I will post again

@ April 9, 2014 6:58 AM in LAARS Endurance problem

I posted this in your other thread

Start by checking the internal zone valve if it isnt shutting all the way it will allow heat to pass by all the time depending on how your boiler is piped. It will also not open on your second boiler to allow heat out, but there are many possibilities for lack of heat.

R- Value

@ April 8, 2014 4:01 PM in R- Value

Hey Guys

Looked at a job today that has 12" thick brick outside walls. They are double brick walls with an older board insulation in between the two. Anyone know if the Uponor program will know what to rate that style outside wall for R value? I haven't run into this before, it's very similar to a school building it has big wall mounted convectors feed with 1" copper and lots of windows!!

Lead Free

@ April 8, 2014 3:55 PM in New Lead Free ball valves

One thing I noticed here in Vt where they changed to lead free a couple years back, was if I wasn't using a specific Flux the solder wouldn't run the way it would with the old brass valves. I switched to Utility Flux and it's been much better since, Im sure there are quite a few out there that would work well.


@ April 7, 2014 6:56 AM in Anyone familiar with "Heat Load Pro" software?

After reading this thread I see I cant get Heatload on an Ipad so I am willing to purchase a windows based tablet, like a surface pro 2. Anyone know if this will work properly? I already own an Ipad 3 and really want a tablet that can be mobile with me and run Heatload or similar program, any suggestions?

Zone Valve

@ April 6, 2014 12:07 PM in LAARS Endurance problem

In the Laars there is a Honeywell zone valve that opens and closes on heat demand. At times those go bad and allow the heat to go through all the time slowly or fail the other way and dont open allowing no heat I would check there first.


@ March 28, 2014 6:16 AM in My first ALPHA pump

Thats great news, I really like the concept of the pump and hope it performs in real world applications with longevity, but I fear it will only do 3 to 5 years and fail. Hears to me being wrong!!


@ March 24, 2014 6:43 AM in My first ALPHA pump


I have installed 2 taco delta T pumps and I can't do anymore until they stop using cheap components that don't buzz. The one customer complained from day one and within a week I went and changed it out. The other is very old and cant really hear, so I think I am safe. IMO needs a little more engineering, I like the idea and the price for what it can do but it's not a perfect match for everything.

Sorry, to get back to the thread. The directions ask you to put the pump on high at first, I never have but maybe that will get turning, otherwise maybe you have a dud.

Small town feel

@ March 19, 2014 5:49 AM in I'm working out in the shop today


I as well like to grab a coffee and tell hyperbole filled stories of human strengths I don't have but sometimes in business you need to break the mold. For instance, when I was first starting out I used only one wholesaler, they treated me ok and I felt loyalty to them was important, and I knew everyone and I felt good when I stopped in. After a while though I needed a charge account and they kept saying no, they are corporate and I didn't own anything of value for them to go after if I didn't pay. I got a little annoyed (maybe a lot) and I went down the road. Turns out the competitor had things I had never seen, nice stuff like Caleffi and Viessmann, they also did many more training classes, gave me an account up front, provided incentives for buying, and all in all gave twice as much support not to mention much better pricing! Turns out the first guy found out and wanted my wimpy 100K a year in sales back so he changed his ways gave me my account and lowered his prices because I saw the difference with the new guy.

Moral of the story is: I hear you on the internet sales, my preference is face to face over a hot coffee but if you jump ship on tubing and manifold stuff only maybe the lack of sales will force your wholesaler to bring it back or get creative and find ways to keep you happy. It worked for me. Who knows you may save a lot of money buying online, I don't know I never have had to do it.

Thanks for the answer

@ March 13, 2014 7:16 AM in Pumping away ? I must have something messed up! Help

For closing the thread and giving us the answer. It drives me crazy to read many, many posts and then no answer!!

Tough Choices

@ February 16, 2014 6:18 AM in Dodge promaster van

Sprinter: I've owned a 2003, a 2004 and currently a 2007. If I was to buy another one it would be a 2006 158" WB

If the Transit ever actually shows up I am going to have to seriously consider it. I love my diesel motors but due to emissions and how quickly they kill diesel motors I would probably go gas.

I have considered a truck with a box but they don't typically get the mileage or have the cargo space of a sprinter


@ February 15, 2014 7:05 AM in Dodge promaster van

I do believe at times its luck of the draw. I have had 3 sprinters and no major problems with any of them. I cant seem to find a van that can replace my sprinter. I have a ton of room, I can stand up in (im 6'2") I have 14' of cargo room to put in pipe. It gets 25mpg on the highway at 62mph in the summer, and it drives like a car.

Sadly though they are terribly expensive to maintain and when they break it takes a personal loan to fix but find me something today that can replace it? They are sorta like a Mod/Con in that way, you know they cost more upfront and much more efficient but when it breaks you wonder where the savings is, and you hope someone can fix it!!!


@ February 11, 2014 7:41 AM in Laars Endurance Boiler L.O. code

LO does mean Lock Out. It comes up from a variety of things. If it comes up immediately after hitting reset I would say it's more than likely a control or wiring problem. You can do an internet search for Laars Endurance Manual and walk thru the steps to find the fault.

My guess

@ February 5, 2014 6:20 AM in Baxi HT 380

The delivery driver is shutting off the tank while he fills. If this happens when the boiler is running it will lock out on attempts to fire.

Thats just a guess though. Sounds dumb but also make sure you have a good ground on the electrical supply, that can give random lockouts.

Good Question

@ February 2, 2014 8:28 AM in Dodge promaster van


I dont know the answer but I wanna add some questions to your post hoping someone will know:

1 How's the front wheel drive in the snow?
2 Whens the diesel option arriving?
3 How's it drive, like a E250 or like a sprinter? (big difference)

New Problem?

@ February 2, 2014 8:23 AM in Not getting enough heat.

Is this a new problem, in the past could you get the system to 75? Oh and IF that is a manual reset high limit then you need to set it a bit hotter than 195, it needs to be around 220.

@ February 1, 2014 7:36 AM in Is the cost of a mod-con worth it on hi-temp baseboard?


I hear what you are saying, my question is always: Does the modulation save enough to cover the sometimes frequent and expensive service calls or yearly maintenance?

I was curious if someone has crunched the numbers of fuel consumption of 87% bullet proof cast boiler and a 95% wall hung mod con on baseboard for a heating season? Factoring in upfront costs, LP or Nat difference (price, BTU), additional piping for modcons, and all the miscellaneous that go with them.

My opinion is modulation when sized right for the load should give you the payback even with high temp baseboard.

Hopefully someone who can give real world numbers chimes in as well.

and noisy

@ January 31, 2014 6:18 AM in Thinking of replacing existing pump for a Taco Bumble bee pump

The bumble bee is much louder than normal pumps. If thats a factor.


@ January 26, 2014 6:57 AM in New boiler, Insufficent heat

What size is the master bedroom, I know you stated how many btu's but how big is it? If possible how many loops feed it?

Isolation clips

@ January 9, 2014 7:29 AM in Could this the problem?

To know for sure if it is the lack of isolation clips, cut up a plastic container, perhaps a yogurt container or something like that into squares and put them into position.


@ December 30, 2013 7:31 PM in Warmboad Vs Thermalboard

According to the charts at 20btu per sqft warmboard is 90 and thermalboard is 98 Typically real world numbers and applications make a lot more sense to me. So my second question is has anyone done both and can testify to the numbers?

The noise I speak of is squeaking coming from the thermalboards on the subfloor. I am sure if it's done right its no problem just want to ask first.

Warmboad Vs Thermalboard

@ December 30, 2013 5:23 PM in Warmboad Vs Thermalboard

Hey all

If the bank is willing, I will be building my own house this spring. Of course I want to make good choices that I will not regret for years to come. One of them being to go warmboard or thermalboard. Thermalboard is half the price but twice the pain on installation but can be put in after all the interior rough in is done which is a bonus. So my question is has anyone used thermalboard? If so what kind of difference in water temperatures between them, I know Warmboard is the best possible choice, but if thermalboard gives the same water temps without noise while running then I can afford to get good hardwood floors.

A little off topic

@ December 28, 2013 7:42 AM in Modcon Heating Cycles Per Hour


This is a very intriguing thread. I am curious, if you are shooting for less on and off cycles (as we all are), what effect does the cycles for hot water usage have on a combi boiler? I would love to have all my boilers get to the point where they only fire 100 times a year its much better on any equipment. It seems to me that if a combi turns off and on 30 times a day for heat and hot water its going to shorten the life span by quite a bit. Any thoughts?
