Steam

@ October 18, 2012 7:39 PM in Condensate accumulator

That looks like it was made by Kellog Mackay. That open pipe may have gone to a mercury pot as an air seal. Do you have any more pictures?

Furnace

@ October 18, 2012 7:31 PM in Short cycling during cool down

Downflow furnaces are notorious for temperature related problems. Sounds like the heat exchanger is still warm enough to turn the fan on through the limit switch.

It could also be a bad limit. They tend to wear out after being overused in short cycle situations.

NY

@ October 14, 2012 9:54 PM in Looking for plumber in Nassau County

I'm in central, eastern NJ. I do work in your area. Follow my link and give me a call, or email.

Rad

@ October 14, 2012 6:26 AM in Gurgling / water build up/ spitting air valve

Have you checked the riser size against the connected radiator load? You may be venting TOO fast. Frustrating, right? Venting too fast could lead to excess condensation building up too quickly.

I'm in NJ, too. I'd be happy to help with anything you need.

I definitely think you need to assess the venting on all of the radiators, and possibly the whole system. It sounds like a total balance issue.

Tstat

@ October 13, 2012 11:23 PM in WM SGO-3 short cycling even when t-stat is satisfied!

The tstat goes to R and W without a jumper.

Rads

@ October 13, 2012 10:57 PM in Banging steam pipes need help

Can you check if the rads are pitched towards the trap? Any pictures?

When you turn the valves off, is it when the radiator is already hot?

Boiler

@ October 13, 2012 10:09 PM in WM SGO-3 short cycling even when t-stat is satisfied!

Disconnect the thermostat. See if it still happens.

Boiler

@ October 13, 2012 10:05 PM in Worth upgrading?

I'm in NJ, too, if you ever need onsite help. We do a lot of boiler work near you.

A mod/con will always be an immediate upgrade. You'll be going from 83% to 98% efficient with any good high end boiler. Plus the additional benefit of the oudoor reset. The ROI depends on the size of the boiler, and projected savings.

At the very least, I would highly recommend adding an outdoor reset to your current boiler for a quick and easy 10-20% reduction in fuel usage.

Steam

@ October 13, 2012 5:44 PM in Banging steam pipes need help

Have you had this problem in the past? Did it just start this year? Could be bad traps, or sagging pipes. If it just started his year, odds are that some traps went bad.

Loop

@ October 13, 2012 5:40 PM in Hot Water Loop to Steam Boiler

Don't use that plumber!! Call a heating professional. Where are you located?

You need a bypass loop, at least, to maintain proper temperature in the pumped loop. A heat exchanger is not necessary on all applications.

Vent

@ October 13, 2012 7:47 AM in DOES ANYONE NEED ONE OF THESE?

It does look similar to a Trane vent, except the female fitting instead of a male thread on the bottom, and the hex nut on top.

CSST

@ October 13, 2012 7:22 AM in low inlet gas pressure

1/2" of CSST gas pipe is only good for 55,000 BTUH. You need at least a 3/4" line, but I would use 1".

Vent

@ October 13, 2012 7:00 AM in DOES ANYONE NEED ONE OF THESE?

Nice. I would never use that on a job, but it would look nice in my office. Hmmm. Gotta send this link to my wife.

Steam

@ October 13, 2012 6:57 AM in Tenant needs heat

Where are you located? We may know a local steam guy who can help,

Wrapping the pipes will only help a little bit. Do the radiators have air vents? They could go bad.

Zones

@ October 12, 2012 8:21 PM in Taco pumps and zone valves wiring with SR503 relay

Treat the zone valve end switches as the "thermostat" at the zone board. You can pigtail them together on one terminal for the pump. You then need a separate transformer to power the valves and thermostat circuit.

Heat

@ October 12, 2012 12:44 PM in Here Comes the Heating Season!

11. When you boil water for pasta on the stove, you grab a chair, a stop watch, and a notebook.

Filter

@ October 12, 2012 9:47 AM in Heat Pump

I've had a helper install the FD backwards on a straight AC system. Never had a problem.

CA

@ October 12, 2012 9:46 AM in Analyze my combustion analysis

The high stack temp could also be a slightly high draft as well. You can see the excess air go down as the temp goes down. With a draft hood, there is no way to control that. Did you take a draft reading right out of the boiler?

Heating man

10. When driving on a major highway, the next exit is an-inch-and-a-quarter miles away.

Gas

@ October 11, 2012 10:39 PM in Reducing gas supply to oversized steam boiler????

Lowering, or derating, a gas appliance is both innefficient and unsafe. That method is largely regarded as a terrible idea. The contractor has a responsibility to correctly size and install the boiler.
