Radiant Wall Panel work in this space?

D107

literature says they're compatible with cast iron rads, meaning I guess I can keep it on the same loop and temp which saves me the trouble of a radiant loop. looks like the vertical column choice would fit right in that space.

My only concern would be if they're not cast iron how long they hold the heat compared to the CI rads I have. I don't plan on continuous circulation at this point.

thanks,

David

12.5\"W x 40\"H x 3.5\" Deep Indent in Kitchen Wall

Very limited on space in new kitchen plan. Have to remove old ci rad 53EDR. Heat loss is 1500 btu. Like to keep the 3 to 1 load to loss ratio for low supply temps--at least for the rest of the house-- when I upgrade boiler someday. Instead of new CI rad, I thought that that indent is a perfect place for a radiant wall panel if I can get it custom made for that size.

OR, perhaps a toekick size radiant panel that I could wrap around under the floor cabinets. Don't know what the output of that is per linear foot. Probably have less than 20ft of linear space for that. I know some don't advise having heated toe-kick area near sink since heat against your feet might be umcomfortable.

I'd prefer not to do a staple-up below kitchen.....if none of this is possible I can live with a custom made CI rad made by www.oldcastironradiators.com

OR How about radiant tubing behind the crown molding atop the wall cabinets at near ceiling level--and behind the window frame molding and under countertops?

Thanks for any thoughts,

David

Runtal makes vertical wall panels that would work in this space.

Runtal

I'd go with Runtal myself. Fifteen hundred BTU isn't that much; Runtal models have options for double

and triple

thickness radiators so you can get a hight output from a small footprint radiator.

PS And this rad would be first on a series loop

of cast iron rads totalling about 43KBtU in case that makes a difference. Too bad system was piped in series years ago when they changed from gravity system.

Series Loop

You would have to look at the pressure drop through the radiator you choose and make sure your circulator can handle it along with the flow needed for the other radiators, which doesn't seem to be too much. The calculations are pretty easy, but if you don't know how to do them, check back with us here or call Runtal.

The steel Runtal radiator won't hold the heat as long as your CI rads., but in my opinion this does not make an appreciable difference.

Balance valve

If you could have future access a balancing valve (rather than monoflow tees) through the rest of the series loop would allow you to control the diversion of water thru the new Runtal. I like the recess application. Don't "fill" the recess too much to stop convective heat transfer. A balancing valve on the supply or return to the loop beyond the Runtal could divert your 1500 Btu needed providing you can can pipe the supply or return from the Runtal to the loop between the boiler and the first CI rad. If you piped in series with your 43M I think it might overheat in relation to your CI.

under the countertops

Are you going with granite? Heated countertops work great, are the most comfortable, and the quietest.

runtal radiator wall panels as replacement to cast iron

Hi:

I am renovating my house and have limited space in a few areas on an exisiting hot water boiler cast iron from '20s radiator system. house gets real good heat balance now. I want to replace a few radiators with runtal wall panels for look and slimness. How do I calculate btu from old radiators- and should ZI be concerned about heat loss compared to old radiators?
Thanks,
Mark
