building a paralel pre heater and hood

[bart61]

I'm building a paralell preheater and hood for my 2 by 6 evap. Is there a preference to having a peeked hood or a some what more rounded to a small flat space on top? I've seen pictures both ways on maple traders. Does condensation run off one of them better than the other.

made it through my first post.

Congratulations! Welcome aboard. I would say the less "flat roof" you have the better. Condensation will run down a sloped surface, but the droplets that form on the flat top of a hood just drop back into the sap. Although the preheater drip tray may catch a lot of them. Depends how big that ends up being. Hope this helps.

Once the hood gets up to operating temp there will not be much condensation any way, on the hood. Mostly it will be on the preheater.

I am using the drip channels under the copper tubing method for removing the condensation that forms on the tubes so there wont be a tray under it to catch any residual drops. I'm also puttig a small round catch pan under the stack to catch it's condensation or do you think thats just overkill. Thanks everybody for your in put.

I think the catch pan under the stack is a good idea since your your not having a tray. You want to 'catch' all that you can- why boil the water twice!
