Well said!!! I agree 1000%!

Ultra-Fin Radiant

Just looking for any experience others have had with this or a similar product. The company I am now working with uses it and I've never seen it before. It uses pex run perpendictular to the floor joists, and you attach thin aluminum "radiating" plates to it. How does this compare to a traditional staple up job in operation and ease of install.

Thanks!

It's OK...

as long as you don't mind having a system operating between 160 and 180,,, I do mind, so I don't recommend its use. I design every system like I'M going to have to pay the utility bills, and I'm a tight wad:-)

Here's a concept. A large block of concrete with a ton of 1" PEX buried in it, filled with concrete. You heat it during the day using solar, then extract the heat out with a heat pump when needed and subject the mass to a major (32 to 140 = 108 degree delta tee, versus the typical 30 degree delta tee)delta tee. (Ya got that?;-)You get 3 times as many btus out of a small storage system and keep your gas meter shut down. For the people back east paying $0.15 per KWH, that would mean taking thier per therm cost from almost $4.00 and knocking it down to around 1 buck a therm.

That could cause a major reduction in energy buckage outlay...

I'm going to call this concept the Big Thermass Storage Cell. And you can use it if you want:-)


If I were you, I'd look at some low temperature applications. DOn't forget to look up, and sideways. Ceilings and walls work excellently as radiators and LOVE to operate with temperatures of around 120 degrees F. The lower the temperature of operation, the better.

best heat storage?

does cement hold more heat than water? in sacramento they told us water held the most. i thought it was the other way around. bob

Questions and Concerns

Specific Heat of Water vs. Concrete

Water holds twice the heat per cubic foot. Cheap too! Concrete is nice because you can build your basement floor out of it. Water is nice because you can pump it around and put the heat where you need it.

didto - especially in bedrooms

what good is radiant in a bedoom if you are on top of a bed - the infrared light cant reach you, - so if you cant put the radiant in the ceiling - then put up a huge myson 28x63 inch radiator on the wall, 20 inches off the floor, with the smooth plate cover, and run 110 degree water to it, and walpaper a nice mural on it so that you wife dont kill ya,
and have a nice day... http://www.mysoninc.com/Pages/Radiators/Select.html

Drawbacks

There are two major drawbacks....high temperature, and drilling all those holes. Even staple up onix must work better. At least that has a little (very little) conduction. Ultra-fin seems like a tedious installation. Also it's nice not to have to perforate the joists. It seems people will do anything to avoid using plates. I dont understand that. Is it all $$? But if it is money, what about installation time? I'd bet dollars to donuts that thermofin doesnt take any more time to install than ultra-fin. What about fuel saved by running a condensing boiler? Pay a little now, save a lot later.

I will be doing a job where there are so many nails sticking through that the owner is going to spend the summer with a grinder. I might just suggest the fins instead.
