If the wall

@ February 12, 2008 10:28 PM in Replacing Baseboard without removing the heating element

material is drywall or plaster and the baseboard is screwed in place you are lucky. If it is nailed it is a pain to pull the nails. I have found it easier to use the pin from a slantfin nailing tool to drive the nails through the back of the baseboard into the wall. You could use a piece of steel rod 3/8" in dia..

what model economite you have. There was another model that didn't use a conventional gas valve. The gas valve was operated by a centrifugal mechanism in the blower, no electricity. To light the pilot you will see a small metal toggle switch on the side of the control box, it's spring loaded in the off position. When you hold the switch down you energize a small coil of nicrome wire that is next to the pilot.

Wow, to cut and paste that URL I had to replace the bearings in the mouse twice. The Lambda technology sounds like a good deal. I think Saab used that idea to control their fuel injection back in the late 80's. You sure are a busy guy. Imagine my surprise when I saw a hover-craft with your name on it in Pueblo,CO.

The best I have found is Swaglock "Silver Goop" you don't want to know what it cost. They sell it in one ounce tubes. Besides having SS dies we found it helpful to put a variac speed control on the pipe machine to slow it down. A cheap alternative is teflon tape and Johnson's Baby shampoo.


@ February 4, 2008 12:38 AM in the math of circulators

Mike, I am not real sharp with math however I count at least 27 different combinations of your 31' head pump and the 5 zone pumps. You have at least 27 different operating points on the system curve and 27 different flow rates. Each of the pumps will effect the performance of all the rest of the pumps. I wouldn't want to try to calculate the operating heads and flow rates for all the pumps at all 27 conditions. bob

If my memory is correct, in the 50's they were T-86.

I think that the built in analyzers could create a lot of work for burner professionals. The government could notify the owner that his burner was out of spec and that they have X amount of time to get it repaired.

Simple Solution

A combustion analyzer is just an oxygen sensor and a microchip processor. Large burners have them built in. Oxytrim. Why not mandate that they are built in to every burner. They could be linked to the government by phone lines or satellite. bob

I was

@ November 9, 2007 12:53 PM in Pump Motors - question on saving energy

taught to always try and keep minimum velocity above 2FT/sec to keep air entrained. B&G even recommends reducing pipe size to increase velocity when flow is verticle-down. It seems like the micro-processor and the petrochemical industries have eliminated the need for engineering and piping skills. Jest git yerself a modcon a VFD pump and sling a roll a PEX on yer shoulder an go fer it. It'll all self adjust. bob

@ October 27, 2007 12:09 AM in Foil behind baseboard radiators???

in my neck of the woods it is standard procedure to install foil faced kraft paper behind cast iron baseboard. It accomplishes three things. It reflects heat into the room, it reduces heat loss by retarding heat flow into the cold outside wall,and we always ran the foil higher than the baseboard and folded it down on top of the baseboard before the trim carpenter installed his molding. After the molding is installed you trim the excess. This prevents streaking up the wall.

Like Ken says

@ October 24, 2007 7:05 PM in What happens if circulator pumps fails?

there are a LOT of variables. If your only concern is the pump you can pipe two pumps in parallel with check valves. Depending on how your system is controled you can rig up a flow switch and maybe a relay to disconnect pump 1 and start pump 2 if you loose flow. bob
