Title: My New and improved H2
Post by: Bull on October 05, 2011, 06:39:25 PM
As I posted in another thread I did an extreme make over on my H2. I removed the skin and the 1.5 insulation and replaced it with 9 inches of iso and new metal to match my garage. I will try to post some pics.

Looks much better, Hardy should hire you to design their furnaces.  :)

LOL Thanks, I am sure that the added insulation will help in saving some wood. I also re insulated the house.

Curious to know how much that new insulation helps this winter.  I have wanted something more for my H2 but have not done anything.  Keep us informed please.

It has been so mild around here so far this year that I am trying some changes, I have turned my water down to 155 degrees with a 15 degree difference. So far the wood consumption is low with that change and the extra insulation.

I also doubled my insulation in the "off season".  I am not sure, so far, what difference it has made.  I should have a better idea in a couple of months or so.

I am also curious on how much your insulation helps? I have a H-4 and built a 14x14 shelter over it this summer to keep me out of the rain and a little bit of wood around it.As soon as i got it done i wanted the shelter bigger. May look at adding more insulation next year.

I know it is mild here in Indiana but I got a 15 hour burn last night and I only filled the stove about 2/3 with wood. This may not be to good to some but I really over work this little H2 so compared to last year so far this is good.

Sounds good!  Please keep us informed when the temps. fall.  I am really curious about your changes, because I have thought about changing mine for a couple years.
Where did you get the insulation and is it costly?  If I understand, you built a wood structure around the existing tank.  Is that right? If you have any other pics, that would be great! 
Thanks!

I put 3 layers of 3 inch iso around and on top of it, I am a commercial roofer and this is what we use on flat roofs . Not sure of the cost as this was extra material that they didn't want to haul back to the shop. I will look for some more pictures.

Has the new insulation helped the time between feedings?  I would like to modify mine at some point if it is worth it.  Weather hasn't been as cold as usual here.  Don't know where your weather is like and wheather you can notice a difference.

Yes it has made a difference, Given the same temp last year I would get an 8 hour burn and this year it is 12 hours. It may go a little better than that but it works out that I can feed it at 12 hour intervals. I do over work this little H2 but it does a great job. In warmer weather (35 to 50) it will go 18 hours now and last year it would only make it about 12.

Explain over working it for us if you would, my father in law is on his 4th season with his, heating 1600 sq ft shop, 1000 sq ft house and his hot water. Man does he go through the wood. Seems like everytime i call him he's cutting wood to fill the stock pile. Have seen snow sit on top of his hardy in the winter and only melt around the stack and the other pipe. Maybe he's feeding it to much green wood? He was curious to see what you had done with yours and how it has helped.

I run from the owb about 230 feet to the house (about 1900 sq ft) through the heat exchanger then back 220 feet to the garage (1800 sq ft) through another heat exchanger then about 30 feet back to the owb. Also another set of lines for the hot water. I didn't know any better at the time and used 3/4 inch pex. This year I removed the stainless steel and 1.5 inch insulation and framed (with treated wood) and put 9 inches of iso insulation (3 layers of 3 inch) on it and then metal to match my garage/shop.

I understand now, i bet it loves wood. Thats a long pull on 3/4. Guess if we all knew now what we didnt know then life would be a lot easier wouldnt it. Thats why i am reading almost every post on the owb's to learn from other people so i can get a good setup that will hopefully last me a long time, maybe it will pay off

I also have a hardy in need of new insulation. do you have any more step by step pic you'd be willing to share

I didn't take to many pics but I will see if I can find the ones I did take and post them.

Looks like you framed around it using treated lumber. Using that frame to suport the insulation then attached metal to that frame also. very nice going to have to try this one myself.

That is what I did, my next mod is to put a new chimney on it and drop it down into the firebox a few inches so the heat can't go straight out the top.

I insulated my entire new construction home with reclaimed ISO board. It had holes in it from its previous life so I had a spray foam contractor flash an inch over the top of the entire install. 3" is r-22 so you are not loosing anything if your install is tight. I believe 3" is well over $30 a sheet new.
