@ September 18, 2013 12:17 PM in Boiler Piping4 years ago I first came here with the same design on a house we purchased
Search " New House Q's ' for my original post & subsequent repairs.
I just purchased the twin to my original house with the same hydronic "designer & installer" so I am going to have the same repiping performed. some of the many problems are: no return water protection for the boiler, no high temp protection for the in floor tubing, 2 pumps, a 26-99 along with a 007, installed in series etc etc.
The boiler sensor is going in the buffer tank because I am using an ESBE for return water protection.
I'm not sure why I am concerned with expansion issues this time.
Thank You for the input

1st Picture is the present setup, 2nd drawing is planed mod's
@ September 18, 2013 11:06 AM in Boiler PipingIt will be a 4 pipe connection with the buffer as a hydraulic separator with a Tekmar 361 controlling an injection pump.
attached is a picture of the present setup
@ September 18, 2013 10:21 AM in Boiler PipingWhat is the best practice piping method to add a buffer tank to a cast iron boiler? The piping to the BB will be in 1-1/4 black pipe. Is there any reason to be concerned about expansion forces on either piece of equipment? Should there be swing joints between the units, if so how many? & on both pipes or just 1? I do have layout flexibility, they can be installed right next to each other, or they can be installed on either side of with the boilermate between them.
@ May 18, 2013 11:56 AM in Longest lasting indirectsHow would a Reverse Indirect perform in the tough situations mentioned above?
WATER CHEMISTRY, Hard Water and/or High Chlorides
HIGH WATER TEMP, Expansion Stress
As a homeowner with a 10 year old Amtrol 80 gal Blue Bullet, I'm just thinking ahead to have something picked out.
@ March 30, 2013 1:40 PM in Issues with & Replacement of Honeywell L8148E AquastatRocky22,
I Cant find any reference to the c-90, possibly a v-90???
Anyway your description of the symptoms sounds remarkably similar to my problems with my slantFin SX-150. It used the same control (L8148E) and it drove me & my boiler man mad trying to find out why the boiler would intermittently not fire. It was suggested to replace the vent damper & gas control too, but I resisted until the failure was confirmed. Good call on my part, because it was a cold solder joint on the L8148E control relay. Its a DP relay, and the burner contacts were the problem, so the circulator would work ok. I chose to replace with the Becket Aquasmart (similar pricing, but features are included to save$$$) check it out,
its a nice unit
@ March 11, 2013 3:42 PM in Vacation Home Heat Pump setting when awaySo to be specific, we have a Trane XE1200 Heat pump, not sure if its TXV or not. I tried to look up info from internet, but was unable to find specific info for my system.
Is there any kind of 'rule of thumb' that apply's to heating costs at 55* vs 65* ???
eg: it costs 25% more to heat to 65 vs 55 or is it more like 10% increase
Thanks again for the input
The long reheat time is why we use the BayWeb to get the house warmed up before we get there, along with power out & freeze up warnings. It saved us on a boiler out issue in Colorado Last winter. Without the BayWeb, we never would have known the aqua-stat had failed......... Until we arrived 3 weeks later
@ March 9, 2013 11:43 AM in Vacation Home Heat Pump setting when awayHi,
We have a vacation home in central Missouri. I have installed a Remote Internet Thermostat (Bay Web).
In the interest of economy, I keep the house at 55* when we are not there in the winter. This is a house we use year-round, but its an every 2 weeks we are there for the weekend type thing. I set the t-stat at 55* for 10 to 12 days then 70* for 2 days etc.
I am wondering if this is to low of a setting, my brother in law, has the house next door, similar size house, EXACT same size & model Trane Heat pump, he keeps his at 65*.
He reported that he installer told him to never turn the temp down past 65* because it was hard on the heat-pump,& was not as efficient as 65*. Now mind you, this was installed in 1999, & this is mid Missouri, where there are a lot of "old wise tails" we have the same installer, but that was never mentioned to me. The heating usage seems high to me, I can track it on the Bay Web, & our electric bill seems high also.
The unit didn't seem to have any trouble cooling the house last summer even though we had record heat for a long time, so i'm not inclined to think it needs servicing, so I thought I would pose this to the wall for help.
Thank You for your input
@ January 17, 2013 11:06 AM in Honeywell Aquastat L8148E - Switching RelayI did the failing Honeywell to Aquasmart conversion.
There is some trickiness in wiring the propitiatory vent damper harness into the aquasmart, but it can be done. It works great
@ January 1, 2013 1:29 PM in WiFi ThermostatCk out the recent wifi thermostat thread in the controls forum too.
Happy New Years:
@ December 27, 2012 1:03 PM in Circulator post purge controlAny suggested ICM part #s for adding 120V post purge pump (Taco 007) control.
I see some of the units are limited to 1 or 1.5 amp & have voltage drop, not sure if that is too close to the max rating or if the voltage drop matters for the 4 min it will be ronning each cycle.
@ December 15, 2012 1:38 PM in wifi thermostatsThe technology is definitely here now,
If you have wired internet available, look at BayWeb, although their tech service people could probably get you hooked up on wifi.
I have 3 units working in 3 Houses, they work great.
The aux input / email alert feature saved me from a frozen house & pipes when my boiler control failed.
The occupancy feature doubles as a burglar alarm, very slick
oh ya, there is NO monthly fee either.
DIYCONTROLS seems to have the lowest price http://www.diycontrols.com/search.aspx?searchterm=bayweb
@ November 19, 2012 7:02 PM in Triangle Tube Solo 110 and Smart 80Instead of 2 TT110's, (modulation rate 30K to 220K) Would it be feasible to combine a TT50 with a TT175 to get a wider modulation rate (from 16K to 230K) to limit the short-cycling problems in a setup without a buffer tank ??
@ November 15, 2012 10:41 AM in Triangle Tube Solo 110 and Smart 80One more thing to drive you & your installer crazy with...
Why would you/he be thinking of doing 2 TT110's when the combined output is greater than what you now have & you don't use more than 1/2 of your present capacity regularly .
It seems like if you like the cascading 2 boiler setup, a couple of Locinvar Fire Tube wHn085's would give you in effect a 10 to 1 turn-down with a low fire of under 17,000 btu's. to limit short cycling under mild conditions. They also have a dual boiler Efficiency Optimized Cascade setup.
@ November 12, 2012 11:10 PM in Triangle Tube Solo 110 and Smart 80Sorry to hear about your troubles, things are really a mess.
Has anyone done a heat loss with the house in its present configuration?,
Do you know if when you showered with the present system, were both boilers firing, if so for how long ??
The original install seems like it was way over-sized for the heat load, and used a boat load of pumps.
A New properly sized ModCon with Outdoor reset and constant circulation anyone?
Dump a bunch of pumps (& electrical consumption) and gain all the comfort benefits of reset. & constant circulation.
I went from something like you have to constant circulation & Outdoor reset, what a difference it makes!
You don't need the Tekmar with the modcon,
Does the snow melt boiler need replacing also?, possibility there, depending on the size, is to use that boiler to heat the domestic.
A big indirect running at 140* with a mixing valve could provide a bunch of 110* water.
I've seen it said on the forum before: size the modcon for the heat load, then pick the
I hope others chime in with input.
That tankless suggestion is a good possibility too, then you for sure won't be tempted to oversize the boiler. I have all kinds of hot water heaters, Tank, Tankless, & Indirect
Watch out on the tankless, see what the "time to hot water" is, some of them are pretty long. My indirect has priority on the boiler, but because I run reset & const circ, the house temp never varies a bit when the indirect is using all of the boiler output.
Terrible that you have to do this, but it gives you a shot at doing it right.
@ November 7, 2012 12:33 PM in Lochinvar Knight WHN155 boiler + Lochinvar Squire SIT040 indirect water tankThat boiler seems like a lot of horsepower.
My experience as a homeowner suggests that you & the Boiler Installer have a serious & LONG meeting about sizing. not enough info to say he is wrong, but the discussion you have with him will tell you if he has done his homework with regards to the proper sizing, OR if its a wild ass guess & then add some btus.
My house in the Colorado mountains (2000') has a slantFin sx150 150,000 btu 80% eff boiler operating at 9000' altitude. Gas usage MEASURED by Mark Eatherton 99,000 btu @ 80%, so, 80,0000 btus are going to the house. Coldest night of the year, 30below in Fraser, so slightly warmer in WP say 25below, 24% usage measured by my BayWeb t-stat .
My next boiler will be the WHN 055 or possibly the larger WHN085 to support all the after ski showers taken in a short time.
Knowledge is power, Knowledge save you a ton of money, & there is a lot of Knowledge on this website.
Good luck, report back with your findings & post your fuel savings too!

@ August 20, 2012 9:43 PM in indirect control setupThanks for the input Mark, I'll keep an eye on the reheat cycles, & great tip on the hot tub filling at a low pace.
My wife was out in WP a couple of years ago without me. She was sitting on the deck, looked up on the roof, and there was a huge pile sitting on the roof. Not really sure what she was looking at, she called the people who check on the house when we aren't there & do the snow plowing. Jimmy came right over, took 1 look, @ said "Thats BEAR dung mam", my wife about left her own dung after hearing that. The theory was something bigger than him chased him up there, we found the claw marks on the front porch columns. She never goes out on the deck without looking back up at the roof now.....
Planning on late Sept visit, we would love to see your spot if the days & dates work out
@ August 14, 2012 6:51 PM in Repairing Poly Pipe Under ConcreteOne of our customers at my auto repair shop has a business that repairs leaks in pool lines & pipes, its all he does. He is real busy, but i'm sure one of those guys is who to call.
@ August 13, 2012 5:03 PM in indirect control setupWell, I have made the latest upgrade to my system,
1) Replaced the failing a-stat in my Amtrol WHS-80 boiler Mate with a Johnson control A419
2) Added a Honeywell AMX101 Mixing Valve
Now I am looking for advice on how to setup the Controls.
I presently have the AMX101 mixing down to 120*
The Aquasmart control on boiler NOW is set to high limit 190* with a 45* diff.
Heating is done with full ODR Injection control with Radiant Tube in Concrete (lower level bedrooms) & tube in Gyp (Main floor rooms)
Boiler: Slant-Fin SX-150 @ 9100’ altitude. Mark Eatherton has measured the gas meter and reports 99,000 btu gas flow.
Taco 007 dedicated to the indirect.
A419 Set point to 140* with a differential of 10*
My questions arise from observation of the heating cycle for the Indirect. This is our Mountain vacation home. We drained & cleaned the hot tub, wanted to use it that night, so I hooked up the hose the the washer hot tap & filled it with hot water from the indirect.
There was no call for heat, only for hot water.
It took several tanks of water to make up that much water for the hot tub. While observing the reheat cycles, I noticed that when the Indirect tank temps were low (say under 100) the boiler temp would rise slowly & mostly stay in step with the indirect. At some point the boiler temps started to shoot up quicker than the indirect & the Boiler would cut out on high limit (190*), the pump would keep running, and the boiler would cut back in @ 145* (45* dif)and then make a run for the top again. That is when I raised the HL to 190 from 180 & maxed the diff out to limit short cycling. It stabilizes to about 6 min on, & 6 min off (HL cutout) until the indirect is satisfied.
It seems like the indirect should be able to transfer the heat better to the water tank than 6 min on, 6 min off. I never paid attention to the heating prior to the latest upgrades, mainly because You could not see the temps inside the indirect with the factory control, & I had the indirect set to 120* (or so I thought, I never measured the temps)
Thank You for your help
PS Mark, no bears in WP recently, enough rain & food in the mtns i guess
@ August 1, 2012 11:40 AM in What are my options?http://www.bradfordwhite.com/images/shared/pdfs/specsheets/553.pdf
Its a water heater with a built in heat exchanger - NOT an open system :
"Heat exchanger – UltraCoil®
Heat Transfer System—dielectrically isolated,
double wall type consisting of a highly conductive material with an NSF approved
Polyethylene (PEX) coating. "
@ April 12, 2012 1:18 PM in Warm radiant floors?Mark, would you clarify for me what you are referring to as a radiant panel heater. Are you talking tubing in some kind of aluminum coated wood panel that has a grove for pex, & is installed under the sheet rock, or a modern version of the cast iron radiator, or something else.
Wow, what a lack of snow in the mountains this year, quite the change from last year. Now I'm really concerned about Fire this summer. Hope things are well in your world.
Thank You for the info:
