@ November 4, 2012 4:21 PM in Starting up steam Boiler w/out electricity?You need to know the power requirements for you boiler before you buy anything. Most low cost inverters these days are relatively efficient at converting DC to AC, but many have a relatively high idle current. Translation: They may be 97% efficient when delivering 500 Watts, but less than 50% efficient when delivering only 40 Watts. You need enough batteries to run the system while discharging them 70% or less. We can help you design this if you can provide the load info.
@ November 4, 2012 3:30 PM in Peerless Purefire wil not run on generator powerGood point (yikes.)
Interlocking breakers on the main panel is usually cheaper and will do the job for occasional outages. We try arrange this whenever we can for residential and light commercial jobs. http://www.interlockkit.com/ has a lot of good info - parts are available from any electric supply, but few actually stock them.
@ November 4, 2012 3:16 PM in Peerless Purefire wil not run on generator powerMost UPSes that cost under $5k produce so-called modified sinewave outputs that should properly be referred to as a modified squarewave. This does not present issues for most switch-mode power supplies (like you see in modern electronics) but can wreak havoc with low cost linear designs that lack proper input filtering.
Have you tried using another genset?
@ November 4, 2012 3:06 PM in Peerless Purefire wil not run on generator powerGenerators ship with a bond between neutral and ground, and standard transfer switches assume this. There are special cases where a separate, switched neutral is needed -- but they are not particularly common.
I'm still curious what Peerless has advised him to do. Connecting green and white wires together inside any building is a VERY BAD IDEA.
@ November 4, 2012 12:30 PM in Peerless Purefire wil not run on generator powerAre they actually advising you to connect the neutral (white) wire to the case of the boiler?
@ November 4, 2012 12:13 PM in Peerless Purefire wil not run on generator powerA power conditioner will often allow the boiler controls to function when running on a genset. The glorified power strips sold in computer and hifi departments will not work. Cleaning up a low frequency sine wave requires many pounds of iron and copper - small ones (under 200W) weigh in at about 5 pounds -- it takes about 80 pounds to handle a fully loaded 20A circuit.
@ November 4, 2012 12:01 PM in starting up gas boiler with portable generator or battery?You need a clamp-on ammeter with a peak hold feature so you can determine your real requirements.
@ November 3, 2012 9:09 PM in Electric Baseboard question, for heating second floor of garage.is in the floor of the garage? Is it hydronic or electric?
@ November 3, 2012 1:26 PM in new boilersPretty sure the neutralization requirement here is actually a state modification to the UMC. Regardless, condensate and cast iron do NOT mix, so you're on the right track. We use http://axiomind.sasktelwebhosting.com/CondensateNeutralizers.php but there are plenty of options.

@ November 2, 2012 12:35 PM in analyzerI know, they've made some junk in the past. The new Eagle X stuff is in a different league, and they're putting their money where their mouth is with a five year warranty covering calibration and sensors.
@ November 2, 2012 11:11 AM in Recommend a circulator control?What kind of boiler and zone controls?
@ November 1, 2012 8:59 PM in Rinsing the boilerBased mostly on what I've read here, and with previous Rhomar experience, I'm going to try 9150 on a system that has about a century's worth of crud in it.
@ November 1, 2012 8:36 PM in Rinsing the boilerSaw the copper at the end -- must have been oxidation on the rest of it. Flare fittings?
@ November 1, 2012 7:31 PM in Rinsing the boilerVery nice. I thought you gave some details on the wand construction a few months back but I don't seem able to locate them. Looks like it may be steel pipe (with some kind of straight thread fittings)?
@ November 1, 2012 6:25 PM in Who has the best residential gas steam boilerAre not made by the boiler manufacturers, but by third parties (Carlin, Midco, Riello, etc.)
I just looked into this about a month ago for a customer. Smith used to ship the G8 / EZ-Gas combo but no longer provides it as a prepackaged SKU. No warranty issues from either manufacturer with the combo, but they do need to be purchased separately by the installer.
@ November 1, 2012 3:18 PM in Adding a fan coil to a hydronic systemReally does need a bit of math. Do you have any data on the reheat coil?
@ November 1, 2012 12:38 PM in Please help stuck in disaster zonePlease tell me you understand the implications of this.
@ November 1, 2012 10:29 AM in Rinnai vs. Burnham Alpine 95% boilerIf it happens to be a Helix VLT, it has a fire-tube HX and I'd give that serious consideration.
@ November 1, 2012 12:43 AM in timerI prefer occupancy-based controls of residential recirc pumps, but existing commercial buildings can get rather complex. If you do use a timer, you might try one that's sunrise/sunset aware, e.g. http://www.aubetech.com/search/index.php?recherche=Switches&recherche2=5
