Re: What likely caused this horrible corrosion on copper return from cast iron radiator?
What insulation? What material is the hairline crack in? I posted a close up photo below the floor that may show iron going to copper? What is the blue-green pipe going under the floor?

Re: What is the future of Hydronics?
I think hydronics and steam will sooner or later sadly end up like the dodo bird gone like ancient Mayan history being the smarter and wiser one have all the fantasy worked out on paper or do they ? Does it works in practical application ,let’s look at that wagon w everybody in at its heavier then the cart or wheels can handle or the road for that fact . The major fact is that the lowest possible economical group will be the most effected not the wealthy they will still be on fossil fuel and they will work out there deal to get some one else to pay mainly us . I think as time goes hot water will and has been get edged out of the new home market . Everybody wants it all in one basket and builders and gc s what the highest profit in there pocket answer air based system sure they use more electric but the future say electric will be produced from one arse if you believe that I’m selling stock in dirt and air . I highly doubt the great thinkers of previous eras would believe such ,the division of the human condition and lack of unity and separation of complete groups by a pin on label is further manipulation to divide humans isolate them to more easier conquer and rule . Time goes on but the craving for some to force there will on the masses of humanity continues remember it’s easy to win when you divide the groups and feed them miss information to separate them further . Used by gangis khan to conquer the world ions ago . Peace and good luck always based on reality clammy

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.
