Did it, done it, got the t-shirt. Use a Biasi 3-wood running on coal. The Samson thermostatic draft control is the missing link for safety. Also a...
Got anything to back that up? Did a salvage on a copper/iron system. The steel panels failed en masse in 3 years. All iron parts showed extensive...
I have a 3-wood6. I use sub-bituminous coal. I heat 3400 sq. feet, off-grid with ~16 watts continuous power requirement and 5-6 tonnes of coal per...
I got 15mm TRV's on my cast rads. It was impossible to find metric fittings/adapters so I had a machinist ream the valves to 5/8 inch. They were...
Any outfit that won't share the analysis with is shady. Even if the copper is isolated from the system with dielectrics, it still corrodes (albeit...
Start with the easiest thing - you said your guy told you the water was "good". Define "good". What made it "good"? . One question - does your...
Use a product called "radsnaps" to protect exposed pex from sunlight. DO NOT put copper anywhere near those steel panel rads or cast rads if you...
Trying to remember where I found a gas water heater with an indirect coil in the BOTTOM of the unit. I have found ones with a space heating coil near...
A Caleffi Solar will do 3gpm at 10' of head. But its drawing 40 watts to do that. And thats at 24 volts. But 24V is the way to go. 12V is fine for...
As stated, plumb multiple pumps in parallel in your case. That is assuming an El Sid can pump much against that head. You already shot yourself in...
Its what happens when you turn loose a city plumber in the backcountry and money is no object. I heat about half their sq footage in a similar...
I found this website cruising around. It some backcountry lodge. Whoever installed this mess must have been getting paid by the elbow. To top it all...
How do you sell something to an American? Make it B I G. Huge, bigger than all the rest. It don't matter if it works better or even makes sense, just...
That would be great. I'm having a devil of a time finding formulae for gravity systems. I found a few @ engineeringtoolbox.com. I am trying to figure...
That Sieganthaler system is interesting. But the 40 watts consumption was only on the house side. With the 2 other circs, there would be more usage....
Thanks guys. The Siegenthaler articles are great. I've checked out the Wilo ECO pumps and the Liangs. Tough choice since 24VDC and 120AC is...
Considering tackling an off-grid install. Power consumption is a concern. I tried unsuccessfully to convince the client to install the boiler in the...
I'm not sure why they are marketing this unit as a wood boiler. Where it really shines is on soft coal, thats what its made for.
Been lurking for years, this post prompted me to register. I've worked oil & gas, pulp mills, concrete plants, water treatment, built my own boiler,...
