@ February 11, 2011 7:23 AM in can an incorrect system fill blow an expansion tank?now there may have been a defective tank. but filing the system....no.
@ February 10, 2011 5:46 PM in Solia boiler not heating uptwo pumps. One for the system and the other for the boiler. Also I would have the system one contolled by the t-stat and the end switch off that go to the boiler control which in my opinion should be a tankless boiler aquastst. That way the boiler is not prolonged in condensing mode.
@ February 9, 2011 4:10 PM in Solia boiler not heating upthe one circulator? I can't really see that well as to what goes where.
@ February 8, 2011 12:03 PM in Lack of heatHave for a Hot water system? Kind of soulds like a tankless coil... Sounds like it is "Limed up" and is not transfering heat well. Either replace the coil or do an acid wash to get all the crud out. How hard is your water? A long term solution needs to deal w/ that....kpc
@ February 8, 2011 7:17 AM in Need help with sq ft of steam radiatorsai the 1st rad columns or tubes?... how wide is each.?
@ February 7, 2011 10:22 PM in failed diaphram expansion tankpossibility it was on the way out. You probably just put it over the edge. Too bad you have a customer like that.... might be time to tell them to find someone else.
@ February 6, 2011 8:46 AM in Solia boiler not heating upfew pictures to see what you have for piping. Sounds like it is a HIGH mass system and a LOW mass boiler. Not a real perfect match. However it may be fixed w/ a proper piping strategy and some appropriate controls. Running the boiler below 140 is not a good longterm idea.
@ January 30, 2011 8:15 AM in Buderus panel noiseall the air out w/ the system pressure @ 18 psi....? IF the air keeps showeingup I would suspect the air seperator is not working and or your piping is not the best for air removal...what is your system like?
@ January 27, 2011 10:06 PM in Stainless Flue Pipehave for a boiler/ furnace ? Oil or Gas? power vented or chimney vent? kpc
@ January 21, 2011 8:02 AM in 2nd water heater installationis run the water through the coil. Then run the hot water from the coil into the cold of the tank water heater then out the hot water side to your fixtures. Wire the electric heater as if it were all by itself. (make sure it is full before energizing) This will temper the cold water to keep the operating costs down w/ the electric yet the electric will give them a head start.
@ January 20, 2011 5:03 PM in Steam stumper...I will keep at it. The big rad in the living room is a bit better w/ the varivalve.
@ January 19, 2011 11:40 PM in Steam stumper...1 pipe , paralell pipe. Near boiler piping is ok. 1 bull head tee but not real bad. 2 Gorton #1 on each main. the old ones were plugged. Rad vents are various. some gorton D upstairs. the problem floor has 1 varivalve, 1 ventrite. edr is around 500 ft2.
@ January 19, 2011 10:22 PM in Steam stumper...Looked at a 3 unit apt today... 1 each floor. 1 steam boiler. T-stat in the bottom unit. strange oddity is that the 1st floor apt does not get heat ... all 4 rads cold but the risers to the 2nd and 3rd are piping hot. I replaced the main vents a while back and can hear them panting. I have a varivalve in the back bathroom rad and still no change.... strange thing is that the riser to the 2nd and 3rd floor and just inches away from the 1st floor rads.. all piping is insulated. ty,kpc
@ January 18, 2011 7:53 AM in valves used in hydronic boiler systemsresidential situations a ball valve is fine. Gate valves should never be used to throttle.... that will wear them out in no time.
@ January 17, 2011 11:49 PM in PIPES KNOCKINGa number of things. Too high a water temp., too little pressure, air in the lines, improper piping or expansion noise from the pipes rubbing up along the wood....kpc
@ January 17, 2011 7:42 AM in Removing air valves in one pipe systemmay very well run into is that the steam will "pour" out into the room. This will not condence and return to the boiler. You could end up w/ adding water to the boiler where you did not have to. Also steam could very well burn an unsuspecting person.
@ January 17, 2011 7:39 AM in Buffer tank control...Trying to wrap my head around the best controlling stategy... System has two zones. 1 w/ panel rads the other w/ Raupanel. 30 gallon buffer, and a Onex combi boiler.Trying to reduce the run time of the onex . Maybe I am missing the piont of the mod/con. ty,kpc
@ January 17, 2011 7:33 AM in advicewould be... depends. If you have Finn Tube baseboard, then a Biasi /Solaia /Trio/ Pensotti 3 pass that is Low mass. If you have cast iron rads then maybe a Buderus 115. Either way a 3 pass boiler is the way to go. The installer is the key. Ask for referances and examples of their work.
@ January 16, 2011 6:56 PM in adviceMistaken. The MPO is a new design, Mfg, and a step forward in a lot of respects. I have heard nothing but GOOD reports The issues were on a V7 model. It is a good unit.... I would install it if I could readily get a hold of it. kpc
@ January 16, 2011 8:20 AM in Hydronic piping layoutmeans to have the system circulator pumping away from the extrol/diaphragm tank. This arrangement is better because it allows the system to run at a pressure that will keep air more or less in solution and not bubble out into the piping creating air locks and noise. Many systems are pipied w/ the circ on the return side of the boiler effectively pumping toward the extrol tank.
@ January 14, 2011 10:04 PM in Buffer tank control...What would be the best aquastat controller to use on a buffer tank that has a mod/con boiler driving it?
@ January 14, 2011 7:54 AM in Burnham V13A oil boilerI would stick w/ the 1.25" header. The 1.5" would be overkill. How many zones? how lond is each zone? What is the Application? That would determine your circulator size.....kpc
