@ November 15, 2013 12:08 AM in ThermostatIt is obvious from your frequent posts on this issue the you prefer to have the house warm. I think that rather than saying "it feels like 65", you should simply raise the thermostat until you are comfortable. Problem solved! Who cares what the t-stat says?
@ November 14, 2013 9:04 AM in Weil Mclain Ultra/DHW Issues againIt is sounding like you have an air problem. You have an older bladder style expansion tank. You should not have an open air vent in that system.
I keep asking the same question, what changed?
The system has worked for a while and now it does not.
What is he boiler side water pressure?
You may be to the point where it would a good idea to get some local help on this one.
@ November 13, 2013 11:50 PM in Weil Mclain Ultra/DHW Issues againWhat is the boiler setpoint temp?
@ November 13, 2013 11:20 PM in Weil Mclain Ultra/DHW Issues againIf you disconnect the DHW wire and turn up the heat does the boiler heat perfectly?
If you jumper the DHW wire does the DHW work perfectly?
A DHW aquastat that is going bad and not making a positive open/close can cause a bunch of electrical gremlins. I am not sure your observations about circ and firing are abnormal. Modern boiler controllers do all sorts of things during normal operations that don't make sense at first. The fact that the boiler is getting stuck in DHW mode makes me think aquastat.
@ November 13, 2013 10:15 PM in I got the bill letter from the maintenence office.Be very sure you document every part of this very carefully.
I would have a record of every interaction you have had with this company. Include times,dates.people present and any quotes that you can think of.
You need to be proactive and take this up with your local housing board. They should be able to advise you as to the local laws. The video you have should be very convincing.
I would send the management company a certified letter stating why the bill will not be paid.This will give you ammunition should the bill be sent to collections. I would also let them know that you will be asking for a refund on your rent for the nights the apartment could not be occupied.
I would copy the housing board on all future corespondents with the management company.
Are property managers licensed in your State? I would contact the licensing agency as well.
This battle will be won by you if you document it correctly.
Do you have a lease? Is any of this covered in it?
Try to keep your emotions out of this, you do not want to give the authorities any reason to think you are being unreasonable. Just present them with the facts and ask for their advise and assistance.
Is it possible to find out who lived there before you? They may have had the same issue.
@ November 13, 2013 2:07 PM in Weil Mclain Ultra/DHW Issues againYour domestic water issue is completely unrelated to the boiler expansion tank. Do you have an aquastat or is it a sensor?
First off, fix the DHW issue.
Is the leaking valve on the water heater or the boiler?
If it is on the water heater it is caused by the tank being too hot. This will resolve itself with the new aquastat.
@ November 13, 2013 12:48 PM in New Boiler install Weil Mclain WM 97+ need operation help?Dan,
The whole idea with the primary secondary is to insure adequate flow to the boiler. When you close the valve, you are putting the boiler and system circs in series.
That being said, it is difficult to get a wide delta t on the primary loop with a firetube exchanger. There is so little resistance in the boiler that even at speed 1, it is still over pumping. There is quite a bit of talk on here about using a delta t circ in your application. I have not tried it.
The best way to increase your efficiency is to lower the temps on your outdoor reset curve. If you can get your temps down on most heating days you will greatly increase efficiency. You could likely run a curve from 110-120 on the warm days to 150-160 on the coldest days. It all depends on the sizing of you radiators.
@ November 13, 2013 9:33 AM in New Boiler install Weil Mclain WM 97+ need operation help?Yes, you want to run that boiler as primary/secondary.
What type and speed circ is on the primary loop?
What type of heaters do you have?
What is your outdoor reset curve set to?
@ November 12, 2013 1:56 PM in Weil Mclain Ultra/DHW Issues againDo you have an aquastat or a sensor on the DHW.
Disconnect the DHW wire to isolate the issue.
@ November 12, 2013 9:34 AM in Testing a 15psi pressure safety valve on my boilerAh, you have steam boiler.It will not do anything until the boiler is pressurized with steam, even then there should not be much pressure involved.
I would post a picture of your install along with the boiler rating plate in the "strictly steam" section. Those guys can check to see if it is correct.
@ November 12, 2013 8:59 AM in Testing a 15psi pressure safety valve on my boilerA 15 psi boiler relief valve is an unusual item. Most residential systems have 30# T&P.
Maybe you should post a picture. These are very important to the safe operation of the boiler.
@ November 12, 2013 1:20 AM in gas hot water system will not fill with h20Will water pass through the backflow or prv/fill valve.
The fill valve will usually act like that if there is no pressure.
@ November 12, 2013 1:01 AM in Radiant floor heat not heating properlyThere are some problems with your system
Your boiler is piped mostly correctly.
The boiler has an internal primary heating circulator. There should be a check valve on the primary heating loop. I don't see one. One inch is fine for the primary on the 110.
On the secondary, I am not sure which circ you have. 1/30 HP is way too small for radiant loops. I have not heard anything about the outdoor reset curve?
The insulation is adequate. The tubing is a little light but should be workable.
I would make sure you have a check valve on the primary loop.
I would try to determine the loop lengths and size the radiant circulator correctly.
Once you have proper circulation, I would adjust the heating curve on the boiler until the heat is comfortable.
Sure the boiler is oversized and there are some install and design errors.This certainly not a horrible system and I believe it can be easily corrected
@ November 11, 2013 2:14 PM in Combining 2 zones into 1?The problem is that the boiler control does not have a setting that will allow CH1 to be enabled at the same time as CH2 and for CH1 to be enabled separately.
It is just a limitation in the internal programing of the boiler.
@ November 11, 2013 10:57 AM in Combining 2 zones into 1?I think you will need a 501.
If you look at the tables in the trimax supplement, you cannot get the CH2 circ to turn on the way you want leaving the CH1 controlled correctly for your piping.The 501 is not expensive and will take care of the issue.
The 501 will control the circs with the TT wired to CH2 demand.
I would still use a curve for CH1 and CH2. The mixing valve would function as a "not to exceed".
@ November 11, 2013 9:04 AM in Rinnai tankless woesWhat size and type of gas line are supplying the unit?
@ November 11, 2013 8:44 AM in Combining 2 zones into 1?It looks like the relay has the capacity. Unfortunately, I don't see that the logic on the boiler control is set up for that with your existing piping.
It would be easy to keep the zones as is using a sr502 or combine them with an sr501.
I am glad thing are coming together on your system,
@ November 11, 2013 12:05 AM in Combining 2 zones into 1?The CH2 can handle up to 2.5 amps. What type of circs are you looking at.
You may be able to power both.
@ November 11, 2013 12:00 AM in Hydronic Replacement Boiler SizingThe Burham alpine has the exact same exchanger that you WM had.
@ November 10, 2013 11:28 PM in tekmar 256Paul,
The 256 will control the boiler with outdoor reset. You can set the boiler minimum output.
It is not designed for two temp systems or boiler protection.
@ November 8, 2013 9:44 PM in Spring check valve ? on triangle tube.I would try for that. I bet you get more like 10
@ November 8, 2013 8:56 PM in Spring check valve ? on triangle tube.I would try spped one and then double check the supply/return delta t
