Does it matter if you let Silus live?i always do.

i have a save right before the ritual and i've tried it thrice,they NEVER respawn.

tips?

The responded for me twice. Once two appeared outside of shrine entrance when I arrived and the second time none appeared outside, but two were in the shrine. Havent seen any since then and its been about 30-40 in game days. The loot (ingots, gold, etc.) respawned but not the Daedra.

If you are just looking for Daedric hearts, there are other ways to obtain them.

Not even the loot respawns for me.

I'm after mainly the loot,the hearts and destruction xp is nice too,i'm trying to get a lot of cash because i've almost reached my self imposed level cap and i still need about 30 enchanting lvls.

If you let Silus live, you cannot acquire Mehrune's Razor.
