@ January 5, 2014 1:38 PM in New Lochinvar Knight Questions / Concerns

the info i posted came from lochinvar.

if you have the ups26-99f,it is listed for use on the two smaller sized boilers.

06 9.8 27 1" UPS26-99F*

151-14.0 gallons per minute at 20ft/hd and 1" pipe UPS26-99F

the 211 calls for a ups32-160

211-19.6-gallons per minute at 29ft/hd and 1" pipe- UPS32-160

you look at the ft/head and gpm,and i think you need the one lochinvar specs,and if you have 1 1/4 pipe with those smaller pumps,this could be a problem.

if possible,install trvs on as many radiators as you can.

nozzle size

@ January 5, 2014 10:59 AM in Odd burner recycle @ startup since control replaced with R7284

If you can downsize the nozzle and still maintain the heat in the space,it really won't hurt anything,and may save you money on your fuel bill.


@ January 5, 2014 9:40 AM in New Lochinvar Knight Questions / Concerns

It is hard to tell from the pictures about the piping,but the return as you sid may not have to be piped as it is as this is a condensing boiler? was a heat loss calc done? one thing looking at the super brute specs is that it seems to be a little for your application. lochinvar specs;T/HD Minimum Pipe
Grundfos TACO B & G Armstrong
81 7.5 24 1" UPS26-99F 0011 NRF-36 E7
106 9.8 27 1" UPS26-99F* 0013 NRF-36 E11
151 14.0 20 1" UPS26-99F 0011 NRF-36 E7
211 19.6 29 1" UPS32-160 1400-50 PL-55 E9*
286 26.5 15 1-1/4" UPS32-80 1400-20 PL-36 E11

look at 211 line-it calls for a taco-ups32-160, which is larger than the super brute.
the super brute specs are for a 20 degree delta t,and you are seeing 35 degree delta t. also on the lochinvar specs,the pump specs are for 1 inch pipe. if it is 1 and 1/4 pipe,you may have to go with the next size up pump.

the install looks nice,but with a gravity conversion,the larger old pipe sizes can cause lots of flow problems. is the boiler set up for out door reset?


@ April 18, 2012 8:37 AM in When is it skimmed enough?

One of the problems with the newer steamers is that the steam space may be a bit smaller,which makes the near boiler piping even more critical. if you do the stove test and it appears that the impurities are gone and you still have some movement in the sight glass, it could be piping issues.


@ March 25, 2012 5:30 PM in Water softener use for a steam boiler - good idea?

generally ,in residential boilers softners are not used....but the key to this question is;
 ' is there any benefit to a softener is quality of water going into boiler is very hard?.
if the water is very hard,most boiler manufacturers,even residential do not want very hard water going inot a steam boiler. I would say if you have excessive hardness, it would be a good idea to have  a softner.
even residential steam boilers require make-up water. so really hard make-up water is not good....[u][color=#0066cc]Reply[/color][/u]if the boiler is a steel boiler,then it would not hurt to have softner.

generators and circuit boards

@ February 19, 2011 6:44 PM in Buderus won't run on generator

I posted on this topic before. I found that many newer furnaces and boilers with a circuit board need a very good ground.if your generator does not have a ground.(most have neutral and ground need a ground(hooked to a grounding rod) or in an emergency only,use the hot and the neutral from the generator,but use the ground from the existing electrical box. ( disclaimer)-the use of the ground from the house box should only be used on an emergency in essence I have tried  to run a furnace more than once on a  generator,but it would only fire when hooked up with the house ground.


@ December 19, 2010 12:39 PM in Reillo 4 section Burnham boiler

It has been a few years since I have worked on oil may have a little too much air.....many times it is hard to get a 0 smoke reading,if you get a trace,and it is steady ,no rumbling,you may be ok. i would try cutting back on air,also check your electrode settings again. I have had good luck by upgading the transformer to electronic ones that have a higher voltage output,it helps with smooth ignition.


@ December 17, 2010 7:31 PM in Modcon & Hydro Air – Big Mistake?

It will be worth the investment to install the aquastats. You may find that with the aquastats shutting the fans down,allowing boiler to catch up,should be a big benefit to others said,the coils may have been sized for 180 degree water....


@ December 9, 2010 7:30 PM in Condensation problem in Inducer blower housing on RUUD 90%

those tubes coming off of the inducer must be checked,and possibly shortened,so that there is no trap to allow water to accumulate. You also need to check the installation instructions on the condensate trap going from the furnace to the drain. check drain lines,or if it goes into a pump,make sure the pump is working,and the outlet piping from pump is clear.also check the installation instructions on the vent pipe and make sure no obstructions,and that it is pipeper instructions,and that it does not exceed the specified maximum length...

Tekmar 256

@ November 25, 2010 9:24 AM in Tekmar 256

having never used tekmar,I am looking at this controller. Are they reliable? seems like a decent control. Any input good or bad appreciated.  sorry should have posted in the main section....

big problem

@ October 24, 2010 4:52 PM in Navien Heat Exchanger Problems

I posted before on this,I had a situation that happened in a commercial building where a large hot water storage tank lining was destroyed by using soft water.most hot water tank manufacturers do not want soft water being introduced into their tanks. 

steam control

@ September 29, 2010 12:01 PM in steam control

Does anybody have any experience with a control by exquisite heat inc,from pleasantville new york? any info apprecited.mainly looking for anyone who has one and if it has worked well/and saved money on fuel costs.

ddc controls

@ July 18, 2010 9:14 PM in The Dreaded DDC control question

what do you need to know? how many boilers?hot water or steam?how many aihandlers,etc


@ April 2, 2010 5:03 PM in Question for the experts?

I have never seen it done on hydronics in a commercial setting...but....I have seen it done an airhandler,with a ddc(direct digital control) energy management system. I had a problem with an office space that had lots of windows on the exterior.the single large airhandler also served interior the time the space temp sensors opened the chilled water valve,it was too I looked at the return air,and as soon as it got warm,I opened the chilled water valve 100 percent.It seemed to work. you may be on to something,depending on application,and specifics.


@ March 25, 2010 3:43 PM in Sudden Temperature Rise and Drop

even though the boiler is fairly new,you probalbly need to have it cleaned,and checked,with a combustion efficiency test. if the boiler efficiency test is good,then you have system problems.


@ March 25, 2010 3:35 PM in Sudden Temperature Rise and Drop

in the colder apartment building,you may have to adjust setpoints for day and night to a closer differential. ie-66 degrees night,and 69 day. you may also have to change times.maybe 12 midnight night setting and 530am for can see on the day i mentioned,that it takes a long time to satisfy all sensors,this is telling you that the boiler has to worker longer and harder to satisfy the zones.what about sensor placement?


@ March 25, 2010 2:05 PM in Sudden Temperature Rise and Drop

the near boiler piping should be corrected as it may contribute to the problem. insulation will also help. what I see is that 0n 7:43am,all areas,apartments(zones) are calling for heat at the same time at 29-05 address.with an undersized boiler,and a newer modern steam boiler,you do not have a larger steam space in the boiler,thus causing the sudden call for heat,with no cushion,to cause the boiler to work to make up for 29-01 there is no such call for heat at the same time,from multiple zones,and you have a larger boiler.back to 29-05,how does this system call for the boiler to run? can you put a runtime meter/sensor on the boilers? can you adjust the differential on the system to allow 29-05 to come on a little sooner? need lots more info on how the system is configured. maybe you can use an averaging temp at 29-05 to get better control.


@ March 15, 2010 8:23 PM in Navien Tankless, A BIG MISTAKE!

It has been discussed before,if your sister had a water softner using salt for regeneration,it could have caused the problem. I worked at aa large commercial facility where a softned water was used to feed the water heater,and it caused tremendous damage to a lined tank. you should check with navien to see what the acceptable limits for softned water are. most manufacturers do not want soft water below a certain hardness...I mentioned this to someone else,and sure enough the water was below the recomended levels of hardness causing big problems.


@ March 6, 2010 1:39 PM in Hydronic Sidestream filters? & Dirt seperation/removal

I have had good luck with the type that looks like a pot-feeder,(canister) from mcmaster has a metal strainer,that a 'sock'filter fits over.they are very low tech,but I have used them a few places,with good luck.


@ March 2, 2010 8:03 PM in PRIME AND SURGE

the key could be that you lowered the firing rate......if you go too low,this could be causing the priming. did this just start since you downfired boiler? you will probably need to incresae firing rate to get a steady water level. if you did not add a laod to the boiler,downfiring too much can cause the boiler to prime....

priming and foaming

@ March 2, 2010 4:17 PM in PRIME AND SURGE

I have never seen these conditions caused by traps. is this anew installation?was boiler skimmed? was a signifigant new load added? priming,is normally caused by a high load condition,it can be a sudden load,causing the boiler water level to rise erratically.foamimg,a different condition,is usually caused by dirty,or contaminated could have a combo of both,if a new installation.need more info on boiler,piping,system,etc,etc.....
