should be my Design Water Flow Ratio in m3/s?

Thank you in advance.
