General Outdoor Furnace Discussion / Tall Chimney

« on: November 12, 2019, 11:25:08 AM »

I have a basic question to see if anybody can answer.  Is there any negative effects of having a rather tall chimney/stack?  Stove is pretty close to house and when the wind is blowing the right direction, it can get pretty smoky all around the house.  I'd like to try to get the exhaust up a little higher to see if it helps.  It's already up about 10 feet, the top of the house is about 25 feet.  Any suggestions?

General Outdoor Furnace Discussion / Concrete Slab Inlet and outlet temps

« on: November 29, 2018, 07:35:51 AM »

Anybody out there running solely a heated slab, I have a question.  What kind of temperature differentials are you seeing in your system between the water temps you have entering the slab and the temps you have exiting the slab.  I know that there are so many variables here, but I am really curious what others are experiencing.  I heat a 2400 sq ft. slab, 8 circuits, all are the same "zone", however I do control water flow differently in some of the circuits.  I am running a standard wall mounted digital thermostat (air).  After some trial and error, I have landed on 120 degree water going in the slab, and almost always, I have 79-81 degree water coming out of the slab.

General Outdoor Furnace Discussion / Thru the roof stove pipe

« on: August 28, 2018, 02:46:36 PM »

I have a Hardy H2, this summer I have installed a metal carport over the top of the stove to keep me and the wood out of the weather.  I am looking for ideas / suggestions on materials I should use to get my stove pipe through the roof.  Metal roof only, no wood anywhere.  One worry is how stinking hot that pipe can get sometimes (when really cooking, the stainless stock pipe is glowing red).  This makes we wonder and worry about rubber-type boots and such.  From the stove to the roof-line will be approx 2-3 feet.  Let the suggestions fly.  I am no professional, but I'm not afraid to try!

General Outdoor Furnace Discussion / Need to cycle my pump on and off?

« on: November 22, 2017, 12:04:24 PM »

I have a Hardy H2, heating the concrete floor of a 40x60 shop/house combo.  I have an 8 circuit, manual flow control manifold, I would like to add a thermostat to my system so that it will shut off my pump when my in-house temp gets to a certain point, then the pump will come back on when needed.  The floor holds the heat very well, but is seems like I need to slow down my burn cycles.  I have my aquastat turned down to 160 from 170.  The aqua stat turns the blower on/off.  I have most of my manifold valves just slightly turned, feeding as little as 0.2 GPM per circut.  As it is now, water entering my manifold is about 155 degrees, and exits the manifold at about 85 degrees.  It seems like it is all I can do to get a 12 hour burn, but yet I really don't need all of the the heat it is providing the floor.  I'm just looking for suggestions. Currently, with very little cold weather so far, "garage" temp has been around 72 degrees and the "living" space has been around 74 degrees.  Wife likes the temps, but I feel like I could slow my burns down and save some wood.
