Solar Water Heating negative results for energy

Hi Nick,
yes these results seem more reasonable.

Appreciate,

Hi Nick,

is there any estimated date for the patch release?

Ioannis

Hi Ioannis,

We pushed the update to later this week or early next week. Sorry for the delay, I will post the exact date once it's known, likely Friday or Monday.

Thanks,
Nick

Hello all,

Others have asked what the expected behavior should be when modifying FRUL, noticing that increasing FRUL caused an increase in energy saved when they would expect a decrease.

This is related to the bug previously described for multiple collectors. The value for FRUL input into SAM is used in equations affected by the bug, such that unexpected behavior occurs. With the correction, SAM produces reduced energy savings as FRUL is increased as expected. The correction will be available in the pending re-release of SAM version 6.30.15.

Thanks,
Nick DiOrio

Dear Nick,
any update on the release date of the upcoming patch?

Hi Ioannis,

We're working on a few other updates for the patch, and hope to release it by this Friday at the latest.

Best regards,
Paul.
