    Default Gravity Fed Hot Water

    Hello Everyone,

    Not sure if this is the best place to post this or not but here goes!

    Basically what I am looking to do is get hot water to fixtures quicker. House is a Tri-level with a basement. My hot water system branches off into two different directions so will eventually need two loops. For now Im focusing on the loop for the main level. I have a 50 Gal. Marathon water heater in my basement and Im going to try the gravity fed route first and add a pump of some sort later if it doesnt work out. I also have a FHP Geo unit with a DSH. Below is a picture of my existing setup minus the purple return line w/check valve and the check valve on the DSH return line. My existing expansion tank is 2 gal. and total loop run will be approx. 55 ft. From what Ive read I need to use a swing style check valve on the loop and drill a small hole in it for convection.

    Im basically looking for any input, recommendations, etc. Any and all help would be greatly appreciated.

    Will this system work like this? Should I make any changes? All pipe is 3/4 copper. Should I go with a bigger expansion tank or will the 2 Gal. be sufficient?

    Thanks,
    Scott S.

    That should work very well. When adding the 2nd loop install a valve on each loop for balancing.
