Re: Our FIRST residential radiant window project (ME)
I know my walls have a higher delta t from inside face to outside face. Especially the lower the outside temp gets.
Heating the window area to negate its losses has always been in the history of hot water heat. Why do you always see Rads in front of the windows in the old victorian homes with hot water heating.
Yes you are right in reference to the cost to operate electric verses gas. But it depends on where ya live to the cost of those kilowatts, and whether or not this is an alternative heat sorce.
I believe Marks thinking goes way deeper then just off setting the heat losses of a window. He is more excited about the fact that there is a solution out there to a problem in heating these super insulated homes.
The straight forward RFH tends to be a little over powering in these homes. Couple that with the fact that to keep conventional RFH tamned enough for such homes they lose their cozy warm feet luster.
The only solution is to cut down on the area of radiant,and raise the temps to get that cozy feeling back which means the RFH has to be strategically placed to benifit the warm feeling floor to the occupant. That can create another issue... who knows where furniture will be for the next century in the home.
Since windows are the greatest heat loss in any structure why not heat them its still radiant, a heated window on a 10* day would probably give the same cozy effect to an occupant as RFH, maybe even better. This glass goes farther than off setting losses they will heat to a higher temperature than needed to off set the windows losses.
Who would think that one day it may be said, we need to add another window to meet the load of this room.
I for one think the applications are endless. The one hurdle is operating, and product costs. But as the dino juice supply dwindles there are not many alternatives to electric yet on the horizon besides hot water solar, and when you get alot of sun you ususlly don't need much heat.
PV panels are cost prohibitive for something of this high of wattage.
Think outside the box on this one I think it will be big.

Re: Radiators make my apartment unbearable during winter
Maybe ask the landlord about moving the thermostat to one of the apartments. Or at least installing sensors in apartments. Are there radiators in the hallway? If not, makes sense that apartments are overheating. Unheated hallway will always be colder than heated apartments (and possibly over radiated apartments).
Re: Radiators make my apartment unbearable during winter
Jamie Hall, please refer to my comment at 4:08 pm.
To all of you saying stop complaining, I realize others have it worse. Asking to have a dwelling in reasonable temperature parameters is not out of line. It’s a matter of ethics and general respect for the living conditions of human beings. If living in 80 degree temperatures is acceptable to you, then you’re welcome to adjust your own thermostat. Or, put your money where your mouth is and let’s trade houses.
I clearly asked for help with understanding the mechanisms of a boiler system with radiators and when repair is necessary. I did not ask for your opinion on what I should find acceptable.
I have everything documented from the last two years. Thought I’d save myself some research time by consulting experts. Didn’t realize this was The View for some people.
And, yes, both Eds seem to be redundant.
Thank you mattmia2 for the relevant commentary.
It’s not section 8 housing, but thank you for revealing your bias.
It’s amazing how I came here for advice relevant to a heating system and got the clicky preteen treatment for free from some of you.
This must be the highlight of your week. Inviting others to ask questions about heating and putting them down because you can’t help but assert your opinions outside of the subject. I’ve never known people worth while that practice behavior like that. You must feel so big.
Cheers

Re: Furnace fan will not work
Sorry but no it wont. The transformer only supplies power to the relay.

Ed's blanket solution is the fastest, cheapest fix to this problem if closing the valve doesn't do anything. My opinion only!
Re: Old copper pipe smaller than todays 1/2"
Hi, Sometimes silver solder is the simplest approach to burst tubing. I've repaired many frozen solar collectors this way.

Re: Its hot in here 84deg but I am a lot hotter
Like Bounty paper towels. They sell regular, doubles triples. Compared to what??
Re: Old copper pipe smaller than todays 1/2"
Possibly 3/8 OD that expanded when it froze. That is common with hard drawn 1/2" in homes when they freeze.
I've used a flaring bar to size it back down to put a fitting on.

Re: Need advice: What type of HVAC system & capacity to install, 3-bedroom house
Agree that HPWH have a way to go in my opinion. I don't think a GHWT is that bad yes there is flue gas loss. I used to shut the one off at my house when I went on vacation I would turn it to pilot and the water was still warm a week later with no one drawing on it.
Electric is better at holding heat but with higher operating cost.
I see nothing wrong with an indirect. You supposed to maintain temp in the indirect not the boiler.
