Shaver Furnace / Re: dhw using stock coil
« on: November 08, 2012, 06:46:01 AM »
I believe the original pump was an Armstrong 30. When I bought my owb I upgraded the pump and they still sent me the Armstrong 30 which my installer put on the dhw. I will look at Menards today.
Also, can anyone post about how much they save per month on their electric bill by not using electric to heat their dhw.

I was having a similar issue with my home heating up slowly. I just had my plumber in and he bled the lines on my inside oil boiler with h20 baseboard. He said there was alittle air in my inside system. I will keep an eye on it the next few days.

Shaver Furnace / dhw using stock coil
« on: November 06, 2012, 06:03:20 PM »
hooked up dhw with stock coil on shaver. My installer (5yrs ago) used a armstrong cast iron pump to circulate. That pump corroded within 2yrs. To date I have not replaced this pump. Any suggestions on type of pump/circulator to get. I was told to get a stainless steel so I checked alternate heating and supply only one was $219.00

Makes sense RSI. Thanks for the suggestion.

I guess I expected too much and thought that this season would be different from the last four seasons with my Shaver. This season I started with all the modifications (i.e. ranco stat, solenoid with flapper, new door seal, and new seal on top of water tank, and even reinsulated the whole furnace).
The other day it was about 40 - 45 degrees my house was not calling for heat most of the day. I had the opportunity to observe my owb. When I ran the pump 24/7 the owb would cycle about every 35 to 40 minutes (personally I thought that was too many times given the weather and reinsulated owb). So with that, I changed the pump to run when my house would call for heat. Basically the furnace just sat there and idled. Now, my tstat is set to turn off at 179 which it did, however, I checked the owb 45 minutes to an hour later to find my water temp was 200 degrees. Last year my knowledge of the furnace told me I had an air leak. This I year believe the furnace is air tight and thought that maybe the furnace would have continued to heat an additional ten degrees before cooling down.
There is no smoke leaking out ash door or firebox door during the burn cycle to tell me there is an air leak. In fact, when I opened the door when the water temp was 200 degrees, there was no flame at all so I don't know how it was even heating the water.
My fear is that when I'm at work during the days when it is 40 degrees I will risk boil over. Maybe I should've waited before I turned on my pump to see how hot it would really get.
As a rule of thumb it seems harder to burn an owb durning moderate temps.
I guess I could also get a programmable t stat for my garage and set it to heat different parts of the day to pull heat of the furnace.
Can anyone tell me what I'm doing wrong or give suggestions?

According to alternated heating supply, the 1tdp7 has an rectangle outlet 3.25 x 2 3/16. Existing blower has 2 1/8 inch round outlet.

It looks like a nice blower but does not appear that the 1tdp7 will fit on a Shaver OWB. It there an adapter?

Electronics / Dayton Blower
« on: November 04, 2012, 07:40:55 PM »
Might be time to replace my dayton blower. I went out to fill furnace for the evening and noticed that the blower flap was up but the fan was not spinning. I tapped the fins inside the blower and it started working properly. I just replaced this blower last year. Should I try to clean the fins or just order a new blower at this point. I was thinking of ordering a 75 cfm blower. My current blower is a Dayton 1tdn7 (cfm) and the new one is a Dayton 1tdp3. They both have the same outlet diameter so they should interchange with no problem. Any thoughts out there?

« on: November 01, 2012, 07:29:51 PM »what kind of ir gun did you buy. i bought a cheap one (30.00) at home depot and couldn't get consistant readings.
It's a Extech from Lowes for $56. Not the one I originally went to purchase but seems accurate. I measured my arm temp and it was 98.4. For some reason it can't read accurately thru copper or stainless steel but can read thru pex and galvanized steel. I most likely will return it.

Sorry trz. I thought this was the best thread to post on with my issues.
Anyhow, I switched back to the inside furnace and cranked house temp up to 74 degrees. At 6:40 this evening the actual temp in house was 70 degrees and now at 7:18 the temp is 71. Something is not right. I'm thinking that my taco pump on the inside furnace is pooping out or somehow air got in the inside system. Not really sure at this point what is going on.
I purchased an infared gun and had some fun with it. Not losing as much underground temp as I thought. Temp. at owb 164 temp right when it comes inside 161. I also measured at supply line to baseboard heater it read 175 and the return back to inside furnace read 168.
Any additional thoughts out there would be nice.

First year I had my furnace it was open to the elements. Second year had 16 x 20 pole building built. Much nicer being under roof and out of the wind, rain, and snow. I have several rows of stacked dry wood within arms reach. The only minor down side I have is that smoke can build up as I am loading and cleaning the furnace.

General Outdoor Furnace Discussion / Re: furnace install near woods
« on: November 01, 2012, 08:10:39 AM »
My furnace sits about 10 yards from the woods (mostly pine) and has no cap or spark arrestor. I have not seen a spark come out of the flue in five years. The worst thing is the circulation of the wind. Most of the time the smoke is blown into the woods but occasionally it will blow back towards my house.

I started my furnace this past Sunday before Hurricane Sandy came. A day later the power went out. It is entirely possible that my line took water as it has been very dry as of late and Sandy dumped about 3 inches of rain in a short period of time.
On the other hand It may not be a sudden problem just the difference with the modified furnace that i am running this season.
Last season I had a strap on aqua stat (on supply line) that I don't believe was very accurate. For all i know my owb temp could have been running at 190 all season. This season I put a dry well in with the ranco digital.
I like the idea of running the furnace at 160 and most of my friends in the area run their furnace at 160. The more i read on this forum it is better to run at 180. I've been running this season at 170 but may have to increase to 180. Trial and error sucks but learning is not a bad thing either.
I will also look for a thermal gun then I should be able to see how much temp I am losing by checking the supply and return lines at the back of the furnace.

First season with modified shaver 250. My ranco reads 172 degrees and the inside furnace temp gauge reads 152 and my house seems to be taking an abnormally long time to heat. I guess it is possible but hard to imagine losing 20 degrees in a 70 foot run with my lines buried 40 inches. My lines are also insulated but I believe my schedule 40 conduit has a crack in it somewhere. I am also wondering if my heat exchanger could be causing the problem. Any thoughts.
Last season I did not have an accurate aqua stat to tell me the owb temp. only that my inside furnace consistently read b/w 160 and 170 degrees and the house heated up rather quickly. Other than the obvious, is there that much difference b/w 160 and 152 degrees when heating a house.
I also need to get a hold of a thermal gun
