baseboard heating

egrosarioegrosario Posts: 2Member
I want to install a loop of my gas steam boiler.
I can I get away with a gravity loop instead of adding a circulation pump?
Is going to be two baseboards with the run being less than 25 ft.

    Piping and wiring as a separate hydro zone is the way to go.

    Thank you HVACNUT,
    I am going to pipe a separate loop with a bypass..
    What I am trying to do is go with a passive hot water loop.
    This is typically use for domestic. I was wondering if I can use this system along with a gravity loop in place of a circulating pump.

    Problem is... with very little elevation difference, you'll get almost no flow at all. Use a pump.

    It takes elevation differential and also temperature differential.
    I have the gravity loop on my DHW and it achieves only a small trickle flow, good for DHW but not enough to heat BB. IMO

    You could pipe is as you talked and if it does not work just add a pump later.

    You could also pipe the wet returns through the baseboard and this could act as you’re detailing.

    Why exactly "off topic" ?

    Probably a fat thumb. Hate to thing off how many times I have accidentally clicked the wrong tab
