We finally get a little cold spell to put our systems to the test. So how is everyone doing? After being in the single digits all day we went a little below zero last night in addition to a 15mph breeze. At last check we are up to +2*. I had to pull out of the pine I had been burning and switch over to some good stuff, oak, cherry. Filled her up at 5:30pm yesterday and today at 9:00am had a nice coal bed to start over with. House was 74 when I went to bed last night, set back to 71 at midnight then back up to 74 at 6am. That along with 1 bath and 2 hot showers, and keeping my garage 55* I have to say I am pretty happy. Hope everyone else is having similar results! :thumbup:

In Northern MN we had -25 last night and will probably hit a high of -7 today. This is my first year burning wood and am running a Hardy H5. Put a few extra logs in but other than that I have not noticed a big jump in usage. Days like this I am very pleased to be burning wood and not oil. I am seeing my wood pile shrink but that's ok. Stay warm everyone!
-
Oh yeah sure got cold it said -10 to 15 with wind chill last night sure glad I got the owb I am burning sycamore I put a few splits in yesterday at 2 pm before work and put 8 big splits in last night at 11. My furnace is running a lot but it doesn't matter lol. We keep ours on 73 and we are comfortable. I couldn't imagine electric bill if we didn't have it
-
I forgot to mention I live in central ohio and like you said I don't notice much more wood usage but my pile is slowly going away oh well over all burning since September 17 I have used roughly 6 cords using hardy h4
-
I really didnt ever imagine I'd be this excited about cold weather ;D
This is our first year too being soley on wood and its been fun to compare previous years data. My wife and girls are LOVING this heat and it makes me feel so good to not cringe and see dollar signs when the heater turns on. We now just wave to the Gas man as he drives by slowly :D
This weather sure has been aweful but I really wanted to see what this thing would do and how much I'd have to load it and I can say that I am very impressed. I do need to do more house Insulating to make it really sing I think. The wind just comes straight thru the walls :bash:.

Doing well here in ky as well. The little tiny xt was able to give me about 12 hours last night on a load of split oak. Temps here were around 5 degrees with windchills -15 to -20. Currently 13 degrees. Expected to head towards 0 tonight.
-
I live in NC near the Blue Ridge Mountains. It's been fairly nice here but just started dipping into the
20's this week. I haven't really noticed extra usage yet but I'm sure it will start as the temp stays
below 30.
I burn mostly oak/locust but do use pine to help get a few fires going.
Hope everyone stays warm!!!

Informed the propane delivery guy today, that he need not return until fall thanks. It will be in the - temps for the next few nights here in NH. Fifth season with the CB5036 and I do not miss the sound of my propane furnace. I also do not miss the bill.
-
Cooch - I live in NH too and isn't it nice NOT hearing the oil/propane furnace run? When I did heat with oil, I had to keep the house at 68 and not higher. As it was I was spending over $5,000.00/year for fuel oil. With the OWB, I keep my house at 70 degrees, 24/7 and heat my DHW with it. As far as I'm concerned my OWB has passed the test with flying colors. Granted it's my second year with it but with all new things, last year I experienced a lot of growing pains. Stay inside where it's warm. Roger

Northeast Pennsylvania and we had a hi of 18 and the low tonight is 8 . First year with the earth mountain man 500 and we're loving it! The house is set at 72 and it stays at 72 with a warm even consistent heat,also heating DHW and with no shortage. Best investment I made as a home owner and its already paying it's self off. I've been wanting this unit for a couple years now and thanks to this site and all the helpfull people involved the growing pains haven't been to bad. Still learning and thanks everyone for the good info. Stay warm everyone and happy burning!!!

North central ohio low of 6 today, 5 tomorrow -15 wind chill. Need more insulation in this old farm house, bumped up boiler temp to try and keep up.
-
-22 & -24 the last two nights here in Central MN. 73 degree inside :D Loaded a little more wood into firebox than usual so am still getting a 24 hour burn time. This is the kind of weather I oversized my OWF a little for. Bring it on!
-
24hr burn times easy with my burnrite out of mt pleasant mi. House is 70 constant and wife is a stay at home mom using hot water etc. Stove set at 170-180 using triple wrapped double tiled pex. Broeder pump properly bled out before during and after install on high speed with no issues.
-
Woke up this morning to 7 degrees and has been in the teens all day. Now it is headed back to 0 tonight but the good old stove keeps bringing the warmth to the house!!! Just put a couple extra pieces in the stove and head back inside to enjoy. Stay warm.

In Northeast PA here. My house was built in 1901 and really have only replacement windows. My house was a little chilly today being down in single digits. I had the thermostat set at 72 and it stayed between 63-66. Needless to say when it got a colder tonight I set it at 76 before I left and can't wait to see what it says when i get home. Anybody have any tips what I can do to help heat this old place up? It's base board water btw. Could start a fire in basement have a new stainless insert in chimney that I haven't used yet but I hate dealing with two fires.
-
I can't believe all you guys say you aren't using more wood. Same kind of weather here in eastern WV. And mine is using more wood at a faster rate. Last night I loaded my CB 5036 with the biggest pieces I could lift, as much as I could get in. This am there was a flat bed of coals and the water temp was dropping below the 169 set point with the damper open. I've got huge rr tie size pieces inthere tonight. Loaded it at dark and went out at 10pm to put a couple more pieces in. Hope it last thru the night. Therm is set at 67 at night and during the day...69-70in evening.
-
I use railroad ties also and nothing else (untreated) of course. I fill mine up about a solid 2 times a day during cold spells like this. Whens its 25+ degrees out I load 1-2 times a day and house temp is usually right around 70. I guess the woodstove can't keep up with a 10 degree difference in my house. I think I loss allot of my heat threw all the copper piping in the house though. I have been considering wrapping them to see if that helps.

What kind pf underground pipe do you have?
-
Honestly I don't know. This was my grandparents house and the unit is a 2004ish. They had it installed in 2007. All I can tell you just from me clansing at it is that it is about a 1" diameter white flexable piping LOL if that helps. Im still learing these things and all the parts. I'm the type of person that I want to try everything to save anything.
-
Yea.. The underground pipe is very very important
Hopefully you don't look down and see someone has shoved some pipe through schedule 40
-
I wish I could compair what I have by pictures to others piping. Like I said Im not sure what I have. The stove is about 15ft from house on concrete. The white piping goes down into a larger green pipe and into the house. I would like to have this changed but without knowing what I already have its a bit difficult.
-
Yep. Makes it tough
-
Going to start a new thread and see if I can get some pictures and better explain what I have and ask for some opinions to better what I have.
-
Sounds like u have what isnt good, but ur only going 15ft
So it could be much much worse lol

Having the same issues as you 1860's house hot water baseboard, set at 68-70 staying at 65-66 for the most part. I bumped my boiler temp up to 190 and restricted some on the zones going to rooms we were not using and that helped some. My main problem in the rate the house is using heat, the old oil burner can't keep up either need to get more than 3in of insulation in the attic, mostly single story house.

Black BTU's burning during the cold snap. Really well seasoned wood, better known as Coal baby! 24 hour burns with the 325G. Mixing bit coal and wood. House is at 75 when were home 68 when we go to work. Fill her up in the morning before my shower. Lows in the back woods of southern Ohio around 4 with -15 wind chill. Highs around 10 to 15. Heating 3600 SQ/FT hillside ranch, circa 1970.

Im using more wood. My problem is that I work 12 hr shifts and its just too much during these cold snaps. This is my first years with the restrictor in the pipe and the baffle inside the fire box. It did go thought the night last night on 3/4 full fire box.I was home last night and could check it. Today I filled it at 4 pm and wont see it again till 530 am. Ill post my findings.
-
I even turned my pump on low speed so my furnace humidifier can run longer but that didn't help. I simply have a efficient stove etc IDK.
-
Serious cold in the forecast for tonight 32 degrees below. Stove works pretty hard in this weather my biggest concern is that the blower is noisy when it gets seriously cold.

ok. Night before last it got to -14. I was gone 15 hours. had a nice bed of coals but the temp was at 145. Still better than I expected. Today it was about -5, but with 15 +mph winds and I was gone 15 hours. The temp was 165.It seems that the use of the restrictor plate, the baffle inside the furnace helped. And to top ot off this is the first year I have cut my wood at around 21 inches.Last 3 years I was cutting wood at 30 to 36 inches.
On both days the house was still at 68*. thats where I keep it always.Im building this house as I can. Out of pocket and have it 2/3 sided. Every little bit helps.
-
An you post pics of your baffle set up please so I can see how your furnace is different than mine
-
Hey walker
I been looking at the hardy site and dont see that baffle working.If you look at the CB site and click on the classic boiler you will see a baffle coming down from the top of the fire box. My baffle sits 2 inches closer to the door to direct the flame toward the water jacket and away from the stack. Totally different units I believe.
