    Hi,

    I just move into a new house and it has a Eternal gas (propane) tankless water heater.

    I've noticed that it has a overflow PVC pipe running to the outside of the house and it seems to always be dripping. Is this normal?

    Also, would I be better off to switch it out for an electric one?

    Thanks! Kevin

    The Eternal tankless is a high efficency model, and what you are seeing when it is running is condensation. That's normal.
    When a heater squeezes all the heat it can, a byproduct in the exhaust is water. That water needs to be drained off. You will notice that the exhaust is plastic pipe. That's to prevent rust through.

    If you have a floor drain, you can run the condensation there.

    Thanks Terry!

    I your opinion, would you stick with this Eternal propane tankless or switch to an electric model?

    Thanks again. Kevin
