    Default hot water from hoods

    question for hood guys- how much water do you get from a pre-heater hood vs. non-pre-heater hood.

    also- can you get water from a non- tight (ie. oversized hood) hood?

    I'm looking for hot water, and if I could get a hood out of it, that would be great also...

    thanks -

    You want a preheater if you want hot water. They generate a lot of water. You won't get a lot of water off of just a hood. You'll get a steady stream of 200+ degree water from the catch pan under a preheater.

    You will only get hot water by having a pre heater. A hood alone without a preheater will not do much unless it is cold on the outside. Once a hood warms up and there is no temperature differential you will get no condensation. When you have a preheater with 212 steam and 40 degree sap there is a big differential so it gives off alot of hot condensation
    Also the amount of condensate will vary depending on the size of the preheater and how hard you are pushing the evaporator

    Before we added the preheater to our hood we would get some water. Not much and it wasn't vary hot! Once we installed the preheater, we get more hot water than we can posible use and so hot that you can't put your hand in it! Jim L.

    About 7 to 8 gallons per hour of hot water off our 3 x 5 rear pan with copper parallel flow preheater, with very little coming off the hood.

    Wow! 55 gallons off of a steam away I hadn't considered that much condensate.
