Sacie: Tell him to try adding automatic air eliminater valves at the heater's inlet and outlet. That's what I had to do. Get a good one like Spirovent; not sold in my nearest Home Depot.<BR>

<BLOCKQUOTE style="BORDER-LEFT: #ccc 1px solid; PADDING-LEFT: 1ex" class=ecxgmail_quote>Our son in Seattle,lives in a house with a 2007 installed radiant floor heat on the main floor, baseboard heat in the basement and 2nd floor. Three zones. The water heated for the system is powered with a Takagi tankless. Open system. It is not working right. Has apparently required a bleeding numerous times within the week period after he moved in. Plumber called initially to show him how to bleed. This guy told him set the Takagi for 156+ degrees----'only way it'll heat up those floors" or something like that. Pex tubing.<BR><BR>I believe his system has a small holding tank connected with it.<BR><BR>This is Seattle. ANy suggestions from this group about what goes here? I've googled anything I can think of connected radiant, tankless and bleeding/air, but find nothing remotely useful. Lots of advice though. Comments about the high heat admonition too. Never heard of this.<BR><BR>We have a radiant floor system ourselves, but heated with a DHW heater.
