After having a new oil-fired hot water boiler installed, I’m
considering the value in replacing some of my convector radiators with
cast-iron. But, not sure if it's worth the hassle. Which would feel
more comfortable and/or be cheaper to run in the long run? For
example, convectors require shorter more frequent boiler firings to
keep the temp steady in the house. And although cast-iron radiators
require longer boiler firing time to heat up, they stay hot longer.
Sounds like it’s an even wash either way, but your comments are
appreciated.

Only some? If they are on the same zone you can wind up with uneven heat.
While I personally like cast iron radiators for the heat retention, I'd
not bother with the change. I don't see any energy savings as a Btu is
a Btu,but there may be a little comfort difference in some places if you
have any drafts.


Cast iron radiators take up a lot more space than convectors (especiall
fllorboard convectors). You'll miss that space if you convert.
