@ June 20, 2014 11:28 AM in Oil to Gas conversionwhat kind of excess air numbers the Midco LNB is producing. We see near-perfect combustion from that type of burner in other applications.
@ June 20, 2014 11:16 AM in Aquatherm pipingI'll repeat one of them here:
is our preferred choice for sizes over 1" nominal for both hydronic
heat/cooling and DHW. If the largest pipe in the job is 1", we specify
ProPEX for everything. On larger jobs, it's still easier to use PEX for
the small stuff and transition around ~9 GPM to Aquatherm. The
flexibility and cost of saddle welding are tough to beat. Watch out for
the transition fittings -- over 1" they get spendy fast.
I'll shoot you an email with my cell number if you want more details.
@ June 19, 2014 8:56 PM in Ductless Split Head PlacementIf so, I'd probably opt for a four-way cassette.
@ June 18, 2014 3:54 PM in concentric termination relative to dryer ventare a solution of last resort for me. A wall intake with a roof vent is the go-to solution whenever possible.
@ June 18, 2014 3:51 PM in Hot RadiatorsThanks -- we'll give it a shot. Gave up on the magic silver stuff years ago and have been using the tiny tube of something Intel sent way back when.
@ June 18, 2014 11:58 AM in Made in AmericaThink I'll stock up on those next time we run out.
@ June 18, 2014 10:58 AM in Hot RadiatorsGot a brand you like? I'm looking for some and the computer type is $$pendy.
@ June 16, 2014 3:37 PM in Volts x Amps x Power Factor = what?Power companies meter kVA and kVAR on medium to large commercial and industrial accounts.
@ June 13, 2014 9:19 PM in TRV, with remote sensor or no?is proportional zone valves paired with modern controls. Standard practice for DDC jobs, but unfortunately not available for off-the shelf residential and light commercial applications, at least in North America -- yet.

@ June 13, 2014 8:50 PM in Steam-Heated Hotel!> The manager I talked to, one of the family that owns the hotel, is not
opposed to restoring the system. He says he will have us come up later
this year, and this time we'll have full access.
> I hope we got to this in time.
So do we!
@ June 13, 2014 8:42 PM in Returns covered by the Sheetrockwill usually find the sheetmetal if it is close to the drywall.
@ June 11, 2014 5:01 PM in Presidentbut if they are crossways to the joists, you might be able to tuck the risers into the joist space and then drop down for the header.
I'd seriously consider a slab cut and a well, at least for the larger boiler.
@ June 11, 2014 4:47 PM in Typical venting for high-efficiency wall-hung boilers?I would size it, design it, and then get a letter from the Mechanical Bureau accepting the proposed phased construction approach. Then pull a permit, install the vent and probably the NG line for the boiler, and have it all inspected.
@ June 11, 2014 4:40 PM in Volts x Amps x Power Factor = what?reads true wattage, and properly accounts for power factor.
The separate demand load (kVA) and reactive load (kVAR) charges on a commercial account cover the utility's butt if you are doing bad things to the grid.
@ June 10, 2014 7:16 PM in Volts x Amps x Power Factor = what?Not quite sure what that means, but more importantly what are you trying to calculate? Conductor size? OCPD size?
@ June 10, 2014 10:58 AM in Sizing New Gas Steam BoilerCan't find a spec sheet on the Bryant, but the IOM is online. 262 MBH NG firing rate, 671 square feet. I know Joe has been doing a lot of 2-stage firing lately and look forward to hearing more.
@ June 9, 2014 5:16 PM in Sizing New Gas Steam BoilerJust curious, and want to compare square feet so I can wrap my head around this.
@ June 9, 2014 5:08 PM in concentric termination relative to dryer ventEvery I & O manual I have seen is quite clear on the specifics.
@ June 9, 2014 10:05 AM in Sizing New Gas Steam Boilerfor those of us who got lost along the way. Which boiler did Joe recommend, and do you still have 325 square feet of EDR to heat?
@ June 9, 2014 12:13 AM in Phone Call or Email From Boiler Alarm ContactsAssuming you don't have any existing infrastructure, http://vikingelectronics.com/products/view_product.php?pid=418 might work.
@ June 8, 2014 10:48 AM in Sizing New Gas Steam Boileris already included in the boilers square foot rating.
