Re: What is the future of Hydronics?
There are probably some places that could use solar thermal, but I dont imagine they get much snow.
A good way to make heat for a pool or dhw in the more southerly lats perhaps ?
Im still trying to figure out if they're going to try migrating bits of the existing natgas piping network to hydrogen at some point.

Re: What is the future of Hydronics?
My crystal ball says changes in the distribution, sales, and installation/service models will affect your career more than traditional fuels vs electric and hydronic vs forced air.
Disruptive change is coming to this industry.

Re: What is the future of Hydronics?
Sadly, I think the future for any fossil fuel-fired heating equipment looks bleak. I believe it's based on the premise that electricity is less hurtful to the environment, which I believe to be wrong.
Hydronics are the most comfortable heating method, safe to operate, and very efficient.
Hot Rod is right, there is big money being invested into air to water heat pumps

Re: What is the future of Hydronics?
I think the future of hot-water hydronics is commercial, district heating, and snowmelt. It's shrinking quickly for residential in favor of heat pumps and geothermal.
Re: Radiator Size Weird For Location
The calculcator states this is the heat loss and powerv required based on my particulars. I'm guessing next I need to figure out the length of the pipe back to the boiler? This radiator is on the first pipe coming out by itself and is wrapped in encapsulated asbestos for insulation. 
Re: Vitodens 100w-b1ka
Set point adjusted to 70. 700 sq feet. 9.5 ceiling. Temp runs at 180F. Could possibly be air. Has taco 4900 air scoop. Have bled BB. Boiler BTU should be well sufficient. Listening to system pump sounds like there may be air. Air scoop screw is open. pressure #13. Air scoop possibly stuck. Not sure.
Re: Vitodens 100w-b1ka
I agree with everything your saying about the curve. Looking at adding more ft of BB in summer. Just wondering if the internal pump should be set slower. Has primary secondary with close tees. -28 C here right now. Has trouble getting indoor temp to 21 C.
Re: Vitodens 100w-b1ka
A well designed system using fin tube should use a 2.0 curve. The curve adjustment will raise or lower the heating output of the baseboard. If a curve of 2.4 is required, the footage of baseboard installed may have been originally sized for a 180 degree water temperature, instead of 140. When designed for 140, the boiler will be in condensing mode most of the time. It's not uncommon to have to raise the heating curve when extremely cold weather prevails.
Re: Vitodens 100w-b1ka
What kind of heating do you have? Radiant? Radiators? Hydroair?
Do you have an outdoor sensor mounted on the north side of the cabin?
You may need to adjust your heating curve. I wouldn’t play around with the pump speed just yet.

Re: Header, because
Those Slant Fins make very dry steam, I suspect due to the unique internal path of steam in the boiler through the full depth of the really wide end section and the internal baffling. Also really easy to get a good skim. Probably the best Cast Iron boiler design on the market.Unfortunately, they're no longer on the market. R.I.P., Slant/Fin.
