now there may have been a defective tank. but filing the system....no.

@ February 10, 2011 5:46 PM in Solia boiler not heating up

two 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.

Have 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 6, 2011 8:46 AM in Solia boiler not heating up

few 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.

well you bled....

@ January 21, 2011 8:02 AM in 2nd water heater installation

is 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.

thanks...

I will keep at it. The big rad in the living room is a bit better w/ the varivalve.

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.

Steam stumper...

@ 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 17, 2011 7:42 AM in Removing air valves in one pipe system

may 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.

you are correct...

@ 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

I guess the answer.....

@ January 17, 2011 7:33 AM in advice

would 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 advice

Mistaken. 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

Pumping away....

@ January 16, 2011 8:20 AM in Hydronic piping layout

means 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.

Buffer tank control...

@ 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?

pretty much the same boiler

@ January 14, 2011 7:54 AM in Burnham V13A oil boiler

I 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
