@ March 19, 2014 8:59 PM in compressor

This is a deli with a few r22 split ac systems, single phase. but the systems that the customer is most concerned about is the medium temp walk in box (r22) and the freezer (r404a) both 3 phase....the walk in box i replaced the compressor (burnout \case grounded) about 8 years ago and all seems fine...i just diagnosed the freezers compressor case grounded....the new compressor has a oil eye in the crankcase...the meter is electronic from fieldpiece. thanks Paul S

I've heard of a way to use a megohmeter check compressor windings. I want to provide a good customer of mine some peace of mind from compressor breakdown before it actually happens Thanks Paul S

pool heater

@ March 16, 2014 8:47 PM in pool heater

I recently got asked by a good customer of mine if I can use his steam boiler to heat his pool.i have seen some tekmar setpoint controls that show a heat exchanger off of a hot water boiler. Can the same be done with a condensate loop off of the steam boiler? Thanks Paul S

Your welcome

Goodluck Paul s

I came I would give you a proposal for the work. ... Then if you want you can send that to the other contractor. ... From my experience any work I have corrected resulted in the customer just paying me, forgetting about the other contractor. ... or they took them to court. If they really don't know steam and they know they messed up then they should do the right thing. ... But very few people do the right thing. Paul s

This is a drop header. ... which is that special piping arrangement that most of us use Paul s

Tell them

@ March 14, 2014 12:07 PM in Sight glass "empties" when boiler is firing

Is not installed by the manufactures specifications. And I hate to say it but any plumber that pipes a steam boiler like that had no business working on steam systems.... The manufacture will state a minimum of how it should be installed. ... And that's not even close Paul s..... The pic below shows a steam boiler piped at what the manufacture States. ... Most of us on this site pipe our boilers worth drop headers. .... It's a better way to achieve dry steam... most manufactures do not state this set up.... But it's the wayi would pipe all steam boilers

Thatcher heating and air conditioning. ...I believe they go out there. ... You can find them in the "find a contractor"section above Paul s


@ March 14, 2014 11:32 AM in Sight glass "empties" when boiler is firing

Boiler is piped completely wrong. ... There is no header. .. The equalizer is undersized which could be the problem. ... You needa total repipingby a good steam pro.there's a bullhead tee right above boiler. The piping should come a minimum of24" above the top of boiler. ... The return is piped incorrectly.. Where are you located? Thanks Paul s


@ March 13, 2014 9:51 PM in boiler

Is a condensing boiler always the way to go? For example a series loop baseboard system VS. A old two pipe system with big column radiators. Will the boiler always condense with the baseboard? Thanks Paul St.


@ February 26, 2014 10:32 PM in Apologies!

On a downflow application with a warm air furnace and a standard evaporator coil. .... Where should the coil be placed on the supply? Can it be installed on the return? If not why.... Thanks Paul S

Thank you guys for help. .... I will post pics when job complete Paul S

false water line

@ February 21, 2014 3:14 PM in false water line

I have to build a false water line on a upcoming boiler replacement.... But I will not be able to bring the inverted loop up 4 feet per dan's book the lost art. ...I will only be able to go up 30 inches to the top of the inverted loop seal then I have the 28 inches for the "A" dimension. Will it work as it should? Do I have another option if it can't work? Thanks Paul S

delta T

@ February 9, 2014 7:51 PM in delta T

How does a higher delta T affect heating? I know the higher the delta t the lower Gpm at a certain amount of btus.... For example 100,000 btus 20 f Td = 10gpm and 100000 btus at 30f td is 6.6gpm....on condensing boilers installation manuals they always show a pump abs pipe sizing chart. ....I always use the 20f it usually results in bigger pipe and bigger and expensive pump. ... When should i use higher delta T? Thanks Paul S

Hydro seperator

@ February 9, 2014 7:13 PM in Hot Rod,caleffi hydro air seperator vs p/s piping

I have this job in progress now. ... First time ever using it. ... boiler is peerless purefire 110.... pipe size is 1" 1/4".... Hot Rod , should I have used bigger pipe for the systems supply and return headers? For future knowledge Paul s


@ February 8, 2014 10:09 PM in Will Series-100 push water farther than NRF-22?

I don't know what you have in btus, GPM, type of system etc. .... But here's an example 100 series @ 5ft hd =23Gpm .... nrf-22 @ 5ft hd= 14gpm.... so yes 100 series moves more water.....Paul S

Hydro seperator

@ February 5, 2014 7:26 PM in Hydro seperator

Can anyone explain the benefits on using the caleffi hydro seperator.... Over usinga standard setup... Or Just how youguys liked it.....Tomorrow I will be using one on a peerless purefire condensing boiler install. ...Thanks Paul S


@ January 28, 2014 3:08 PM in No flow?

the baseboards were indeed blocked by a bunch of junk that the tenants put there....i opened all dampers and moved everything....previously with the same baseboard the home was heated by a single boiler and the basement, 1st floor & 2nd floor were ALL one series loop of 3/4" baseboard, and it worked correctly. im measuring delta T with a digital strap on thermometer at the supply and return of boiler.going back tomorrow.... Paul S


@ January 27, 2014 9:19 PM in No flow?

What is the max gpm that can flow through 3/4" pex? All I need is 23000 btus .... explain if I'm wrong.... Don't I need just 2.3 gpm? Paul s

No flow?

@ January 27, 2014 8:52 PM in No flow?

I went on a service call today " not enough Heat" area will not get above 65f.... It's a series loop baseboard system 3/4" baseline 2000...This home has 2 hot water boilers 1 for the basement and First floor and the other which has the problem is for the 2nd floor. .... customer called me because the company who installed this system could not fix it..... previously the home had just one boiler which heated the whole home. ... customer wanted to separate the 2 floors. ... The 2nd floor has a heat loss of 23,000 btus..... There is a total of 55 feet of 3/4" element. .... total loop length I estimated about 150 feet.... The loop is ran in mostly 3/4" pex with some parts using 3/4" copper. ....I counted from what I can see about 37 3/4" pex elbows and 12 copper to pex adapters. .... boiler is oversized 130000 btus.... boiler is piped properly pumping away from expansion tank on supply. .... No air in system.....The pipes get hot but there is very little heat radiating from baseboard elements. ... system pump is a 008... temp drop across loop is about 5f... No flow. ... need bigger pump? .... Paul s


@ January 26, 2014 2:36 PM in No Heat on Gas Furnace

We have on this furnace. ....I may be wrong unless you post pics. .... fan center. .. which operates correctly because the fan came on when thermostat was set to "fan on"..... fan limit seems fine because when furnace is cold left side of limit which is the heating fan speed circuit is in the open position where it should be and the right side of limit is in the closed position. .... The fan came on when you hit the button on the fan limit because all that does is Manually make a switch to energize the fan. .... check to see what safety is open. ... Roll out switch. .... spill switch etc. .... bypass thermostat manually. .... And when you check for 24 v at gas valve make sure both wires are on gas valve coil so you can make sure that a common is not lost Paul s
