Looking for advice on new Radiator choices

I am getting ready to do a major kitchen renovation. I have to move two existing radiators which are original to the house. They are the convector-cover style. They are both 2 feet high by 3 feet wide. One is in the kitchen, one is in the dining room on a wall that is going to be removed.

The kitchen has been one of the colder rooms in the house. I had installed a 10 section gov-ray cast iron radiator in my bathroom 3 years ago and I love it. It is now the warmest room in the house.

I'm trying to decide if I should go with the cast iron rads in the kitchen/dining room, or the biasi ecostyle steel wall mounted panel radiators. Or maybe I will just get one cast iron for the kitchen, and just re-locate the convector cover in the dining room? Trying to do this all on a budget too.

The biasi rads seem to have similar btu outputs to the cast iron, but i'm not sure because they don't give the water temp that corresponds with the btu ratings.

Does anyone have any experience with these?

Outputs based on 180 F Supply Temperature, 160 F Return Temperature
and 68 F Room Temperature

BIASI - Ecostyle Radiator Panels

Just had to look at the information sheet!

http://www.qhtinc.com/pdf/EcostyleLiterature.pdf

and correction factors can be found here for whatever temp you would like to run at.

Good practice says not to mix emitter types on the same zone. (e.g., don't have cast iron rads and fin-tube baseboard/convector on the same loop).

Cast iron rads give off a great heat. Sizing panel rads for similar output also a good way to go.

Could you explain why this is?

Thank you, I did look at the literature, but I missed the page that specified temperature.

Because the different emitter types heat and cool (and give off heat) at very different rates. Baseboard cools within minutes of stopping water flow. Cast iron rads take much, much longer. So imagine a zone with both, and the room with the thermostat has one or the other....

That makes sense, thanks. Any ideas how I can help warm up the kitchen? That is why I wanted to use the cast iron rad. With the new layout I'm losing wall space and will only have 24" of open wall for a radiator. The current convector is 36". I have already added insulation to the attic above.
