Is that something I should be able to figure out by digging through the manuals or should I find someone proficient with Lochinvar boilers? Keep in mind this is my first boiler.

According to the heating system summary provided by the company that did the pex tube layout the total heating load is about 24,000 btu/hr. The boiler does have a temperature sensor fastened to the copper output pipe. I don't know what the boiler output really is but I've attached a sequence...

Last week I lowered the setpoint from 130 to 110F and within a couple of days I had more condensate than was produced in the previous five weeks. So I think those who suggested it was running too hot and not in condensing mode are correct. But when I watched it run it seems to cycle often. It...

Those round white balls are part of the neutralizer to transform the acidic condensate to a neutral pH. Others in this thread have said that neutralizing the condensate is required by code in most places. Yours looks very much like the Rinnai neutralizer I installed on my condensate line.

So I spoke with the installer today and he said the condensate will come. The boiler isn't running during the day right now because of passive solar and the well-insulated SIPs. And he said there will be more condensate with increased humidity. The setpoint I saw may not be the actual which...

The Lochinvar WHB085 boiler is only being used to heat the garage's slab, no domestic hot water. I didn't do any of the boiler's setup so I don't know the flow rates. There is a system pump for the slab and a boiler pump for the primary loop. It's a well-insulated structure built with 8" SIP...

That makes more sense. The company that did the pex tube layout used CAD software. I checked their software's output and it shows a floor temperature of 79 degrees requiring a water temperature of 118 degrees for an embedded slab with outside temperature of 10 below. Hopefully, I'll hear from...

I didn't do any of the setup for the Lochinvar boiler so I have a call in to the installer. The garage slab has four tube loops but it is configured as a single zone. I found a setpoint screen on the boiler and it shows SH1 (space heat 1) at 130 degrees, SH2 and SH3 at 125 degrees, and DHW at...

I'll check the documentation or call the technician to check on that.

So I installed a neutralizer, ran the condensate into a 30 gallon drum, mounted a pump on the wall with a nice switch. All I have to do is drop a hose out the window, prime the pump, and flip the switch to empty the drum. But where's the condensate? The boiler installer told me I'd probably...

I do plan to mount the pump and make emptying the drum simple. But this winter will be a trial so I won't get too carried away just yet. I'm still thinking about a more permanent drain solution. I've done it in three crawl spaces so I know I can dig down through five to six feet of clay and...

Long story but I thought I would be doing the boiler install myself until I read the instructions and learned the warranty would be void if not installed by a licensed tech. I had no heat last winter because I couldn't find anyone to sell and install a boiler. Too many trophy homes being built...

There is no drain to freeze. That's my problem. I didn't have the foresight to learn about condensing boilers before I poured my slab. I have no drains at all. For now, my plan is to run the condensate through the neutralizer into a 30 gallon drum. Once a week I'll open a back window...

Interesting. So the guy from MN is in violation? Is it a code violation if there is no one to enforce the code? Although I try to build to code, my county has no building inspectors. When I built my house the only inspection was for the septic tank and leach field. No inspections for the...

Good to know. I am reluctant to try to automatically pump it through the wall. A guy from MN in this thread shows it working for him (scroll down for pictures). But I'm not convinced that will work at 20 to 40 below.

This sounds like a good solution. The bottom of the wall mounted boiler is six feet above the floor so I have the room. Since I'm reluctant to use an automatic sump pump initially, I can still use a transfer pump I turn on with a hose out the window. Later, I can use a sump pump with...

The boiler is wall mounted and its bottom is six feet above the floor. I can't just run a drain line out the wall because it will freeze. That's why I want to let it drain into a sump and then pump it out with infrequent bursts either automatically or when I turn a pump on. If I stick a hose...

I couldn’t find any local contractors to build my dream garage last year so I had to go it alone. I went with hydronic heating in the slab and from what I read in these forums I chose a propane boiler over a water heater. But I made that decision after the slab was poured when I didn’t know...

Nicely done. They do look good painted.

Battens or even faux beams over the roof panel seems is a good possibility. If I could do all the priming and painting of the OSB while the roof panels are still on the ground that would be slick. I also read that this company marks all the electrical chases on the interior OSB with blue...
