@ April 2, 2014 10:34 AM in Weil McLain indirect hot water heater, short cycling?..I had the same problem with my indirect also. Since I work at my desk & shop in the basement I could hear it happen. I was concerned as I had installed this myself, but nothing was wrong in the end.
What I was able to do was hook up a 110V analog clock to the burner wires & view the ZVC404, clock & boiler temp with an interval camera taking a picture every 10 seconds.
After analyzing hundreds of pictures I caught a short cycle. It was nothing more than a confluence of triggers that had boiler temp just at a cutoff toward the end of a call for heat. The clock showed under 5 second burner run.
@ March 24, 2014 11:06 AM in main line water filterA few years back we had moved into a new to us place with our first ever well water. At first we just had a spout at the kitchen sink for drinking water. This was because the tests done prior to closing indicated we had 5 time the amount of lead recommended. The former owners had an under sink unit installed to alleviate that problem.
After a few months I noticed the kitchen sprayer was getting plugged up with minerals every month. I put a whole house sediment filter just after the well tank and the sprayer issue went away. Four months later I changed the filter, yikes was it cruddy with all sorts of nasty stuff. For the minimal cost of the string filters I will continue to use this filter. I can't imagine all the stuff not getting into our appliances and systems.
@ November 11, 2013 7:56 PM in Classic!It reminds me of an old trade journal story where the customer states that he can get the job for 10% less. The builder encourages him to do just that and even gives him a reference to his competitor.
The thought being that you do not need or want this customer.

That is why my default editor is UltraEdit. Been using it for 15 years plus. Good information, thanks.
I don't know what email you use but my rule is that you must know what the link leads to before clicking it. This is old fashion but, I have been a PMail user for many years. It is a desktop based email client. When I see a link I can mouse over it and view the actual link that will execute. It is so restrictive that you can not view imbedded pictures. Most emails have a "click here if trouble viewing this page" option that saves the day.
I must confess that I stopped using Firefox recently when a new release killed an add-on that I liked. It lead me to Pale Moon "Pale Moon is an Open Source, Firefox-based web browser for Microsoft Windows, focusing on efficiency and ease of use." It still supports the add-on that I like and is efficient with many fewer updates.
@ November 11, 2013 2:13 PM in CryptoLocker malwareI can believe doc & xls files because they can execute VBS and cause damage, and that goes for any MS Office application. Any txt file would need an environment to make the machine execute instructions, that will not happen with a txt file.
I use a derivative of Firefox and have the NoScript addon. This will keep any scripting language imbedded in web pages from being executed. On web sites I trust it is disabled (like my bank). This is generally a good protection against virus and malware that hang out in web pages.
@ November 9, 2013 10:11 AM in Gas companies in CT make big push into oil territoryI live in CT and saw that the plan to help gas companies did not pass because of so many complaints from people that will not benefit from this like myself.
We are in a small town and doubt that water, sewer or gas will make it to my street in my lifetime.
The public utility in Norwich will be expanding the gas lines but they bonded to do that.
@ August 6, 2013 3:36 PM in washing machine drain hose problemOur laundry is on the first floor in a new addition put on the 1959 home. I used a Watts Intelliflow shutoff retrofitting the single control shutoff to use this surface mount unit. They are not cheap, but when you consider the cost of an overflow it is a deal. And you get a water sensor to boot.
The Intelliflow senses when the washer is on and only then will the water flow. Combine this with metal jacketed hoses and you have great protection.
@ May 26, 2013 2:22 PM in By special request.close the drain before taking the faucet apart!
@ May 13, 2013 2:09 PM in Need opinions on kitchen faucet brandsI always tell folks to stick to brands that the parts are carried in the local hardware store. If you can't get the parts the faucet does not matter. That has been my experience in the 20 years I fixed faucets.
@ May 8, 2013 10:52 AM in Taco on Fox Business NewsI love that some business leaders did not give up on this company. Thank you John White for making a great product line with local people.
I am not far from the plant and will have to visit someday.
Thanks for sharing.
@ February 18, 2013 2:47 PM in Spare PartsI have a single TACO 007-F5 in my system. Is it worth it to have a spare around?
@ February 2, 2013 4:32 PM in Please define short-cycleI recently put in a second loop that was a Crown MS-40 indirect. Since my workshop is in the basement also I am around the boiler much of the day. After installing the MS-40 I noticed a short cycle of 10 seconds or less.
I took the cover off the L7224A aquastat put an analog 110v clock wired to the burner feed and set up a camera that takes a picture every 10 seconds. It took several days and thousands of pictures put I found the culprit to be nothing more than a normal sequence of events.
The zones are controlled by a Taco ZVC 404. In the series of pictures I could see the call for heat, the burner fire and then finish a normal run with the temp over the HL setting, Still on the heat call the circulator brought the temp low enough for the burner to fire again and then 8 seconds later the call ends and everything is off.
I saw more than one of these sequences even with the indirect taking priority and passing back to the heat call.
With the clock showing seconds, the 404 LED's and the burner temp on the aquastat it was a great learning experience.
@ January 18, 2013 4:25 PM in Short CycleI have a time lapse camera I
bought last summer to capture the addition we had put on. I set this camera to take a picture every 10
seconds between 6:00AM and 10:00PM. The
picture captured shows the Taco ZVC with two active zones; #1 heat and #4
priority DHW. Also in the picture is the
digital boiler temp on the Honeywell L7224A and a cheap analog 110VAC clock
wired across the burner 110. The clock
lights up and the second hand moves to verify the burner is on.It takes some time to review
all the thousands of frames I upload each morning and afternoon. Today I caught the short cycle I had heard
that prompted this research.
During a heat call the temp
went over HL 160 and the burner went off.
The heat call was not satisfied yet so, it kept dragging the BT down till
it went below 150. The burner fired
again and the call was satisfied. The
burner was only on 8 seconds. Apparently
once the call is over and the BT is above LLD 130, it is off, no matter when it
I think I have my
answer. Thanks for the replies.
@ January 14, 2013 3:17 PM in Short CycleI just set up a camera to catch what is going on by taking a picture every 10 seconds. I'll report back when I have some data.
The tstat is a Honeywell RTC 8100. Did not see any setting other than system type which I verified a set for gas/oil.
@ January 14, 2013 9:10 AM in Short CycleThanks for replying.
I did more research and noted the ASC value is off on the L7224A. I may try setting it to 2 minutes to see if that helps. As I recall the boiler had not been running, then the short cycle occurred, and maybe 10 minutes later normal call for heat.
@ January 12, 2013 2:34 PM in Short CycleA few weeks back I posted in the DHW thread. Since then I completed the installation of the Crown MS-40. I have noticed a few times and I mean no more than three, while working at my desk, one room away from the boiler, I can hear the burner cycle on for about 5 seconds then off and nothing happens after that until the next call. Today I went to the ZVC and none of the zones were active.
Any clue what is going on?
The attachment describes what I have.
@ December 17, 2012 11:10 AM in Installling indirect water heaterIs it OK to mount the ZVC on the boiler housing. I can't see any other place that would work as well.
@ December 4, 2012 7:15 AM in Installling indirect water heaterI will look at the suggestions. I am still gathering parts.
We bought this house just 18 months ago and the boiler was new. I don't see any change for years.
On my update list is an outdoor reset module to save on fuel in the warmer months.
Anyone care to comment on what would be settings for the low and differential once the MS-40 is installed?
@ December 2, 2012 6:05 PM in Installling indirect water heaterOK on the T/P.
What is that Taco model I'll look at it.
I have 3/4" copper fin with 3/4 Pex. One zone split into two loops, one of them 32 feet the other 36 feet.
I have attached a PDF that documents what I have. The MS-40 is not in yet, just documented.
@ December 2, 2012 2:33 PM in Installling indirect water heaterI am planning on a DIY install of a Crown MS-40 indirect water heater. I currently use the DHW coil in a Crown 120,000 BTU/hr boiler.
I have the MS-40 on site. I still need to get T/P valve rated at 181,800 or higher, 2 of the Taco Z075C2, 3/4" Sweat Motorized Zone Sentry Zone Valves and to make the MS-40 priority and supply 24VAC for the zone valves I need a Honeywell R8285A Control.
I have been through the install manual and think I meet all the requirements. I only have a few questions:
1. Anything special when teeing off the supply and return 3/4 copper to add the new zone?
2. The Honeywell aqua-stat L7224A currently has a low limit of 180 with the differential of 16 and no other DHW settings turned on. What should I consider for the settings after the MS-40 is connected?
