The same pump has been running on my OWB for 20 years. About a 120 foot total loop. 15 of those years was only seasonal 24/7 about 5 months out of the year. For the last five years, since i added the domestic hot water then the clothes dryer the Owb burns year round and pump also runs...

I've had decent success splitting gum from the outside in. Working around the outside perimeter knocking chunks off working in towards the middle instead of splitting from the middle like you normally would. With a hydraulic splitter this works ok but still not worth it. Gum burns like crap and...

There is no change in the room temp it stays the same temp as the rest of the house. It works the same as it did on electric it just pulls air through a water to air heat exchanger instead of the electric heating elements then vents to the outside.

I was unable to make it work effectively with the electric heating elements still in the dryer. So i can not select between electric and owb to dry clothes as I mentioned i was trying to do in my last post. However we have been drying clothes without the electric heating elements solely on the...

What you want to do would be pretty simple for a qualified HVAC tech. You could wire the boiler as the first stage of heat and the heat pump for the second stage and the electric heat for third stage heat. This would probably require a different tstat and because the heat pump would be stage two...

In the installer configuration of the t-stat you should be able to set the dead band between stage 1 and stage 2 heat. If you set this for two degrees the second stage heat will not come on until the space temp is two degrees below set point. If memory serves me correctly this dead band is...

I used a project computer called raspberry pi so i could monitor my temps remotely. This definitely wasn't easy but it does allow me to check temps from anywhere via my smart phone. Here's a screenshot of the web interface once i figured out the code and how to write it adding sensors was...

I heat an 1800sq ft early 1900s pretty well insulated farm house, hot water, and clothes dryer for a family of 6 with a home made OWB. I burn year round and my annual wood consumption is 14 cords. But that is mild SE georgia winters.

Oops......... I divided instead of multiplying..... 480 is correct

I have a home made OWB but it is built very similar to the CB. The draft fan and the digital ranco control I'm using draws 1 amp the pump draws .75 amp and the indoor air handler draws 2.2 amps. The entire heat system draws just under 4 amps at 120 volts. That works out to 30 watts. I heat the...

OWB burns year around for clothes drying and hot water and is the only source of heat we have. Upper 20's and mid 30's forecasted for SE Georgia in the next few days, it'll be getting a good workout

The typical indoor fan off of a furnace draws about two amps at 120 volts on high speed. That calculates to 240 watts if you ran it for one hour it would use 0.24 kilowatt hours. 12.5 cent per kwh is about the national average. So that means you could run the fan for four hours for about 12.5...

Nice van!!!!! Maybe you could modify the boiler to double as a gasification unit to fuel it!

Heres some pics of mine. Its 13 years old now and i was about 16 when my dad and i build it (i did most of the fabrication as i was working in a machine shop at the time) i have almost completed a major over haul. all the piping and controls are new and nothing has been insulated yet or the...

I joined arborist site a few weeks ago looking for info on this very subject. I have heated my house and hot water with a home made owb for about 15 years and heating the cloths dryer with it has been on my mind for a while. When i built my owb i had never seen or heard of them before (i thought...

100% silicone has always worked well for me
