Title: Bottom insulation
Post by: evilpotato on November 23, 2009, 09:28:49 AM

Just got a new 175 and was wondering what others are doing to insulate the bottom of the boiler.  Any suggestions about what works and what doesn't would be helpful.

I used 2" thick roof insulation board I picked up on a construction sight. Cut some pieces of wood to prop up aganist insulation to hold in place. Built wood frame and insulated with 1" foam board then installed metal siding around outside. Put 4 2" round vents two on each side just to give a little fresh air under OWB.
I would think any type board insulation would work.

Thanks mikenc, that's pretty much what I had in mind, too.

Bruey, the bottom of the stove isn't insulated.  The installation instructions tell you to insulate it yourself.

souonds kind of strange doesn't it..they think the stove needs the extra insulation but they don't do it..they tell the customer to do it...read the warranty also..you  may have  voided the warranty by altering the stove?

Evilpotato, is right there is no insulation on stove bottom from factory. Just outside water jacket. You will loose a lot of heat unless you insulate. I realy don't understand why bottom is not insulated from factory.  They recomended using some type rigid insulation, cutting to fit  and blocking it up to hold in place. I set my stove on 4" cap blocks to get door a little higher plus made it easier to insulate bottom.
