[EnergyPlus_Support] Problem with pumps

[Lyuben Barosow <lbarosow@xxxxxxxxx>]

Hello Everyone,

I am trying to model a Radiator Heating system and I have a problem with the pumps. I've attached a scheme for more clearance. The water from the boiler is transported through a circulation pump (pump 1 on the scheme) and then distributed to four consumers, each on a separate branch. Each of these branches also has a circulation pump (pumps 2, 3, 4 and 5). When I try to model this exact situation in E+, the following error is being generated;

** An active component should not be present in the first branch in conjunction with branch pumps

** Current version does not support Loop pumps and branch pumps together

How should I proceed in this case? Should I remove the pumps 2, 3, 4 and 5 which are on the branches, or is it better to remove pump 1 and leave the rest? Or is there some other way to solve this and how would it reflect on the energy consumption?

Thank you!

Lyuben
