Re: [TRNSYS-users] Solar thermal panel and auxiliary heating

[dias.marcos@portugalmail.pt]

Dear Arnaud,

I'm not very specialist on TRNSYS, but i will give you my opinion:

1) Solar energy is not the best energy to use in space heating. This  
is easy to understand, because in the winter you need big energy  
amounts to heat a house for example, and the solar radiation is in  
it's lower values... so, this is not efficient to use solar energy int  
the winter.

2) Forgetting the previous issue, maybe you will need to put between  
both items: tank and building any equipment. For example a heating  
fan. In my idea, you can't put water directly in a building, you must  
have some equipment that uses that hot water to transfer it's energy  
to the bulding.

I don't have my computer with me, so i'm just giving a opinion without  
trying it.

Good luck!
