Re: Why is my hotwater baseboard heat not very hot?
bb problems eh?
There are many reasons that would cause your problems. Let's give it a look...........Your aquastat [that is the devise that controls the temperature of the water in your boiler] should be set at 180*; Do you have a circulator for those two heating zones? Is it working? When the superstore was installed, did anyone make sure the boiler is capable of providing both heat and hot water at the same time? Those SuperStors are a great product, but ya gotta give 'em the BTU's. Maybe ya oughtta try shutting down the SS to see if the heat comes up. I'm going to assume you had the heat on this season already. Did it work OK before? BUT was the outside temp. the same. Normally, heating is sized to raise the temperature about 70* higher than the outside temp, so at 11* outside, you should be able to get about 80* inside. ONLY IF the BB was sized correctly along with the boiler and the SS

Re: Beckett AFG Efficiency Testing + Boiler sooting issue
Oil is lighter than water so the water is on the bottom obviously. Before the EPA got involved we would have commercial accounts with underground tanks in parking lots. After a snow plow would rip the flush fill cap and the snow melted we would get no heat calls because of water in the tank.
Take a half inch pipe and cut the end on a 45 and drop it down the tank fill pipe and pump the water out of the bottom of the tank.....and down a storm drain
...............can't do that anymore. Put some oil treatment in the tank.
Had one at a big school once. The fill pipe was in the sidewalk in the back of the school. There was a manhole cover flush with the sidewalk and a 4" fill pipe with a threaded cap under the manhole cover. The driver was delivering a load of oil in a snowstorm. He pulled off the manhole cover and the cap. When he was done he just put the manhole cover on after losing the cap in the snow. When the snow melted we had 3000 gallons of water pumped out of a 10,000 gallon tank. The tank was 16' below the sidewalk in the old coal bin. It was very slow pumping that out. Had a guy with a septic tank truck pump it.

Re: Beckett AFG Efficiency Testing + Boiler sooting issue
Update: the tech from Joyce Cooling & Heating came out this morning. Completely stumped. We talked through everything that's happened, he witnessed the pulsation, made some adjustments to the air to get the combustion numbers a bit better. He was able to get the following numbers at 20° on the air shutter:
He also pulled a 2000 Ohm reading on the cad cell, which he said was pretty high, but he didn't believe it warranted replacement.
Nice guy, didn't charge me, said he would raise the case at his service meeting tomorrow morning to see if anyone else has ideas.
-
- 379.5 F = Temp Stack
- 4.3% = Oxygen
- 7 ppm = CO
- 12.47% = CO2
- 84.7% = Efficiency gross
- 25.9% = Excess Air
- -0.029 in-H20 Draft

Re: oil furnace sooting extensively
That is another way to do it. Regular pump with a valve kit.
I just like the Clean Cut Pump. It is easy.

Re: Peerless NV 22 Garage Heater - help
I am not sure what is on the other end of that capillary tube but it may be an electrical switch that is activated by the temperature sensed by that probe (copper tube). My educated guess would be that the probe you are holding in your hand has fallen off of a bracket that holds it close to the heat exchanger so it senses the heat. Look for a bracket that might place that probe in a position as illustrated in this picture.
Thank you.
Sitting at home, when it is minus 34 C (Damn cold F) my bare feet on the tile floor, am feeling very grateful to the people here.
Eight or nine years ago, started hanging out here, learning & studying space heating. The knowledge gained and assistance/advice is directly responsible for giving us a very comfortable home. Learned how to do a load calc, learned about insulation and hydronics, and some interesting work processes along the way.
Thank you so much.

Re: Replacing old style expansion tank.
Based on my personal experience,
and knowing that your cast iron rads will hold a lot more water than a baseboard system, if the chart calls for a #60 tank, I would go with a #60. I have had a couple of cases where the chart said 30, but it was border line 30 or 60, and we had to go back and put in the 60 to keep from popping the relief. Plus the #60 will give you a little extra room for error as the air side slowly looses pressure from year to year.

Re: Inquiry sent to Xylem today - Update with new circ (Grundfoss Alpha)
At 120F the valve starts modulates and you can see bypass flow start dropping, system flow starts moving. At 140F bypass is 100% closed, all system flow.
I did some adjusting and got almost 13 gpm, so over 6 fps
I have a short loop, so this happens quickly. Pump noise, boiler ramping up noise, but nothing I can hear in the valve?
I'll still try a delta P circ to see how flow responds as the valve modulates. But as one port closes the opposite opens that amount, so there is no increase in delta P I suspect.
