@ October 13, 2012 3:44 PM in water level tubeFurnaces heat air. They don't use water so I don't think you have one.
Hot water boilers heat water which is usually distributed by circulators (pumps). Some of the older ones have the gauge you describe, they are usually mounted on the expansion tank.
It sounds like you have a steam boiler. The gauge would be mounted on the side of the boiler. A picture would be helpful.
@ October 13, 2012 9:22 AM in Open loop system maintenance, flush ?What temp does your system run at? Low temps are bad. If you run your system above 140 you will be better off.
@ October 13, 2012 9:10 AM in Help with delta TAre you measuring delta T at the boiler or coming off the radiant loops?
What type of radiant panels do you have? What model is the knight? Which circulator is on the boiler? How is the alpha set up? How many gpm does it typically show?
Sorry for all the questions. That is a very nice install. The black background makes it look like art.
@ October 12, 2012 9:30 PM in Radiant Pipe Embedded in Concrete Leaking, Heat Lacking in Some AreasI would start out by looking for a local energy auditor. We have a local non-profit auditor that rents them.
@ October 12, 2012 9:05 PM in Radiant Pipe Embedded in Concrete Leaking, Heat Lacking in Some AreasAn IR camera is going to be your first troubleshooting tool. I think you need to figure out how bad it is. If you have one leak it may be worth attacking. Many leaks would have me looking for "Plan B".
@ October 12, 2012 8:59 PM in Pex-Al-Pex expansion noisesGordon,
I am curious about your install. I would like to avoid a similar problem. What type of plates are you using? Do they touch or overlap?
I think a buffer tank and reducing the differential is a good approach. I would ask triangle tube about this. There are many settings that are not in the manual. Maybe they can help you with the differential.
Another option would be to control the boiler with a 3rd party 0-10 vdc.
@ October 12, 2012 8:40 AM in Laas mini-therm llYour pressure valve sounds like it is working fine. What does your pressure gauge say? When the tank is bad there is not place for the expanding hot water to go. It goes out the valve, as it should.
@ October 11, 2012 11:27 PM in Relay continues to clickPut the fuse on the 24v side. You didn't miswire the transformer did you? Some of the ones with extra wires can be confusing. Have you checked the polarity and the output voltage?
The fuse size needs to be smaller than the transformer rating. A 40 VA would work with a 1.5 amp fuse. 1.5 x 24 = 36. Auto parts stores are a good source.
@ October 11, 2012 11:12 PM in I thought I knewI wish you the best of luck with that.
There is a guy on the radiant forum that wants to heat his house with a hot tub. Why not?
@ October 11, 2012 10:58 PM in Hot tub radiant heatThe water will eat the copper.
The water will not be hot enough.
You would be attempting to heat your house with electricity, not very efficient.
@ October 11, 2012 10:46 PM in I thought I knewHenry is very knowledgeable on code north of the border.
To me it comes down to duty rating. Its not that you can't do it. I just won't function optimally and won't last as long.
There are many nice boilers that cost less than Viessman, but more than a water heater. Why are stuck on 2 extremes?
@ October 11, 2012 9:40 PM in Optimal Settings for Munchkin 199 with Vision 1Condensing boilers are most efficient when the return water temps are low. Less than 130 is good. the lower the better. It sound like you have in floor. Is it in concrete?
@ October 11, 2012 9:37 PM in Laas mini-therm llSome Laars boilers of that vintage had electrical gremlins. The one I experienced was having trouble with high and low fire. The cause was the zip ties on the wiring bundles were really tight. This caused interference and control malfunction. Loosening the bundles might be worth a try.
@ October 11, 2012 9:10 AM in piping optionsIt sounds like you have been convinced you should install a domestic water boiler.
I still think it is a bad idea. I would use a proven firetube condensing boiler. A DHW exchanger tank and snow melt with or without an exchanger.
@ October 10, 2012 11:49 PM in converted gravity HWAfter you snake the lines, I would be suspicious of the baseboard conversion. How is it piped? The oldtimers were pretty careful, the convertors, maybe not so.
Check out this on circ sizing http://www.heatinghelp.com/article/343/Circulators/238/Sizing-Circulators-for-Hot-Water-Heating-Systems
@ October 10, 2012 11:36 PM in Relay continues to clickDominic,
Something is shorting out and letting the smoke out of your transformer. I sounds like it is the relay coil. I would suggest installing an in line fuse until you have this under control. You should be able to test the coil with an ohm meter.
@ October 10, 2012 8:16 PM in Boiler died, can HO tackle the install?Could you post a picture of what you are starting with?
I have seen some real DYI nightmares and some that are impressive.
I would start by reading some books. There are a lot of little details that make a good install. Lot's of good books on this site.
@ October 10, 2012 9:38 AM in staple up w plates insulation opitionsI have done quite a few with an air space and never had a problem. I have heard people say it is not needed. I have not had the nerve to try it without. I just don't see the upside.
@ October 10, 2012 9:32 AM in Advice needed on adding antifreeze to boilersI don't believe a drill pump will work.
Once the system is no longer under pressure, you should be able to push glycol through you system using a high head circ pump and a bucket.
You will manually open the valve one at a time to purge the zones.
Be sure to read up on freeze temps vs burst temps. I would lean towards a 30% mix
@ October 9, 2012 9:00 PM in Groundfoss Alpha, home runs and TRVsI don't know how your system is piped.
@ October 9, 2012 1:41 PM in Groundfoss Alpha, home runs and TRVsThat may be the worst I&O manual ever.
Could you post a picture of what you have so far, including the boiler circ and any valves inside the cabinet. It looks like there is a bipass valve installed on the boiler but you can't tell from the manual.
What are you planning on for a buffer tank. Something with 4 ports for hydraulic separation or just a 2 port tank?
@ October 9, 2012 9:46 AM in Groundfoss Alpha, home runs and TRVsThe alpha has a plug factory wired. It is easy to wire it 24/7.
The 260 is set up to run a boiler pump. It may be possible wire the alpha into this.
How are you piped? Do you have a primary boiler circ? Does it run during dhw and heat calls? What type of boiler ? Ar you trying to do domestic priority?
