@ July 10, 2013 10:44 AM in Condensing combo boilerHi fellow contractors on the wall! I'm converting my cabin from electric basebrd to hot water basebrd and radiant. I haven't used anyone's combination boiler/ water heater wall hung unit. Looking for feedback pros and cons. 1200 sq ft cabin, 2 baths 4 people, nat. gas
@ December 9, 2012 10:35 AM in Creeping pressure on boilerThanks fellas! I've never encountered this problem in all the years. Can't believe I didn't think of that. Great site to get other expert opinions. I appreciate the feedback so promptly.
@ December 7, 2012 1:16 PM in Creeping pressure on boilerHi fellow contractors! I've been at his p&h business over 30 yrs. Got a Vaillant 80% eff. 25yr. old boiler driving me crazy. New #30 amtrol exp. tank and new pressure reducing valve still get pressure creeping up to relief valve leakage. Boiler sounds a bit limed up when it gets to temp. about 170-180. Exp. tank hooked to bottom of air scoop and has clear passage thru. I even put an additional #30 tank on return side off boiler drain just to try SOMETHING. Worked for 2 wks. got a call again relief leaking. House is only 1600sqft. ranch. Also has 40 gal indirect fired water heater. What am I missing here? Is it the liming up? Even with 2 tanks? I appreciate anyones input.
@ February 2, 2011 1:09 PM in black streaks above baseboardsI have a client w/ black streaks above all the baseboard radiation in house. Its a 3yr. old Weil McLain CGA boiler natural gas. Boiler is clean as can be w/ plenty of fresh air in room. Older home which cannot be that air tight. Told her to clean heating elements as good as possible. BB has min. 1" clearance from floor. She swears streaking is has not been there for long. Any other suggestions out there?
@ April 20, 2008 9:05 PM in powerless radiant systemsHas anyone ever been involed w/ radiant system w/ no power?Heats w/ wood only. Thermal siphon???? I realize its not too safe, but we have an unusual situation.
@ March 1, 2007 10:12 PM in radiant heat installed on top of basement floorI've done plenty of radiant work thru the years, but never on top of an existing basemt. floor.I'm looking for the most cost effective yet reliable method. Basemt. approx. 1400sq ft. I'm looking for tested true ideas. Thanks
@ January 22, 2007 6:59 PM in monoflo system integrated w/ cicuit loopsystemI am doing a addition on a home that has monoflo through out house. I've been doing hydronics for years and really never ran into this scenario. I would like to make the addition a circuit loop zone, with the rest of the being left as is, monoflo. There is a seperate zone valve for this area already. There will be approx. 55' of baseboard installed w/ total circuit lghth of 90' 0n 3/4" cop. tube. Seems doable to me or am I looking for problems?
@ November 10, 2006 8:24 PM in My First KnightI am currently installing a new Weil-Mclain boiler w/ Amtrol WH-7Z BOILERMATE. Existing zone valves are 3-wire White-Rodgers #1311. Boilermate has only 2 stat wires for use on a 2 or 3 wire zone valve. Can I successfully integrate 2 and 3 wire zone motors w/out a seperate isolation 24v relay? I am getting conflicting answers from Weil-Mclain and Amtrol. I'd much rather not add more contols unless necessary. Thanks! I love this website!
