Baseboard mixed w/cast iron rads

Glen_7

I am moving into an older home in October that currently has an older gas fired atmospheric boiler and an older hot water heater. Since I will be replacing these with more efficient units, I thought it would be a good time to look at the entire system before the painters, etc. do their work. Currently the emitters are baseboard throughout. I currently have one pipe steam in my old home and love the cast iron rads in both comfort and appearance.

Here are my questions as I don't know much about h/w heat:

1) Can I mix the existing baseboard and add either cast iron radiators or newer Runtal or Myson style units together. I don't feel the need to rip apart the entire house, but radiators might look nicer in the formal areas instead of the baseboard, which will be fine for the second floor bedrooms, kitchen, etc.



2) Does a mod-con boiler make sense with baseboard emitters. I was under the impression they worked better with high mass. I don't want to go for the extra bucks if it won't yield any improvement over a modern standard boiler or EK System 2000.

I am not sure now how the house is zoned, if that is necessary info.

Thanks.

Not

You can mix radiators and baseboard,just don't do it on the same zone. A condensing boiler will work just fine on most existing BB systems,they're almost all over radiated. BNL did a study on BB and condensing boilers,I can't post as it's a PDF.Email me if you want to see it

recommends that you put their rads after the convection basboards if on the same loop.
