I do the same thing, when I haven't seen something in a while

@ May 16, 2014 7:00 AM in 3-wire Nest to WM EG boiler?

yesterday I had to wire a 6006 into a 8148j so they had a low limit, I could not for the life of me remember exactly how to do it, I had to look it up but couldn't find the info anywhere, so I had to trial and error it until I got it rite, 3 trys was the magic number, I know with the 8148a its simple just wire R to r1 take out the jumper to 3 and wire 3 to the center wire of the 6006 then the bottom wire to the top of the 8148a's limit dials terminals, with a j its almost the same except, remove the jumper from w to z and jump z to tp hooking them to the center of the 6006, confusing to say the least, now I wont do it again for 8 years and I will have to figure it out all over again... Ill have to look up this post to remember...

The vertex is going to cost as much

@ May 16, 2014 6:48 AM in New water heater

as an inexpensive gas boiler {williamson} and its not a boiler its a water heater. Is their hydro air unit still in good working shape, I would check the coil, get the btu and temp ratings, do a heat loss, and install a small ci boiler, they have already fell for what I call the "brochure bs" once with the system they have, no reason to do it to them again with a navian, lol... I really don't like Navian, just personal preference from what I see and my experiences, I am sure there are units out there that will last 15 years, I have just yet to see one...

A ci boiler, with a 40 ga water heater {if they can afford a rinnai tankless that would be a plus} would do this customer well, the tank may only last 5 years but if you do the boiler rite {pri/sec} it should see 40 years with out much service..

I am just a ridgid guy

@ May 15, 2014 10:27 PM in Time for a new threader....

Not sure why, just grew up with it in my hands and feel comfortable with it... Lifetime warranties don't hurt either, I had a shop vac that was at least 8 years old, I called up to see how much a new motor was because the ss can and plastic housings were all still good, but the motor dies {we used it a lot}, they said "its free", I got it in about 2 weeks, threw it in and still have that vac...

Also I had a ridgid 300 stand wear out, just opened and closed too much I guess, sent me a new middle section and hardware kit for it, no questions asked...

Obviously they are not going to cover my second hand 300, lol but maybe I should give it a shot...

Anyway just to add insult to injury one of my pipe welders smoked today, just a puff of smoke and no longer works, probably some kind of inverter failure....

That eg should be 24v

@ May 15, 2014 7:33 AM in 3-wire Nest to WM EG boiler?

I believe. if not paul is correct you can use a sr {the tacos have 24v aux} or depending on the setup the nest can be configured to just be powered during a call for heat {I dont know how well this works}, but if you have a milli system or something that you can not grab 24v from {or your manufacturer doesn't allow it, I think Buderus states it will void warranty to use power consuming controls off of their systems} you can use a RIB...

heres a quick drawing, you will of course need a 24v trans and a rib spst... BUT the EG should be 24v, now if wm voids warranty for using a tstat with a load I don't know...

RIB u1c is the rib number I believe and any 24vac sec 120v pri transformer will do the trick, I have used the off the shelf 40va's a bunch of times to power t-stats... My coal furnaces entire control system is ran off a 40va with rib's, controls all the tstats, feeder motors, zone damps, ect...

Thats a Complete Heat System

@ May 15, 2014 6:20 AM in New water heater

Looks like an HM30, strap in and hold on, lol they are trash...

The heating module works like a boiler and the furnace is like a first company hydro air unit...

I replaced a bunch of them in a few condo/townhouse complexes.. They are trouble and expensive to repair, I believe Lennox settled a big class action because of them...

Anyway, you have a few options, replace the unit with a gas boiler and water heater, then use the water coil module just like you would a first co unit, or you can install a new 90+ furnace and a water heater, ect...

I have done it many ways, the hydro coils aren't great so I try to talk people into completely ripping out the lennox stuff and going with either a new furnace and water heater or new first co boiler and water heater, you can obviously do the furnace and water heater cheaper than a boiler, first co, and water heater...

I personally would try to sell them a nice Armstrong 97mv with a Rinnai RU series tankless, simple efficient, and you should be able to get it all done in less than a day... You get a lot of upsells too, like uv lights, steam humidifiers, air filters, ect... Plus depending on your local' there will be a few rebates for them, variable speed ecm, mod con 90+, condensing tankless, programmables, ect.. That would be over $1000 in rebates around here..

@ May 14, 2014 7:35 AM in 3-wire Nest to WM EG boiler?

I seen this in controls, but wasnt sure what you were asking, I am guessing you want to power the nest so it will charge itself?

If so wire rw as you would normally and wire c to the other side of the transformer...

On the nest I believe it is the top W, then c is in the middle, and then RH is at the bottom all on the right side... All you are doing is giving the t stat both legs of your 24v instead of just one leg, in other words normally a 2 wire tstat just has say the negative leg and it breaks it or makes it, it acts like a switch...
Now you want to power the tstat with it so you need both legs pos and neg, so you need to bring that up from the source of the 24vac, so wire it to the other leg... Find the transformer, and hook C up to the missing leg...

What is the heatloss

@ May 14, 2014 6:12 AM in Hot Water Options

Like I said a couple times, you need to do a proper heatloss calc and then take a walk around the apartments and see what their DHW load is {dish washers, washing machines, bath fixtures, ect}. That 140K is most likely way over sized..

Now as far as not running the boiler in the summer months, I like the idea, BUT not at the cost of having to maintain an additional pair of hot water tanks...

If the current 40 ga indirect is working in the winter I also don't see the point in going up to a 60...

If the 2 electrics are in good shape and working leave them alone, if they have no complaints about the 40 gallon indirect then either install another one or if that one is still in good shape leave that alone too... You would do your customer more good, just installing a proper sized boiler with their existing DHW system...

Now if they do actually have a 140k BTU heat load and you want to do something "fancy", you can install dual boilers, I have done this many times in larger homes

Last year I installed dual OWT3's {ci oil fired with tankless}, the buildings heat loss was rite under 150K, I set the burners up for the load then wired them so burner 1 would only fire until 2 was needed, I piped them so both boilers were hot all the time, primary secondary with the primary loop going in and out of both boilers. I only used 1 aquastat and it was placed in boiler 2's well so both boilers would stay to temp letting both tanklesses stay hot....

That gave them a lot of hot water and gave them the efficiency of running a single small boiler when thats all they needed and then in the colder months running them both to keep up with the load....

That house was very large and also 2 family {rented inlaw}, it had 7 zones and held a lot of water, I did the near boiler piping with 1 1/2" {could have done 1 1/4} and insulated it very well, I used an alpha delta P pump for the primary loop and 007s for each zone {piped in with closely spaced tees}...
I spoke to them about a month ago and they said their automatic delivery company told them they were down a good amount from the previous year per degree day... Granted they were firing a 20 year old 210K BTU burnham with an amtrol 60 both of which had seen better days, but a savings is a savings..

Another plus to this is when one burner goes down you still have heat, it takes a little thinking {I have the drawings and pics if you need them} and a little more work but the outcome will be better than a single big boiler and indirect... The cost in materials is not as different as you may think though, when comparing dual OWT3's to say a G215-4 and indirect it can come out to less money in materials, the 150K plus oil fired units have a good jump in price...

The owts also get 86-1/2% eff. This would allow you to get rid of the 40 gallon indirect, and stop the stagnant water issues they are most likely getting from having the tank not flow for the summer....


PS: I'm not sure I understand what the well water difference makes in costs? I would much rather pay for city water and not maintain a well and pay for the electricity it uses... And they are going to use the same amonut of water no matter which way you go with the dhw equipment, am I missing something?

I like the ridgid 300

@ May 13, 2014 4:29 PM in Time for a new threader....

I have used the others, and the 300 gets my vote, if its setup correctly, and you use ss dies, it threads great, one person can move it around and put it up or down... The rex machine is like the 300 compact....

I have all ridgid threaders, plus I like having all the threaders matching, and I have at least 10 811a's set up with various dies...

When I say heat loss

@ May 12, 2014 9:06 PM in Hot Water Options

I mean for the space heating.

You want to come up with an accurate number for DHW and Heat..

So say each unit needs 5gpm at 70 degree rise and the entire building needs 60K BTUS of heat... I would look into a small natural gas boiler with a pair of natural gas water heaters {if there are 2 gas meters if there is one, go with a larger gas fired tank for both units...

oil or gas

@ May 12, 2014 8:10 PM in Hot Water Options

Do the math for his heatloss and his DHW consumption and then I could give you some options...

It is well taken care of

@ May 12, 2014 5:37 PM in Time for a new threader....

just seen a lot of pipe in its day, this one I bought used about 10 years ago and use it more than any other, because it always ended up being closest to the door, lol...

I have a couple small pony units that we never use {690 and a 700}, I have a 1215 that I keep in my sheet metal trailer, a 1210 that I used a lot when I first got it, but I always go back to the 300, its fast, cuts great, with the carriage is really easy to use, the only downside to the machine is its weight, but with the stand and the wheel set its not that bad to move around...

Time for a new threader....

@ May 12, 2014 3:52 PM in Time for a new threader....

One of my 300's is getting old, just needed to change the switch and today when I was using it I noticed the chuck is getting loose so I just ordered a set of jaws, before this machine costs more than a new one to fix, I figure I will grab a new one, but I just got a call back from the supply house and they are almost $4000 now!!!

This year seems like I am spending a lot in equipment, I still need a couple new combustion testers too, an easy $3k, and now a new threader...

Anyone know the best place to buy a ridgid 300... I can get away with just a drive, but I would rather buy at least the drive and carriage so I don't have to rebuild my carriage, I dont mind using my stand and oiler...

What

@ May 12, 2014 6:42 AM in Are you in the market for a Thermal Imager?

LOL, I have to send my laptop into the repair center if I need a new screen protector...

message me

@ May 9, 2014 11:05 PM in Are you in the market for a Thermal Imager?

and I will forward it to you, thanks

Thank you guys,

@ May 8, 2014 9:52 PM in So far behind......

I appreciate the advice, I have a few guys working, A/C tech, Sheet metal Tech, carpenter, and helper. The jobs go pretty smooth for the most part, I am no stranger to how to run the day to day ops and get the work done... I think the stem of the stress I am feeling is my personal issues, with the house fire and my sons illness returning that is wearing me down more than the work... I just got home, its quarter to 10 and everyone is sleeping, I am sitting in my office planning tomorrow.... I just wish the days were a little longer for a few months so I could catch up...

Obviously the money is good and the reason I do it, and I tell my self things like "I am going to sub out the a/c this year" but then today I sent out 3 cooling proposals.... I am interviewing 2 techs next week hopefully I see some potential in one or both of them...

As soon as I catch up I am going to evaluate how I am running this, I am going to try to get behind the desk more and behind the wrench less...

yes

@ May 8, 2014 4:56 PM in Are you in the market for a Thermal Imager?

pip works for me plus a few other features the e6 and 8 dont have

I have a rental property

@ May 8, 2014 6:34 AM in bathroom baseboard

that the baseboard is about 4 inches from the toilet and this thing was constantly rusted, every year or so it needs a cover...
So I painted the entire cover assembly {a rusted one I didn't even sand the rust off} with this stuff called POR-15, I used the silver and it came great and now has been there for 5 years and still looks new,,, The por is self leveling so I just brushed it on over the rust both sides of the covers and it looked new, and still does... that stuff is amazing...

So far behind......

@ May 8, 2014 6:27 AM in So far behind......

I never noticed how much a few hours out of a few days each week can get me so far behind, with everything going on rite now, the house fire, my son being sick, season change work, ect. I can not keep up...

I am subbing out my AC work rite now just to catch up on the boiler work, I have 8 boilers out there delivered waiting for installation, luckily I have great customers but I am working 7 days a week, trying to work as late as possible and still not catching up, I hate having to give excuses, I just need a few more hours added onto each day...

But I am in a hard position, do I suffer through until I catch up or hire another tech? I hate to hire another tech since I don't have an extra truck for him and I know after I am caught up I will not need him.....

I have used them

@ May 7, 2014 12:29 PM in small snow melt, ideas?

but they are still a little over budget...

small snow melt, ideas?

@ May 6, 2014 9:56 PM in small snow melt, ideas?

I am pricing a job, its a tiny snow melt 150 sq ft, total, probably going to be around 300ft of 5/8" tubing with a 3 circuit manifold on a 10 plate 5x12 plate exchanger...

Normally I will use a snow melt control, but the budget in this job is not going to allow that, I have a system out there where I used a 35/45 thermostat http://www.amazon.com/gp/product/B0026S6WGK/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A1JX5VIUKL6HSF in a weather tight box tucked into the unheated soil near the snow melt with a switching relay and it works, the customer never complains, and it cost me under $100 in materials{for the control and stat}...


My question is what else is out there that is affordable and will control a snow melt system well????

Thanks

I have been doing this for a while

@ May 5, 2014 6:09 AM in Carbon Monoxide/Smoke Alarm Interlock

I offer it to customers for cost of materials on a new install, some go for it some don't.. I use a BRK 9120 with a RM4, costs under $100 with the boxes. The 9120 is a combo smoke co and seems to be very reliable. I have a post around here somewhere that we talked about this..

I love the idea and think it should be code everywhere...

sure they can last

@ May 4, 2014 12:55 PM in List of small mod/cons

It seems the older tanks {like most things} last longer than the stuff made now, but I can not count the ss indirects, buffers, electric/gas/oil fired tanks that I have replaced under warranty, and the amount of tanks I replace a year or 2 after warranty are even higher. My aunt bought a house with a gas water heater installed about 15 years ago when she bought the house the tank was 6 years old and its still there, so there are some that will last but for the most part I am not happy with what i see from water tanks...

But yes it seems some last, just its luck like anything else, My sister has a lincoln LS with 190K miles on it, 90% of the others built needed engines before 80K....
