@ March 18, 2013 5:18 PM in Adding a secondary pump to my radiant heating systemFirst, I don't think the second pump idea will work.
What pump do you have now? What are the sizes of all the piping?
What water temp do you have running thru the radiant?
Where are the radiator loops on the diagram, and what temp are they running at.
How many btu's do you need for each loop.
Lets evaluate the design first to make sure it can do what you need it to do as far as flow, btus, right circulator, etc.
@ March 16, 2013 6:19 PM in weird monoflo?Between the 2 reducing tees you want to put 2 more tees?
I don't think that will work. You may not get flow thru the branch the the original tees were serving. Or you may need a way to throttle both the original branch and the new branch, or you may not get the propr flow thru one or both.
If I misunderstand please show a sketch
@ March 16, 2013 12:13 PM in weird monoflo?Just looks like pre-monoflow fittings, smaller diameter pipe between the reducers forces some of the flow into the loop. I would guess you could do it the same way, but I would pipe in a globe valve in the main run in case you need to throttle, to get a little more flow into the radiator.
What was the return temp by the time you get back to the boiler?

@ March 1, 2013 8:03 PM in weil mclain oil boiler help pleaseIt's hard to diagnose your problem with the info provided. Even worse, was someone started changing parts without figuring out the problem.
I have a number of QB burners in my customer base (9 or 10 I think), some work great, some ok, some not so ok. Yes parts are hard to come by, but still available. If you call Weil McClain, they will direct you to the right place.
That being said, I would switch to another oil company..."this burner is junk" is a pretty poor, unprofessional diagnosis. Could be as simple as the head adjustment. If they checked everything properly, they should've found the problem.
Sure a new burner might help, and might be what you need to do in the future, but why give them that business.
@ February 24, 2013 4:58 PM in Can you sufficiently heat up a 60 gallon superstore with high limit at 160 degrees?easily with a Tekmar boiler control. He would get outdoor reset, and when he gets a DHW call, the boiler temp will bump up to whatever temp you pick. Keep in mind you're not bringing the water temp from ice cold to 160. When I get a DHW call, my control resets the boiler target temp for 170, and usually doesnt even fire til I'm done my shower (TMI?), then only fires about 10 minutes to satisfy the indirect aquastat (not in priority mode).
@ February 24, 2013 4:47 PM in No domestic hot water from oil fired on demand boilerhttps://customer.honeywell.com/resources/Techlit/TechLitDocuments/69-0000s/69-1720EFS.pdf
Start out with your low limit on 160, hi on 190, diff at 10 degrees. If this doesnt help, time to bring in a pro. Could be limed up coil or bad thermostatic mixing valve.
@ February 21, 2013 1:55 PM in Radiant heat in a bathroomThere are some panel radiators, & hydronic towel bars that might do the trick...
@ February 21, 2013 1:52 PM in winterizeTo me, 43 is cutting it close. Doesnt give you much leeway if the system has a problem. If it were me, I would make sure there is some freeze protection to warn you if the heater shuts off--alarm contacts on the primary control or thermostat. Also, you should have a low water cut-off also...just in case.
@ February 20, 2013 9:55 AM in Tekmar Controls with Indoor ResetI have yet to use this Tekmar Boiler Control, so I couldnt comment. But if you email Tekmar support and ask them all your questions. They wont just "yes" all your answers, and tell you it will work great, they will take the time to fully understand whats going on, and make recommendations.
@ February 20, 2013 9:49 AM in One Zone Stopped Working (troubleshooting ideas or call a plumber?)It's probably something on the wiring/control side. Could be a bad zone valve, or some other control. Without knowing what other components are on your boiler, your best bet would be to call a qualified oil tech to come out and do the basic troubleshooting.
Regarding the thermostat, if the room temperature is below the set point temp, and the thermostat is not indicating a call for heat, then you can start at the thermostat.
I have a customer with a similiar "energy saver" thermostat from the utility company, that was having a problem. After talking to the utility company, they told me, the customer should call the utility company, they will come out for free and check the thermostat. If it is bad they will replace, if not bad, tell the customer to call their hvac company to repair the system
@ February 18, 2013 4:40 PM in Spare PartsDo you know anyone in the business? Cause pretty much everyone has one, or at least a 3 speed, on their truck.
@ February 15, 2013 3:36 PM in Radiant Heat QuestionsInsulate the pad. Otherwise it just wont perform well. I would match the concrete pads in elevation, insulate above the pad, and frame over that. A better choice, if this makes the floor too high, may be to do a radiant ceiling, but still insulate over the pad.

Edit. Appears you figured it out in your other posts
@ February 12, 2013 4:32 PM in Direct Vent 80% boilerWhat fuels are the boiler and the hot water heater burning?
Most likely, your chimney is failing, and even though you probably could line it, I wouldnt without a certified inspection with a recording camera. The problems you see in the attic, peeling, etc are a sure sign the mortar is long gone, with the chimney to eventually follow.
Go with the above recommendations and use the sidewall venter.
@ February 11, 2013 10:26 PM in Beckett cf500 burner smith a19 series boilerDraft? Excess air? Then I would check the delay valve & pump cut off, transformer, etc
@ February 11, 2013 10:15 PM in Beckett burner leaksCheck this with a plugged nozzle in the nozzle assembly, outside the burner, attached to the pump (watch out with the transformer opened)
@ February 10, 2013 5:20 PM in bad boiler installation?I feel bad for you. How do you get the aquastat cover off...or even the aquastat? And forget about removing the burner or swinging the boiler door for a cleaning. The only long term correct approach is either a different boiler that can fit in the space, or that boiler on a different place
@ February 6, 2013 9:44 PM in Slant/Fin Hydronic Explorer 2.0 Help NeededOn geometry. I have come across this too. I just break the odd shape rooms into rectangles and triangles, and do the math that way.
Do you have a specific problem your trying to solve?
@ January 20, 2013 5:53 PM in What controls this:Did you happen to see these 2 PDFs?
The Tekmar should be doing almost everything, especially the mixing valve. There's a tedious checkout you can do on the Tekmar ( it's in the manual) which may help.
Maybe the Tekmar just isn't set up correctly by the original installer, and the sensors are in the wrong spot. For multiple zones there should be another zone control wired properly to the Tekmar
One thing I noticed with the Tekmar, when you have boiler protection set, something odd (to me) happens with the mixing stations. To 'protect' the boiler it will close 4 way, or stops injection mixing--which its suppose to do. But it seems to, I can't explain it, come out of this in a way that doesn't seem logical, & causes performance problems. Maybe someone else experienced this and can explain it better.
Any chance you can scroll thru the Tekmar menu and post the settings?
